Help needed regarding getting jnlp

Question

Hi all,
we need help regading java web start. We are downloadng some set of jar files to the client side using JNLP. With these jar files jnlp launches a swing base application in the client side and interacts with server application depoyed in WebSphere. In order to launch this application IBM Jre is needed in the client side. But IBM Jre can not install in non IBM meachines. So, we planing to make jar file of Jre and download it along with the rest of the jar files. After that we want to install in some directory in the client meachine and use that JRE to launch application. Now we are couple of problems with this approach.
1) To extract the Jre from the jar file we need the path, where these jars are downloaded.Even though we know the path "C:\Documents and Settings\Administrator\Application Data\IBM\Java\Deployment\cache" we can't hard code this, because user may change this location. The extraction program of this jar file in the client side is in one of the jar file that is downloaded. But here in the it is not able to recongnize relative path. So what we need is, is there any api to get this location of this path.
2)Second, In order to launch the application with downloaded Jre we need to set the classpath for jars that are downlaoded with Jnlp. But after downloading these jar files to the client side they are renamed(prefixed with RM and RT). Now, how to set the classpath to these jar files.
Here instead of JNLP if we use applet our problem will be solved. But we can't use applet because of client requirements.
Anybody, please try to suggest me some thing with this problem.
thanks,
