i do not know if this is the right forum for answering your question? but you need the J2EE platform. follow the instructions and get your J2EE enviroment going. this enviroment is only a reference implementation and i am not sure what it can do. But you will be able to create topics and messages queues with this minimum setup. Works for both Solaris and NT/Win 2000. Also get some sample code from Sun to get working code you can use for your project.
