I have downloaded Jacorb 2.3.1 and I installed it. I run the demos in Jacorb but, I can not compile the foosample demo in. I get Null Pointer Exception when compiling the FooConsumer.class in line 115 and FooProducer.class in line 185 Is there anyone that can run the dds demo in Jacorb? Can you help me? Ender
