Warning: many pages on this wiki imply that a servlet container must be installed before running Cocoon, this is wrong - see NoServletContainerRequired. A basic installation of Cocoon for test or development purposes can be very simple.
Update The whole procedure has been tested with Cocoon-2.1.5.1 on a Suse Linux 9.1 with j2sdk1.4.2_05 and jakarta-tomcat-5.0.27 and there are no changes so far. For using this instruction you just need to replace cocoon-2.1.4 with cocoon-2.1.5.1.
This description has been created on a SuSE Linux 9.0 system with Tomcat 5.0.19 and j2sdk1.4.2_04 installed. As a good starting point for doing virtual hosting with Cocoon, Cocoon will be the default host and will listen to http://cocoon:8080/ instead of http://localhost:8080/cocoon/. Tomcat is already installed in /opt and Cocoon, as shown below, will be installed there as well instead of being deployed to Tomcat's "webapps" directory.

Get Cocoon
Go to the directory you are using for downloads and create a subdirectory cocoon. Step into this cocoon directory and WGET Cocoon an its MD5 hash from the download server.
{{{otto@linux:~> cd /tmp/
otto@linux:/tmp> mkdir cocoon otto@linux:/tmp> cd cocoon/
otto@linux:/tmp/cocoon>
otto@linux:/tmp/cocoon> wget -nd http://www.apache.org/dist/cocoon/cocoon-2.1.4-src.tar.gz.md5

=> `cocoon-2.1.4-src.tar.gz'
}}}
After download is complete you should check MD5 sum of your download. Either do md5sum -c *.md5 or check it manually.
otto@linux:/tmp/cocoon> md5sum cocoon-2.1.4-src.tar.gz 65a099094217ef0621e832ad5aa1cfc9 cocoon-2.1.4-src.tar.gz otto@linux:/tmp/cocoon> cat cocoon-2.1.4-src.tar.gz.md5 65A099094217EF0621E832AD5AA1CFC9 cocoon-2.1.4-src.tar.gz otto@linux:/tmp/cocoon>
Unpacking cocoon-2.1.4-src.tar.gz will create a new directory cocoon-2.1.4.

Build Cocoon
Step into cocoon-2.1.4 and list its content. You might read the INSTALL.txt and README.txt files, and check what's about the blocks.properties and build.properties.

