Which version of Java with 64-bit Programs?

[ctlmd]

I've been trying to get a Java runtime environment to work with my Fedora 4_64 and 64-bit browsers, but no plugins seem to work, even the AMD64 version. What am I doing wrong? :confused:

[mrhoyt4]

Did you copy the browser plugin in the jre to the browser you want to use? The plugin is located in the jre/plugins/arch and copy it to the plugin directory for you web browser.

[ctlmd]

I made a symbolic link, while in the Mozilla plugins directory ln -s /location/of/java/plugins/nameofjavaplugin.so because that is the only way it has worked for me in the past, and I'm told it crashes if you just copy it directly into the directory.

I don't think there is a 64bit javaplugin from Sun. For that, I'm using blackdown java and the plugin works fine...

jeff@speedy ~ $ java-config --list-available-vms
[sun-jdk-1.5.0.03] "Sun JDK 1.5.0.03" (/etc/env.d/java/20sun-jdk-1.5.0.03)
[blackdown-jre-1.4.2.02] "Blackdown JRE 1.4.2.02" (/etc/env.d/java/20blackdown-jre-1.4.2.02)
[blackdown-jdk-1.4.2.02] "Blackdown JDK 1.4.2.02" (/etc/env.d/java/20blackdown-jdk-1.4.2.02) *


jeff@speedy ~ $ ls -l /usr/lib/MozillaFirefox/plugins/javaplugin.so
lrwxrwxrwx 1 root root 69 Jun 20 13:44 /usr/lib/MozillaFirefox/plugins/javaplugin.so -> /opt/blackdown-jre-1.4.2.02/plugin/amd64/mozilla/libjavaplugin_oji.so

[ctlmd]

I made an initial attempt at what would normally work for installing the Blackdown j2re1.4.2-01-linux-amd64, by just downloading the j2re1.4.2-01-linux-amd64.bin, chmod 755, ./ extracting/running it, and then linking the plugin to the Mozilla file, and that didn't work.

I'm not sure what files I need to download before running the code below. If you could make a few clarifications it would be appreciated:
What do the brackets and quotations indicate? for instance
and the rwxrwx

jeff@speedy ~ $ java-config --list-available-vms
[sun-jdk-1.5.0.03] "Sun JDK 1.5.0.03" (/etc/env.d/java/20sun-jdk-1.5.0.03)
[blackdown-jre-1.4.2.02] "Blackdown JRE 1.4.2.02" (/etc/env.d/java/20blackdown-jre-1.4.2.02)
[blackdown-jdk-1.4.2.02] "Blackdown JDK 1.4.2.02" (/etc/env.d/java/20blackdown-jdk-1.4.2.02) *


jeff@speedy ~ $ ls -l /usr/lib/MozillaFirefox/plugins/javaplugin.so
lrwxrwxrwx 1 root root 69 Jun 20 13:44 /usr/lib/MozillaFirefox/plugins/javaplugin.so -> /opt/blackdown-jre-1.4.2.02/plugin/amd64/mozilla/libjavaplugin_oji.so

I knew that was a bad idea...
java-config is a gentoo utility I used to show which vm's I have. Of course sun-jdk-1.5.0.03 has no java plugin at all, but blackdown does, and it works for me. Is your browser 32 bit or 64 bit?
rwxrwx is the permissions on my javaplugin.

[ctlmd]

I think both Mozilla and Firefox are 32-bit running under x86_64, if that's possible. The entire listings in the Help > about Mozilla/Firefox are:

Mozilla 1.7.8
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.7.8-2

and

Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4


p.s. If that's true, can I get 64-bit versions?

[je_fro]

It looks to me like you'll need to use the 64bit java plugin. I don't recall where to put it in FC4, but perhaps someone will come along and enlighten us...
