Hi: I am embedding Jetty in Equinox and am struggling to get JSPs to work. Note, I am trying to implement this using the extension registry (e.g. plugin.xml). I have read a handful of threads on this topic but have had no luck tracking down the specific issue I have:
The JSP engine is able to receive my HTTP request, parse the parameters, etc., but it breaks at the point where it tries to initialize session objects for the page. The stack trace indicates there is no SessionManager, which obviously presents an issue. Am I incorrectly configuring the JspServlet / Equinox environment somehow, or is this potentially a Jetty-level issue (in which case I can redirect this question)? I have included the stack trace below and am happy to send over more context based on what would be helpful. I am new to the OSGi/Equinox world and would appreciate any pointers to help me uncover any unknown unknowns I may be dealing with. Thanks in advance, Vijay 11:13:41.346 [qtp11652231-28 - /alpha/index.jsp?foo=bar] DEBUG org.eclipse.jetty.util.log - REQUEST /alpha/index.jsp on