Normally it shouldn't be necessary to do any changes to the above files. You can directly start the program building cocoon.
otto@linux:/tmp/cocoon/cocoon-2.1.4> ./build.sh webapp
Building Cocoon will take some time and generate some output on your screen. Finally it will end up with
BUILD SUCCESSFUL Total time: 4 minutes 37 seconds otto@linux:/tmp/cocoon/cocoon-2.1.4>
The building procedure should have created a new directory build within cocoon-2.1.4. You may check it.
otto@linux:/tmp/cocoon/cocoon-2.1.4> cd build/ otto@linux:/tmp/cocoon/cocoon-2.1.4/build> ls -al insgesamt 1 drwxr-xr-x 4 otto users 104 2004-05-05 16:10 . drwxr-xr-x 7 otto users 672 2004-05-05 16:02 .. drwxr-xr-x 11 otto users 392 2004-05-05 16:12 cocoon-2.1.4 drwxr-xr-x 8 otto users 336 2004-05-05 16:13 webapp
What we are going to use is the subdirectory webapp.
Install Cocoon
All steps until here should have been done without root privileges. Now become root su root and create a cocoon directory within /opt.
otto@linux:/tmp/cocoon/cocoon-2.1.4/build> su root Password: (Enter your password) linux:/tmp/cocoon/cocoon-2.1.4/build # mkdir /opt/cocoon
Now move your /tmp/cocoon/cocoon-2.1.4/build/webapp/ directory into /opt/cocoon/.
linux:/tmp/cocoon/cocoon-2.1.4/build # mv webapp/ /opt/cocoon/ linux:/tmp/cocoon/cocoon-2.1.4/build # ls -al /opt/cocoon/ insgesamt 0 drwxr-xr-x 3 root root 72 2004-05-05 16:35 . drwxr-xr-x 14 root root 400 2004-05-05 16:25 .. drwxr-xr-x 9 otto users 360 2004-05-05 16:27 webapp linux:/tmp/cocoon/cocoon-2.1.4/build #
Now, we want Cocoon to act as the Default Context of its own host that we are going to configure in Tomcat. This sounds complicated? So let's do it. In Tomcat's configuration we'll make /opt/cocoon the Appliation Base for a new host. Any host setup in Tomcat will check it's configured Appliation Base for a subdirectory ROOT and regard this one as it's default context. So, let's simply rename our webapp to ROOT, spelt with four upper case letters.
linux:/tmp/cocoon/cocoon-2.1.4/build # cd /opt/cocoon/ linux:/opt/cocoon # ls -al insgesamt 0 drwxr-xr-x 3 root root 72 2004-05-05 16:35 . drwxr-xr-x 14 root root 400 2004-05-05 16:25 .. drwxr-xr-x 9 otto users 360 2004-05-05 16:27 webapp linux:/opt/cocoon # mv webapp/ ROOT/ linux:/opt/cocoon # ls -al insgesamt 0 drwxr-xr-x 3 root root 72 2004-05-05 16:37 . drwxr-xr-x 14 root root 400 2004-05-05 16:25 .. drwxr-xr-x 9 otto users 360 2004-05-05 16:27 ROOT linux:/opt/cocoon #
This will make ROOT to be recognized by Tomcat as the default webapp in /opt/cocoon/. Now let's make Tomcat regard /opt/cocoon/ as a webapp directory:
Edit server.xml
If you happened to have Tomcat already running, you should stop it now! Go to Tomcat's configuration directory
linux:/opt/cocoon # cd ../jakarta-tomcat-5/conf/ linux:/opt/jakarta-tomcat-5/conf # ls -al insgesamt 101 drwxr-xr-x 3 root root 496 2004-05-05 16:26 . drwxr-xr-x 11 root root 352 2004-02-25 08:57 .. drwxr-xr-x 4 root root 96 2004-02-25 09:09 Catalina -rw------- 1 root root 6804 2004-02-14 11:26 catalina.policy -rw------- 1 root root 2715 2004-02-14 11:26 catalina.properties -rw------- 1 root root 778 2004-02-14 11:26 jk2.properties -rw------- 1 root root 1128 2004-02-14 11:26 server-minimal.xml -rw-r--r-- 1 root root 1756 2004-03-05 12:45 server.xml -rw-r--r-- 1 root root 433 2004-05-05 16:26 tomcat-users.xml -rw------- 1 root root 37477 2004-02-14 11:26 web.xml
and with your favourite editor open the file server.xml. Don't forget to backup a copy before. Search for the starting tag of Catalina Engine
<Engine defaultHost="localhost" name="Catalina">
Below it, add the following lines that create a new host cocoon with an Application Base ../cocoon. The relative path used here starts from $Catalinahome, which in our case is /opt/jakarta-tomcat-5/.
<Host appBase="../cocoon" name="cocoon">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="cocoon_log." suffix=".txt" timestamp="true"/>
</Host>
and change Catalina's default host to cocoon
<Engine defaultHost="cocoon" name="Catalina">
So that, excluded all the comments, Catalina now looks like
<Engine defaultHost="cocoon" name="Catalina">
<Host appBase="../cocoon" name="cocoon">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="cocoon_log." suffix=".txt" timestamp="true"/>
</Host>
<Host appBase="webapps" name="localhost">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_log." suffix=".txt" timestamp="true"/>
</Host>
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="catalina_log." suffix=".txt" timestamp="true"/>
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"/>
</Engine>
Save your changes, close "server.xml" and restart Tomcat
linux:/opt/jakarta-tomcat-5/conf # cd .. linux:/opt/jakarta-tomcat-5 # bin/startup.sh Using CATALINA_BASE: /opt/jakarta-tomcat-5 Using CATALINA_HOME: /opt/jakarta-tomcat-5 Using CATALINA_TMPDIR: /opt/jakarta-tomcat-5/temp Using JAVA_HOME: /usr/lib/java linux:/opt/jakarta-tomcat-5 #
Now it's done. Become normal user and start your browser. If you follow the link http://cocoon:8080/ it should now take you to Cocoon's welcome page whereas http://localhost:8080/ still will go to Tomcat's welcome page with its docs and examples. But, as we changed Catalina's default host to Cocoon, now any other http://anyhost:8080/ will go to Cocoon as well. We will use this feature for doing virtual hosting with Cocoon in a future description.
