Accessing CORBA Object from EJB

[Roger L. Cauvin]

I have been unable to access a (Orbix) CORBA object from my (JRun 3.0)
stateful session bean. If I do a string_to_object on a stringified IOR from
within a standalone test program, it works fine. If I execute the same code
within the EJB container, I get a null pointer exception within the
string_to_object method.

The following code works perfectly unless it is run within the EJB
container:

String[] customProperties = new String[0];
String ior =
"IOR:010001011a00000049444c3a436f7354726164696e672f4c6f6f6b75703a312e30002
f4c01000000000000005a0000000101000010000000636f6e74726f6c736f6c7574696f6e0
0230600003a0000003a5c636f6e74726f6c736f6c7574696f6e3a54726164696e675365727
66963653a303a3a4946523a436f7354726164696e675f4c6f6f6b7570 00";
ORB theOrb = ORB.init(customProperties, null);
org.omg.CORBA.Object theObject = theOrb.string_to_object(ior);

When I run it within the EJB container, I get the following exception
inside Sun's string_to_object() method:

Any ideas of why this happens?
