<toc>
<chapt>Introduction
<p>
<sect>Introduction to this FAQ
<P>This FAQ was started by Javier Fernández-Sanguino who on
February 1st, 2000 was enough to send a message to the debian-java
mailing list with the subject "How about a Debian-Java-FAQ?". Of
course, since "every idea is a responsibility" he had to do this himself
looking through the three month-long archive of the newborn mailing list.
<p>The purpose of this FAQ is to be a place to look for all kinds of
questions a developer or user might have regarding Java as far as Debian
is concerned. It includes license issues, development packages available,
and programs related to building a Free Software Java environment.
<p>Thanks go to all the (many) contributors from the debian-java mailing list,
who have made this document possible. Without their knowledge this
FAQ would not be at all possible since I only have a vague knowledge
of what they're talking about when I browse the list.
<p>Special thanks go to Paul Reavis, whose previous Debian-JDK
informational page I used to add more information, and who made useful
suggestions to this document. Also to Peter Moulder who revised
thoroughly the FAQ and provided many suggestions, to Juergen
Kreileder, maintainer of Blackdown's debian packages who pointed out
some mistakes, and to Egon Willighagen, who has provided quite a lot
of proper patches to update its content.
<p>This document does not address issues with other Linux
distributions, or with non-Debian-specific problems.
<sect>Location of this FAQ
<p>This FAQ is published under the Debian Documentation Project
at <url id="http://www.debian.org/doc/manuals/debian-java-faq/">.
The <package>java-common</package> (available at
<url id="http://packages.debian.org/java-common">) provides an
HTML version for offline reading. The package version does not provide Text and
PDF versions currently (if you want them please submit a bug
'wishlist' to the package). Also, the web version might be more up-to-date
than the package's offline version.
<sect id="bugs">Sending bugs on this FAQ
<P>Please note that this FAQ is still outdated but gets updated step by step.
<p> Please file bug reports against the java-common package if you find errors
or have suggestions on how to improve this document. However, make sure you
have read the latest online version of the english text available at <url
id="http://www.debian.org/doc/manuals/debian-java-faq/index.html"> before
filing a bug report. Translations, if available, and the offline version in
the java-common package might be out of date.
<sect>What is Java?
<p>
Java is a programming language originally developed by James Gosling at
Sun Microsystems (which is now a subsidiary of Oracle Corporation) and
released in 1995 as a core component of Sun Microsystems' Java platform.
Since May 2007, Sun/Oracle with some partners like Red Hat provide a free
implementation released under the GNU GPL called OpenJDK.
More information can be found at <url
id="http://en.wikipedia.org/wiki/Java_%28programming_language%29"
name="Wikipedia">.
<sect>Where can I ask questions about Java on Debian?
<p>The appropriate place to ask such questions is <email>debian-java
at lists.debian.org</email>. You can subscribe at the <url
id="http://lists.debian.org/debian-java/" name="Debian Mailing Lists"> page.
<sect id="moreinfo">Complementary information
<p>Users might want to access some online sources to complement the
information available in this FAQ which might be, sometimes, too out
of date. The main source of information is the
<url id="http://wiki.debian.org/Java" name="Java entry"> at the Debian's wiki.
<p>Since Ubuntu is based on Debian, some users might find it helpful
to check the tips on <url id="https://help.ubuntu.com/community/Java"
name="Installing Java"> on Ubuntu's wiki.
<sect id="pending">Uncovered issues
<p>This FAQ does not describe some issues due to lack of time and/or
information. If you are able to help in any of these, please, provide
them to the documentation maintainer:
<list>
<item>Information on how to setup a fully working Servlet engine (Application
Server) using Apache and Tomcat or information on how to setup non-free
application servers (such as WebSphere) in Debian.
<item>Specific information targeted for non-i386 users (PowerPC users and AMD64 users), some can be found in Ubuntu's wiki.
