LoadPlugin: failed to initialize shared library /usr/local/java/jre/plugin/ns610
/libjavaplugin_oji.so [/usr/local/java/jre/plugin/ns610/libjavaplugin_oji.so: ca
nnot open shared object file: No such file or directory]

what happen

Looks like it's pointing to the wrong location? Try:
ls -l /usr/local/java/jre/plugin/ns610/libjavaplugin_oji.so

And see if anything is there, if not, modify the path and fix the listing you've got.
