Error handling when exception occured

[jhomuth]

Hi List,

I've successfully created an error page when an http error (e g. 404) 
occurs. But when an exception will be raised, I only see the standard 
myFaces error page. Do I miss something in the web.xml definitions.

Here my web.xml error page definitions

<!-- Pages that will be displayed in case of an specific error -->

   <error-page>
       <exception-type>java.lang.Throwable</exception-type>
       <location>/aisdcl/pages/general/errorpages/exception.jsp</location>
   </error-page>

   <error-page>
       <error-code>404</error-code>
       <location>/aisdcl/pages/general/errorpages/404.jsp</location>
   </error-page>

Do I have to insert a context param which defines an alternate error 
handler or miss I something in here.

I've tried to produce an exception in my controller by this way.

/**
    * This method is for test purposes only. It has no useful content 
and will
    * always fail with an Nullpointerexception
    * @return
    */
   public String getTest(){
       Object fakeObj= null;
       return fakeObj.toString();
   }

As I said above, the standard myfaces error page will displayed not my own.

Thx for suggestions

Hannes
