Error while using Java bindings in BPEL (WSIF)

Question

Hi,
I have a requirement to invoke a java method from BPEL process using WSIF and get the response back from it.
MY java method accepts an input parameter which is object of anothe class.
When I tried to invoke the java class from BPEL, I am getting the following error:
[email protected] : Could not invoke 'getFullName'; nested exception is: org.collaxa.thirdparty.apache.wsif.WSIFException: Class 'com.services.test.Employee' is not compatible; nested exception is: java.lang.NullPointerException
Please find below the java class that I created:
package com.services.test;
import com.services.test.Employee;
import com.services.test.EmployeeFullRecord;
public class EmployeeRecord {
public EmployeeRecord() {
public static void main(String[] args) {
EmployeeRecord employeeRecord = new EmployeeRecord();
public EmployeeFullRecord getFullName(Employee emp) {
String fullName = emp.getFname() + emp.getLname();
EmployeeFullRecord emp1 = new EmployeeFullRecord();
emp1.setFullName(fullName);
return emp1;
The following is the wsdl that I created with JAva bindings:
<types>
<schema attributeFormDefault="qualified"
elementFormDefault="qualified"
targetNamespace="urn:EmployeeRecord"
xmlns="http://www.w3.org/2001/XMLSchema">
<complexType name="Employee">
<sequence>
<element name="fname" type="xsd:string" />
<element name="lname" type="xsd:string" />
</sequence>
</complexType>
<complexType name="EmployeeFullRecord">
<sequence>
<element name="fullName" type="xsd:string" />
</sequence>
</complexType>
</schema>
</types>
<message name="EmployeeRequestMessage">
<part name="emp" type="tns:Employee"/>
</message>
<message name="EmployeeResponseMessage">
<part name="emp1" type="tns:EmployeeFullRecord" />
</message>
<portType name="Employee">
<operation name="getFullName">
<input message="tns:EmployeeRequestMessage" />
<output message="tns:EmployeeResponseMessage" />
</operation>
</portType>
<binding name="JavaBinding" type="tns:Employee">
<java:binding/>
<format:typeMapping encoding="Java" style="Java">
<format:typeMap typeName="tns:Employee" formatType="com.services.test.Employee"/>
<format:typeMap typeName="tns:EmployeeFullRecord" formatType="com.services.test.EmployeeFullRecord"/>
<format:typeMap typeName="xsd:string" formatType="java.lang.String" />
</format:typeMapping>
<operation name="getFullName">
<java:operation methodName="getFullName" />
<input/>
<output/>
</operation>
</binding>
<service name="Employee">
<port name="JavaPort" binding="tns:JavaBinding">
<java:address className="com.services.test.EmployeeRecord"/>
</port>
</service>
Please let me know if I have missed out something.
THanks in advance!!!

Hi,
I have created another such service as above and placed the class files in <oraclehome>/bpel/system/classes and invoked the java code from bPEL.
Now i am getting the following error:
com.collaxa.cube.ws.wsif.providers.java.WSIFOperation_Java@98065 : Could not invoke 'createIdentity'; nested exception is: org.collaxa.thirdparty.apache.wsif.WSIFException: Class 'com.testx.wam.services.gen.identity.CreateRequest' is not compatible; nested exception is: javax.xml.bind.UnmarshalException: unexpected element (*uri:"",* local:"createRequest"). Expected elements are <{http://services.test.com/shared/xmlschema/user/1}CreateResponse>
My question is why am I getting URL as empty when I am actually passing the URL to the service. I have highlighted the uri which is showing as empty above.
Please help me solve this issue.
Thanks in advance!!!
