How encrypt password in datasource?

Hi,

I install LiveCycle ES on Jboss (Windows).
I configure JBoss to access Oracle. So I configure these files :
- adobe-ds.xml in server/all/deploy
- oracle-ds.xml in server/all/deploy
- login-config.xml in server/all/conf

In these three files, there is the username and password in clear.
Now I want to encrypt the password.
But I don't know how I have to change these file and what command I have to launch to do that.

Thanks for any help

Best regards,

Michael
