Unable to instantiate SapJCO

Hello

We are trying to use the SapJCO connector in two applications that we

have already installed on a WebSphere AppServer.

The problem is that the last application that is trying to instantiate

the class, throws an error saying " No

ClassDefFound: /com/sap/JCO$Exception".

We were reading on the web and we think that its possible that the

Sapjco connector could not be loaded by more than one application in a

Java Virtual Machine ( because of the use of static classes).

Is this so?

Thanks in advance,
