@Bunyamın On the client (frontend) side, you won't be able to use these jars. On the server-side it should work without any problems - as far as I understand, you tried to use them client-side: but jars can not be translated into AJAX up to now.

@Bunyamın I'm not sure how or where you want to use this in your project: If you are trying to use this on the "client-side", the Google App Engine will prevent this library from working, since it is not supported as far as I know. If you are trying to use it as an servlet, you must additionally add the servlet to your web.xml. Please feel free to contact me again, if this does not help you.

Thank you for your answer. I had to change my core classes such that I can use just the emulated objects.
