Summary: Problem connecting to MX4J 2.0.1 with Java 1.4.2

Initial Comment:

Hi!

When connecting mc4j under Java 1.4.2 to mx4j 2.0.1 I
get a NoInitialContextException (stacktrace below).

As a patch I modified
org.mc4j.console.connection.JSR160ConnectionNode (see
attachment):
- added method getDefaultInitialContext() to allow
setting the InitialContext
- modified connect() to use the given initial context
or a default context.
- added catch for SecurityException to provide a
usefull error message of principle/credential
combination is invalid.


Perhaps the connect() method has to be enhanced to use
the value of the system property for the inital
context,  before using a default value!

I would be glad, if you cut reenter my patch into the cvs!

Checked in and tested. Won't use the system property as 
mc4j is a standalone application that you won't usually want 
to set startup parameters for.

Thanks!
