ExceptionHandling Web Services

[muz dogru]

I have made own Exception classes, which extend from Exception. When I
throw a new MyException("my error message"), then catch the error and
print the message, it's all fine within an application. But when I throw
a new MyException in a Web Service and catch it on the "other side", I
only get the message that an Exception was thrown, but not the exact
error message.

How do I have to handle own Exceptions? Is there a good tutorial? Thanks
a lot.

Hi Muz!
I believe this is because webservices throw ONLY soap exception whenever
something go wrong within a webmethod so even if the error was something
like connection to DB error that the method try to accomplish , what is
thrown to the client is the soap exception so you might need to attach your
massage to that in your case . checkout this link, hope it helps

hello mohammas,

ok, it seems as if I have to throw a SoapException in every case. Thanks
for the link, that works fine, but the returned ErrorMessage is
something like:

System.Web.Services.Protocols.SoapException: invalid AccountId at
blabla.myThrow(SaferpayException e) in balblaWebService.asmx.cs:line 109
at blablaMethod(string message) in blabla.asmx.cs:line 56

This ErrorMessage is very long and I also don't want the user to know in
which file the exception occured. I just want them to see "invalid
AccountId". Isn't that possible?

Thanks,
Muz
