Java 5 Features

Java 5 Features

Generics
This long-awaited enhancement to the type system allows a type or method to operate on objects of various types while providing compile-time type safety. It adds compile-time type safety to the Collections Framework and eliminates the drudgery of casting. Refer to JSR 14.
Enhanced for Loop
This new language construct eliminates the drudgery and error-proneness of iterators and index variables when iterating over collections and arrays. Refer to JSR 201 .
Autoboxing/Unboxing
This facility eliminates the drudgery of manual conversion between primitive types (such as int) and wrapper types (such as Integer). Refer to JSR 201 .
Typesafe Enums
This flexible object-oriented enumerated type facility allows you to create enumerated types with arbitrary methods and fields. It provides all the benefits of the Typesafe Enum pattern (“Effective Java,” Item 21) without the verbosity and the error-proneness. Refer to JSR 201.
Varargs
This facility eliminates the need for manually boxing up argument lists into an array when invoking methods that accept variable-length argument lists. Refer to JSR 201.
Static Import
This facility lets you avoid qualifying static members with class names without the shortcomings of the “Constant Interface antipattern.” Refer to JSR 201.
Metadata (Annotations)
This language feature lets you avoid writing boilerplate code under many circumstances by enabling tools to generate it from annotations in the source code. This leads to a “declarative” programming style where the programmer says what should be done and tools emit the code to do it. Also it eliminates the need for maintaining “side files” that must be kept up to date with changes in source files. Instead the information can be maintained in the source file. Refer to JSR 175.

How to create Liferay Plugin Portlets

1. How to Create plugin portlet by own

Navigate to your portlets directory inside your pluginsSDK

Eg.

/home/kanakarajr/liferaypluginsSDK5.2.1/portlets

use ./create.sh “portletname” “portletdisplayname”

Eg.

/home/kanakarajr/liferaypluginsSDK5.2.1/portlets> ./create.sh “MyPluginPortletTest” “My Liferay Plugin Portlet Test Work”

Now you have created files necessary to create plugin portlet.

2. How to import portlet directory in your Eclipse IDE

Navigate to your pluginportlet directory .. just created

/home/kanakarajr/liferaypluginsSDK5.2.1/portlets/MyPluginPortletTest> ant setup-eclipse

This will create eclipse project files

Import this into your workspace as project.

Using File-> Import -> Existing Projects Into WorkSpace -> Browse your directory -> Finish

3.How to deploy these portlets

3.1 Create build file

Inside your pluginsSDK modify build.properties by making copy of build.properties, rename the file to build.user.properties.

Eg. build.kanakarajr.properties

location: /home/kanakarajr/liferaypluginsSDK5.2.1/

3.2 Configure server location in build.user.properties

Specify liferay tomcat location

Eg.

app.server.dir=/home/kanakarajr/software/liferay/tomcat

3.3 Specify Auto Deploy directory for your plugin portlets

Eg.

auto.deploy.dir=/home/kanakarajr/works/liferayautodeploy

3.4 How to build portlets

Navigate to your pluginportlet directory and use “ant deploy” to build portlets

Eg.

/home/kanakarajr/liferaypluginsSDK5.2.1/portlets/MyPluginPortletTest> ant deploy

finally you will get message like this ..

12:16:45,642 INFO  [PortletHotDeployListener:351] 1 portlet1 for MyPluginPortletTest-5.2.0.1 are available for use

Now you know how to build liferay plugin portlets and how to use it in EclipseIDE and finally how to deploy the developed portlets into liferay

How to Use Custom Styles to Flex Components

1. Create Style for Your Component ..

Use this URL to simplify the StyleExplorer for Flex Components ..

