Re: [xmlblaster] I_ConnectionProblems for subscribe / query clients
Marcel,
I observed some strange behavior after upgrading to the lastest cvs
version.
When starting up my publishing client, I get the following messages:
-------

--------- NOTE: I've replaced IP addresses with xxx -----
How do you turn JDBC off ?
Next, my code tries to establish an IOR connection, but fails:
