Class ORBSingleton
java.lang.Object
org.omg.CORBA.ORB
org.omg.CORBA_2_3.ORB
org.jboss.system.ORBSingleton
public class ORBSingleton
- extends 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.
