Error encountered: Unable to resolve target object: testsoap.TestWsImpl

[Phoay Phoay Koay]

Hi all,

I 'm trying to develop a web service using SOAP with database connection. Three files areinvolved :

testsoap.TestWsImpl.java, testDD.xml,

testsoap.client.TestClient.java

 

My Implementation calss is

package testsoap;

 

import java.io.*;
import java.lang.*;
import java.sql.*;
import java.util.*;

 

public class TestWsImpl
{
 
  public TestWsImpl()
 { 
 }

 

 //******************************************************************//
 // callConnection
 // TODO : To get connection
 //******************************************************************//
 public Connection callConnection()
 {
  Connection conn =null;
  try
  {
       Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
       conn = DriverManager.getConnection("jdbc:odbc:ws","ma","ma");
  }
  catch(Exception ex)
  {
  }
  return conn;
 }

 

 //******************************************************************//
 // Function:getBookTitle
 //******************************************************************//
  
 public String getBookTitle(String artist)
 {
  PreparedStatement stmt;
  ResultSet rs;
  String retValue="";
   String query ="";
  Connection conn = null;
  try
  {
     
   
   conn = callConnection();   
   query = "select bookTitle from dbo.pptest where bookArtist = ?";
   stmt = conn.prepareStatement(query);
   stmt.setString(1,artist);
   rs = stmt.executeQuery();
   
   while(rs.next())
   {
    retValue =rs.getString(1);
   }
   System.out.println("Book Title For " + artist + " : " + retValue);
   rs.close();
   stmt.close();
   conn.close();
   conn = null;
     
  }
  catch(Exception e1){
   if (conn!=null)
   System.out.println("getBookTitle() : Release Connection Failed! ");
   return null;
  }  
  return retValue;
}
 

 
}

Result :

Book's Artist Name : John

Error encountered: Unable to resolve target object: testsoap.TestWsImpl

 

Can anybody tell me that what is happening to the classpath that i set? What is the solution for this case?

Thanks in advance.
