ClasscastException while deploying in JBoss 5.1

sanintel3 Feb 4, 2011 3:15 AM

I am getting below error while deploying the application in JBOSS 5.1.

1) caused by: Caught exception while loading file struts-default.xml - [unknown location]

at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.loadConfigurationFiles(XmlConfigurationProvider.java:894)

My application war containing

xalan-2.7.0.jar

xercesImpl-2.8.1.jar

xml-apis-2.9.1.jar

xmlbeans-2.3.0.jar

xmlParserAPIs-2.6.0.jar

XmlSchema-1.4.2.jar etc...

The same application works fine in tomcat and JBOSS 4.2.3, but it's not working with 5.1 If I ship jboss-web.xml with below content in war, it's working fine.

<?xml version='1.0' encoding='UTF-8' ?>

<!DOCTYPE jboss-web

PUBLIC "-//JBoss//DTD Web Application 2.3V2//EN"

"http://www.jboss.org/j2ee/dtd/jboss-web_3_2.dtd">

<jboss-web>

<class-loading java2ClassLoadingCompliance='true'>

<loader-repository>com.loader:loader=service-web

<loader-repository-config>java2ParentDelegation=true</loader-repository-config>

</loader-repository>

</class-loading>

<security-domain>java:/jaas/cdf-ldap</security-domain>

</jboss-web>

Or else even if I don't use Unified class loader(isolated loader for each webapp) by commenting out below configuration in war-deployers-jboss-beans.xml file, it works fine.

<property name="filteredPackages">javax.servlet,org.apache.commons.logging</property>

</bean>

which means if I use jboss classloader it works or else with UCL by enabling java2ParentDelegation to true, it's working.

As per my understanding if java2ParentDelegation=true, classloader tries to load the class from parent class repository(domain) cache first, if not it follows the normal hierarchy(of java2ParentDelegation = false configuration). What really makes difference by enabling this configuration while loading the xlan,xrecesImpl jars(which are also part of JBOSS lib)?

Also why it is working in JBOSS 4.2.3 with isolated class loader configuration and not working in 5.1 with same configuration? Will relative Order play any role here? I tried with -1,0,1 options, it doen't make any difference, getting the exception.
