[jboss-user] new webapp classloader problem. (I will update the wiki. I promise!)

[Bill Milbratz]

Hi all,

Sorry if this is a basic question, but I've gone through the documentation and various configuration options and still have a classloader issue when trying to deploy a new web-application alongside our .ear file . I wanted to check the list to "make very plain" what I need to do.

Here's the scenario:

* we use jboss 3.2.6 to deploy "ourapp.ear". 

* We wanted to deploy Sun's java directory editor webapp "de.war" alongside ourapp.ear, i.e. in the "deploy" directory

Here's the problem:

* "ourapp.ear" refers to struts 1.1. de.war refers to  struts 1.2 (one example of class version issues). Jboss gives classloader exceptions.

I have tried the following:

* added jboss-app.xml to ourapp.ear/META-INF directory 

* added jboss-web.xml to de.war's WEB-INF/ directory

* tried all four combinations of "JbossWebloader" and "Java2ClassloaderCompliance" in jboss-web-tomcat50.sar/META-INF/jboss-service.xml

* I've tried packing the de.war as an ear file and adding de.ear/META-INF/jboss-web.xml

I still get problems

Problem details:

* Either log4j classcast exception or  struts classcast exception depending on the values of JbossWebLoader and Java2ClassloaderCompliance

* Sun directory editor appears to misbehave if I browse to it before jboss has finished deploying all the references.

Question:

* I wanted to confirm: do I need to add jboss-web.xml to the de.war? 

* Is log4j a special problem? i.e. because jboss uses it itself?

* I got farther by removing the log4j and loggins-common.jar from the sun 'de.war', but this seems a hack.

* Does this sound right? what appears to be incorrect?

This problem is fairly well documented, but could use that extra bit of clarity. I will update the jboss wiki with your answer to make the problem idiot proof.

I welcome your suggestions. 

thanks
