WARNING: Problem validating implementation class. Exception declaration mis

Question

I have created sample class using JDevStudio10.1.3
Added method getX() throws Ex (Ex implements Exception)
Select class and generated J2EE 1.4 RPC webservices
Got the warning :
Generating WSDL and mapping file
WARNING: Problem validating implementation class. Exception declaration mismatch between Implementation: mypackage.Class3 and Interface: mypackage.MyWebService3. Impl class Method: X declares exceptions not declared by the interface (mypackage.Exp)
Now When I generated client proxy from the wsdl generated, Ex class is not getting generated.
Can some one help me please.
Thanks in advance

If you are using Ex in the implemetation class, make sure that you also include the same in the interface (or SEI).
If the implementation looks something like:
public void doSomething() throws Ex {
System.out.println("Is there something to do, now ?");
then the SEI should be:
public void doSomething() throws Ex, RemoteException;
If your have ommited Ex, then you will have the warning you are seing, and there wont be any artifact generated for Ex in the WSDL.
Because the Ex exception was not mapped to any WSDL artifact, there is no way you will see the Ex exception generated on the client side (or proxy).
I have been able to reproduce your error message, so you should be all good.
WARNING: Problem validating implementation class. Exception declaration mismatch between Implementation: bugyyy.MyServiceImpl and Interface: bugyyy.MyWebService. Impl class Method: doSomething declares exceptions not declared by the interface (bugyyy.Ex)
Hope this helps,
