[jacorb-developer] Running Jacorb Demos

Fri Dec 10 20:01:30 CET 2010

Hi Guys,

I have extracted the jacorb-2.3.1.bin.zip file into my home directory and
run the command "ant scripts" as instructed in the installation page.
I then tried to run the arrays demo in the demo directory by performing the
following operations:
1. cd arrays
2. idl -fall server.idl
3. javac *.java
4. cp *.class demo/arrays
5. ns
-Djacorb.naming.ior_filename=/home/user/Project/Java/CORBA/NamingService/NS_Ref
6. jaco demo.arrays.Server -Djacorb.config.dir=. -DORBid=DemoArray
7. jaco demo.arrays.Client -Djacorb.config.dir=. -DORBid=DemoArray

The example seems to work however the nameservice and the server giving out
the following messages
Why is this so?
Error messages given by nameservice and demo.arrays.Server:
 2010-12-10 16:59:07.133 FINE Transport to 127.0.1.1:60752: stream closed on