Style Explorer

2. Create a style css file eg. CustomStyle.css

inside your project src .. eg:  Project\src\assets\styles\CustomStyle.css

Create Styles for the components, You can do this by Creating Styles from Style Explorer and copy the text [ css style ].. from RIGHT MOST PANEL… Named CSS

Eg. CustomStyle.css

/* CSS file */
.TabNavigator {
tabHeight: 30;
horizontalGap: 1;
borderThickness: 1;
tabStyleName: “myTabs”;
firstTabStyleName: “myTabs”;
lastTabStyleName: “myTabs”;
selectedTabTextStyleName: “mySelectedTabs”;

Liferay FusionCharts Integration

How to do ” Liferay FusionCharts Integration”
Its easy simple …
Problem:exists:
You might given the syntax to include flash chart swf, xml [say for eg ]

I pasted Only Snippets in the html/jsp file used to include fusion charts ……
1.
<script language=”JavaScript” src=”js/FusionCharts.js”></script>
<link  rel=’stylesheet’ href=”Contents/Style.css” />

2. <script type=”text/javascript”>
var myChart = new FusionCharts(“Charts/StackedColumn3D.swf”, “chart1″, “580″, “300″, “0″, “0″);
myChart.setDataURL(“Data/Summary/Revenue2005.xml”);
myChart.render(“chart1″);
</script>

the problem

In portlet the location of swf, xml file cannot be known ..

Solution is to let portlet identify the location of swf/ xml file to display charts

Solution

1. Get the location of the portlet by

String pathPrefix=renderRequest.getContextPath();  //in jsp

1.<script language=”JavaScript” src=’<%=pathPrefix%>/js/FusionCharts.js’></script>
<link  rel=’stylesheet’ href=’<%=pathPrefix%>/Contents/Style.css’ />

2. <script type=”text/javascript”>
var myChart = new FusionCharts(“<%=pathPrefix%> /Charts/StackedColumn3D.swf?registerWithJS=1″, “chart1″, “580″, “300″, “0″, “0″);
myChart.setDataURL(“<%=pathPrefix%>Data/Summary/Revenue2005.xml”);
myChart.render(“chart1″);
</script>

Open-source Web applications, PHP vs. Java

Part 1:

It is common knowledge that PHP does well in the open-source Web applications space. PHP has numerous representatives for most application categories, and for some it provides a clear leader, like WordPress. On the other hand, most Java counterparts have apparently failed to reach the same popularity.

Below is an overview of the existing open-source PHP and Java implementations for the following categories of applications: forum, blog, wiki and content management systems (CMS). These are among the most commonly used types of on-line software.

Forum Engines

There are lots of PHP forum engines in the open-source software arena, including:

• phpBB which has 700+ mods and is the winner of the SourceForge.net 2007 Community Choice Awards for the Best Project for Communications category,
• vBulletin with 1000+ mods,
• punBB having 300+ projects and 150+ styles.

Notice the large amount of plugins for each of these projects. This denotes a large and healthy user base, devoted to both using and extending the core application.

Java has the JForum and JavaBB projects, but they seem to have very few users by comparison, not to mention plugin contributors.

Blog Engines

In the area of blogging, the PHP based WordPress is extremely well spread. Chances are that virtually any blog you read is powered by WordPress. The project has 2000+ plugins and at least 5 dedicated printed books. No other PHP blog engine comes close to the popularity of WordPress.

For Java, there are two relevant open-source blog applications: Apache Roller and Pebble. Roller is more feature-rich, but that comes at a considerable price: large footprint and difficult configuration. It is an enterprise application focused on very large blogging sites (e.g. the Sun blogs), but it seemingly fails to satisfy small-scale needs. I have yet to find a plugin developer community around it.

Pebble on the other hand is focused on the other end of the spectrum, providing a much simpler configuration and lower footprint. But I still couldn’t find plugins.

Wiki Engines

In this category, PHP seems to have an overwhelming advantage. The MediaWiki project powers Wikipedia, the largest wiki by far. The project has lots of available extensions, of which 300+ are stable. There are lots of other PHP wiki engines one can choose from, but I just wanted to point out the most prominent one.

Java does not have too many production-ready wiki projects. In my opinion, JspWiki (with 50+ plugins) and XWiki are the most relevant. I wanted to mention SnipSnap as well, however it’s development is officially stopped.

Content Management Systems

Content management systems are a handy way of building dynamic sites instead of starting from scratch. PHP seems to provide everything one needs, including a healthy competition among its foremost projects. These are Joomla (2900+ extensions, 14+ books published) and Drupal (3600+ modules, 9+ books). There are also other CMS projects e.g. Mambo and the ancient PHP-Nuke.

