Re: General error handling question

[D P]

Thank you for the feedback.  I presume you're referring to wsdl: fault elements?  Please correct if wrong, but that would only work if the exception was expected and caught somewhere in the service, and I'm looking for something in axis2 which catches unhandled exceptions that get thrown up into the axis2 stack.  The reason why I'm looking at axis2 is that it is the single central path through which unhandled exceptions are thrown, and trying to standardize this type of error handling at the service level would be time consuming, difficult to standardize, and (in the example below) may not be the best design solution.  Perhaps a code example would help:

public class FooSkeleton implements FooSkeletonInterface {

    public void init(ServiceContext serviceContext)
            throws NamingException {

        Context initalContext = new InitialContext();
        dataSource = (DataSource) initalContext
                .lookup((String) axisConfiguration.getParameter(
                        AxisServlet.JNDI_DATASOURCE_NAME ).getValue());
    }
}

Let's say there are multiple services with this kind of init() method, and let's say a naming exception is thrown.  The services can't function without the datasource so there isn't any action the init() method can take if the exception occurs other than to rethrow it. Axis2 would eventually catch this exception and format the exception message as a soap fault.  I would like to either a) see if a mechanism already exists that allows me to configure axis2 to send a generic fault message instead (other than just shutting off the stack trace), or b) see if there is anything in the axis2 API that would allow me to hook into the error handling to customize it.

Hopefully this clarifies things, please let me know.

If you're using WSDL, just define an error message as a string and

with success messages. Otherwise, not sure.
