The postings below pointed to the two most promising approaches:
- Either take your servlets code and pack it into a portlet or
- using the EcsServletElement to include the output of a servlet within a
portlet (see earlier postings about this topic).
(Note that the latter way is very easy, but it is generally bad practise to
open HTTP connections from within a servlet container to a servlet in the
same container. In systems under high load, the EcsServletElement sould
only be used with remote servlets.)
