My understanding is that the most efficient way to use Java on AMD64 at present is:
Konqueror + blackdown's JVM plugin, and Sun's java-bin JRE/JDK for everything else. I don't think there's an easy way to get it working in Firefox unless you use the 32-bit firefox-bin. Is this accurate? |

Yup. If you want to use something besides Blackdown for a browser plugin, you'll have to use the existing 32-bit Java packages together with a 32-bit browser like firefox-bin. You can blame upstream for 1) not releasing 64-bit Java versions (Sun, IBM) and 2) for not providing security fixes for the 64-bit Blackdown.

|
|
Hello gentooers,
I haven't managed yet to get the java plug-in working on firefox. The farthest I managed to go when I test it at http://www.java.com/en/download/help/testvm.xml, is to get a gray box with a red cross on the topleft corner (which is still better than just getting the "missing plug-in" icon). If I open the java console from that box, I get :
| Code: | Java(TM) Plug-in: Version 1.4.2
Using JRE version 1.4.2-03 Java HotSpot(TM) 64-Bit Server VM
[...]
java.lang.UnsupportedClassVersionError: testvmDynamicJavaCom (Unsupported major.minor version 49.0) |
I tried to follow http://gentoo-wiki.com/HOWTO_Install_firefox_with_java_on_amd64, but I guess I'm missing something.
Relevant packages installed :
www-client/mozilla-firefox-2.0.0.8
www-client/mozilla-firefox-bin-2.0.0.4 (same problems)
dev-java/blackdown-jre-1.4.2.03-r14
dev-java/blackdown-jdk-1.4.2.03-r15
dev-java/sun-jre-bin-1.6.0.03
app-emulation/emul-linux-x86-java-1.6.0.03
This is the combination that gets me the farthest:
| Code: | | lrwxrwxrwx 1 root root 73 2007-11-12 13:03 /usr/lib/mozilla-firefox/plugins/libjavaplugin_oji.so -> /opt/blackdown-jdk-1.4.2.03/jre/plugin/amd64/mozilla/libjavaplugin_oji.so |
| Code: | # java-config -L
The following VMs are available for generation-2:
*) Blackdown JDK 1.4.2.03 [blackdown-jdk-1.4.2]
2) Blackdown JRE 1.4.2.03 [blackdown-jre-1.4.2]
3) Sun 32bit JRE 1.6.0.03 [emul-linux-x86-java-1.6]
4) Sun JRE 1.6.0.03 [sun-jre-bin-1.6] |
Same thing with Blackdown JRE and symlinking to /opt/blackdown-jre-1.4.2.03, and I can't find the java plug-in in /opt/sun-jre-bin-1.6.0.03/ anymore (the nsplugin USE flag doesn't seem to exist anymore for it?)
Anything else I can try? |

I'm having the same problem as you.
Check out this thread: FireFox and Java problem
I have made progress from it, and I only need to figure out how to eselect the java plugin now.
Just to make sure we're on the same page:- Gentoo's Java Guide
| Gentoo Java guide wrote: | | Note: nsplugin is not available for all architectures. Check for available plugins on your arch before trying to install a VM by running emerge -pv <java-vm>. |
Particularly, the blackdown-jre-1.4.2.03 nsplugin cannot be used for amd64. It has been masked because of this security issue:
[ GLSA 200705-20 ] Blackdown Java: Applet privilege escalation
That said, I'm using the sun-jdk-1.6 VM.
1.6 >= 1.4.2.03-r14 and is unaffected by the bug.
So it is safe to unmask the nsplugin USE flag for that package locally.
To do that I created the file /etc/portage/profile/package.use.mask and added `dev-java/sun-jdk -nsplugin` (without the backquotes)
Then I re-emerged the VM:
| Code: | | # emerge -Dva "dev-java/sun-jdk" |
Now I still have to set a java browser plugin:
| Code: | # eselect java-nsplugin show
Current Java browser plugin
(unset) |
But I'm stuck on how to set the sun-jdk-1.6 because this is the list I see:
| Code: | eselect java-nsplugin list
Available 32-bit Java browser plugins
Available 64-bit Java browser plugins |
...when it's actually supposed to look like this:
| Gentoo Java guide wrote: | # eselect java-nsplugin list
[1] sun-jre-bin-1.5
[2] blackdown-jre-1.4.2 |
...and java-config complains when I try to force it through
| Code: | # eselect java-nsplugin set 64bit sun-jdk-1.6
!!! Error: Expected "/usr/share/java-config-2/nsplugin/sun-jre-bin-javaplugin.so" to exist, but it doesn't.
!!! Error: Perhaps "sun-jdk-1.6" isn't a valid name of VM built with nsplugin?
|
| Code: | # eselect java-nsplugin set 32bit sun-jdk-1.6
!!! Error: Expected "/usr/share/java-config-2/nsplugin/sun-jre-bin-javaplugin.so" to exist, but it doesn't.

On a 64bit system, sun-jdk does not provide a nsplugin.
The plugin for 32bit is in emul-linux-x86-java
| Code: | $ equery uses emul-linux-x86-java|grep nsplugin
+nsplugin |
But that of course only works in 32bit browsers like firefox-bin or opera.

Again, that output is from a 32bit system.

See above.
Speaking of which...
what's the process on Gentoo getting IcedTea merged in the tree?
We definately need IcedTea on Gentoo. Fedora 8 comes with a working 64bit java plugin from openjdk/classpath fusion ootb. So does Ubuntu.

I would _love_ a working 64 bit java plugin
Let me know if there is some way I could help to get that in portage |

Generally to check if any ebuilds are being worked on, do this
Following those I couldn't find an existing ebuild
You can help develop an overlay
Check IRC channel #gentoo-dev-help on FreeNode for guidance
I've never helped development though 
I'm still working on getting LPI certified before I try |

Just noticed that there's a "java-gcj" overlay.
I'm emerging gcj with the nsplugin and gconf USE flags right now. Will let you guys know how I go. |

| Yeah, no luck. My browser doesn't crash, I just get a grey box on pages where there's an applet. Disappointing. |

the olny overlay you need is on you computer, just upgrade gcc to 4.2 and compile it with the gcj flag, get the ebuild for the svn, put it in your overlay and emerge it.
