1. You forgot to login, then it runs fine (see attachment).

2. As you only publish (and don't want to receive)
  i removed the update() method in your example.
  (and  implements org.xmlBlaster.client.I_Callback is removed)

3. I have added args/help processing in main()
  Try 
     java TestBlaster -?


Don't forget to start the server as well:

  jaco org.xmlBlaster.Main


See 
  xmlBlaster/demo/javaclients/corba/ClientSub.java
how to subscribe or receive the message.

Start it where you wish and try

  java TestBlaster  -iorHost ahost.acompany.com

to locate it from your client if you
started xmlBlaster on the server "ahost.acompany.com"

You need only ONE xmlBlaster server of course.


Or for example use 

  java TestBlaster  -iorHost ahost.company.com  -iorPort 7609

if you wish another port. In this case xmlBlaster needs to
be startet on the other port as well:

  jaco org.xmlBlaster.Main  -iorPort 7609


You can even start xmlBlaster server in a thread of your
client using

  xmlBlaster/src/java/org/xmlBlaster/util/ServerThread.java

You find an example in the testsuite  TestFailSave.java.

Yes, you don't need TestCase
See 
  xmlBlaster/demo/javaclients/corba/
examples.
