Re: [jetty-users] JSP issue with embedded jetty
|
Susmit,
Does it work if you move the jsp out of WEB-INF and into a directory above it?

Hi,
I'm trying to test JSP tags that are defined as .tag files in my application's WebContent directory. The webproject layout is as follows:
Project
---WebContent
-------WEB-INF
-----------tags
--------------tag1.tag
---------- views
--------------tagTest.jsp
Using standalone jetty, I'm trying to load test jsp. tagTest.jsp is just a wrapper over the tagfile and invokes it using tagdir attribute like:
<%@ taglib prefix="test" tagdir="/WEB-INF/tags" %>
<test:tag1 model="${cat}" />
I have setup the server like this:
WebAppContext webCtx = new WebAppContext();
webCtx.setContextPath("/jsptest");
webCtx.setDescriptor("WebContent/WEB-INF/test-web.xml");
webCtx.setResourceBase("WebContent");
ContextHandlerCollection contexts = new ContextHandlerCollection();
contexts.setHandlers(new Handler[] { webCtx });
server.setHandler(contexts);
I have set up a servlet that forwards the request to test jsp since I was not able to invoke jsp from subdirectory of WebContent directly:
request.setAttribute("cat", new SomeModel());
getServletContext().getRequestDispatcher("/WEB-INF/views/tagTest.jsp").forward(request, response);
Invoking this servlet gives following error (also same error if I copy test jsp directly under WebContent and invoke as /jsptest/tagTest.jsp)

How to configure JSP with embedded jetty that have tagdir tags? Do I need to have a war if tagdir's are used?
P.S. Regular jsp is getting loaded fine, tag uri is getting resolved correctly:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %> - this works
Thanks,
Susmit
