java in firefox and jnlp launch - help needed.

[Wojciech Puchar]

i don't normally use java but have to for starting server remote 
management.

i use firefox and installed icedtea-web.

this page

https://www.java.com/en/download/installed.jsp

executes icedtea plugin and shows java is working properly.

Now i want to start remote console. it downloads launch.jnlp file.

i tried to run it with itweb-javaws and after loading software i'm getting

no iKVM64 in java.library.path


any idea? Thanks
