Hi, Seem the same issue. Changed the {jbosshome}/server/default/lib/ojdbc14.jar file for a different version from oracle, and the issue went away. The one that worked had size 1536797 on disk, the one with the above issue, had size 1536979(this came from a standard install of Oracle Database 10g Release 10.2.0.1.0 - Production). Not sure of the exact reasons, but have seen a varying issues with different versions of this file across the 10.2.0.1 to 10.2.0.4 range. Your mileage may vary. Anyway, thanks for some pointers, and nice to know I am not alone.... Sc0tt.... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037444#...
