Java Database Connectivity (JDBC)

I have a class

XDatabase.java

which performs all database functions (DML and DDL)correctly. This is a chunk of code..

public class XDatabase
{

  Connection con = null;
  Statement stmt = null;
  ResultSet rset = null;

  //Constructor
  public XDatabase()
  {
  }

  //Get database connection
  public void connectDatabase(String driver,String ip,int port, String SID, String userName,
                            String password)
  {
    try
    {
      Class.forName(driver);

      System.out.println("Connecting to the local database");

     //Assembling connection String
     String dbUrl ="jdbc:oracle:thin:@"+ip+":"+port+":"+SID; 

     con = DriverManager.getConnection(dbUrl,userName,password);

     System.out.println("Connection successsful!!! ");
    }
    catch(Exception e)
    {
      System.out.println("Error in connection ");
      e.printStackTrace();
    }

  }// End Constructor

Now when i create a project in JBuilder, and use the same fuction as above it gives me exceptions while loding the driver at line

Class.forName(driver)

The exceptions are as under:
