Mapping qname not fond for the package: org.hibernate.collection

[white bastion]

Greetings,

I am using Axis2-1.4.1, Hibernate(3.2), apache-tomcat-6.0.18.

I am able to persist java objects using Hibernate (REFER : Node.java and nodemapping.hbm) . (I have checked it, it works fine as a standalone stuff : DATA IS INSERTED IN TABLES).

Now, I am trying to integrate Hibernate with Axis2 by :
* placing all the .class files , .hbm.xml , hibernate.cfg files in the:
Tomcat\webapps\axis2\WEB-INF\classes folder
* placing all the hibernate related .jar in the:
Tomcat\webapps\axis2\WEB-INF\lib folder


Now when i run my application ,I am getting the error:
" java.lang.RuntimeException: Mapping qname not fond for the package: org.hibernate.collection"

(If, I remove the instance variable associations (which is of type List<String> ) from the Node class everything works fine and i am able to get all the data on the client side.)

 


package dataTypes;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;


public class Node {
	
	private static final long serialVersionUID = -908582556395326637L;
	
	private String nodeId;
	
	private String screenTerm;
		
	
	private List<String> associations;
	
	
	private String toolName;
	

	private String nodeType;
	
		
	public Node(){
		
	}
	
	public Node(String screenTerm,String nodeId,String toolName,String nodeType ) {
		this.screenTerm=screenTerm;
		this.nodeId=nodeId;
		this.toolName=toolName;
		this.nodeType=nodeType;
	}
	
	
	public Node(String screenTerm,String nodeId,ArrayList<String> associations,String toolName, String nodeType) {
	
		this.screenTerm=screenTerm;
		this.nodeId=nodeId;
		this.toolName=toolName;
		this.nodeType=nodeType;
		this.associations=associations;
	}
	
	
	
	public String getNodeId() {
		return nodeId;
	}
	
	public void setNodeId(String nodeId) {
		this.nodeId = nodeId;
	}
	
	public String getScreenTerm() {
		return screenTerm;
	}
	
	public void setScreenTerm(String screenTerm) {
		this.screenTerm = screenTerm;
	}
	
	
	public List<String> getAssociations() {
		return associations;
	}

	public void setAssociations(List<String> associations) {
		this.associations = associations;
	}
	
	public String getToolName() {
		return toolName;
	}

	public void setToolName(String toolName) {
		this.toolName = toolName;
	}
	
	
	public String getNodeType() {
		return nodeType;
	}

	public void setNodeType(String nodeType) {
		this.nodeType = nodeType;
	}
}


   

Mapping:

<?xml version="1.0"?>
  <!DOCTYPE hibernate-mapping PUBLIC
  "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
  "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
 
<hibernate-mapping>
	
	<class name="dataTypes.Node" table="Node" discriminator-value="PARENT">
		
		<id name="nodeId" type="java.lang.String" column="nodeId" >
			<generator class="assigned"/>
		</id>
	
		
		<property name="screenTerm" type="java.lang.String" column="screenTerm" />
		<property name="toolName" type="java.lang.String" column="toolName" />
		<property name="nodeType" type="java.lang.String" column="nodeType" />
		<list name="associations" lazy="true"  table ="associations_nodeId">
				<key column="nodeId" />
				<list-index column= "POSITION"/>
				<element type="string" column="associations" />
		</list>
	
	</class>
	
</hibernate-mapping>    

I have a hunch that as the WebServices are meant to be cross platform; one should not send Java-specific data types(List, ArrayList, HashMap etc etc), I should try to use an Array instead of list.
OR
I have not placed all the hibernate related .jars in the container ?

I created the .aar file using the eclipse plugin and the following server code:

 
package databaseAccess;
import java.util.ArrayList;

import dataTypes.Node;
import dataTypes.Screen;
import databaseAccess.AccessTopicMapStoredData;

public class InterfaceAccessTopicMapStoredData 
{
	

	public static  Node[] getNodes(String topicMapId)
	{
		String topicId="11111";
		System.out.println("**** Server's getNodes methodcalled by client ****" );
		System.out.println("****  getNodes topicMapId value is ****" + topicId );
		ArrayList<Node> nodeSet=AccessTopicMapStoredData.getNodes(topicId);
		Node[] nodeArray = nodeSet.toArray(new Node[nodeSet.size()]);
		System.out.println("**** Server's getNodes method exiting **** SIZE : " + nodeSet.size());
		return nodeArray;
		
		
		
	}
}

   

Here is the code which pulls the data from the data base:

  package databaseAccess;


import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import org.hibernate.Query;
import org.hibernate.Session;

import dataTypes.*;



public class AccessTopicMapStoredData {
	
static Session session = HibernateSessionFactory.getSession();

public static ArrayList<Node> getNodes(String topicMapId)
	{
		System.out.println("The value of the topicMapId id :" + topicMapId );
		
		ArrayList<Node> nodes=new ArrayList<Node>();
		
		Query query = session.createQuery("from Node");
		List results = query.list();
		Iterator iter = results.iterator();
		System.out.println("The size of the resultset after the query is"+results.size());
				
		while (iter.hasNext()) 
		{
			
			Node gs = (Node) iter.next();
			nodes.add(gs);
				
		}
		session.flush();
		//session.close();
		return nodes;
				
	}
}  

Here is the client code :

  

package databaseAccess;
import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference ;
import org.apache.axis2.client.Options;

import dataTypes.Node;
import dataTypes.Screen;


public class TmClient {


	 private static Logger log =Logger.getLogger(TmClient.class);
  
	 public static ArrayList<Node> getNodes(String topicmapid ) throws AxisFault  {
	  
		 
		
		 System.out.println("----  TmClient.getNodes(String topicmapid ) is started ---- ");
		 RPCServiceClient serviceClient;
		 serviceClient = new RPCServiceClient();
		
         Options options = serviceClient.getOptions();
         EndpointReference targetEPR = new EndpointReference("http://localhost:8080/axis2/services/NewService");
         options.setTo(targetEPR);
   
         QName opGetNode =new QName("http://databaseAccess", "getNodes", "ns"); 
         log.debug(opGetNode);
        
         Object[] opGetNodeArgs = new Object[] { };
