How do you get an embedded Jetty webserver to dump its interim Java code for JSPs

Question

I keep running into this problem when debugging JSP pages in OpenNMS. The Jetty wiki talks about keepGenerated (http://docs.codehaus.org/display/JETTY/KeepGenerated) in webdefault.xml but it seems unclear how this works in embedded setups.

Answer 1

It is dumped already. for example if you have a file called index.jsp, a file will be created called index_jsp.java Just search for something like that in the work directory.

Answer 2

If you are using Jetty 6 you can use the following code:

String webApp = "./web/myapp"; // Location of the jsp files
String contextPath = "/myapp";
WebAppContext webAppContext = new WebAppContext(webApp, contextPath); 
ServletHandler servletHandler = webAppContext.getServletHandler();
ServletHolder holder = new ServletHolder(JspServlet.class);
servletHandler.addServletWithMapping(holder, "*.jsp");
holder.setInitOrder(0);
holder.setInitParameter("compiler", "modern");
holder.setInitParameter("fork", "false");

File dir = new File("./web/compiled/" + webApp);
dir.mkdirs();
holder.setInitParameter("scratchdir", dir.getAbsolutePath());
