Connecting to Derby database

Question

Well I switched over from Notepad++ to Netbeans to simplify the GUI processes. And of course by simplify I mean almost eliminate. In any case now that the basic underlying information needs have been identified and I have a GUI, the next step is an appropriate database for said information. However I am having some issues creating and connecting to the Derby database.
I have already gone to Tools > Libraries > New Library, "JavaDBEmbedded" with the following classpath and Javadoc. All is good so far.
C:\Sun\sdk\javadb\lib\derby.jar
C:\Sun\sdk\javadb\javadocI used the following statement(s) to load the driver. I tried this both within the class and a method for a button. Within the method the first try is fine, however I am still getting an error for the second try.
private void jButtonCreateActionPerformed(java.awt.event.ActionEvent evt) {                                             
//Create the database below
//Load the following driver
try {Class.forName("org.apache.derby.jdbc.EmbeddedDriver");}
catch (Exception driver) {}
try {Connection dbConnection = DriverManager.getConnection("jdbc:derby:Map1;create=true", "Username", "Password");}
catch (ClassNotFoundException ex) {ex.printStackTrace();}
//Create the database above
}Driver Manager doesnt strike me as a variable. Which is saying to me its trying to set one variable equal to another. Which means there is a problem creating a new instance of the "Connection" class?? Is there something I need to import to use the connection class?

It's a class that provides a static factory method called getConnection that returns a java.sql.Connection for some given parameters. You can find more information about the Driver Manager class (and the getConnection() methods in particular) here. You need to import java.sql.DriverManager and java.sql.Connection.
