help problem with extending dwrServlet

[robyp]

hi

i try to extends servlet and invoking it in web.xml but when the browser page opens it says (dbug with firebug utility) that dwr in javascript is not definited..
and give me this error:

GRAVE: Error loading WebappClassLoader

        at java.lang.Thread.run(Thread.java:619)


the only things i do are:

public class Initiate extends DwrServlet implements ScriptSessionListener{
..

//i override only this method
@Override
    public void init(ServletConfig servletConfig) throws ServletException {
        super.init(servletConfig);
        System.out.println("- ** DWR Servelet initialization completed, add listener now");
        //register DWR Session Listener after servelt initialization
        d = new DWRWebContextWrapper(WebContextFactory.get());
        Container container = d.getWebContext().getContainer();

        ScriptSessionManager manager = container.getBean(ScriptSessionManager.class);
        System.out.println(manager);
        manager.addScriptSessionListener(this);
    }
...
..

and web.xml:

<servlet>
        <servlet-name>dwr-invoker</servlet-name>
        <!-- replaced with my servlet-->
        <!-- org.directwebremoting.servlet.DwrServlet-->
        <servlet-class>it.netbureau.DwrSessionspike.Initiate</servlet-class>
        <init-param>
            <param-name>debug</param-name>
            <param-value>true</param-value>
        </init-param>
        <init-param>
            <description>enable/disable Comet(reverse ajax) </description>
            <param-name>activeReverseAjaxEnabled</param-name>

        </init-param>
        <init-param>
            <param-name>maxWaitAfterWrite</param-name>
            <param-value>-1</param-value>
        </init-param>
</servlet>
<servlet-mapping>
        <servlet-name>dwr-invoker</servlet-name>
        <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>

dwr 3.0 rc1 is a jar(.class files) in the lib folder of my project and the classes are under /build/classes folder (instead of src: /scr/java) like netbeans 6.7 do..
i wouldn't to include all dwr source and modify dwr code.....

Init was not called, why?

thank you

It looks to me like you haven't deployed your class to tomcat.

hi,
uhm
this is strange..in netbeans i do:
Clean and build and then deploy:
(with org.webremoting.servlet.DwrServlet work fine..)
i try also take compile classes from package it and copy it in dwr.jar but nothing changes..
any suggestion?

thank you
