strange post deploy errors! HELP!

[kburn]

hi fellas,
I'm developing an application based on java beans+jsp over an oracle DB on jboss-3.2.5 ..
I'm writing all tha stuff via JBuilder2005[update1] and it happens very often that, when I deploy a WAR, jboss comes out with strange and ununderstandable errors..
I discovered that this kind of trouble is jboss's caching fault..
but every time it's a bit different from the other one..
e.g. one day I made a deploy and I found that by erasing all tha $JBOSS_HOME/server/default/tmp/deploy, the $JBOSS_HOME/server/default/deploy/mywar.war, rebuild my webmodule and deploy it again it worked, but not all the times this tecnique works..

so my question is:

W H Y does jboss behaves like this???
and
W H A T can I do to patch this problem?? cuz,managing those troubles takles me more time than writing&debugging my code..

I hope I made my self clear :P

tya 4 any suggest, greetz

You forgot to tell us what the problem is.

jboss comes out with strange and ununderstandable errors

Post the errors here, others may not find them so strange and ununderstandable.

that's tha last err I'm dealing whith..

I deployed my app it was all ok,
then I saw an error in the Javascript (so nothing that has to do whith
java or jboss) and after the redeploy that's what jboss told me:

Have you included any of the servlet API in the war file that you are deploying?

[kburn]

dunno,
but I tell u this:

if I made a deploy that's working fine, and then I simply change a row of javascript code, this should'n affect the redeploying in any sense.. :S isn't' it?
:(

[kburn]

by the way, I solved this problem by erasing all tha wars in the deploy directory, all the stuff in the tmp/deploy and by restarting jboss ..

but that's insane!

this problem is taking me 2 much time, all the times

[darranl]

dunno,

Well find out.
