Corba Use Case: CXF/JAX-WS Server and CXF/JAX-WS Client with
corba:sequence produces Unmarshalling Error: null
Hello,
I’ve put together a fairly simple derivative of the “Hello World CORBA Demo”
(specifically “Use Case 3 - CXF/JAX-WS Server, CXF/JAX-WS Client”) which
may be showing a defect.
This began as a rather large, complicated corba idl from an external vender
which I converted to wsdl using the cxf idl2wsdl utility. Testing this
using a simple CXF/JAX-WS Server and CXF/JAX-WS Client, one particular
operation produced the exception “org.apache.cxf.interceptor.Fault:
Unmarshalling Error: null” on the server. After verifying that all objects
were getting fully initialized by the client without any nulls, I began
paring away everything from the wsdl that wasn’t pertinent to this
particular scenario.
What I’ve found is that given the following types, a HelloWorld message
works 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>
So based upon these findings, I’ve attached a HelloWorld project that
hopefully will make reproducing this behavior fairly easy. (Note: I’ve only
included the wsdl—not the original idl. I can produce that as well if this
would help.) I’ve reproduced this on XP as well as HPUX and using both
cxf-2.2.9 and the cxf-2.3.0-SNAPSHOT and I’ve been using java6 and Sun’s
orbd.
To reproduce
1. Untar ApacheCxfProblem.tar
http://cxf.547215.n5.nabble.com/file/n2266930/ApacheCxfProblem.tar
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
Thanks,
Andrew
Here is a snippet of my client code:
SayingHelloCORBAService s = new SayingHelloCORBAService();
SayingHello client = s.getSayingHelloCORBAPort();
MyItem item = new MyItem();
item.setNewMyString( "6010" );
MyItemVector vector = new MyItemVector();
vector.getItem().add( item );
System.out.println("Invoking greetMe... ");
String result = client.helloWorld( vector );
System.out.println("greetMe.result=" + result);
And resulting stack trace on the server:

Re: Corba Use Case: CXF/JAX-WS Server and CXF/JAX-WS Client with corba:sequence produces Unmarshalling Error: null
Posted by Daniel Kulp <dk...@apache.org>.
Any chance I can get the IDL for that simple service in the tar. I'd like to
create a pure CORBA client and server for it like we have for the CORBA demos.
That should help narrow down where the problem is. If the client can talk to
the pure CORBA server, we know the problem is in the reading/unmarshalling.
If the pure CORBA client can talk to the CXF server, we know the unmarshalling
is OK. If nothing can talk to anything, we're really screwed. :-)
At the very least, it would help narrow down where the problem is.
