Why don't you print the exception message? "Something is wrong" does not give us a lot of info.
You don't show us where and how you create the connection.

The exception tells you at what line of the code the error is.
Note: it is a general Java issue (a null pointer exception), not a database issue.

The application runs fine if I run it in offline mode; no database connection. The errors are thrown when trying to connect to the database.

Line of code that it don't like when in online mode:



= at pall.PaLLmeny.<init>(PaLLmeny.java:80)

Thoughts?

Some variable is null, and something in your code does not like that that variable is null.

If you are using an IDE like Eclipse, use the debugger. You will know where the exception is throwing.
 
I agree. Here's the link: http://aspose.com/file-tools
