Fault and exception handling
Hi,
I'm looking for examples of how fault and exception handling is done??
I'm writing a SOAP web service in Java.

I am not certain what you mean by "fault and exception handling". You
say you are writing a service. The service does not need to have
anything specific to SOAP. You can handle exceptions the way you always
would, both catching exceptions you don't want propagating to the client
and throwing exceptions. The Apache SOAP code will ultimately return a
SOAP fault to the client when your service throws an exception. If you
want your faults to contain some specific information, you can write a
custom fault handler. See
http://xml.apache.org/soap/docs/guide/errors.html.
The "standard" client code is something like this code from the
addressbook sample:
// Invoke the call.
Response resp;
try
{
resp = call.invoke(url, "");
}
catch (SOAPException e)
{
System.err.println("Caught SOAPException (" +
e.getFaultCode() + "): " +
e.getMessage());
return;
}
// Check the response.
if (!resp.generatedFault())
{
Parameter ret = resp.getReturnValue();
Object value = ret.getValue();
System.out.println(value != null ? "\n" + value : "I don't
know.");
}
else
{
Fault fault = resp.getFault();
System.err.println("Generated fault: " + fault);
}
