Hi all,
I am frustrated that if I precompile my jsps on a BEA WebLogic the resulting war will not run on tomcat and the other way around.
From what I could figure out, each jsp compiler is "optimizing" by leveraging some propriatery classes that make the generated servlets run only on that servlet engine (or with their jars).
Is there some "standard" javax.servlet.* (no propriatery classes) compiler or even better source converter out there I could use that would not require any third party jar files in order to run on any app server.
Thanks in advance,
Guy.

Well, the problem is that I am shipping my application and I don't want my JSPs to be readable.
I know people may decompile, but that makes their life a little more complicated.
Also, since jsp can be directly translated to a servlet (i.e. javax.servlet.*) then there has to be a "clean" convertor or compiler out there (or at least I hope :().

Sorry it's not going to happen, they will always be readable.

You're correct. Precompiling is no real barrier to reading the jsp. To really obsfucate the java, you would need to load your own classpath with dynamically loaded servlets that would be checked against a Hash value with somehting like cryptix to encrypt them.
Ant is a platform independent pre-compiler but as I mentioned eariler, the JSP specs allow the vendors to do this is a proprietry manner so you cannot do it

How are you pre-compiling them? Are you using Ant?
I have a nasty feeling that while major application servers support pre-compilation of JSPs, they do so in a proprietry manner (http://www.javaworld.com/
You could also write a bot that could go through your site and request the JSPs with the precompilation parameter "example.jsp?jsp_precompil
