jsp's are re-compiled after every tomcat restart? [message #88894]

Hi Simon,

as you know :), I'm running Equinox with Tomcat 5.5, and i noticed that
whenever I start my Tomcat, the compiled jsp's in my Tomcat working
directory are always deleted on startup and compiled again, when they got
loaded.
Is there a way to configure my HttpService or HttpContext, that my cached
(compiled) jsp's become reusable (Tomcat default behaviour)??

thx,
teos

Right now your compiled jsps are stored in a temp dir associated with the
HttpContext which as you've noticed is cleaned up alongside with the objects
lifecycle.
Part of this is to handle situations where we do want to recompile in
reaction to changed dependencies, however it's still worth thinking about
providing someway to parameterize behaviour -- maybe next release.

If this is causing you real grief then maybe consider pre-compiling your
jsps. This just works and is portable under any appserver when using the
servletbridge.

Yeah, such an option would be nice in a future release :)
A last question to this topic - when I have compiled jsp's from a last
tomcat run in my work-dir and I restart tomcat with changed bundles
(dependencies), than there shouldn't be any references to the compiled
jsp's - in this case, I could update my eclipse directory (before tomcat
start) in the work-dir and the already compiled jsp's could be reused - is
that so, if they're not removed automatically by the framework launcher??

thx,
teos

Hmm... I think you're asking about the lifecycle of the work-dir. Keep in
mind that each HttpContext is associated with its own context.temp.dir.
The intent is that your compiled JSPs should be removed along with this temp
dir whenever the associate HttpContext is no longer referenced by a servlet
or resource registration. This might occur if your bundle's dependencies are
changed however the most common case would be if the framework is shutdown.
In addition to regular lifecycle cleanup, to ensure everything from a
previous run was cleaned up properly the HttpService initialization code
will also remove any old HttpContext temp dirs that remain.
