Is your Controller class extending TilesRequestProcessor or RequestProcessor?

I'm actually extending RequestProcessor. But your solutions sounds feasible. I'm go to try it afterwards.

What is still unclear to me is the fact that on our clustered test environment the problem has never been occured (unlike the production env).

Thanks for the great help! Have a nice day.

Hi
Thanks for your reply. Do you mean, that I have to change the controller definition in struts-config.xml? Actually this definition looks as follows:
<controllerprocessorClass="ch.admin.bit.edec.equota.web.CustomRequestProcessor" contentType="text/html; charset=ISO-8859-1" locale="false" nocache="true" />
We use a customized request processor which only overrides the method processRoles(...).

However, the TilesRequestProcessor isn't configured in struts-config.xml. I have already seen a struts-config.xml with the following controller-element:
<controller contentType="text/html; charset=ISO-8859-1"locale="false" nocache="true"/>
What is the consequence of a definition without specifing the class? This processor thing is confusing.

Thanks to throw light on this.

Hi all,
We have a webapplication based on struts which runs in a clustered environment. On one servernode we get an ugly Nullpointer that occurs in the RequestProcessor class. In the RequestProcessor the reference to the ActionServlet is null. This is quiet strange because the RequestProcessor is created and initialized by the ActionServlet itsself (checked the struts sources and found the call [request]processor.init(this, config); in the action servlet).

We also use Tiles which subclasses the RequestProcessor. Maybe this is useful to mention.

Could this be a replication problem?
Could anyone help me?

Thanks in advance. Regards
