I downloaded

      JDK 6 Update 7

/The Java SE Development Kit (JDK) includes the Java Runtime Environment 
(JRE) and command-line development tools that are useful for developing 
applets and applications.

/from the SUN site.

I went through the motions, executing the ....*.rpm.bin inder /usr/java,
created symlinks ( both in ---/.mozilla/plugins and 
(to be sure)  /usr/lib/mozilla/plugins.

Still no effect. And the funny thing is:
about:plugins now report this:

    Java(TM) Plug-in 1.6.0_06-b02

    File name:
    Java(TM) Plug-in 1.6.0_06

I was expecting  _07, not _07 if the last 2 digits identify the update 

I also have:

    GCJ Web Browser Plugin (using IcedTea) 1.2

    File name:
    The GCJ Web Browser Plugin (using IcedTea) executes Java applets.

I do not mind living on the edge as long as I manage to bring up the 
in question.Could it be that openjdk runs the whole show so that it does 
not matter what softlinks I enter? I.e. they don't take effect because 
openjdk tries to  do the job and fails - and that's it?
Where do I find such experimental plugins? Is it just to replace the old 
one by a new one
wherever it is installed?
