Creating files dynamically and antiJarLocking

Hi all,
 
In my web project, I dynamically create JSP files in some ocasions.
These files are placed under my web application folder and only works
well if I don't use antiJarLocking='true' and
antiResourcesLocking='true'. In this case, my files are created
correctely, but I just can't reach them using their URLs. Tomcat returns
me a 404 error, just like if my pages weren't placed there. I know that
when we use antiJarLocking and antiResourcesLocking, all my war files
are unpacked under temp folder, and I suppose I should place my
dynamically created files there too right? Am I right? The only problem
is, Tomcat seems to create temp directories using a sequential number
preceding the folder name... Do I have acces to the most recent created
tempo directory?
 
thanks in advance,
 
Marcus Milanez

Absolutely. In my dev environment I'm constantly dropping new
JSPs in, and they show up fine. If that weren't true, I'd never get
/anything/ done :-)

But the default certainly allows it, or more people would be having
this same problem, I suspect...

Perhaps the OP can test with a simple JSP using a fresh install?

Jsps are recompiled when modified, and are compiled on the first
access. Thus I do not see why they cannot appear randomly.

I do not remember whether it is a part of the standard, but it is a
feature, and it supposedly can be turned off by some options.


What Tomcat version is Marcus using?

As for the path to the temp folder:
what is the result of calling ServletContext.getRealPath(...)?

This is likely because Tomcat expects all the resources for a web app to
be available at deployment time, rather than randomly appearing during
the life of the deployed webapp.

I believe similar questions have been raised in the past, the the answer
has been "don't do that". I'm not sure if there's a good way to achieve
what you're trying to do.
