Subject Pass an Object (example) - Need an own Serializer?
Date Sun, 28 Jul 2002 20:29:56 GMT

Finally I could manage to install the Tomcat and Axis 3 after 8 hours on
my Laptop.  PC doesn't still work. (Execption)

I could successfully deploy a simple "Helloworld" class.
Now I want make a simple thing: passing an UserData object.

package step.objects;

public class UserData {
	private String _userName;
	private int _userAge;
	public void setUserName (String userName){
		_userName = userName;
	public String getUserName (){
		return _userName;
	public void setUserAge (int userAge){
		_userAge = userAge;
	public int getUserAge (){
		return _userAge;

package step.objects;

public class Wrapper {
	public UserData receiveObject() {
		UserData obj=new UserData();
		obj.setUserName ("John");
		obj.setUserAge (27);
		return obj;			

So far its very easy.  I deploy the Wrapper Class, and the WSDL file has
a complex Type for UserData. Everything runs perfect.

Now I use WSDL2JAVA and make some Classes which I need for the Client

I show you just my main class:

package localhost;

public class start {

	public static void main(String[] args) throws Exception {
		WrapperService service = new WrapperServiceLocator();
		Wrapper port = service.getreceiveObject ();

		step.objekts.UserData tmp;
		tmp=port.receiveObject ();

AXIS made this UserData class which is used above automatically.  
I thought AXIS would use BEANS to serialize and deserialize the objects,
but it seems that I need my own serializer.

The error message is:
- Mapping Exception to AxisFault
 faultCode: {}HTTP
faultString: (500)Internal Server Error
faultActor: null
... No serializer found for class step.objekts.Objekt
in registry org.apache.axis.encoding.TypeMappingImpl@e434d
Caused by: No serializer found for class
step.objekts.Objekt in registry

What could be the problem?

UserData (made by AXIS)

package step.objects;

public class UserData implements {
    private java.lang.String userName;    
    private int userAge;

    public UserData() {

    public java.lang.String getUserName() {
        return userName;

    public void setUserName(java.lang.String userName) {
        this.userName = userName;

    public int getUserAge() {
        return userAge;

    public void setUserAge(int userAge) {
        this.userAge = userAge;

    private Object __equalsCalc = null;
    public synchronized boolean equals(Object obj) {
        if (!(obj instanceof UserData)) return false;
        UserData other = (UserData) obj;
        if (obj == null) return false;
        if (this == obj) return true;
        if (__equalsCalc != null) {
            return (__equalsCalc == obj);
        __equalsCalc = obj;
        boolean _equals;
        _equals = true && 
            ((userName==null && other.getUserName()==null) || 
             (userName!=null &&
              userName.equals(other.getUserName()))) &&
            userAge == other.getUserAge();
        __equalsCalc = null;
        return _equals;

    private boolean __hashCodeCalc = false;
    public synchronized int hashCode() {
        if (__hashCodeCalc) {
            return 0;
        __hashCodeCalc = true;
        int _hashCode = 1;
        if (getUserName() != null) {
            _hashCode += getUserName().hashCode();
        _hashCode += getUserAge();
        __hashCodeCalc = false;
        return _hashCode;

    // Type metadata
    private static org.apache.axis.description.TypeDesc typeDesc =
        new org.apache.axis.description.TypeDesc(UserData.class);

    static {
        org.apache.axis.description.FieldDesc field = new
        field.setXmlName(new javax.xml.namespace.QName("", "userName"));
        field = new org.apache.axis.description.ElementDesc();
        field.setXmlName(new javax.xml.namespace.QName("", "userAge"));

     * Return type metadata object
    public static org.apache.axis.description.TypeDesc getTypeDesc() {
        return typeDesc;

     * Get Custom Serializer
    public static org.apache.axis.encoding.Serializer getSerializer(
           String mechType, 
           Class _javaType,  
           javax.xml.namespace.QName _xmlType) {
          new  org.apache.axis.encoding.ser.BeanSerializer(
            _javaType, _xmlType, typeDesc);

     * Get Custom Deserializer
    public static org.apache.axis.encoding.Deserializer getDeserializer(
           String mechType, 
           Class _javaType,  
           javax.xml.namespace.QName _xmlType) {
          new  org.apache.axis.encoding.ser.BeanDeserializer(
            _javaType, _xmlType, typeDesc);
