I'm not sure how to add items to the class path from JCreator (or even if you can), but you can package the library with your program for easy distribution and use. Simply put all the files from the Java Media Framework download into the startup folder of your java application (I think by default this is the folder where all the .class files are, but it could very well be different, like I know in Eclipse that the startup folder is the base project folder).
Alternatively, other editors have tools that manage the classpath for you (such as Eclipse and NetBeans), so for example, in Eclipse you just need to add an external library and it will automatically compile and run with the classpath set correctly for you.
