OSB 3.0(ALSB 3.0) .Java Call out issue

Question

Hi,
I have written a Java code that invokes a stored Procedure. I want to use this piece of code in my ALSB 3.0 through Proxy Service Action(Java Callout).This code works fins when I run it as a Standalone Program.
But when I use this in Java Callout I face an issue.The code runs smoothly till the creation of the Callable Statement.*But after that the Statemant object turns out to be null.*
I do not see how calling a java method from ALSB 3.) could cause this issue.
Please help if any one is having any idea on this.

No, it does not take any Input as request.I try to get a standandrad method invocation.
The code
import java.sql.CallableStatement;
import javax.sql.DataSource;
import java.sql.Connection;
import javax.naming.InitialContext;
import javax.naming.Context;
import java.util.Properties;
public class TestJavaCallout {
     Context ctx=null;
     DataSource ds=null;
     Connection conn=null;
     CallableStatement stmt=null;
     String name="Test";
     public void callGenevaStoredProcedure()
          System.out.println("Test start");
          try
               Class.forName("weblogic.jndi.WLInitialContextFactory");
               Properties prop = new Properties();
          prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,
          "weblogic.jndi.WLInitialContextFactory");
          prop.setProperty(Context.PROVIDER_URL, "t3://localhost:7051");
          prop.put(Context.SECURITY_PRINCIPAL, "weblogic");
          prop.put(Context.SECURITY_CREDENTIALS, "weblogic");
          ctx = new InitialContext(prop);
          ds=(DataSource)ctx.lookup(name);
          conn=ds.getConnection();
          stmt=conn.prepareCall("call TestCall()");
          if (null!=stmt)//Here the stmt is NULL          {
               stmt.execute();
          System.out.println("Stmt is not null");}
          else
               System.out.println("Stmt is null");
          catch(Exception e){
               System.out.println("ErrorIn Catch121::"+e.getMessage());
               e.printStackTrace();
public class TestJavaCalloutCall
public static void call()
new TestJavaCallout().callGenevaStoredProcedure();