</list>
<chapt>Java Development
<p>
<sect>What full-fledged Java development platforms are available in Debian?
<p> If you are looking for an integrated, java virtual machine,
compiler and runtime environment Debian does provide them. Of course
that would depend on the Debian GNU/Linux version you are using,
generally speaking they would be:
<list>
<item>Sun's OpenJDK 6, available since the Debian 5.0 <em>Lenny</em>
release in the <em>main</em> section.
<item>Oracle's OpenJDK 7, available since the Debian 7.0 <em>Wheezy</em>
release in the <em>main</em> section.
<item>The combination GCJ, GIJ, and Classpath in the <em>main</em> section.
</list>
<p>It is recommended to install one of the default-jdk or default-jre meta
packages which either installs OpenJDK or GCJ depending on the architecture and
Debian version.
<sect id="free">What free platforms are there and how can I contribute?
<p>
Please help one of the Free Java implementations if you want to use Java
in Debian. There are a lot of projects that you can choose from:
<list>
<item>openjdk: <url id="http://openjdk.java.net/"></item>
<item>gcj and libgcj: <url id="http://gcc.gnu.org/java/"></item>
<item>Classpath <url id="http://www.classpath.org">. Most of the
Standard classes for Java 1.2 (except Swing and RMI) are implemented by
the ClassPath project, it tries to build an alternative to jdk's 1.2
core classes. (NB: This was removed from Squeeze)</item>
<item>Mauve <url
id="http://sources.redhat.com/mauve/"> is a free suite to test if
these tools are 'compliant'.</item>
</list>
<p>Most free Java development is grouped under the <url
id="http://www.gnu.org/software/java/" name="Free Java
Project">.
<sect id="license-concerns">Questions on platforms and license concerns
<sect1 id="java6">Java 6 and 7
<p>There are binary packages available for the Java 6 and Java 7 platforms
since the Debian 7.0 ('wheezy') release.
Once this is done and you have updated your package database. You can either
install the Java development kit:
<example>
apt-get install openjdk-6-jdk
</example>
or the Java runtime environment:
<example>
apt-get install openjdk-6-jre
</example>
<p>Similarly, you can install the Java 7 development kit:
<example>
apt-get install openjdk-7-jdk
</example>
or the Java 7 runtime environment:
<example>
apt-get install openjdk-7-jre
</example>
<p>You might want to update the alternatives system to have Sun's tools as the
default:
<example>
update-java-alternatives -s java-1.6.0-openjdk-amd64
</example>
Or for java 7:
<example>
update-java-alternatives -s java-1.7.0-openjdk-amd64
</example>
<sect1 id="openjdk">Oracle proprietary JVM
<p>Since the version 7 of the OpenJDK, the proprietary JVM developments are done on the OpenJDK. That means that the OpenJDK is strongly tested and high quality.
<p>However, some users might want to use the Oracle JVM for the proprietary extensions (for example: the browser plugin). For such need, Debian provides a tool called <url id="http://packages.debian.org/sid/java-package" name="java-package">. The program make-jpkg will take an upstream archive and convert it to a Debian package. For example:
<example>
make-jpkg jdk-6u31-linux-x64.bin
</example>
<p>For more information see <url id="http://www.oracle.com/technetwork/java/index.html" name="Oracle Technology Network Java">.
<sect>Making Debian packages for Java programs.
<sect1>Can the package go into main?
<p>Yes, <em>but only if</em> it can be build and run with Java programs/tools
in main, and if it has a Debian compliant open source license.
If it needs programs from contrib or non-free, then is <em>must</em>
go into contrib or non-free, depending on the license of the program itself.
<sect1>Is there a good example Debian package?
<p>There are many Debian packages of both Java applications and libraries.
These may serve as an good starting point, as it can serve as an example
for making a new Debian package.
<p>A good start would be to check out the pkg-java project on
Alioth: <url id="http://pkg-java.alioth.debian.org/">.
