IBM WSAD 4.0.3 - getting the DataSource object

Question

Hi guys , i had posted a DataSource question before...but i was able to figure that out. My new problem is that i cant get the DataSource object in my java program and the following error is thrown.
java.lang.NoClassDefFoundError: com/ibm/ejs/ras/TraceElement
     at java.lang.Class.forName0(Native Method)
     at java.lang.Class.forName(Class.java:212)
     at com.sun.naming.internal.VersionHelper12.loadClass(VersionHelper12.java:46)
     at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:656)
     at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:247)
     at javax.naming.InitialContext.init(InitialContext.java:223)
     at javax.naming.InitialContext.<init>(InitialContext.java:199)
     at DataSourceCheck.main(DataSourceCheck.java:27)
Exception in thread "main"
Here is my Java program :
import java.sql.*;
import javax.naming.*;
import java.util.*;
class DataSourceCheck
     public static void main(String[] args)
          javax.sql.DataSource myDataSource= null;
          try
               String initialContextFactory = "com.ibm.websphere.naming.WsnInitialContextFactory";
               String providerURL = "iiop://localhost:8081";
               java.util.Properties props = new java.util.Properties();
               props.put(Context.INITIAL_CONTEXT_FACTORY, initialContextFactory);
               props.put(Context.PROVIDER_URL, providerURL);
               Context myContext = new InitialContext(props);
               Connection myConnection = myDataSource.getConnection();     
          catch (Exception e)
               e.printStackTrace();
               System.out.println();
I start a Server instance from IBM WSAD and it runs on 8081.
Please suggest what to do .

sorry..i forgot to delete that line...its a typing eror.
Here is the code again....
I fail to get the context.
import java.sql.*;
import javax.naming.*;
import java.util.*;
class DataSourceCheck
     public static void main(String[] args)
          javax.sql.DataSource myDataSource= null;
          try
               String initialContextFactory = "com.ibm.websphere.naming.WsnInitialContextFactory";
               String providerURL = "iiop://localhost:900";
               java.util.Properties props = new java.util.Properties();
               props.put(Context.INITIAL_CONTEXT_FACTORY, initialContextFactory);
               props.put(Context.PROVIDER_URL, providerURL);
               Context myContext = new InitialContext(props);
               //myDataSource = (javax.sql.DataSource)myContext.lookup("jdbc/oracle/OracleDataSource");
               //Connection myConnection = myDataSource.getConnection();     
          catch (Exception e)
               e.printStackTrace();
               System.out.println();
