oh, one last thing.
i think it would be nicer if embedded pages can extend panels. i'm not sure if
it is possible (so when including a url, the panel class will be called)

ok, this is what i did given the existing wicket code. i'm sure it can
be done better by changing the code itself
1. change newWebRequest in QrmApplication
protected WebRequest newWebRequest(final HttpServletRequest
servletRequest) {
if (servletRequest.getPathInfo() == null) {
if
(servletRequest.getAttribute("javax.servlet.include.request_uri") !=
null) {
return new IncludedServletWebRequest(servletRequest);
}
if
(servletRequest.getAttribute("javax.servlet.forward.request_uri") !=
null) {
return new ForwardedServletWebRequest(servletRequest);
}
log.error("Could not find an implementation of WebRequest
that fits this request. trying the default");
}
return super.newWebRequest(servletRequest);
}
2. create IncludedServletWebRequest and ForwardedServletWebRequest. they
extend BaseServletWebRequest
for IncludedServletWebRequest:
public String getPath() {
return
(String)getHttpServletRequest().getAttribute("javax.servlet.include.path_info");
}
public String getContextPath() {
return
(String)getHttpServletRequest().getAttribute("javax.servlet.include.context_path");
}
public String getServletPath() {
return
(String)getHttpServletRequest().getAttribute("javax.servlet.include.servlet_path");
}
3. create BaseServletWebRequest, extending ServletWebRequest and rewrite
getRelativeURL
public String getRelativeURL() {
/**
* Servlet 2.3 specification :
* * Servlet Path: The path section that directly
corresponds to the
* mapping which activated this request. This path starts with a
"/"
* character except in the case where the request is matched
with the
* "/*" pattern, in which case it is the empty string.
* * PathInfo: The part of the request path that is not
part of the
* Context Path or the Servlet Path. It is either null if there
is no
* extra path, or is a string with a leading "/".
*/
String url = getServletPath();
final String pathInfo = getPath();
if (pathInfo != null)
{
url += pathInfo;
}
final String queryString =
getHttpServletRequest().getQueryString();
if (queryString != null)
{
url += ("?" + queryString);
}
// If url is non-empty it has to start with '/', which we should
lose
if (!url.equals(""))
{
// Remove leading '/'
url = url.substring(1);
}
return url;
}
4. if using a form create an EmbeddedForm class, and override the
onComponentTag
here i can't give a generic code, but the basic thing is to rewrite the
action, tag, so it goes to the original page, and put the action as a
parameter in the url, which is used by the containing page to include
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
String action = tag.getAttributes().getString("action");
Map parameters = new HashMap(getRequest().getParameterMap());
parameters.put("wicketAction", action);
String newAction = containingUrl +
StringUtils.toString(parameters, "&", null);
tag.put("action", newAction);
}
in the jsp, the code should be something like
<jsp:include page="<%=request.getParameter("wicketAction") == null ?
"url-to-wicket" : request.getParameter("wicketAction") %>"/>
hope it helps,

i've done some work to enable embedding wicket pages in jsp pages.
this is required by us, since we're currently using struts, and can't
move all our code to wicket. i think it is important to enable
existing projects to start using wicket.
the main problems in that HttpServletRequest.getPath() returns null
for forwarded/included pages
i can submit the code if you want
