h1. Install and run Tomcat 6 (last tested with 6.0.14)

Tomcat 5.x is not supported due to classloading differences and annotation processing support. For Tomcat installation documentation see [http://tomcat.apache.org/tomcat-6.0-doc/setup.html]. 

Note on Unix platforms (Linux, MacOSX):
If you unpacked the Tomcat tar.gz file, the scripts are already executable.  If not, the following command will make all shell scripts executable: {code}$ chmod u+x bin/*.sh{code}

Note on all platforms: the following instructions assume running Tomcat using the bin/catalina.sh or bin/catalina.bat scripts and not running as a service or daemon.

h1. {anchor:install-openejb}Install OpenEJB

The OpenEJB plugin distributable for Tomcat runs as a separate web application and is provided as zip file.
Current version: openejb-tomcat-3.0.0-SNAPSHOT-bin.zip

h2. Unpack the OpenEJB Tomcat plugin in the Tomcat webapps directory to deploy the OpenEJB plugin container.

The OpenEJB directory should contain the following files:

Note

title	READ THIS FIRST

Restrictions
o The installer only runs on Unix. Windows support will require a tweaked catalina.bat and a work around for Windows file locking.
Cygwin won't work either and will require even more work arounds in the Unix code to deal with pathing problems.
o There is no uninstaller. Currently, the installer deletes the non-compliant Tomcat annotations-api.jar so in addition to backing out
the changes, you need to restore this file.
o Annotations in servlets to OpenEJB resources (EJBs,PersistenceUnits, Topics, Queues, DataSources, etc) don't resolve.
You will have to use global JNDI for the time being.
o There is no security integration. Please do not try using secured EJB in Tomcat embedded mode yet.
o We only support Tomcat 6 and we suggest you use the newest version as we haven't tested any older 6 revisions. We could potentially
support older versions of Tomcat if there were enough demand, but it is doubtful there will be since OpenEJB 3 requires Java5.

Install Tomcat 6

If you already have Tomcat 6 installed, skip to Install OpenEJB.

Unpack Tomcat

Unpack the Tomcat zip file which will create a new directory containing the complete Tomcat installation.

...

$ jar -xvf apache-tomcat-6.0.14.zip 
  created: apache-tomcat-6.0.14/
  created: apache-tomcat-6.0.14/bin/
  created: apache-tomcat-6.0.14/conf/
...snip...

Change to the new Tomcat installation directory.

...

$ cd apache-tomcat-6.0.14/

The Tomcat installation should contain the following files:

...

apache-tomcat-6.0.14$ ls
LICENSE        RELEASE-NOTES  bin/           lib/           temp/          work/
NOTICE         RUNNING.txt    conf/          logs/          webapps/

Make shell scripts executable

The shell scripts in the Tomcat installation are not executable by default, so in order to execute them, you must set mark them as executable. If you unpacked the Tomcat tar.gz file, the scripts are already executable. The following command will make all shell scripts executable:

Code Block
apache-tomcat-6.0.14$ chmod u+x bin/*.sh

Start Tomcat

Execute the following command to start the Tomcat server to verify it is functioning properly:

...

apache-tomcat-6.0.14$ bin/startup.sh 
Using CATALINA_BASE:   /your/tomcat/installation/apache-tomcat-6.0.14
Using CATALINA_HOME:   /your/tomcat/installation/apache-tomcat-6.0.14
Using CATALINA_TMPDIR: /your/tomcat/installation/apache-tomcat-6.0.14/temp
Using JRE_HOME:        /your/java/installation

NOTE: Your output will be different from the example above due to differences in installation location.

Verify Tomcat is Running

Visit http://localhost:8080/ and you should see the Tomcat welcome page.

Stop Tomcat

Shutdown Tomcat by executing the following command:

...

apache-tomcat-6.0.14$ bin/shutdown.sh
Using CATALINA_BASE:   /your/tomcat/installation/apache-tomcat-6.0.14
Using CATALINA_HOME:   /your/tomcat/installation/apache-tomcat-6.0.14
Using CATALINA_TMPDIR: /your/tomcat/installation/apache-tomcat-6.0.14/temp
Using JRE_HOME:        /your/java/installation

NOTE: Your output will be different from the example above due to differences in installation location.

...

Once Tomcat has been installed, the OpenEJB plugin for Tomcat can be installed. The commands in this example are executed within the Tomcat installation directory.