Because in most cases CMSs are deployed on a dedicated server, Java should not be at a disadvantage in this category. There are several open-source Java CMSs to choose from: Apache Jackrabbit, Apache Lenya, Alfresco, Liferay, OpenCms, Nuxeo, Magnolia, Jahia etc. Among these, Alfresco (2 printed books and 20+ stable extensions) and Liferay (portlets based, 1 printed book, 25+ portlet plugins) seem the more popular.

A special note for the Java Content Repository API defined by JSR-170. Both Jackrabbit and Magnolia implement it. This means that third-party tools can access their repositories in a standardized way. It is a very good step towards ensuring that information stored inside a JCR compliant repository can outlive a particular JCR implementation.

For now, the JCR API does not seem enough however. The PHP CMS projects are continuously gaining ground, probably because PHP hosting is cheap and easy to set up, and because the projects themselves are highly usable. Take into account that DZone and implicitly JavaZone (the former JavaLobby) are running on Drupal. And I’m sure that Rick and Matt tried to choose the best option while not easily dismissing the Java CMSs.

In the second part of this post, I will try to explore the reasons for the current state and to figure out a way to change it. Meanwhile feel free to add your input to the above, the list of projects is far from exhaustive.

Part 2:

The first part of this article reviewed some relevant open-source Web applications in both the PHP and Java worlds. The conclusion was that there are massively popular PHP projects and somewhat popular if not obscure Java counterparts. I’m a Java fan and it pains me to discover this reality. The user comments also underlined this feeling.

Is it the technical merits of PHP?

In my experience, the technical merits of PHP are below those of Java as a language and as a runtime environment (standard API, virtual machine).

Compared to Java, the code quality of PHP projects has a faster decreasing rate as the codebase size grows. The root cause is that PHP was created to solve small size problems and this makes it difficult to manage larger projects.

PHP 3 and 4 had basic object-oriented features, while PHP 5 improved them considerably, both at the language and the runtime level. There are several PHP MVC frameworks to ease the structuring of larger projects, but these are most effective when running on PHP 5. Most popular open-source PHP projects still run on PHP 4 and tend not to use MVC frameworks at all.

Looking at the staggering number of plugins available for the popular PHP open-source projects, one could conclude that their code is easily understandable and that PHP has well-rounded application extension mechanisms. Well, not exactly true.

The typical PHP extension mechanism is procedural and works like this:

• list the subdirectories of the extensions directory,
• analyze the predefined directory structure for each extension,
• execute some predefined PHP files that should auto-register their resources and actions.

The greatest concern? no protection of the core code. All the important internal structures of the PHP runtime are map-like data structures to which the PHP code has full access: the global variables map, the functions map, the classes map etc.

As a long-time Java developer, I see these as drawbacks. But they don’t seem to reflect as such on these popular projects with very large user and developer communities. But if it’s not the language, what is it?

The execution models

Compared to Java, developing and hosting PHP projects is dead-simple because of the execution model.

In a typical setup, each request to a PHP application is handled by a separate Apache process that uses its own instance of the PHP interpreter. After handling the request, the process is killed with no garbage left behind. This sounds inefficient for high-concurrency usage, but works great in a shared hosting environment. If a hosted application has no active requests, it doesn’t use memory at all. Development-wise, each PHP script is written like every script instance (process) is the only one running.

The Java Web application model uses servlets and multiple threads to handle requests. It scales upwards very well, hence its success in the enterprise space. Problems arise if you want to host many smaller and less frequently used applications inside the same Web container, precisely because of the threads. Developers have to be careful about concurrency issues.

The process control mechanisms available at the OS level are vastly superior than those available for Java threads. The result is that a hosting provider has strict control over the resources used by each PHP request. On the other hand, a Java thread backing a request is an object that you cannot control once started: it stops when it wants to, it uses as much system resources as it pleases. The Web containers only have mechanisms for controlling the pool of threads.

The end result is that there are technical limitations in setting up a competitively priced reliable Java hosting solution. This brings us to two fundamental questions: do we need successful open-source Java Web projects suitable for non-enterprise use? Can Java survive without such projects?

Java can probably survive, but survival and flourishing are two different things. If the average present-day college student or hobbyist finds pleasure in using and extending open-source PHP (and generally non-Java) Web applications, I believe that it is only a matter of time until the effects are felt in the enterprise space: less enthusiastic Java specialists, less innovation, decreasing quality of products and so on. Some say that the effects are already present ? what do you think?

