Hi,
when I use the WSDL generated by my service to generate a stub using
wsdl2java this stub is not usable at runtime because the signatures do not
match the SEIClass generated from the same WSDL at runtime. Although I'm
guessing this should be easy I got stuck!
I have a simple echo service with one (string in string out) method
endpoint registered in a (custom extension of) CXFServlet. The WSDL it
generated contains seperate named ComplexType declarations for the
parameters. As a consequence(?) the stub from wsdl2java define a service
with en (bean in bean out) method. However when I try to use this code at
runtime I get this ServiceConstructionExceptoin...
Caused by: org.apache.cxf.service.factory.ServiceConstructionException:
Service class gxlabs.cxf.echo.service.EchoService does not implement the
echo method.
at
org.apache.cxf.jaxws.JAXWSMethodDispatcher.bind(JAXWSMethodDispatcher.java:54)
After some debugging I found out that the SEIClass does have a method name
"echo" but is has a string in string out signature! How did that happen?
I noticed that when I modify the WSDL by embedding the ComplexType
declarations in the Element tags this changes the stub to have the string in
string out signature as well and then does work.
Well, I do not understand what happend and why the same WSDL produces
different results using the same code? I am not using any binding or some at
this point. Is there some way (maybe do use binding) to make wsdl2java
generate a stub from the unmodified wsdl that will work at runtime?
I have copied some relevant snippets below. Any help would be much
appriciated! I am using CXF 2.2.2 deployed in felix.
Regards,
Bram
