Set a Servlet Temp Directory
It is important for JSP to define a temp directory suitable for managing itself. Such a directory will be used for converting the JSP source into a java file and then compiling it into a class. A sub directory in this temp directory will be automatically added by the JSP implementation for loading the compiled JSP classes.
context.setAttribute("javax.servlet.context.tempdir",scratchDir);Set a non-System Classloader
The JSP implementation will refuse to the System Classloader (per JSTL + JSP spec), this will wrap the system classloader in a simple URLClassLoader suitable for use by the JSP implementation.
// Set Classloader of Context to be sane (needed for JSTL)
// JSP requires a non-System classloader, this simply wraps the
// embedded System classloader in a way that makes it suitable
// for JSP to use
ClassLoader jspClassLoader = new URLClassLoader(new URL[0], this.getClass().getClassLoader());
context.setClassLoader(jspClassLoader);Jsp Servlet must be named "jsp"
The JspServlet must be named "jsp" (per JSP spec).
// Add JSP Servlet (must be named "jsp")
ServletHolder holderJsp = new ServletHolder("jsp",JspServlet.class);
holderJsp.setInitOrder(0);Default Servlet must exist
The JSP implementation relies on various Servlet Spec requirements, but mainly the fact that a "default" named servlet must exist.
// Add Default Servlet (must be named "default")
ServletHolder holderDefault = new ServletHolder("default",DefaultServlet.class);
holderDefault.setInitParameter("resourceBase",baseUri.toASCIIString());
holderDefault.setInitParameter("dirAllowed","true");
context.addServlet(holderDefault,"/");
