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
java.lang.SecurityException: class "com.microsoft.jdbc.base.BaseExceptions"'s signer information does not match signer information of other classes in the same package

yes...i deployed the EAR in WAS. But I don't know what this Classloader option is. I am using Rational Application Developer 7 for WAS 6.0. Can you please elaborate? Thx.

chaitu chaitu

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
Single class loader for application --- select this option

apply ok and save.

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.

chaitu chaitu

I told you select these options.......

Classes loaded with application class loader first ---- select this option
Single class loader for application --- select this option

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?

chaitu chaitu

ok i am using 6.1 version may be these options are there .can you send the screen shot of the classloader?
