Guys,
Many thanks for your time.
Finally it works the way I described initially ... I feel a bit confused.
It seems there is no way to do that a more simple way without using JSP 2.0.
One day we will move to 2.0 and I will change that.
Denis.
Hello Marc,
That seems great but I think we won't use JSP 2.0 cos we need Jetty
Stable release.
Somebody told me about commons-jexl.... maybe this would be the best
solution.
Thanks for your help.
Denis.

What about using directly a
org.apache.commons.el.ExpressionEvaluatorImpl? No PageContext is needed.
You just have to provide a javax.servlet.jsp.el.VariableResolver and
I think you should write it carefully to avoid generating a security
hole as your EL comes from the request.

Hi,
The idea is an hyperlink on HTML Page calling a Struts Action
and with an URI ending with like
myAction.do?elexpression="sessionScope['mylist'][param.row]"
So I need the ELanguage power in my Action.execute( ) method.
I tryed to get a PageContext( ) from JSPFactory.DefaultFactory( )
(using current request, response,etc )
but now my container (Jetty) send JSP source instead of JSP
processing result.
--------------------------
public class DetailHandlerAction extends Action {
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
PageContext pc =
JspFactory.getDefaultFactory().getPageContext(this.getServlet(),request,
response, null, true, 4096 , false );
evaluatedDetailRef = ExpressionEvaluatorManager.evaluate(null,
detailRef, Object.class, pc);
javax.servlet.jsp.JspFactory.getDefaultFactory().releasePageContext(pc);
----------------------------
Any idea ?
Thanks for your help.
Denis.
