Intermittent deployment problems with Drools.

[toby.tobias.hill.gmail.com]

Every second or third deployment we get the stack
trace below indicating some linkage problem with
drools.

We use Seam 2.0.0.GA code on jboss-4.2.2.GA.

Anyone recognizing this problem who can point me in
a good direction.

Best regards,
Tobias

I guess you have some stale drools jar lying around

[toby.tobias.hill.gmail.com]

You are probably right. An ant target with:

  <delete dir="${jboss.home}/server/default/tmp"/>
  <delete dir="${jboss.home}/server/default/work"/>
  <delete dir="${jboss.home}/server/default/log"/>

... which is set to run on before run of JBoss in my IDEA seems to solve it for me. Or at least I haven't seen the problems since.

[toby.tobias.hill.gmail.com]

I was wrong. We still get these stack traces at deploy even though all directories tmp, work and log (FWIW) are emptied before deploy.

Anyone else seen this stack trace?

[damianharvey.damianharvey.gmail.com]

We're seeing a similar thing, in that every couple of days out Rules (used for pricing) start failing with compilation errors even though they haven't been changed.

eg Caused by: org.mvel.CompileException: unable to resolve property

Redeploying or restarting solves it.

Tobias, did you ever resolve your issue?

Cheers,

Damian.

Actually, we do not see these problems anymore. Unfortunately I don't know how we got rid of it. A lot has happened in our application since I wrote this. Possibly it could be the fact that I always clear the jboss directories as part of the build-process, but well ... I am not sure.
