The manual installation process is significantly harder then the automatic installation which we normally recommend. In this installation process you will do the following:
Once Tomcat has been installed , the OpenEJB plugin for Tomcat can be installed. The war can be obtained from the download page
The commands in this example are executed from within the Tomcat installation directory.
Be careful, this is the most error prone step. A web application does not contain a root directory, so if you unpack it in the wrong directory, it is difficult to undo. Please, follow this step closely, and most importantly make sure you execute the unpack command from within the new webapps/openejb directory
Due to the structure of war files, you must create a new directory for OpenEJB, change to the new directory and execute the unpack command from within the new directory. If you get this wrong, it is difficult to undo, so follow the steps closely.

All Tomcat listener classes must be available in the Tomcat common class loader, so the openejb-loader jar must be copied into the Tomcat lib directory.
C:\apache-tomcat-6.0.14>copy webapps\openejb\lib\openejb-loader-3.0.0-SNAPSHOT.jar lib\openejb-loader.jar
1 file(s) copied.
apache-tomcat-6.0.14$ cp webapps/openejb/lib/openejb-loader-*.jar lib/openejb-loader.jar
Add the following <Listener
className="org.apache.openejb.loader.OpenEJBListener" />
to your conf/server.xml file to load the OpenEJB listener:
The snippet is shown below
<!-- Note: A "Server" is not itself a "Container", so you may not
define subcomponents such as "Valves" at this
level.
Documentation at /docs/config/server.html
-->
<Server port="8005" shutdown="SHUTDOWN">
<!-- OpenEJB plugin for tomcat -->
<Listener
className="org.apache.openejb.loader.OpenEJBListener" />
<!--APR library loader. Documentation at /docs/apr.html -->
<Listener
className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
Tomcat contains an old non-compliant version of the javax.annotation classes and these invalid classes must be updated so OpenEJB can process annotations. Simply, replace the annotations-api.jar in the Tomcat lib directory with the updated annotations-api.jar in the OpenEJB war.
C:\apache-tomcat-6.0.14>copy webapps\openejb\tomcat\annotations-api.jar
lib\annotations-api.jar
Overwrite lib\annotations-api.jar? (Yes/No/All): y
1 file(s) copied.
apache-tomcat-6.0.14$ cp webapps/openejb/tomcat/annotations-api.jar

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.
First, copy the OpenEJB JavaAgent jar into the lib directory.
C:\apache-tomcat-6.0.14>copy webapps\openejb\lib\openejb-javaagent-3.0.0-SNAPSHOT.jar lib\openejb-javaagent.jar
1 file(s) copied.
apache-tomcat-6.0.14$ cp webapps/openejb/lib/openejb-javaagent-*.jar lib/openejb-javaagent.jar
Simply, add the snippet marked below in bin/catalina.bat (Windows) or bin/catalina.sh (Unix) file to enable the OpenEJB javaagent:
if not exist "%CATALINA_BASE%\conf\logging.properties" goto noJuli
set JAVA_OPTS=%JAVA_OPTS%
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file="%CATALINA_BASE%\conf\logging.properties"
:noJuli
# Start of Snippet to add
rem Add OpenEJB javaagent if not exist
"%CATALINA_BASE%\webapps\openejb\lib\openejb-javaagent.jar" goto
noOpenEJBJavaagent set
JAVA_OPTS="-javaagent:%CATALINA_BASE%\webapps\openejb\lib\openejb-javaagent.jar"
%JAVA_OPTS% :noOpenEJBJavaagent
# End of Snippet to add
rem ----- Execute The Requested Command

echo Using CATALINA_BASE: %CATALINA_BASE%
echo Using CATALINA_HOME: %CATALINA_HOME%
# Set juli LogManager if it is present
if [OPENEJB: -r "$CATALINA_BASE"/conf/logging.properties ](openejb:--r-"$catalina_base"/conf/logging.properties-.html)
; then
JAVA_OPTS="$JAVA_OPTS
"-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"
"-Djava.util.logging.config.file="$CATALINA_BASE/conf/logging.properties"
