Andrew, The server stores the source filename, path, and line number information into the SMAP when it translates the jsp/gsp into Servlet source and compiles the .class file. JDT and our plug-ins aren't involved with this part. The debugger doesn't actually need the .class files since the JDI stack frame communicates the class' source filename and path information based on the SMAP. When it comes to the path value, however, we're at the mercy of the server's translation engine as the path is underspecified in the JSR (see bug 99674 for the gory details). The launch's source lookup director will still try to find the right file in the launch's projects based on this information.
Basically I think your biggest concern will actually be setting and clearing Java Stratum breakpoints with class values that "hit" consistently and path values that work for the source lookup. Being able to use the Display/Execute/Inspect abilities that are available in the Java editor would be fantastic, but we haven't explored those features ourselves, yet.

GSPs already have an SMAP set up properly. The only tricky part (I think) is telling the debugger where to find the line number information. How does the debugger know where to find the .class files for a jsp file? They are compiled at runtime, are they not?
