embedding Wicket into JSP
Hi,
I have problem embedding Wicket pages (1.3.4) into JSP application.
index.jsp
<jsp:include page="/wic/ flush="true"/>
and the cause is that inside WicketFilter
public String getRelativePath(HttpServletRequest request) returns empty
string because the request returns path for the index.jsp and not the /wic/
so the doGet method tries to do redirect which does not succeed.
So the question: is it possible at all to embed Wicket into JSP pages?

Hi,
If you want _one_ Wicket Application appear within a JSP based page just
override getRelativePath() in WicketFilter to get the include-uri instead
of the request-uri:
String requestURI = (String) request.getAttribute(
"javax.servlet.include.request_uri");
if (requestURI == null) {
requestURI = request.getRequestURI();
}
String path = Strings.stripJSessionId(requestURI);
...
You'll maybe need you own RequestEncodingStrategy to combine you JSP base
URL and the wicket part, depending on your URL scheme.
If you want to embed different Wicket pages of one application on
_multiple_ locations of one JSP base page, you'll have to do more work:
You need to track the state of every wicket page to remember it when the
JSP page is rendered again. Here's how we've done this:
1. In the JSP create an id for the wicket application you want to render
at this location. We used the id of the CMS object (CoreMedia) for this.
2. Do the jsp:include
3. Override onAfterRender in your base page to track the rendered wicket
page at this location (getNumericId + getCurrentVersionNumber) for the id
generated in the including JSP
4. When the JSP is rendered again, the including JSP passes the last
tracked state to the Wicket pages. If a Wicket component was clicked, you
pass the actual request parameters to the Wicket application that rendered
that page (you've tracked this in step 3).
For bookmarkable pages some more effort is needed, but the post is already
long enough.

I have read that many times. That describes the opposite to the thing I need.
And it seems that W 1.3.4 code just plain make it impossible to embed W in
JSP. Am I reading W code wrong?