Unpack OpenEJB Tomcat plugin in Tomcat webapps directory

1. Change to the webapps directory:

...

apache-tomcat-6.0.14$ cd webapps

2. Unpack the openejb-tomcat-3.0.0-SNAPSHOT-bin.zip file.

...

apache-tomcat-6.0.14/webapps$ jar -xvf ../openejb-tomcat-3.0.0-SNAPSHOT-bin.zip
  created: openejb/
  created: openejb/WEB-INF/
  created: openejb/lib/
 inflated: openejb/lib/geronimo-javamail_1.4_spec-1.1.jar
 inflated: openejb/lib/xbean-finder-3.1.jar
...snip...

3. The OpenEJB directory should contain the following files:

...

apache-tomcat-6.0.14/webapps$ ls openejb
WEB-INF/     lib/         openejb.xml

4. Start tomcat again

5. Visit http://localhost:8080/openejb/installer^{Image Removed} and click on the install button

6. Assuming you don't get any errors, reboot tomcat

At this point OpenEJB will be installed

Return to the Tomcat install directory



{code:none}apache-tomcat-6.0.14/webapps$

cd ..{code} h2. Add the OpenEJB listener to Tomcat Tomcat listeners must be available in the Tomcat common class loader, so the openejb-loader jar must be copied into the Tomcat lib directory. {code:none} apache-tomcat-6.0.14$ cp webapps/openejb/lib/openejb-loader-3.0.0-SNAPSHOT.jar lib/{code}

ls openejb
WEB-INF/     lib/         openejb.xml
{code}

h2. Unix users use http://localhost:8080/openejb/installer and click on the install button

h2. Windows users need to do the following:

h3.1 Install the OpenEJB listener to Tomcat.

Add the following {highlight}highlighted lines{highlight} to your conf/server.xml file to load the OpenEJB listener:
 
{panel:title=conf/server.xml}
<!-- Note:  A "Server" is not itself a "Container", so you may not
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;define subcomponents such as "Valves" at this level.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Documentation at /docs/config/server.html
 -->
<Server port="8005" shutdown="SHUTDOWN">
&nbsp;&nbsp;{highlight}<!-- OpenEJB plugin for tomcat -->{highlight}
&nbsp;&nbsp;{highlight}<Listener className="org.apache.openejb.loader.OpenEJBListener" />{highlight}

&nbsp;&nbsp;<!--APR library loader. Documentation at /docs/apr.html -->
&nbsp;&nbsp;<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
...snip...
{panel}

h2

h3.1 Delete the Tomcat annotations-api.jar file

Tomcat contains an old non-compliant version of the javax.annotation classes and these invalid classes must be removed so OpenEJB can process annotations.  Simply, rename the annotation-api.jar so it doesn't end with {{".jar"}}.  For example:

{code:none}

apache-tomcat-6.0.14$

$ mv lib/annotations-api.jar lib/annotations-api.jar-INVALID{code}

h2

h3.1 Add OpenEJB javaagent to Tomcat startup

OpenJPA, the Java Persistence implementation used by OpenEJB, currently must enhanced persistence classes to function properly, and this requires the installation of a javaagent into the Tomcat startup process.

Simply, add the following {highlight}highlighted lines{highlight} to the bin/catalina.

sh

bat file to enable the OpenEJB javaagent:

{panel:title=bin/catalina.sh}
...snip...
\# Set juli LogManager if it is present
if [ -r "$CATALINA_BASE"/conf/logging.properties ]; then
&nbsp;&nbsp;JAVA_OPTS="$JAVA_OPTS "-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager" "-Djava.util.logging.config.file="$CATALINA_BASE/conf/logging.properties"
fi

{highlight}\# Add OpenEJB javaagent
if [ -r "$CATALINA_BASE"/webapps/openejb/lib/openejb-javaagent-3.0.0-SNAPSHOT.jar ]; then
&nbsp;&nbsp;JAVA_OPTS=""-javaagent:$CATALINA_BASE/webapps/openejb/lib/openejb-javaagent-3.0.0-SNAPSHOT.jar" $JAVA_OPTS"
fi{highlight}

\# ----- Execute The Requested Command -----------------------------------------

\# Bugzilla 37848: only output this if we have a TTY
if [ $have_tty -eq 1 ]; then
&nbsp;&nbsp;echo "Using CATALINA_BASE:   $CATALINA_BASE"
...snip...
{panel} 

*NOTE:* The example above is an excerpt from the middle of the bin/catalina.sh file.  Search for "Execute" in the file to locate the correct position in the file to add the new lines.
