No java in firefox

[Atle]

Hello all!

I have no java working in firefox, and there is no java listed among the plugins. I do have NPAPI Plugins Wrapper 1.0.0 and Shockwave Flash is "working". I think this indicates 32 bit plugins are installed and working.

Following is all the relevant system information I could think of...

# emerge -1pv nspluginwrapper
...
[ebuild R ] net-www/nspluginwrapper-1.0.0 0 kB
...

# emerge -1pv www-client/mozilla-firefox
[ebuild R ] www-client/mozilla-firefox-3.0.3 USE="dbus ipv6 java mozdevelop startup-notification xulrunner -bindist -custom-optimization -gnome -iceweasel -restrict-javascript" LINGUAS="..." 0 kB

$ eselect java-nsplugin list
Available 32-bit Java browser plugins
[1] emul-linux-x86-java-1.6 current
Available 64-bit Java browser plugins

$ java-config --list-available-vms
The following VMs are available for generation-2:
1) Blackdown JDK 1.4.2.03 [blackdown-jdk-1.4.2]
2) Sun 32bit JRE 1.6.0.07 [emul-linux-x86-java-1.6]
*) Sun JDK 1.6.0.07 [sun-jdk-1.6]

$ eselect java-vm list
Available Java Virtual Machines:
[1] blackdown-jdk-1.4.2
[2] emul-linux-x86-java-1.6 system-vm user-vm
[3] sun-jdk-1.6

$ java-check-environment
....
* Java environment is sane. Congratulations!

# emerge -1pv app-emulation/emul-linux-x86-java
[ebuild R ] app-emulation/emul-linux-x86-java-1.6.0.07 USE="X alsa nsplugin" 0 kB

----------------------
Well, that was all the information I could think of. All looks sane to me, but no plugin in firefox.

Any suggestions?

The only java plugin for 64bit firefox is icedtea. It's in the Java overlay.

Just so that it is explicit, a 32bit plugin and a wrapper, like for flash, won't work then?

[loftwyr]

nspluginwrapper won't handle java.

If you want 32-bit plugins, you have to run firefox-bin.

Does it work? What is your experience?

works like a charm!

Ok. I installed openjdk-bin-1.6 but none of the java programs compile with it. for example gjdoc/antlr etc. fail to emerge. Does this mean that I need to keep sun-jdk around as well? How many JDK's do I need for a working Linux system...

Does anybody what this error is about:

What I notice is that although I selected openjdk-bin as my system VM, it still used sun-jdk for java:

Code: Select all

GENTOO_VM=sun-jdk-1.6  CLASSPATH="" JAVA_HOME="/opt/sun-jdk-1.6.0.10"
JAVACFLAGS="-source 1.4 -target 1.4" COMPILER=""
and of course, the output of emerge --info

Second thing I notice is that if I force the VM in the ebuild, it still doesn't work. What makes it work is adding "-J-Xmx512m" to javac.

So, the questions are:
1. why does gjdoc not use the system wide VM for above variables?
2. Why does it need that "-J-Xmx512m" flag in javac? What is the safest way to pass that flag universally?

Does anybody know? We can get rid of sun-jdk if these problems are resolved.

So, the questions are:
1. why does gjdoc not use the system wide VM for above variables?

It seems like it picks virtual/jre and that's mapped to sun-jdk or ibm-jdk-bin. I just put it in overlay and added openjdk-bin to that list. Once I removed sun-jdk, gjdoc started picking openjdk-bin as its JRE.

2. Why does it need that "-J-Xmx512m" flag in javac? What is the safest way to pass that flag universally?

I did not find anything for this. So,

Code: Select all

cd /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/bin
mv javac javac.bin

and created javac with:

Code: Select all

#!/bin/sh
${0}.bin -J-Xmx512m "$@"

Problem solved. One JDK less. 130MB gone. Now onto the emul stuff.

[devsk]

Why is openjdk-bin not in portage? Other distros have it as a standard package. It should be included and virtual/jdk modified accordingly.

So far, all packages have compiled fine with openjdk-bin java.
