Bug 80767 – ebuild to provide Java Kernel Support

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Joël 2005-02-04 12:17:55 UTC]

Here's an ebuild for native java execution support.

You can run jar and class files directly, after doing a simple chmod +x.

The code is taken from http://www.linuxhq.com/java.html.

A patch from myself is applied upon emerging, which provides improved JAR execution, and fixes handling of pathnames that include spaces.

For this ebuild to be useful, you should add the following to /etc/conf.d/local.start:

echo ':Java:M::\xca\xfe\xba\xbe::/usr/bin/javawrapper:' >/proc/sys/fs/binfmt_misc/register
echo ':ExecutableJAR:E::jar::/usr/bin/jarwrapper:' >/proc/sys/fs/binfmt_misc/register

Have fun, and don't forget to post your improvements here !

Create a files/ subdirectory, and unpack this .tar.bz2 into it.

This ebuild needs major work before it can be added to the tree. I will be looking into it at this seems quite fun.

[Comment 4 Petteri Räty (RETIRED) 2005-04-24 04:00:57 UTC]

I will be working on the ebuild in the experimental tree:
https://gentooexperimental.org/svn/java/gentoo-java-experimental/dev-java/java-kernel-support/

The files probably need to be distributed as a separate tarball and it's better to write an init script than telling people to put stuff in local.start.

Hi Petteri,

I'm glad that my modest contribution may help :-)

- Your init.d script idea seems great, I hadn't thought of it
- Would it be better, in your opinion to package the vanilla "linuxhq.com" files into a tar.bz2, or to patch them beforehand ?

Please tell me if you want me to do the init.d script (I have some spare time here and there)

Thanks again,

Jo

If you want to write the init script, go ahead. Usually we download the tarball from upstream as it is, but now that there isn't an upstream tarball available I think we can just package the patched version. But probably best to ask for comments from java devs.

The tarball.

The tarball is now in the experimental tree.

[Comment 10 Petteri Räty (RETIRED) 2005-04-25 08:00:43 UTC]

The files are now patched in the tarball and the tarball will be uploaded to the gentoo mirrors if/when we release this to the public.

New version of the tarball - improved jar support with manifest detection

New ebuild version (note: I also added unzip dependency)

NOTE: should I use "java-config -J", or is it okay to just run "java" ?

[Comment 13 Joël 2006-07-16 02:32:07 UTC]

Petteri,

I'm willing to help and make an init script for java-kervel-support, but I don't know if it's possible to remove a binfmt_misc registration in the kernel once it's done.

[Comment 14 Josh Nichols (RETIRED) 2006-07-16 07:40:02 UTC]

Assuming you're using the new Java system, it is sufficient to just use java.

New Location seems to be:

http://overlays.gentoo.org/proj/java/browser/java-overlay/dev-java/java-kernel-support

Adding proper KEYWORD

[Comment 16 Andreas Sturmlechner 2015-08-07 21:25:19 UTC]

Ebuild removed from overlay, domain dead since 1999.