Instead, wouldn’t you like to run your blog on a Java-based highly extensible engine? Wouldn’t you like to build complex sites using a Java-based CMS with many high quality, readily available, easy to develop modules? Something that can be as small or as large as you want. I would.

Building successful open-source Java Web applications – your input is needed

In my opinion, there are three important premises for an open-source Web project to succeed:

• the intrinsic value of the project,
• the enthusiasm of its community (both developers and users),
• easy hosting.

If Java presence is to increase in the area of open-source Web applications, all three are needed. The first two items are crucial because valuable projects and enthusiastic communities can even help improve the existing entry-level hosting options.

The fastest way to obtain Java projects with the same functionality as PHP ones is by automated software translation. The company I co-founded has developed technology that allows translating PHP applications to Java. I have already talked about this while presenting the nBB2 project, the Java equivalent of phpBB 2. The migration algorithms can be customized to produce various output flavors, ranging from plain servlets and JSP pages to Web frameworks like Struts or Spring MVC.

We would like to translate more open-source PHP projects to Java, but this would be just a first step. The Java community would then have to step in by using and extending them.

In the comments following the first part of this article it has been suggested that Sun act and sponsor key open-source Java Web projects. I my opinion, Sun already provides the Java platform and an open-source stack to support such endeavors. It is up to the Java community to make proper use of the technologies at hand. I look forward to hearing your thoughts on this topic, both online and in person. Next week I’ll be at JavaOne, so if you are around feel free to pass by the Numiton booth 1224-8 in the startup row.

8. Now we need tocreate table book –

create service.xml inside “ext-impl”

<?xml version=”1.0″?>
<!DOCTYPE service-builder PUBLIC “-//Liferay//DTD Service Builder 4.3.3//EN” “http://www.liferay.com/dtd/liferay-servicebuilder_
4_3_3.dtd”>
<service-builder package-path=”com.ext.portlet.library”>
<namespace>Library</namespace>
<entity name=”Book” local-service=”true” remote-service=”false”>
<!– PK fields –>
<column name=”bookId” type=”long” primary=”true” />
<!– Group instance –>
<column name=”groupId” type=”long” />
<!– Audit fields –>
<column name=”companyId” type=”long” />
<column name=”userId” type=”long” />
<column name=”userName” type=”String” />
<column name=”createDate” type=”Date” />
<column name=”modifiedDate” type=”Date” />
<!– Other fields –>

<column name=”author” type=”String” />
<column name=”publisher” type=”String” />
<column name=”price” type=”long” />

</entity>
</service-builder>

9. run service builder — it generates service layer classes .

Liferay 5.2 Installation

Steps to Install liferay Portal

Required Softwares;

Liferay Portal, ant, mysql or any DB [ setup explained here for MySQL  and liferay bundle with tomcat 5.5.x]

1.Get JDK version greater than 1.5 and install , set JAVA_HOME

If OS Windows set in System Variables

JAVA_HOME= C:\JDK1.5; add this entry into PATH variable as %JAVA_HOME%\bin\;

For Linux .. SuseLinux

JAVA_HOME=/home/username/software/jdk1.5.0_14
ANT_HOME=/home/username/software/apache-ant-1.7.0

PATH=/home/username/software/jdk1.5.0_14/bin:/home/username/software/apache-ant-1.7.0/bin:/home/username/software/mysql-5.0.51/bin:/sbin:$PATH

export PATH JAVA_HOME ANT_HOME ANT_OPTS
2.Set ANT_HOME similar to JAVA_HOME in Windows [ for Linux follow the above]

3.Get liferayportal – now current version is 5.2.1 .

http://www.liferay.com/web/guest/downloads/portal  – Liferay Portal Standard Edition — get this

and extract to home/username/software/liferay52/

You can see data,deploy,tomcat-xxx, license folders

4.Get Portal source from

http://www.liferay.com/web/guest/downloads/additional

Bottom of the page under  grouping “Files for Developers” — Liferay Portal 5.2.1 Source

extract to  home/username/software/liferay52/portal52/

You can see some folders and properties files.

