CXF Apache: null pointer problem with my reponse
Hello,
I have a big problem with reception of a CXF answer and i'm looking for a
solution since many days. In my aut-generated classes, i have a null
pointer.
I use "apache-cxf-2.1.2". From a wsdl file, with https, i've auto-generated
many classes with wsdl2java. My application send a request to LDAP server
with webservice (using https). Communication work fine: my request is sent
and web service send me a correct response. I think my problem is in these
auto-generated classes with wsdl2java, because at the reception of the
response, inside of the response class (a bean), the pointer to another
class (an other bean), is null and my response (in log) is correct and well
formed (like in util soapUI).
For more information, here is my request xml:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:urn="urn:ldaplogonwsdl">
<soapenv:Header/>
<soapenv:Body>
<urn:connect>
<user>
<!--You may enter the following 2 items in any order-->
<login>user</login>
<pwd>pwd</pwd>
</user>
</urn:connect>
</soapenv:Body>
</soapenv:Envelope>
Here is my response:
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<connectResponse xmlns="urn:ldaplogonwsdl">
<return>
<answer>SUCCESS</answer>
<userid>11111</userid>
<login>user</login>
<nom>name</nom>
<prenom>surname</prenom>
name@domain.fr
<fonction>
<code_entite>111</code_entite>
<titre>test</titre>
</fonction>
</return>
</connectResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Here is the auto-generated code with wsdl2java for response:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "connectResponseType", propOrder = {
"_return"
})
public class ConnectResponseType {
@XmlElement(name = "return", required = true)
protected ConnectedUser _return;
public ConnectedUser getReturn() {
return _return;
}
public void setReturn(ConnectedUser value) {
this._return = value;
}
}
The "_return" pointer has value null at response time.
Here is my call code:
URL wsdlURL = new URL("https://adress/ldaplogon?wsdl");
QName SERVICE_NAME = new QName("urn:ldaplogonwsdl", "ldaplogonwsdl");
Ldaplogonwsdl ss = new Ldaplogonwsdl(wsdlURL, SERVICE_NAME);
LdaplogonwsdlPortType port = ss.getLdaplogonwsdlPort();
org.apache.cxf.endpoint.Client client = ClientProxy.getClient(port);
HTTPConduit httpConduit = (HTTPConduit) client.getConduit();
TLSClientParameters tlsParams = new TLSClientParameters();
tlsParams.setSecureSocketProtocol("SSL");
httpConduit.setTlsClientParameters(tlsParams);
HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
httpClientPolicy.setConnectionTimeout(36000);
httpClientPolicy.setAllowChunking(false);
httpClientPolicy.setReceiveTimeout(32000);
httpConduit.setClient(httpClientPolicy);
ConnectRequestType _connect_parameters = new ConnectRequestType();
User myUser = new User();
myUser.setLogin(username);
myUser.setPwd(password);
_connect_parameters.setUser(myUser);
ConnectResponseType _connect__return = port.connect(_connect_parameters);
System.out.println("_connect__return=" + _connect__return);
ConnectedUser connectedUser = (ConnectedUser) _connect__return.getReturn();
And connectedUser has value null.
Please, could you help me?
Thank you in advance,
Vincent

Re: CXF Apache: null pointer problem with my reponse
Posted by Daniel Kulp <dk...@apache.org>.
Most likely, the response message is actually wrong according to the
schema.
The request message makes it look like the element form of the schema is
set to "unqualified". The "urn:connect" element is qualified properly,
but the child elements (user, etc...) are not namespace qualified.
The response message, however, puts all the elements into
the "urn:ldaplogonwsdl" namespace. If the schema says that the xml
should be unqualified, then the message is wrong. CXF will not know how
to deserialize it.
