JSP Precompile - Doesnt Work

Question

Hi All,
          I am having serious trouble trying to precompile my JSP's and have the wl
          server recognise them (and not re-compile them for me). Im using WLS6.1 with
          SP2 installed.
          I am running the JSPC pre-compiler with -D ....WEB-INF\classes. The files
          get created as expected and then I put them into my WAR file. When I deploy
          the WAR file, WLS always recompiles. I have experimented at length with
          different settings in my weblogic.xml, but as yet have had no success. I
          have also read some previous posts, but these have not helped either.
          Any suggestions or advice are very welcome!
          Thanks,
          Mark
          

Answer 1

          The suggestion to register JSPs as servlets is not at all practical or acceptable
          to me. Across multiple applications, we have over 200 JSP files and there's no way
          I would even consider this approach. What needs to happen is BEA should fix the problem
          and be more forthcoming about such "bugs" instead of letting the customers serve
          as QA and having to "ask" for patches. Why is 6.1 SP3 not on the web site? Why aren't
          all the patches available online for download? For the amount of money BEA charges,
          especially for clustered licenses, this type of problem should not go unfixed.
