I am very new to programming and Java is the language we are starting with so please bear with me as I enter this forum to extract as much of your knowledge as is morally possible.
I am currently working on a small application using JDBC:ODBC bridge.
All is going fine however, for some reason I get this error message:
"Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException".
now the strangeness of the situation is that I have run the program several times without any problems and I did not change anything!
So why would I all of a sudden receive this message?
