Alright guys, I'm trying to create a JDBC connection (or jndi) connection to a mysql database, and for some reason i think hibernate is not letting me. I can create a jsp on tomcat and it works there but not on jboss.

here is the code
 public String getDB(){
  | 	   String data = "";
  | 		
  | 		try{
  | 		InitialContext ctx = new InitialContext();
  | 		DataSource ds = (DataSource)ctx.lookup("mysqlDS");
  | 		Connection conn = ds.getConnection();
  | 		Statement statement = conn.createStatement();
  | 		ResultSet rs = statement.executeQuery("SELECT * FROM test");
  | 		
  | 		
  | 			try {
  | 				while (rs.next()) {
  | 					data += rs.getString("id") + " <br>";
  | 				  
  | 				   }
  | 			} catch (Exception e) {
  | 				// TODO Auto-generated catch block
  | 				e.printStackTrace();
  | 			}
  | 		
  | 			conn.close();
  | 		
  | 		}catch(Exception s){
  | 			   
  | 			s.printStackTrace();
  | 		}
  | 		
  | 		return data;
  |    }

Here is the DS file:

Pardon the junk code, but I'm just trying to get it working at the moment.   <?xml version="1.0" encoding="UTF-8" ?>

  --> 
- <!--  sql to call on an existing pooled connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers
    <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
      
  --> 
- <!--  corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) 
  --> 
- 
  <type-mapping>mySQL</type-mapping> 
  
  </local-tx-datasource>
  

Now, When i tried this with a JDBC connection it simply said that it was a null pointer, but this returns nothing. 

Here is the log output:
