Thanks for the reply. I'll take a look at the patches/taglib. I still don't see my Screen classes executed though, unless I modify, or override, JspLayout::doBuild() to exec the screen (Note: This solution has other problems.). I think my problem may be that I am not using the "screen_placeholder" object correctly.
Does anyone have an example of how to use "screen_placeholder"? The JavaDoc of JspScreenPlaceholder says to declare it as a bean, and use "<%=screen_placeholder%>", but this just puts the Object.toString() output on the page. The only other method in JspScreenPlaceholder is exec(), which looks like it would execute the JSP, but I don't see how to get the generated HTML to output to the response. An example of how to use the "navigation" object (of type JspNavigation), which is also in the request, would be appreciated also.
TIA, Joe

Joe, I use JSP for templates and use Screens. They do get called. I was in the same situation you are--even though I prefer Velocity I had to use JSP. Therefore, I added new features to enhance JSP support in Turbine, making it support Context to pass data around and ActionEvents. I posted this patch on the turbine-dev list.
