org.jboss.system
Class ORBSingleton

java.lang.Object
  extended byorg.omg.CORBA.ORB
      extended byorg.omg.CORBA_2_3.ORB
          extended byorg.jboss.system.ORBSingleton
public class ORBSingleton
extends org.omg.CORBA_2_3.ORB

Thin wrapper class that fulfills the contract of an ORB singleton and forwards every invocation to an instance of the actual ORB singleton class, which it loads with the context classloader. The name of the actual ORB singleton class is specified by the system property org.jboss.ORBSingletonDelegate.

This class is a workaround to the the following problem: unlike the Sun VMs, IBM VMs do not use the context classloader to load the ORB singleton class specified by the system property org.omg.CORBA.ORBSingletonClass. IBM VMs use the system classloader, thus requiring the ORB singleton class to be in the system classpath. Rather than adding a third-party jar file (e.g. jacorb.jar) to the system classpath, we include this class in run.jar. Instead of setting the system property 

     org.omg.CORBA.ORBSingletonClass=some.orb.impl.ORBSingletonImpl
we set two properties: 
     org.omg.CORBA.ORBSingletonClass=org.jboss.system.ORBSingleton
     org.jboss.ORBSingletonDelegate=some.orb.impl.ORBSingletonImpl

This class should be removed when IBM fixes its VMs.

Field Summary
static java.lang.String DELEGATE_CLASS_KEY
          System property key that specifies the actual ORB singleton class.
 
Constructor Summary
ORBSingleton()
          The ORBSingleton constructor does what the IBM VM does not do: it uses the context classloader to load the actual ORB singleton class.
