CORBA under JBoss

[Janos Mozes]

Hello,
i wrote a small Corba-Client program. It works great. But i have a problem with the same code under JBoss. When i call the resolve method of the org.omg.CosNaming.NamingContext, i get the following exception:

java.lang.UnsupportedOperationException
at com.sun.corba.se.internal.ior.FreezableList.add(FreezableList.java:96)
at com.sun.corba.se.internal.core.IOR.<init>(IOR.java:239)
at com.sun.corba.se.internal.iiop.CDRInputStream_1_0.read_Object(CDRInputStream_1_0.java:652)
at com.sun.corba.se.internal.iiop.CDRInputStream_1_0.read_Object(CDRInputStream_1_0.java:641)

at org.omg.CORBA.ObjectHelper.read(ObjectHelper.java:59)
at org.omg.CosNaming._NamingContextStub.resolve(_NamingContextStub.java:245)

Do you know, what the problem is?
Thanks in advance,
J
