Background:
We are wanting to add a capability to our webapp which requires that we be able to reference precompiled jsp's from multiple jars discovered at the time the webapp starts. Currently, we precompile all our core jsp's into a jar, and get that to work by making sure the jar is in the codebase for tomcat, and including a snippet (generated at build time) into web.xml that looks like a series of these:
<servlet> <servlet-name>com.tripwire.jsp.index_jsp</servlet-name> <servlet-class>com.tripwire.jsp.index_jsp</servlet-class> </servlet>
One per compiled jsp. That is fine for our core jsp's which can be mapped statically like this. But as I said, now were adding the ability to add plugins into our webapp, which can contain their own UI elements in the form of jsp's.
Requirement:
What I need is a way to dynamically add the mappings to tomcat while the webapp starts. I have poked around in the code and discovered JspRuntimeContext.addWrapper() which looks like what I'd want to use to dynamically map the jsp's as our webapp starts up -- assuming I can discover the mappings, which I will be able to. What I am not clear on is precisely how to use this functionality, which appears to be somewhat internal to tomcat, from my webapp -- i.e. would I need to override JspServlet with my own?
