Anyone got Sitemesh working on Tomcat?

Looking at some presentation options for Struts, the frontrunners being Tiles and SiteMesh.

I really like the idea of SiteMesh, even more so after playing with Tiles (which adds its own management problems into the equation with the requirement to edit tiles-defs.xml for each new page, and forcing you to author html fragments rather than real McKoy valid pages). Sitemesh look very elegant and ultra-low-maintence when adding new pages!

Unfortunately, though, I can’t Sitemesh to run under Tomcat (either 4.1.24 or 5.0.16). Both give the same deal:

org.apache.jasper.JasperException: getOutputStream() has already been called for this response

...

at com.opensymphony.module.sitemesh.filter.PageFilter.applyDecorator(PageFilter.java:169)

The readme makes noice about using jsp rather than html for page extensions, but even changing that just gives me..

org.apache.jasper.JasperException: Cannot call getWriter() after getOutputStream()

at the same line. The readme also notes that Sitemesh has issues on WebSphere, WebLogic, and other containers… so I may just be one of the unlucky ones.

Anyways, I’m not doing anything tricky, just autodeploying the sitemesh-example.war that comes with the package.

Anyone got it working on Tomcat? I’m playing with sitemesh-2.0.1.
