So it looks like there are three Java here:

This means the Java you're using with that plugin is
/usr/java/jre1.6.0_27, which should be a fairly recent Sun Java.

It may not be the final location (could be a symlink), but...

Indicates the Java in your path is GCJ (Gnu Java if you like).

This is, I think, an earlier and different install of Sun Java to the
one above. Which would explain why it may not have the new-style
mozilla plugin. Whatever you do don't remove this one as it's the one
you're relying on for banking.

Indicates the /usr/java/jre1.6.0_27 Java is broken. I think getting
the icedtea plugin working as Deepak suggests is probably your best
bet. This actually means you'll have 4 Java installed, but that
shouldn't be a problem. Next best solution is retry the installation
for /usr/java/jre1.6.0_27 and make sure you didn't miss anything out,
the plugin is failing because the Java in that location is broken.
