RE: [xmlblaster] Subscriber getting first message only - big clue!

["David Hooker" <dhooker at btrade.com>]

Well, if I call "new Global()" more than once, it prints a warning
message to the screen.  So the best thing I see is to do something like
this:

	global = new Global(Global.instance());

I hope that's the preferred way to create multiple Globals.  The 3-arg
constructor is very cumbersome.

Hallo David,
good to hear you found out the error since I was looking at a totally 
wrong place. Now everything is clear. If you use several clients within 
the same java virtual machine you should create one global for each 
client since there is one XmlBlasterAccess per global (kind of a global 
singleton).

Saluti
Michele
