Custom ClassLoader

[dec200378]

I want to write a custom ClassLoader to load the whole application (.war).
My configuration is:

jboss-services.xml
---------------------------------------




jboss-web.xml
--------------------------------------
<?xml version="1.0"?>
<jboss-web>
<class-loading>
<loader-repository>
com.july:loader=jboss-trial.war
</loader-repository>
</class-loading>
</jboss-web>


TrialClassLoader.java
-----------------------------------------
/*
* Created on Oct 23, 2006
*
*/
package com.july.jboss;

import java.net.URL;

import javax.management.MalformedObjectNameException;
import javax.management.ObjectName;

import org.jboss.mx.loading.ClassLoaderUtils;
import org.jboss.mx.loading.UnifiedClassLoader3;

/**
* @author Administrator
*
*/
public class TrialClassLoader extends UnifiedClassLoader3 implements ServiceMBean {

public TrialClassLoader() {
this(null);
System.out.println("TrialClassLoader.TrialClassLoader");
}

public TrialClassLoader(URL url) {
super(url);
System.out.println("TrialClassLoader.TrialClassLoader(" + url + ")");
}

/* (non-Javadoc)
* @see org.jboss.mx.loading.RepositoryClassLoader#getObjectName()
*/
public ObjectName getObjectName() throws MalformedObjectNameException {
System.out.println("TrialClassLoader.getObjectName");
return null;
}

/* (non-Javadoc)
* @see org.jboss.system.ServiceMBean#getName()
*/
public String getName() {
System.out.println("TrialClassLoader.getName");
return null;
}

/* (non-Javadoc)
* @see org.jboss.system.ServiceMBean#getState()
*/
public int getState() {
System.out.println("TrialClassLoader.getState");
return 0;
}

/* (non-Javadoc)
* @see org.jboss.system.ServiceMBean#getStateString()
*/
public String getStateString() {
System.out.println("TrialClassLoader.getStateString");
return null;
}

/* (non-Javadoc)
* @see org.jboss.system.ServiceMBean#jbossInternalLifecycle(java.lang.String)
*/
public void jbossInternalLifecycle(String arg0) throws Exception {
System.out.println("TrialClassLoader.jbossInternalLifecycle(" + arg0 + ")");
}

/* (non-Javadoc)
* @see org.jboss.system.Service#create()
*/
public void create() throws Exception {
System.out.println("TrialClassLoader.create");
}

/* (non-Javadoc)
* @see org.jboss.system.Service#start()
*/
public void start() throws Exception {
System.out.println("TrialClassLoader.start");
}

/* (non-Javadoc)
* @see org.jboss.system.Service#stop()
*/
public void stop() {
System.out.println("TrialClassLoader.stop");
}

/* (non-Javadoc)
* @see org.jboss.system.Service#destroy()
*/
public void destroy() {
System.out.println("TrialClassLoader.destroy");
}

/* (non-Javadoc)
* @see java.lang.ClassLoader#findClass(java.lang.String)
*/
protected Class findClass(String arg0) throws ClassNotFoundException {
System.out.println("TrialClassLoader.findClass(" + arg0 + ")");
return super.findClass(arg0);
}
}


-----------------------------------------------------
After server startup, com.july:loader=jboss-trial.war appears in jmx-console, but this classloader is never used.

Anyone help what is wrong?

JBoss creates a classloader for you, given the JMX ObjectName name. I'm not sure how you specify what sort of object it is, I believe that's something fixed by the deployer. Why do you need to customize it?

I have a similiar problem. I also want to load my war with a custom classloader. Have you solved the problem?
