Hi I try to connect to postgreSql server from my bean on Jboss.
When I execute query in simple java class it works and when I put it into EJB it crush down.
query is very simple just to test if its working :
String sql = "SELECT * FROM urzytkownicy";
ResultSet rs = stmt.executeQuery(sql);
It is in public method in EJB ... I try to run it from a client
I receive an error :
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.ServerException: RuntimeException; nested exception is:
java.lang.NullPointerException
