Corba Use Case: CXF/JAX-WS Server and CXF/JAX-WS Client with corba:sequence
produces Unmarshalling Error: null
---------------------------------------------------------------------------------------------------------------
Key: CXF-2952
URL: https://issues.apache.org/jira/browse/CXF-2952
Project: CXF
Issue Type: Bug
Components: CORBA Binding
Affects Versions: 2.2.9
Environment: OS: XP and HPUX
Version: cxf-2.2.9 and cxf-2.3.0-SNAPSHOT
Components: java6, Sun's orbd
Reporter: Andrew Lamb
Using CORBA bindings, given the following types (in the corba wsdl), a
HelloWorld message succeeds if the inparameter is of type "MyItem" but not for
"MyItemVector".
<xs:complexType name="MyItem">
<xs:sequence>
<xs:element name="newMyString" type=" xs:string"></xs:element>
</xs:sequence>
</xs:complexType>
<xs:complexType name="MyItemVector">
<xs:sequence>
<xs:element maxOccurs="1000" minOccurs="0" name="item"
type="MyItem"></xs:element>
</xs:sequence>
</xs:complexType>
In the failure case, the CXF client fires off the request which triggers an
error on the CXF server: "org.apache.cxf.interceptor.Fault: Unmarshalling
Error: null".
Attached is a HelloWorld project based on the distribution sample "Hello World
CORBA Demo" (specifically "Use Case 3 - CXF/JAX-WS Server, CXF/JAX-WS Client")
which exposes the behavior.
To reproduce:
1. Untar ApacheCxfProblem.tar
2. Configure ApacheCxfProblem/config/.profile
export PROJECT_HOME=<full path>/ApacheCxfProblem
export CXF_HOME=<full path>/apache-cxf-2.2.9
3. From the ApacheCxfProblem/bin directory execute
. ../config/.profile
./runns.sh
./runserver.sh
./runclient.sh
Additional Notes:
Based upon the HelloWorld.idl, a wsdl file and java files were created using
the following commands:
idl2wsdl -o wsdl idl/HelloWorld.idl
wsdl2java -p com -d gen_src wsdl/HelloWorld.wsdl
