Hi
I am using JDBC adapter to access an Oracle Database.
I need to handle scenarios when the database is down.Typically I would want to send out emails to system administrators to take appropriate action.
To simulate the scenario mentioned above, I brought down my DB and tried to invoke a batch insert service.Below is the error which I get while doing the same:
java.lang.reflect.InvocationTargetException: com/wm/adk/error/AdapterConnectionException
at com.wm.app.b2b.server.JavaService.baseInvoke(JavaService.java:340)

I understand that the JDBC adapter throws AdapterConnectionException in case it is not able to connect to DB.So I should explicitly handle this exception and do whatever business processing I need to.
The problem starts when I try to do that.The AdapterConnectionException is present in wmart.jar which is not deployed in my server.When I deployed this jar in my server,all my adpaters start failing with the following error:
java.lang.NoClassDefFoundError: com/wm/pkg/art/data/IDataExt

I am not able to understand the cause for above error.
Any help is highly appreciated.
