Encrypting Database Passwords

[dhamodh]

Hi,

We would like to configure MSSQL with JBoss with Database password encrypted.We tried the steps mentioned in the following link

http://wiki.jboss.org/wiki/Wiki.jsp?page=EncryptingDataSourcePasswords

But we got an error "Invalid Authentication Attempt:priciple=null".

Is there any solution for the above problem?

Thanks in advance.
