Tracing SOAP-ENV:Server.Exception errors

Question

Hi,
I have generated my WebServices from an ADF Application Module using Jdeveloper 10.1.2.1.
After deploying the Web Services to the Application Server I call the web service test screens i.e. http://machine:port/MyWebServicesPath/MyWebService to check that the deployment has been successful.
When I enter the required values into the test screen occasionally I receive a SOAP response that contains error messages that are not being returned from my application code
e.g.
faultcode = FaultSOAP-ENV:Server.Exception
faultstring = oracle.jbo.common.ampool.ApplicationPoolException: JBO-30003: The application pool (package1.MyServiceLocal) failed to checkout an application module due to the following exception:
faultactor = /MyWebServicesPath/MyWebService
Checking the logs written by the web service application code confirms that these errors are thrown before the values reach the application code.
Are there any logs that would give me a clearer picture of what the problem is as tracking down the problem by trial and error often requires multiple time-consuming redeployments.
Thanks in advance
Lisa

Hi Lisa,
From a quick search with google on JBO-30003, it seams to indicate that the most common error condition is a dead connection to the underlying database.
The ADF Application Module that you are exposing as a service is most likely to be the one throwing this error. The SOAP server is then wrapping this runtime error into a SOAP fault with the code,actor and string that you see.
Hope this helps,
Eric