Now its time to create EXT environment and database configurations

i. copy the app.server.properties  and rename to  “app.server.username.properties”

app.server.username.properties —

1. set app.server.parent.dir=/home/username/software/liferay52

2.   ## Tomcat  ##

app.server.tomcat.version=5.5
app.server.tomcat.dir=${app.server.parent.dir}/tomcat-5.5.27
app.server.tomcat.bin.dir=${app.server.tomcat.dir}/bin
app.server.tomcat.classes.global.dir=${app.server.tomcat.dir}/common/classes
app.server.tomcat.classes.portal.dir=${app.server.tomcat.portal.dir}/WEB-INF/classes
app.server.tomcat.deploy.dir=${app.server.tomcat.dir}/webapps
app.server.tomcat.lib.endorsed.dir=${app.server.tomcat.dir}/common/endorsed
app.server.tomcat.lib.global.dir=${app.server.tomcat.dir}/common/lib/ext
app.server.tomcat.lib.portal.dir=${app.server.tomcat.portal.dir}/WEB-INF/lib
app.server.tomcat.lib.support.dir=${app.server.tomcat.dir}/server/lib
app.server.tomcat.portal.context=ROOT
app.server.tomcat.portal.dir=${app.server.tomcat.deploy.dir}/${app.server.tomcat.portal.context}
app.server.tomcat.log.dir=${app.server.tomcat.dir}/logs
app.server.tomcat.temp.dir=${app.server.tomcat.dir}/temp
app.server.tomcat.work.dir=${app.server.tomcat.dir}/work
app.server.tomcat.zip.name=liferay-portal-tomcat-5.5-${downloads.version}.zip
app.server.tomcat.zip.url=${sourceforge.mirror}/${app.server.tomcat.zip.name}

Don’t modify anything

2.similar to  app.server.username.properties copy release.properties and rename to “release.user.properties“

release.user.properties — changes

lp.source.dir=/home/username/software/liferay52/portal52

lp.ext.dir=/home/username/software/liferay52/ext

ant.installer.dir=/home/username/software/apache-ant-1.7.0

// comment plugins , eclipse if u dont need .. i will gine instructions how to add this ext into eclipse as a project

3.  DB configurations

Default database name for liferay lportal … if you want change

inside folder “sql” — sql.properties –    replace the database name whatever you want

eg: database.name=lportal52 // i named to lportal52  – if u dont want leave it – donot modify other than anything in this  file

Its time to set database association with liferay tomcat … to do this ..

Modify the portal.properties inside /home/username/software/liferay52/portal52/portal-impl/classes/

Open the property file and search for MySQL \\ by default Hypersonic is be configured

uncomment mysql properties …. after look like this

” #
# MySQL
#
jdbc.default.driverClassName=com.mysql.jdbc.Driver
jdbc.default.url=jdbc:mysql://localhost/lportal52?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false
jdbc.default.username=root
jdbc.default.password=’mysqlpassword’ “

// Dont forget to comment hypersonic properties

4. Final step is to build the portal

Open a console inside portal52

$$$$$$$ /software/liferay52/portal52>  ant clean start build-ext

after some time ~ 4 minutes for [1GB RAM witk Intel Core CPU ]

You will get build successful

$$$$$$$ /software/liferay52/portal52>  ant start deploy

Now the portal server is ready …

Navigate to $$$$$$$ /software/liferay52/portal52/tomcat5.5.x/bin>./startup.sh

..

.

.after som time u will get message like this …

INFO: Server startup in 58507 ms

5.Open browser type http://localhost:8080

default username ” test@liferay.com”, password is     ” test”

login and enjoy with liferay ….

6.Final set up for ext environment …

when  u build ext using command “ant clean start build-ext”

new directory    “ext”  will be created inside ” /home/username/software/liferay52″

If you want to develop portlets using ext environment …. dont forget to paste the  “app.server.username.properties” file into ext folder — get this from portal52/app.server.username.properties

open a terminal inside ext folder …

$$$$$$$ /software/liferay52/portal52/ext>  ant  deploy

after some time u will get message like

BUILD SUCCESSFUL
Total time: 1 minute 35 seconds

7. Importing ext into Eclipse

Open Eclipse IDE , choose import from File menu .. select ” Existing Project into WorkSpace”

Choose “ext” … and click finish …………..

Now i hope everything ready to enjoy with liferay portal , development environment has been set ………

In next Post we will see how to develope portlets from liferay-plugins-sdk
