Hi,


I wanna know how can I install a JRE in Fedora 10...

Here is what I do...I download "jre 1.3.1-11" from SUN...and put this JRE under /root directory...and rpm the JRE.  Then, I link the like this "ln -s /root/j*.3.*/plugin/i386/ns600/libjavaplugin_oji.so /usr/lib/mozilla/plugins/libjavaplugin.so"
And put a few lines into /etc/profile
if ! echo $PATH | /bin/grep -q "/usr/java/j*.3.*/bin"; then
  PATH="$PATH:/usr/java/j*.3.*/bin"
fi

and save /etc/profile...then execute it.

However, I tried to open a web site with some java plugin stuff, but the plugin part didn't show at all...so what should I do?
How exactly I know my JRE is installed and run???  Help please~~

Hi xenia27,
write
which java
to se what the path is to your version of java.
Dont think is a good idea to have the jre in /root/
try moving it to /usr/local/
and remake the path and link.

And don't place wildcards in the path.

If you look at the plugins page (Help->plugins), do you see the java plugin there?

First of all I think you need a later version of the JRE (1.4.x). I don't remember 1.3.1 having a libjavaplugin built with Gcc 3.2, which is needed for Mozilla on Fedora. With an updated JRE installed you'll need t create a symlink like:

ln -s /path-to/j2re-1.4.2/plugin/i386/ns610-gcc32/libjavaplugin_oji.so /usr/lib/mozilla/plugins/libjavaplugin.so

It shouldn't matter as long as the JRE is a later version than 1.3.1. Have you tried to run the progam under 1.4.2? And if it failed what was the error.

You can actually have multiple java environment installed (but perhaps just one "active" in the browser), if the java program in question isn't "browserbased" it's just a question of the correct PATH etc....
