= JPackage Java for Fedora =
For Fedora 7 onwards, this article is superseded by SunJava5OnFedora and SunJava6OnFedora.
Here are step-by-step instructions for building Java packages from [[http://jpackage.org|jpackage.org]] for Fedora 8 based on the Java Package Recommendations in the [[http://fedora.redhat.com/docs/release-notes/fc4/errata/|Fedora Core 4 Release Notes]]:
'''6.1.8. Java Package Recommendations'''
''Fedora Core 4 users are advised not to use the Java RPM provided by Sun. It contains Provides that conflict with names used in packages provided as part of Fedora Core 4. Because of this, Sun Java might disappear from an installed system during package upgrade operations. Fedora Core 4 users should use either the RPM from jpackage.org or manually install the Sun Java tarball into /opt. Sun Java 1.5+ is recommended for stability purposes.''
{i} The quote above is from the Fedora Core 4 release notes but the same issues affect later releases too. The steps shown in this guide are tested on Fedora 8 (i386) but the same process works on other releases.
For the ''x86_64'' architecture, download the `x86_64` file instead of the `i586` file from the Sun website.
These instructions should also work for similar distributions such as CentOS.
Note that Red Hat Enterprise Linux includes pre-built binary packages for Sun java,
which are available in separate channels (e.g. the ''RHEL Supplementary'' channel
for RHEL 5).
== Create RPM Build Environment ==
If you have not built RPM packages using your regular user account (not root) before, you should
[[CreateRPMBuildEnvironment|create an RPM build environment]] for your account before going any further.
== Install jpackage.repo from JPackage ==
{i} This step is optional.
The rest of the procedure will work without configuring the [[http://jpackage.org/|JPackage]] repository,
but it may be worth doing this because it gives you access, via `yum` or a GUI package manager built on `yum` such as `yumex`, to a large number of nicely-packaged Java applications to go with your Java installation.
However, bear in mind the following caution from the
[[http://fedora.redhat.com/docs/release-notes/fc5/release-notes-ISO/|Fedora Core 5 Release Notes]]:
'''15.2. Fedora and the JPackage Java Packages'''<
>
Fedora Core includes many packages derived from the JPackage Project, which provides a Java software repository. These packages have been modified in Fedora to remove proprietary software dependencies and to make use of GCJ's ahead-of-time compilation feature. Fedora users should use the Fedora repositories for updates to these packages, and may use the JPackage repository for packages not provided by Fedora.
Refer to the JPackage website at http://jpackage.org for more information on the project and the software that it provides.
|| /!\ '''Mixing Packages from Fedora and JPackage'''<
><
>Research package compatibility before you install software from both the Fedora and JPackage repositories on the same system. Incompatible packages may cause complex issues.||

== Build Java RPM Packages ==
For Fedora 7 and later releases, some edits are needed to the RPM spec file to fix some outdated
directory locations. The same edits are needed for CentOS 5 too.
* Unpack the RPM:
. {{{
[localhost download]$ rpm -Uvh java-1.5.0-sun-1.5.0.14-1jpp.nosrc.rpm
}}}
* Edit `~/rpmbuild/SPECS/java-1.5.0-sun.spec` and change the two lines:
. {{{
%define x11bindir %{_prefix}/X11R6/bin
%define x11encdir %{_prefix}/X11R6/lib/X11/fonts/encodings
}}}
. to:
. {{{
%define x11bindir %{_prefix}/bin
%define x11encdir %{_prefix}/share/X11/fonts/encodings
}}}
* Rebuild `java-1.5.0-sun-1.5.0.14-1jpp.nosrc.rpm` with the edits:
. {{{
[localhost download]$ rpmbuild -bs ~/rpmbuild/SPECS/java-1.5.0-sun.spec

If you've installed `java-1.5.0-sun-plugin` and you want to use it with Firefox or any other mozilla-based browser,
you'll need to set up the link manually as there is a small bug in the

== Java Web Start ==
The Java Web Start binary - `javaws` - is included in the `java-1.5.0-sun-devel` package, but for reasons I have not yet fathomed, is not one of the binaries handled by the alternatives system in the JPackage RPMs. So if you need to use `javaws`,
you'll need to set it up manually.
{{{
$ sudo /usr/sbin/alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/java-1.5.0-sun-1.5.0.14/jre/bin/javaws 1
}}}
You'll also want to register the MIME type `application/x-java-jnlp-file` with the binary `/usr/bin/javaws` in your browser. How you do this is browser-specific.
For example, in Firefox you can browse to a URL of that type such as the
[[http://dist.trolltech.com/developer/download/webstart/qtjambi.jnlp|Qt Jambi web demo]] and when prompted for which helper application to use to open the file, select
"Other" and then select `/usr/bin/javaws` from the file chooser that appears.
