"Sri Sri",
Welcome to the JavaRanch. We don't have many rules here, but we do insist that you use you Real Name and not some sort of "handle" or obvious alias. If you're not sure about this, see

I can't say specifically about your problem, since I'm not familiar. The one thing that you do need to determine, however, is whether the java4ever solution is designed to run in a JME environment. The JME core classes don't have all the methods and capabilities that the full JRE definition provides, so if a class was coded to use those missing methods or objects, it won't work in a JME JVM.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
