Dear Greenhorns,

First of all sorry my english writing.
I installed JavaJDK 7u13 with NetBeans 7.2.1 and db-derby-10.5.3.0-bin.zip on a fresh OS. Then i set the environment variables according to their relative paths as seen below. By using ij the test database and the test table created, records inserted and displayed by using select. In command line and also in NetBeans IDE the HelloWorld console app run successfully.So far everything was fine. But when i try to make a connection inside NetBeans by using the code below i got the following exception.
Any help will be greatly appreciated. Urgent.

Each project in Netbeans has its own classpath, or build path, or whatever Netbeans calls it. Netbeans doesn't use the CLASSPATH environment variable.
