[xmlblaster] problems with Jacorb 1.4.50 as part of xmlblaster

[Michael Atighetchi <matighet at bbn.com>]

After upgrading to the lastest xmlblaster from CVS, I noticed that the
version of JacORB changed from 1.3.30 to 1.4.50. In addition, I
started getting the following exception in a slave plugin

My plugin class PublishLenChecker tries to instantiate an ORB in
AlertProducer to communicate to other CORBA components.

	// initialize ORB 
	java.util.Properties orbprops = new java.util.Properties();
	orb = ORB.init(args, orbprops);

I believe this is due to a JacORB version mismatch. I'm actually
compiling my code against JacORB 1_4_1, and xmlblaster is compiled
against 1.4.50. 

What is the best way to get my code and xmlblaster to the same version
of JacORB ? I'm willing to move away from 1_4_1 to the version
xmlblaster uses, but woud like to know what version it is (and would
like to be informed if it changes within xmlblaster).

Michael
