Using custom exception inheritance

[dannox02]

I have a web service that I have defined to throw a custom exception, which works fine. However now I'd like to go a step further and define new exceptions that derive from that exception. For example:

My parent exception is ParentException, and it has two derived exceptions, ChildExceptionA and ChildExceptionB.

I'd like to be able to define my web service interface to throw ParentException, and be able to catch a ParentException on the client even if a ChildException was really thrown on the server (i.e. be able to catch child exceptions without having to explicitly declare them in the throws clause of the web method.

I found an article on how this can be done by modifying the WSDL here: http://www-128.ibm.com/developerworks/xml/library/ws-tip-jaxrpc.html.

Is there a way to do this type of thing using wscompile (starting from the SEI)?

Why not? Give it a try!!!

Well, I'm asking because I did try and it did not work. And I haven't been able to find a way to get it to work.

If the specifies that it throws a ParentException, but really throws a ChildException, the ChildException is not caught by the client.

My point is, that using wscompile to build the wsdl from the SEI does not include information in the wsdl about exception inheritance...

so I thought I'd ask if this was possible.

Anybody know about this?

Thanks,

Sorry for digging up this old thread, but I have the same problem and can't seem to solve it.

I have annotated the exception base class thrown by my WebMethods with @XmlSeeAlso to refer to the subtype exceptions, but it doesn't seem to have any effect and still in the client a SOAPFaultException is thrown instead of the user exception.

I am running JBoss AS 4.0.5 with JBossWS 2.0.1.GA.

What am I missing?

You have to use javax.xml.bind.annotation.* annotations. Take a look to Java Types To XML chapter of JAXB 2.1 specification.

I suggest you to write your wsdl first with exceptions inheritance inside and use wsprovide to generate the java artifacts for you. Then you can study them to get familiar how to do it.
