WebSphere 6.0 Sitemesh plugin issue

[Ed Knutson <EK...@laughlin.com>]

I am building an application using Struts 2.0.8 on a WebSphere 6.0.2.17 ND server.  Another application on this server uses Webwork 2.2 with Spring and Sitemesh 2.3 and I was hoping the transition to Struts 2 would be relatively smooth.  This app server uses the 1.4.2 JVM and I am using the j4 binaries.

I ran the Spring and Sitemesh plugin jars through retrotranslator.  The logs show the overall system initializing properly, including Spring integration.  However, I get the following error when trying to access a page:


SRVE0026E:
[Servlet Error]-[Filter [sitemesh]: Could not find required filter class - org.apache.struts2.sitemesh.TemplatePageFilter.class]:
java.lang.ClassNotFoundException: class org.apache.struts2.sitemesh.TemplatePageFilter :

This file is indeed in the retrotranslated jar which was placed in WEB-INF/lib.  I also tried unjarring into WEB-INF/classes, as well as commenting out the single @Inject annotation in the source for this class and compiling it using JDK 1.4.  In all cases I get the same ClassNotFoundException.  For now, I replaced this section in the web.xml:

<filter>
    <filter-name>sitemesh</filter-name>
    <filter-class>org.apache.struts2.sitemesh.TemplatePageFilter</filter-class>
</filter>

with this:

<filter>
    <filter-name>sitemesh</filter-name>
    <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
</filter>


The pages then load correctly.  However, my understanding is that I won't be able to access the Struts 2 context from the decorator files if I don't use the plugin.  Has anyone else had this issue, or been able to run Struts 2 + Sitemesh on WebSphere 6.0?
