Christian,
I tried your implementation of EcsJSPElement (together with a JspPortlet
that gets its content from a JSP). All looks to be working allright, however
I see that the content of the JSP appears on top of my Jetspeed home page
and not in it's Portlet box. Also the JSP element that gets constructed
appears "empty"?
I'm not familiar with ECS. Do you have any idea what it is I am doing wrong?
Thanks,
Rogier