<p>Note that there are many ways to make a Debian package, making use
of Ant or Makefiles does not really matter.
But, some tips for good practice are given on the pkg-java page:
<url id="http://pkg-java.alioth.debian.org/developers.html#rules"> and
<url id="http://pkg-java.alioth.debian.org/building.html">.
<sect1>What tools are available to make maintaining a Java packages easier?
<p>Both cdbs and debhelper (dh7) have support for ant scripts. There
are also a number of specialized tools or build helpers. Have a look
at <package>javahelper</package>
or <package>maven-debian-helper</package>. <package>gcj-jdk</package>
also has a dh_javadoc tool.</p>
<sect1>Linking package Javadoc to system javadoc.
<p>The java-policy mandates that documentation must be linked with the
javadoc installed on the system. This can be done by passing javadoc
the "-link" argument or by using the &lt;link&gt; tag in ant. An
example:
<example>
# command line example of linking against system doc.
javadoc -link /usr/share/doc/default-jdk-doc/api [other arguments]
&lt;!-- Ant example of linking against system doc --&gt;
&lt;javadoc [attributes]&gt;
&lt;link href="/usr/share/doc/default-jdk-doc/api/" /&gt;
[other tags]
&lt;/javadoc&gt;
</example>
</p>
<p>The documentation must be installed at the time the linking is
done; so in the example cases above the package would need a
Build-Depends or a Build-Depends-Indep on
<package>default-jdk-doc</package>.
</p>
<p>
Here is a short list of packages that can be used for reference:
<list>
<item><package>commons-jci</package></item>
<item><package>ow-util-ant-tasks</package></item>
<item><package>libhamcrest-java</package></item>
<item><package>libfreemarker-java</package></item>
</list>
</p>
<chapt>Managing Java (for users and administrators)
<p>
By default Java programs shipped with Debian will use the java
in PATH. Some of them may respect the JAVA_HOME variable
(usually only if upstream supports this) or have command line
arguments to select a different java implementation.
</p>
<p>
Unfortunately not all java implementations work as well as others.
So some times it may be necessary to change the current java and
Debian provides an easy way to change the default java in PATH by
using update-java-alternatives (from the <package>java-common
</package>). Some examples of how to do this are:
</p>
<p>
<example>
# List available java implementations
$ update-java-alternatives --list
# Use openjdk-6
$ update-java-alternatives --set java-6-openjdk
# Use the non-free sun java.
$ update-java-alternatives --set java-6-sun
# Use the non-free sun java only for the web plugin
$ update-java-alternatives --plugin --set java-6-sun
</example>
</p>
<p>
For more information, please read the manpage (or the --help
output) of update-java-alternatives. Also please note that
update-java-alternatives is a frontend for update-alternatives.
</p>
<chapt>Java Virtual Machines (JVM)
<p>
<sect>What JVMs are available in Debian?
<p>The following JVMs are currently available in Debian Wheezy:
<list>
<item><package>openjdk-6-jre</package></item>
<item><package>openjdk-7-jre</package></item>
<item><package>gcj-4.7-jre</package></item>
</list>
</p>
<p>The following lists JVMs available in Debian 6.0 release ('Squeeze'):
<list>
<item><package>openjdk-6-jre</package></item>
<item><package>sun-java6-jre</package> (non-free)</item>
<item><package>gcj-4.4-jre</package></item>
</list>
<p>
<sect>What Java Compilers are available in Debian?
<p>
<list>
<item><package>openjdk-6-jdk</package></item>
<item><package>openjdk-7-jdk</package></item>
<item><package>gcj</package>. Compiles Java source to native code,
also source to bytecode, or bytecode to native code. Please note that the
support of the Java language is not completed.</item>
</list>
</p>
<sect>What API do these JVMs provide?
<p>Note that providing an API does not mean that everything is
implemented, and certainly not implemented correctly.
<sect>Are there known problems?
