Struts 7 Migration Issues

Hi Guys,

We are moving forward with our plans to migrate from Struts6/Tomcat9 to=20
Struts7/Tomcat11 but we've hit a few snags I was hoping someone else has=20
experienced and hopefully solved.

The first and biggest issue is with Tomcat 11. The app runs as expected=20
but no pages are rendered and by that I mean nothing at all. Our logs=20
don't show any errors - we are using log4j2 with DEBUG as the ROOT level=20
default. The strange thing is when we run the same app on Tomcat 10.1.45=20
it works as expected, except for one possibly related issue.

We are using struts 7.0.3 with Tomcat 11.0.10 and Sitemesh 3.2.2 as our=20
decorator, we also tried Sitemesh 3.2.1 which made no difference.

Web.xml is configured as below:

<filter-mapping>
 =C2=A0 =C2=A0 =C2=A0 =C2=A0 <filter-name>struts-prepare</filter-name>
 =C2=A0 =C2=A0 =C2=A0 =C2=A0 <url-pattern>/*</url-pattern>
 =C2=A0 =C2=A0 </filter-mapping>

 =C2=A0 =C2=A0 <filter-mapping>
 =C2=A0 =C2=A0 =C2=A0 =C2=A0 <filter-name>sitemesh</filter-name>
 =C2=A0 =C2=A0 =C2=A0 =C2=A0 <url-pattern>/*</url-pattern>
 =C2=A0 =C2=A0 </filter-mapping>

 =C2=A0 =C2=A0 <filter-mapping>
 =C2=A0 =C2=A0 =C2=A0 =C2=A0 <filter-name>struts-execute</filter-name>
 =C2=A0 =C2=A0 =C2=A0 =C2=A0 <url-pattern>/*</url-pattern>
 =C2=A0 =C2=A0 </filter-mapping>

This is the critical issue as we want to identify the cause of the issue=20
and resolve rather than put it off.


The second issue is related to sitemesh, which the first issue may also=20
be. When we run the app on Tomcat 10 struts actions aren't identified in=20
the path attribute only the resulting jsp is. Let me explain, say we=20
have a test action configured in my struts.xml as such:

<action name=3D"testAction" class=3D"testActionClass" method=3D"test">
 =C2=A0 =C2=A0 =C2=A0<result>/WEB-INF/pages/testPage.jsp</result>
</action>

If I configure sitemesh like this:

<mapping decorator=3D"mainDecorator.jsp"/>
<mapping path=3D"*/testAction.action" decorator=3D"testDecorator.jsp"/>

The result is incorrectly decorated using the default mainDecorator,=20
this works correctly in our struts 6 setup which is more or less=20
identical, but if I change it to this:

<mapping decorator=3D"mainDecorator.jsp"/>
<mapping path=3D"*/testPage.jsp" decorator=3D"testDecorator.jsp"/>

The page is decorated correctly. As you can imagine that's not what we=20
want. Mapping to the actions is a far more elegant and manageable.

The documentation for sitemesh is a bit thin on their site so any=20
assistance would be appreciated.
