how to accessing java ?

Hi all ,

I currently have some Java classes. Instead of converting them to
Javascript, I am exploring of using Java XPCOM or Liveconnect to connect js
and java into a firefox extension.

 However, I find some news about Liveconnect is not longer going with
firefox 3.6 , is it true ?

 

And anyone knows what's the difference about javaxpcom and liveconnect ? if
you have any suggestion about develop java in firefox extension  , please
let me know!

 

 

Any help will be appreciated,

Thanks,

Andrew
