You haven't initialized the Statement (st). You need:
Statement st = conn.createStatement();
But before you can have this, you need conn (a Connection).
You'll have to modify the method to take a connection as a param or get one
in the method.

Subject: java.lang.NullPointerException:
Hi !!! I wrote the following Code and i got a problem !!!
its a method that returns a resultset, but id doesnt work on !!!
public ResultSet give_results (String val)
{
String chain;
try
{
chain="select id_reporte from reportes where id_is = " + val ;
System.out.println("Voy para alla con " + cadena );
rs = st.executeQuery(chain); // RIGHT HERE IT GIVES ME THE ERROR
!!!!!!!!!!!!!!!!(JAVA.LANG.NULLPOINTEREXCEPTION !!!! )
System.out.println("el resultset tiene: "+ rs.getRow() );
return rs;
}
catch (Exception e)
{
System.out.println("Error en Resultset: "+ e );
