[Design of JBoss Web Services] - JAX-WS 2.1 and JBoss 4.2.2
by Marlboro
Hi,
I'm deploying our J2EE application with JAX-WS 2.1 on JBoss 4.2.2GA. Unfortunately I have suspition that JBoss and JAX-WS cause memory leaks because approximately after 24 hours with heavy load, JBoss crashes with OutOfMemory exception. And this happens when JAVA tries to allocate more than 2 GB of ram (Windows server 2003, 4 GB ram, 2x quad core Intel Xeon).
When I started my investigation, I used native memory profiler which showed that large memory is allocated from zip.dll. This is why I decided to take a look at class loader.
I found that in runtime a lot of classes are loaded by __JVM_DefineClass__ and org.jboss.mx.loading.UnifiedClassLoader3.
Below you can see how the number of loaded classes grows and also you can see classes which are loaded more than once. Also there is a link to screenshot from performance monitor with memory graphs http://www.3dspace.cz/perfmon.jpg.
JBoss started

[Design of JBoss IIOP on JBoss] - Configuration of Jboss with corba failed
by fatma
Hi all,
I am trying to configure the jboss server (4.2.0) to use corba instead of RMI.
So , I have done the following changes:
- I modify the file jndi.properties by adding the following lines:
java.naming.factory.initial=com.sun.jndi.cosnaming.CNCtxFactory
java.naming.provider.url=corbaloc::lidev206:5528/JBoss/Naming/root
and in the jboss.xml file I have included for each bean description the following entry:
<invoker-proxy-binding-name>iiop</invoker-proxy-binding-name>
But when starting the jboss server, I have the exception described below:
WARNING: "IOP00410201: (COMM_FAILURE) Connection failure: socketType: IIOP_CLEAR_TEXT; hostname: lidev206; port: 5528"
