plugin does not function and not compile

Hello,

I have a Linux machine and I use Netscape 7.1 which I upgraded from Mozilla.

I downloaded j2sdj-1.4.2_02 and I have installed the plugins as followes:

in .mozilla/plugins- directory a link to :

edward@linux:~/.mozilla/plugins> ls -l
totaal 0
lrwxrwxrwx 1 root root 72 2003-11-25 23:23
libjavaplugin_o ji.so ->
/usr/java/j2sdk1.4.2_02/jre/plugin/i386/ns610-gcc32/libjavaplugin_o ji.so
edward@linux:~/.mozilla/plugins>

Also in the "About Plugins" in Netscape I see all my plugins, however
the plugins do not function when loading/showing a page!!

This problem did not always exist, and I suspect Netscape 7.1.

However, how is it possible that "About Plugins" show the plugins !! but
they do not function:

Java(TM) Plug-in 1.4.2_02-b03

File name: libjavaplugin_o ji.so
Java(TM) Plug-in 1.4.2_02

=============== =============== =============== =============== =============== =============== ==========

Also I can not compile Aplets although normal java and
Swing-programs I can compile, no problem.

To 'see' javac and java I have to add to my $PATH
/usr/java.j2sdk1.4.2 _02/bin

Error when compiling:
edward@linux:~/java> javac Simple.java
Note: Simple.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.


My questions:
- Is the dis-functioning of the plugins and the
not-being-able-to-compile-plugins related? (I think not, only
coincidence, but I am just working with Java for 1 week now so knowledge
is lacking here!)

- How can I solve those problems, should there be added more directories
to the path in order to be able to compile?

Thanks in advance, Edward Hage
