Question

In my struts2 web application for menus i am using struts menu plugin.I am using eclipse juno for my struts2 web application. When I write following plugin in my struts.xml it runs my project for some time but after some time it prevent my application to run.
My struts.xml as follows:

<struts>
    <constant name="struts.enable.DynamicMethodInvocation"
        value="false" />
    <constant name="struts.devMode" value="false" />
    <constant name="struts.custom.i18n.resources"
        value="ApplicationResources" />

    <package name="default" extends="jasperreports-default,struts-default" namespace="/">

        <action name="login" 
            class="net.viralpatel.struts2.action.LoginAction">
            <result name="success" >Welcome.jsp</result>
            <result name="error">Login.jsp</result>
        </action>
    </package>

     <plug-in className="net.sf.navigator.menu.MenuPlugIn">
        <set-property property="menuConfig" value="/WEB-INF/menu-config.xml"/>
     </plug-in>

</struts>

After that, if i cut that plugin code from my struts.xml and refresh my project and paste it again then it runs successfully for some time.After some time it again show error icon on my project. How can i resolved this problem?

Answer 1

There is no need to write <plug-in> in struts.xml for struts2 web application.

Struts 1 provides a plugin class that provides listener-like
capabilities.
The Struts 2 plugins are like Eclipse or FireFox plugins, and not at
all like Struts 1 "plugins".

A Struts 2 plugin is a single JAR that contains classes and
configuration that extend, replace, or add to existing Struts
framework functionality. A plugin can be installed by adding a JAR
file to the application’s class path, in addition to the JAR files to
fulfill whatever dependencies the plugin itself may have. To configure
the plugin, the JAR should contain a struts-plugin.xml file, which
follows the same format as an ordinary struts.xml file.
