BasicService showDocument problem

My application uses HTML for its help pages, and loads them into the local system's web browser with the following code:

BasicService bs = (BasicService)ServiceManager.lookup("javax.jnlp.BasicService");

bs.showDocument(this.getClass().getClassLoader().getResource("<path>/UserGuide.html"));

The resultant URL is something along the lines of:

jar:file:<Java Web Start>/.javaws/cache/http/<address, port>/DMDeploy/RMplanner.jar!/<path>/UserGuide.html>

This works great with Netscape 6.1, but loading the HTML file directly from the jar fails with Internet Explorer 5+ and Opera 5+.

This is far from being browser-independant, so is of little use. Is there any way of loading these files into any browser?

Thanks in advance, Martin.
