JSP script parsing [message #219709]

When a JSP document is parsed, is anything done with JSP scripts (i.e.
scriptlets, declarations, expressions (non-EL) etc.) other than
partitioning them? Is any effort made to parse the script or provide
design-time support for it?

Thanks,

Cameron

Yes, an on-the-fly translation is done by the JSP model to build
source resembling the Servlet that a JSP container would create, and
then run through the JDT compiler for problem reporting. The
translation contains information on the bidirectional mappings
between scripting areas in the JSP file and the generated Servlet
source that's used for a number of functions in the source editor.
You'll have to give a little more details on what you mean by
design-time support, though, for more concrete answers.
