I have downloaded a driver for postgres to develop
in java, the driver i downloaded is jdbc7.0-1.2.jar
It works just fine untill i try to do something
with the database from an event listener class.
Then it blows up with a java null pointer
exception.
Everywhere else in the program i can read and write
to the database but when i try to write a record into the database from the
listener class i get null pointer error.
I have looked through it with the debugger and i
have found out that the pgstream variable was null when i
tried using the driver from the listener class and it has some values when i try
to use it from anywhere else.
I will attach the code i am trying to build, you
can run it and see what happnes, i have used Jbuilder 5.0 to run this
code.
Thanks in advance,
Roman Levandovsky.
