Thanks for your help Anne. As recommended I opened a bug request yesterday.
It is already fixed, so I tried latest nigthly build (08/24/2006).
But now I get warnings (see below) at client code generation.
Aug 24, 2006 1:09:10 PM org.apache.axis2.schema.SchemaCompiler findClassName
WARNING: Type {urn:myNamespace}myStatus_type0 missing!
Aug 24, 2006 1:09:10 PM org.apache.axis2.schema.SchemaCompiler findClassName
WARNING: Type {urn:myNamespace}myStatus_type0 missing!
and here is my new wsdl file:

my XMl schema seems valid so I can't understand why

Subject: Re: [axis2]
NullPointerException with WSDL2Java
My guess is that the error is caused by the fact that you use the same
input message for both operations. Axis (and WS-I Basic Profile)
requires that each operation have a unique message signature (which is
the QName of the child element of the <soap:Body>). Both or your
operations use the same signature: "myNamespace"}myMethod.
The error might also be caused by the fact that "myNamespace" is not a
valid URI. A namespace must be a valid URI.
To fix your problem:
1. Change the target namespace to a valid URI (e.g., "urn: ")
2. Define unique input elements for your two operations
Meanwhile, WSDL2Java should not generate an NPE, so please also file a JIRA.
