Somehow the assiciation in my Vista registry for .jnlp files got broken.  When I try to open a .jnlp I get a message that Windows does not recognize this file type.  I have uninstalled and reinstalled my Java runtime and the Sun checker says I have a good up to date installation.

Any suggestions?

Thanks much

Thank you CEHJ.  Very nice to be able to see what the associatins are.  I will accept that as the solution.

MORE INFO ON jnlp:

After some digging, I found that the proper association for jnlp is javaws.exe, found on my machine in C:\Program Files\Java\<java release>\bin.

Setting an association on Vista is a bit more of a pain than on XP, but if you have a Foo.jnlp and you open it, there is an option to browse for the progam to open it.
