1. Re: Help with error : Class X violates loader constraints
jasonbrome Feb 18, 2002 6:20 PM (in response to joao.clemente)Hi,
I'm experiencing this exception as well. Today I started to test with the v2.4.4 (Tomcat 4.0.1) release. I took my .ear that works perfectly with JBoss 2.4.4 / Tomcat 3.2.3, and am now experiencing issues with this new release.
It seems to be a Class Loader related issue - the class in my app that is reported as violating loader constraints is a Value Object class, an instance of which is returned from a Session Bean method. I've read elsewhere that there maybe potential packaging/scope issues related to this, and I was wondering if anybody has any guidelines?
Thanks,

joao.clemente Feb 20, 2002 8:28 AM (in response to joao.clemente)You mean that this may be a problem with the code itself? And not with the deployment?
I haven't still solved the issue I'm having and I think I'll try with the bundel with the older Tomcat version to see if it works there... -

jasonbrome Feb 20, 2002 10:52 AM (in response to joao.clemente)I'm not sure what is the cause of the problem, but it seems that there is a difference in class loading behavior between the Tomcat 3.2.3 package and the Tomcat 4.0.1 package - can anyone else shed any light on this?
Thanks

4. Re: Help with error : Class X violates loader constraints
joao.clemente Feb 25, 2002 1:54 PM (in response to joao.clemente)One other strange thing :
I've now reverted to using JBoss+Tomcat3.x , and with the app I was trying to deploy (that originated this thread) I don't get the error I was getting with Tomcat4 ...
However, one other app I was running fine in Tomcat4 doesn't deploy in tomcat3.x .. weird ...
I have looked a bit through Tomcat's homepage trying to find out if they had a report on diferences between the two versions but found nothing... -

cs710 Jul 20, 2002 5:10 PM (in response to joao.clemente)I had the same problem. Everything runs well on Solaris, but gets the problem on Linux. Any update?

6. Re: Help with error : Class X violates loader constraints
jkrause Aug 1, 2002 3:10 PM (in response to joao.clemente)I get the same error when I update a class in a EJB jar file then jar/upload it to the JBoss server. When debugging a problem, I have to frequenty upload the changed EJB jar files to the jboss server folder, overwriting the old ones then have the server auto-reload it. When my jsp tries to load the EJB again, I get this error. However if I kill JBoss server and restart it, not changing anything, the new classes load without error.
Its just annoying to have to reload JBoss every time I make a change to a EJB class in a Jar file. I used to not have to do that.
