[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: Classloader issues in JBoss 5.0.0

[Tarantul]

Thank you for this tip. Unfortunately the error is not resolved.

I removed the following lines out of the jboss-web.xml:
<class-loading>
  | 	<loader-repository>reportal.loader:loader=reportal.war
  | 		<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
  | 	</loader-repository>
  | </class-loading>

Then I have created the jboss-clasloading.xml with following content:
<?xml version="1.0" encoding="UTF-8"?>
  | 
  | <classloading xmlns="urn:jboss:classloading:1.0"
  |               name="reportal.war"
  |               domain="MyWar_Domain"
  |               export-all="NON_EMPTY"
  |               import-all="false">
  | </classloading>

Then I get the same error regarding a SAX parser:

After remowing the xercesImpl the application can be deployed, but then I get a runtime exception while using CollectionUtils.isNotEmpty(...).
It seems like the commons-collections.jar from JBoss is being used and that it is a version prior to 3.2, where this isNotEmpty-method had been introduced. The appropriate commons-collections-3.2.jar is in the WEB-INF/lib directory of my application. Anyway the application was previously running in Tomcat without any problems.

2009-06-15 16:52:22,136 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/reportal].[action]] (http-127.0.0.1-8080-4) Servlet.service() for servlet action threw exception
  | java.lang.NoSuchMethodError: org.apache.commons.collections.CollectionUtils.isNotEmpty(Ljava/util/Collection;)Z

Thats why I think, that the JBoss libs are still loaded before the application libs.


Am I doing something wrong or is there some other possibility?
