Please see How does VAJ handle compile time and runtime classpath? How do I specify the classpath and/or use third-party libraries in VAJ? for details on using third-party libraries in VAJ. You will most likely have to import at least part of the JARs in order to get your code to compile. The JARs can be added to the runtime classpath described in that FAQ to get the rest of the classes.

As for the java.security file, I would speculate that VAJ's VM has the same file somewhere, too. I'm not familiar with JCE, so I can't say exactly where VAJ might try to locate it, but you can try just searching under you VAJ installation for an existing version. Where does the JCE documentation tell you to put it? Can you set a system property instead of adding a line to the java.security file?
