I have created the following stored procedure in SQL Server 2008

  Calculate the processinfected @ Concerned Int'l Out AS @infected = COUNT (*) Choose from userInfo where user id is not (select user id with deleted infoines);   
 Follow my Java code as is  
  infected with callbelt = con.prepareCall ("exec countInfected ()"); Infected.registerOutParameter (1, java.sql.Types.INTEGER); Infected.execute (); System.out.println ("infected" + infected.getINT (1));   
 but it generates the following error  
 
 java.lang.NullPointerException on core.dtable.Dbase.stored (Dbase.java:51)   
 Please guide me where I am wrong   
 
 
  try {Conn = DBC connection. SQLDB Conn.setAutoCommit (wrong); Callable Stattement CS = Faucet; Cs = conn.prepareCall ("call {dbo.xxCount (?)}"); Cs.registerOutParameter (1, java.sql.Types.INTEGER); Cs.execute (); System.out.println ("INFECTED" + cs.getInt (1)); } Hold (exception mistake) {
