java.lang.ClassNotFoundException: No ClassLoaders found erro
I am a new remoting user and I am having trouble getting started with it. I am using the version of remoting that ships with JBoss_4_0_1_SP1 date=200502160314. Because there is a lot of text related to the service xml and exceptions here, I have numbered my comments so you can follow them.
1. I am using the following remoting-service.xml under server/all/deploy:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE server>
<!-- ======================================================== -->
<!-- Example JBoss Remoting Service Configuration file -->
<!-- ======================================================== -->
<server>
<!-- NOTE: set this up to the path where your libraries are -->
<classpath codebase="lib"
archives="*"/>
<mbean code="org.jboss.remoting.network.NetworkRegistry"
name="jboss.remoting:service=NetworkRegistry"/>
<mbean code="org.jboss.remoting.transport.Connector"
xmbean-dd="org/jboss/remoting/transport/Connector.xml"
name="jboss.remoting:service=Connector,transport=Socket"
display-name="Socket transport Connector">
<attribute name="InvokerLocator">socket://${jboss.bind.address}:8084</attribute>
<!-- Uncomment when JMXSubsystemInvocationHandler is finished -->
<attribute name="Configuration">

</mbean>

<mbean code="org.jboss.remoting.detection.multicast.MulticastDetector"
name="jboss.remoting:service=Detector,transport=multicast">
<!-- you can specifically bind the detector to a specific IP address here
<attribute name="BindAddress">${jboss.bind.address}</attribute>

<mbean code="org.jboss.remoting.ClientInvokerAdapter"
xmbean-dd="org/jboss/remoting/ClientInvokerAdapter.xml"

</mbean>
</server>
2. The only thing I have done that is different from the default file is that I have uncommented the following lines:
<attribute name="Configuration"> <handlers> <handler subsystem="JMX">org.jboss.mx.remoting.JMXSubsystemInvocationHandler</handler> </handlers> </attribute>
3. I always getting the following exception:

4. This happens even when I try to create a simple invoker locator and handler as described in the famous ONJava article on Remoting as well as the Remoting User Guide.
Please help!
Thanks,
Alan
