RE: openJMS newbie question

It appears to be due to a class loader bug in commons-logging. There
are several bugs [1] related to this issue which appear to have been fixed 
in the commons-logging-1.0.5-alpha1 release [2].
You could also try going back to commons-logging-1.0.3 [3] 
 
Let us know how you go.
 
Regards,

Subject: [openjms-user] openJMS newbie question


the code 

Hashtable properties = new Hashtable(); 
 
properties.put(Context.INITIAL_CONTEXT_FACTORY,"org.exolab.jms.jndi.InitialC
ontextFactory"); 
           properties.put(Context.PROVIDER_URL,"tcp://localhost:3035/"); 
           Context context = new InitialContext(properties); 

crashes on the last line with the following stack trace 

What am I doing wrong? 
thanks,
