Dear all,
Further to my recent problems with creating a simple web service and
getting only null values as return values (see below), I seem to have
located the problem.
WSDL2Java, which creates the required server-side files, doesn't seem
to implement the original method properly. In particular, the file
<MyClass>SoapBindingImpl.java, where the actual method implementation
is located, doesn't seem to be correct. For instance, I have the
following simple class:
package mypackage;
public class SayHello {
public java.lang.String hello(java.lang.String input) {
return ("Hello, " + input");
}
}
The class SayHelloSoapBindingImpl, which is created by WSDL2Java looks
like this:
package mypackage;
public class SayHelloSoapBindingImpl implements mypackage.SayHello{
public java.lang.String hello(java.lang.String input) throws
java.rmi.RemoteException {
return null;
}
}
Note the hard-coded null value that is returned instead of the
original implementation of the method. If I change this incorrect
implementation, everything works fine.
Am I missing something here? It seems like a lot of unnecessary extra
work, if I have to recreate all the methods when I start building real web
services. I'd rather avoid that.
Cheers,
Martin
