Hi,
On a Ubunu 10.04 system (64 bits, 2.66Ghz Quadcore, 4GB RAM), one of my co-workers has huge problems with the JBoss tools RichFaces plugin (the JSP/JSF editor) on Eclipse 3.5.2 with JDK6u18.
Simply installing it causes a huge delay when starting Eclipse. After Eclipse has finally started, everything is really slow. With no JSP/JSF/XHTML files open in any editor, and only a java editor open, refactoring a simple method to change its name takes minutes and eventually crashes with either an out of heap space error or a GC exhausted error.
As soon as the JBoss tools RichFaces plug-in is de-installed, everything is fast again.
As a test we installed a clean new Eclipse EE edition, created a new workspace, installed nothing else besides the JBoss tool RichFaces plug-in, and via commandline HG cloned a Mercurial repository, from which we imported a project in Eclipse. Everything started to slow-down again.
Incidentally, a few other computers with a very similar software installation (also Ubuntu 10.04/64bits/Eclipse 3.5.2/JDK6u18) don't seem to have this problem.
Any idea?

[JBoss Microcontainer] - JBoss-classloading.xml in EAR /EJB

Hi ,
I have an EAR which I deploy in jboss-5.1.0.
A.EAR
|----lib/x.jar
|----EJB1.jar
|----EJB2.jar
I wanted to just expose the interfaces from the EJB's, hence I have jboss-classloading.xml in both EJB1.jar and EJB2.jar.
What I was hoping to achieve is that just have the interfaces exposed in my EJB's to other EJB's in the same EAR and also to other EAR's in AS.
EJB1.jar
|-----------com.ejb1.interface.EJB1Intf / EJB1IntfLocal extends EJB1Intf / EJB1IntfRemote extends EJB1Intf
|-----------com.ejb1.implementation.EJB1Bean implements EJB1IntfLocal,EJB1IntfRemote.
|-----------META-INF/jboss-classloading.xml
<classloading xmlns="urn:jboss:classloading:1.0" domain="A.EAR-0.0.1-SNAPSHOT-exploded.ear" parent-domain="DefaultDomain"
export-all="NON_EMPTY" import-all="true" excluded="META-INF">
<capabilities>
<package name="com.ejb1.interface" />
</capabilities>
</classloading>
Similarly for EJB2.jar.
This is how my jmx-console looks like:
h2. jboss.classloader
* http://localhost:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jb... domain="A.EAR-0.0.1-SNAPSHOT-exploded.ear",system=557851707
* http://localhost:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jb... id="vfsfile:/jboss-5.1.0.GA/server/default/deploy/AEAR-0.0.1-SNAPSHOT-exploded.ear/"
* http://localhost:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jb... id="vfszip:/jboss-5.1.0.GA/server/default/deploy/AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1.jar/"
EJB1 calls EJB2 via JNDI.
EJB1Bean:
public boolean callTheOtheEJB() {
EJB2Intf myStateless = lookup(EJB2Intf.class, "service/EJB2IntfBean");
logger.info("Called myStateless sayHello = "+ myStateless.sayHello());
return true;
}
EJB2Bean:
public String sayHello(){
return "Hello"
}
My Client:
Properties props = new Properties();
props.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(InitialContext.PROVIDER_URL, "jnp://127.0.0.1:1099");
try {
InitialContext jndiContext = new InitialContext(props);
Object obj = jndiContext.lookup("AEAR-0.0.1-SNAPSHOT-exploded/EJB1Bean/remote");
System.out.println(obj.getClass());
EJB1Intf callingEJBIntf = (EJB1Intf)obj;
callingEJBIntf.callTheOtheEJB();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Problem: EJB1 cant see EJB2Intf.
Caused by: java.lang.ClassNotFoundException: com.ejb2.interface.EJB2Intf from BaseClassLoader@1f9c621d{VFSClassLoaderPolicy@53ed6e21{name=vfszip:/jboss-5.1.0.GA/server/default/deploy/AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1.jar/ domain=ClassLoaderDomain(a)b901239{name=AEAR-0.0.1-SNAPSHOT-exploded.ear parentPolicy=BEFORE parent=ClassLoaderDomain@7a0aae8a{DefaultDomain}} roots=[DelegatingHandler(a)148464531[path=AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1.jar context=file:/jboss-5.1.0.GA/server/default/deploy/ real=file:/jboss-5.1.0.GA/server/default/deploy/AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1.jar]] delegates=null exported=[com.ejb1.interface]NON_EMPTY}}
They are part of the same ClassLoaderDomain.
When I do listExportingClassloader() for AEAR domain,
{com.ejb1.interface=[jboss.classloader:id="vfszip:/jboss-5.1.0.GA/server/default/deploy/
AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1-SNAPSHOT.jar/"],
com.ejb2.interface=[jboss.classloader:id="vfszip:/jboss-5.1.0.GA/server/default/deploy/
AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB2-SNAPSHOT.jar/"]}
Can anyone help? I am not sure where I am going wrong.

How did you fix it exactly? I'm having the same issues. There are no semicolons in the JVM_PARAM values above. I copied what is above and I am getting the following errors.
