NetBeans Struts2 plugin updates

NetBeans Struts 2 plugin updates

NetBeans Struts 2 plugin (http://nbstruts2support.dev.java.net)is not updated for a long time. I checkout the source code and made some modification to the latest NetBeans IDE 6.7.
1.Update Struts library to the latest stable version 2.1.6
2.Update to the latest web framework API。
3.Redesigned configuration panel and provide more flexible configuration options
4.Other modification to Struts 2.1.

Download here :https://dl.getdropbox.com/u/201666/nbstruts2.tar.bz2

Struts 2.1 provides next generation Filter to process request , and also provides a new optional Servlet .


If you like choose Struts Servlet to process request , you can check "Servlet"  radio box in the "Reuqest processed by" section in the "Main" tab.

This will generate some code like the following.



   <servlet>
        <servlet-name>struts2servlet</servlet-name>
        <servlet-class>org.apache.struts2.dispatcher.ng.servlet.StrutsServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>struts2servlet</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>


 
If you would like use Filter  to process request which is recommended by Struts , it will generate some code in web.xml.
 

    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

 

In the new Struts 2.1 , the StrutsPrepareAndExecuteFilter instead of DiispactherFilter. StrutsPrepareAndExecuteFilter has two variants, StrutsPrepareFilter and StrutsExecuteFilter. If you use other Filter together, especially the Sitemesh
Filter,StrutsPrepareFilter will do some clean action.

In the Plugin Support tab, there are some Struts2 plugin configuration are provided.
If you select Filter to process reqeust and use sitemesh filter at the same time.
It will generate the following code in web.xml for you.

  
    <filter>
        <filter-name>struts2prepare</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
    </filter>
    <filter>
        <filter-name>sitemesh</filter-name>
        <filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
    </filter>
    <filter>
        <filter-name>struts2execute</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2prepare</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>sitemesh</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>struts2execute</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

 



In the Main tab, provide a Development Mode checkbox . If you check it , it will add a constant to the struts configuration file. These options will benefit debuging struts2 application in the development phase.

  <constant name="struts.devMode" value="true"/>
  <constant name="struts.configuration.xml.reload" value="true"/>

 

If the Spring support checkbox is selected, it will add constant in the struts cofiguration.

  <constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory"/>


Struts will use Spring as object factory to create Struts object, include Action , Interceptor etc.
Beside this , it will add some configuration in the web.xml. It also create a new empty Spring configuration file.

 <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>

<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>


Convention puglin is a new plugin shipped with Struts 2.1, it adopt much concept from other plugin. Using this plugin , you can Java 5 annotation instead of xml configuration.

Convention has a optional parameter, You can input the actions package name , this will help struts at runtime to detect the Action class.
 
For Struts2 beginner, the best learning path may be learngin by example. If you select Create Example Application check box, it will create a simple example which is from the Strust source code.
