They say its fixed.... Guess it will come out with the next release.
<p>However, the following program

<br>The idea of the org.omg.CORBA.ORBClass property is to specify the concreate
<br>implementation of the ORB this is done so that the JDK can enable other
ORBs
<br>implementations. So if you are using Visigenic you will have to set
it to
<br>something like:
<br>"com.visigenic.CORBA.ORB" or something like that.
<p>So when you do o = org,omg.CORBA.ORB.init(); "o" will be actually
an instance
<br>the visigenic ORB.
<p>The problem is that you are specifying the ORB to be the abstract class
provided
<br>by the JDK which is not a real implementation but just a superclass.
<p>If you just want to use the JDK ORB implementation you do not have to
specify
<br>this property, the default should pick up the right thing.
<p>Hope it helps,
