Subject [jira] Created: (AXIS-2586) Wrapped/Literal encoding and abstract parameters with arrays won't work.

Wrapped/Literal encoding and abstract parameters with arrays won't work.

                 Key: AXIS-2586
             Project: Apache Axis
          Issue Type: Bug
          Components: Serialization/Deserialization
    Affects Versions: 1.4
         Environment: Tomcat 5.5
Windows XP SP2
            Reporter: Steve McDuff

I found a problem when passing abstract parameters with array fields to a method in Wrapped/Literal

Steps to reproduce
1 - create a base class that has an array field of itself.
2 - create a sub class that inherits from the base class
3 - create a service class to publish as a web service that uses the base class as a paramter
for a public method
4 - use Java2WSDL to publish the service class using wrapped/literal encoding
5 - run the web services on a web server
6 - use WSDL2Java to create stubs for a test client
7 - use the test client to call the method on the service class with a Sub Class instance.
8 - notice that the call to the service fails with the error : org.xml.sax.SAXException: Invalid
element in BaseClass - item

Here are the code samples:

class BaseClass{
    private BaseClass[] childArray;
    public BaseClass[] getChildArray(){
        return childArray;
    public void setChildArray(BaseClass[] childArray){
        this.childArray = childArray;

class SubClass extends BaseClass{
    private BaseClass[] otherChildArray;
    public BaseClass[] getOtherChildArray(){
        return otherChildArray;
    public void setOtherChildArray(BaseClass[] otherChildArray){
        this.otherChildArray = otherChildArray;

// Use Java2WSDL to publish this as a web service
class MyTestInterface{
    // send and return the same base class parameter
    public BaseClass sendBase(BaseClass base){
        return base;
    // this method just declares sub to make sure it finds its
    // way in the WSDL
    public void declareSub(SubClass sub){};

// client unit test code
class MyTest extends junit.framework.TestCase{
    public void testSendBase(){
        // Insert code to resolve URL and locate the web services here
        MyTestInterface x = null;
        SubClass sendSubClass = new SubClass();
        sendSubClass.setChildArray(new BaseClass[]{new SubClass()});
        // this call will fail with the message
        // org.xml.sax.SAXException: Invalid element in BaseClass - item
        BaseClass retVal = x.sendBase(sendSubClass);
        assertEquals(sendSubClass, retVal);

- This problem is reproducible in Document/Literal
- This problem is not reproducible in RPC/Encoded
