Hi,
I am trying to retrieve data from a database and I am getting the following error message:
Exception in thread "main" java.lang.NullPointerException at Dbase.main(Dbase.java:40).
Dbase is the name of my database. How can I overcome this error, PLEASE HELP.
I am currently having problems with my internet connection so may you please forward the solution to patrickm@riz.co.zw.
Thanks
