thanks for the reply jaikiran.
I have worked according to instruction on
(I have not gone for named piped option.)
But i still get
Not Loaded in Repository Cache
### Instance 0 found in UCL org.jboss.mx.Loading.UnifiedClassLoader...."
But as i have kept the JNDI name 'MySqlDS', when the jboss server started, i could see a line saying that JNDI bound to name 'MySqlDS'.
Does it mean i would be able to connect to the mysql database.
Thanks & regards