<p>Yes, there are. Some of these are reported as Debian bugs. You can
look up the bugs for a specific Debian package at the <url
id="http://www.debian.org/Bugs/" name="Debian Bug Tracking System">. As
a quick link, here are some packages:
<list>
<item><url id="http://bugs.debian.org/java-common" name="java-common"></item>
<item><url id="http://bugs.debian.org/src:openjdk-6" name="openjdk-6"></item>
<item><url id="http://bugs.debian.org/src:openjdk-7" name="openjdk-7"></item>
<item><url id="http://bugs.debian.org/src:gcj-4.7" name="gcj-4.7"></item>
</list>
<p>As common within the Debian project, the developers would
appreciate good bug reports on found problems. These include the good
description of the problem, the command that gives the problem, the
errors given when running the command, and any other information that
might be relevant. A good tool to report bugs is
<package>reportbug</package>.
<sect>How can I use the proprietary version of the JDK/JRE from Oracle as a Debian package?
<p>
The package <url id="http://packages.debian.org/wheezy/java-package/" name="java-package"> provides an easy way to convert an upstream installer into a Debian package. It should be as easy as:
<example>make-jpkg ~/Downloads/jdk-6u31-linux-x64.bin
</example>
<p>For more information, see this <url id="http://sylvestre.ledru.info/blog/2012/02/29/java_package_replacement_of_sun_java6" name="Blog article">
<sect>Do I need a JVM to run a Java program in Debian?
<p>
No, you can try to run the applications without a jvm by compiling
the source code to native code is. However, the usage of the OpenJDK is recommended. For example, gcj does not provide any support of Swing (the Java GUI API).
<sect1>How do I compile to native code?
<p>You might be able to use <prgn>gcj</prgn> to compile the program.
And use <prgn>gcj</prgn> to convert bytecode to native code. The entire
software chain is free.
<chapt id="browser-java">Java Plugins for Browsers
<p>
<list>
<item>You can install the package icedtea-6-plugin or icedtea-7-plugin in <em>wheezy</em></item>
</list>
<chapt>Java Servlets
<p>
<sect>How can I make Java servlets work?
<p>You can use:
<list>
<item>Apache <package>tomcat6</package> from <url id="http://tomcat.apache.org">.
<item>Eclipse <package>jetty</package> from <url id="http://www.eclipse.org/jetty/">.
</list>
<chapt>Java Policy
<p>
<sect>Is there a Java policy for Debian?
<p>
It is still in the works. The current policy addresses <em>some</em>
of the problems. It has not been officially released. You can find
it at <url id="http://www.debian.org/doc/packaging-manuals/java-policy/">.
The Java Policy can also be found in the <package>java-common</package>
package.
<sect>Are there holes in the Java Policy?
<p>Yes, some until under discussion. Please check out the
<url id="http://bugs.debian.org/java-common" name="bugs against
the java-common package">. Thus it is <em>very</em> inconvenient to
use several compilers of virtual machines since there is not one
CLASSPATH setting for all of them.
<chapt>Other Java alternatives for Debian
<p>If the Java packages provided in Debian are not sufficient for your
needs you might need to take a look at other alternatives. Please understand
that these alternatives are not supported by the Debian project directly,
you might get help, however, from the debian-java mailing list if you
encounter issues with them.
<P>Some of the alternatives presented use Debian packages which is
convenient, since the user/administrator does not need to care on installation
issues. However, mixing packages that come from a source which is not
the Debian project might cause conflicts with your installation some times.
Of course, Debian tries to integrate as many free software efforts as
possible, so some of the alternatives described below might (if license
permits) be included in Debian in the near future.
<sect>Java programs not yet available on Debian
<p>
The following are programs that have not yet been packaged for Debian
nor is there an installer. There are quite a lot Java programs out
there.
<p>A list of missing packages is maintained on the
<url id="http://wiki.debian.org/Java/RequestedPackages" name="Debian Wiki - Java Packaging Wishlist">.
