RE: Problem connecting to embedded JMS via JmsAdminServerIfc

Thanks for the reply Tim, I was getting a NullPointerException.

java.lang.NullPointerException
at 
org.exolab.jms.server.AdminConnectionManager.createConnection(AdminConnectionManager.java:174)
at 
org.exolab.jms.administration.intravm.IntravmJmsAdminConnection.<init>(IntravmJmsAdminConnection.java:93)
at 
org.exolab.jms.administration.AdminConnectionFactory.create(AdminConnectionFactory.java:283)
at 
org.exolab.jms.administration.AdminConnectionFactory.create(AdminConnectionFactory.java:186)
at com.bbn.test.JMSEmbeddedTest.main(JMSEmbeddedTest.java:21)

But, using JmsServer (as you suggested) seems to have fixed the issue, 
changed one line to two:
 >>new Thread(new 
EmbeddedJmsServer("C:\\eclipse-SDK-3.0.1-win32\\eclipse\\workspace\\JMSTest\\openjms.xml"));
becomes:
 >>JmsServer server = new 
JmsServer("C:\\eclipse-SDK-3.0.1-win32\\eclipse\\workspace\\JMSTest\\openjms.xml");
 >>server.init();

All other code and the config file left as it was, connection was made 
without any problem.  Thanks Tim!
