Subject Re: helloworld sample simpleType restriction not working
Date Fri, 25 May 2007 02:01:30 GMT
Hi Feng,

Brice is correct, generated stub can't do the schema validation.
But if you run client from ant client, you will see we do this schema 
validation since by this way, we pass in wsdl to the client, so the 
client can build service model from wsdl, which include the schema 
In fact, we show this feature in the demo code, in client main line you 
can see

System.out.println("Invoking greetMe with invalid length string, 
expecting exception...");
        try {
            resp = port.greetMe("Invoking greetMe with invalid length 
string, expecting exception...");
        } catch (Exception e) {
            System.out.println("Expected exception has occurred: " + 

Thanks very much
