SQL datasource error for WAS 6.0

One of my application uses SQL datasource. I created a user-defined datasource in WAS 6.0 admin console and was able to successfully test the datasource. But when the application starts, the following error is returned...

00000025 FreePool      E   J2CA0046E: Method createManagedConnectionWithMCWrapper caught an exception during creation of the ManagedConnection for resource jdbc/NTSQLDB, throwing ResourceAllocationException.  Original exception: <=================================>Exception Message -> class "com.microsoft.jdbc.base.BaseExceptions"'s signer information does not match signer information of other classes in the same package

In the Admin Console -Enterprise Applications -you can see ur EAR -click on EAR -now you can see lot of options were with hyper links-click on Classloading and update detection-

 
Polling interval for updated files 0 Seconds----   give 0 seconds
Class loader order Classes loaded with parent class loader first
Classes loaded with application class loader first  ---- select this option
 
WAR class loader policy Class loader for each WAR file in application

The Lifecycle Approach to Managing Security Policy

Managing application connectivity and security policies can be achieved more effectively when following a framework that automates repeatable processes and ensures that the right activities are performed in the right order.

In RAD 7, I had the following options already selected...

Class Loading and File Update Detection  
Class loader mode -Parent First  
 WAR class loader policy - Module  
 Enable class reloading  - false
 Reloading interval  - 3

Even with above settings, I am getting the error.

krzy4uAuthor Commented:
WAS 6.0 on RAD 7 doesn't have those two options mentioned above. As I mentioned previously, it has only four attributes under Class Loading and File Update Detection -
1)Class loader mode
2)WAR class loader policy
3)Enable class reloading
4)Reloading Interval

Can you please help me find out other options that you were saying?
