------------------------------------
Summary: ClientProxyFactoryBean doesn't work with void methods
Key: CXF-6737
URL: https://issues.apache.org/jira/browse/CXF-6737
Project: CXF
Issue Type: Bug
Affects Versions: 3.1.1
Environment: DOSGi 1.7.0
Reporter: Amichai Rothman
I'm trying to use a simple ClientProxyFactoryBean to connect to a
dosgi-exported service. Without specifying the wsdl url, it doesn't work since
apparently the method argument names don't match (arg0 vs actual parameter
name, as explained in CXF-897), so I added the wsdl url. Now service methods
that have a return value seem to work ok, but those with void return type do
not.
Further investigation suggests that the issue might be in
ReflectionServiceFactoryBean: initializeWSDLOperation prints out a warning (no
method for op) instead of binding the operation, because initializeClassInfo
returns false, because initializeParameter called with the return type (near
the bottom of initializeClassInfo) returns false, since
o.getOutput().getMessagePart/getMessagePartByIndex return null (since there are
no parts - the method can throw an exception, for which the output message
exists, but there is no actual return type).
A quick test in the debugger shows that if I manipulate the flow manually (e.g.
execute the if caluse in initializeWSDLOperation after initializeClassInfo
returns) then the method invocation works ok.
I am not familiar with the inner workings of WSDL or these classes, so I'm not
sure what is the correct place to apply a fix.
