Philipp Leusmann commented on WW-3381:
--------------------------------------
One addition:
To keep serving static content from jars working, an additional mapping is
required:
<filter-mapping>
<filter-name>struts2-prepare</filter-name>
<url-pattern>/struts/*</url-pattern>
</filter-mapping>
> Suport for decorating static content
> ------------------------------------

> Key: WW-3381
> URL: https://issues.apache.org/jira/browse/WW-3381
> Project: Struts 2
> Issue Type: Improvement
> Components: Plugin - SiteMesh
> Affects Versions: 2.1.8
> Reporter: Philipp Leusmann
> Priority: Critical
> Fix For: Future

> Original Estimate: 8h

> In my case this issue is occuring when trying to decorate static content with
> sitemesh, but it generally is more an struts-core ActionMapper issue.
> I was trying to decorate plain html files using the sitemesh-plugin.
> I expected it to work using the empty-string action mapper, and thus added a
> link to /decorated_html/foo.html . The reslut was an error page since all the
> variables in the template could not be resolved, due to a missing action.
> If
> org.apache.struts2.dispatcher.mapper.DefaultActionMapper.dropExtension(String,
> ActionMapping) would not return null for any url containing a dot but no
> slash and no supported action-extension after it, it would have worked.
> By looking at the tests, I found that the returned null was expected
> behaviour introduced for WW-2163.
> I think to resolve this issue it would have been better to promote more
> sofisticated filter mappings in the web.xml to avoid the empty action side
> effects described in a previous comment.
> In my case it would be sufficient to use filter mappings
> <filter-mapping>
> <filter-name>struts2-prepare</filter-name>
> <url-pattern>*.action</url-pattern>
> </filter-mapping>
> <filter-mapping>
> <filter-name>struts2-prepare</filter-name>
> <url-pattern>decorated_html/*</url-pattern>
> </filter-mapping>
> <filter-mapping>
> <filter-name>sitemesh-struts</filter-name>
> <url-pattern>/*</url-pattern>
> </filter-mapping>
> <filter-mapping>
> <filter-name>struts2-execute</filter-name>
> <url-pattern>*.action</url-pattern>
> </filter-mapping>
> <filter-mapping>
> <filter-name>struts2-execute</filter-name>
> <url-pattern>/decorated_html/*</url-pattern>
> </filter-mapping>
