Composing axis2 webservices
Hi All,
I'm using axis2-1.4.1 and Eclipse/WTP and want to create the following two services:
* A service "f" that produces a result of type "A"
* A service "g" that consumes an input of type "A"
Next, I would like to make the service composition g(f()). In other words, I would like to pass the result of service "f" to the service "g".
My problem is that the generated client stubs contain incompatible class definitions for type "A", making the service composition impossible.
The problem is that both definitions are defined as static inline classes of the corresponding services.
Something like:
public class fStub {
...
public static class A {}
...
}
public class gStub {
...
public static class A {}
...
}
Since both definitions of A are in different name spaces (fstub.A and gStub.A, respectively), the classes are incompatible.
On the server side this is not a problem, because there the generated class definition for "A" uses the namespace as defined in the wsdl.
Could someone indicate how to solve this problem? Am I doing things wrong?
Any help would be greatly appreciated.
Kind regards,
Merijn de Jonge

Dear Anne,
Thanks for your reply.

That is exactly what I did! However, it turns out that the "-u" switch of wsdl2java must be used in order to "unpack the databinding classes". Only this way the generated classes will be generated in separate packages, rather than inlined in the service stub class.
However, this switch is not turned on by default when generating client code. In the WTP framework of eclipse, I don't know how to turn this switch on (although it seems to be on for generating server code). Consequently, when generating a java bean skeleton (i.e., the server code) from a wsdl file the generated code is perfect, but when generating the corresponding client code I get these static inline classes.
The only solution I found thus far is by generating the client code by hand (i.e., by running "wsdl2java -u" by hand).
This is of course not really the way software development using WTP should look like.
Is there something I do wrong, or did I miss a configuration setting, or is it a problem of WTP that needs to be fixed?
Kind regards,
Merijn

You should use the "WSDL first" method to build these services. Define
a common schema that defines the "A" type, and then import that schema
into your WSDLs.
