    XA config causes SEAM to fail - what does working look like?

    William Woodman Master

      okay -

      fell over this by accident. Here goes. I've been developing a SEAM application and keep getting errors (see below)

      The error is something to do with datasource config.

      i've been trying to use an MYSQL xa config (eventally to go distributed).

      If i replace that with local resource only IT WORKS. NO errors.

      here goes here is the DS config. The XA config version (currently not in comments) is the one that causes my error. (i am using MySQL 5.1 and connector 5.1.5)

      Question now is why does the XA config error ? Wierd thing is this used work once up until about a 2 weeks ago when it all went squiffy and i've been pulling my hear out since .


      Does any one know/can guess and let me know whats wrong?
