If you prefer, TomEE can be setup by deploying a .war file into an existing Tomcat 7.x installation, as opposed to using the all-in-one bundle. This guide provides a set of step-by-step instructions to this approach. Please note that TomEE 1.7.x does not recommend Tomcat versions less than 7.0.54. Tomcat 8 is not currently supported in the released version, but you can check out the developer branch to see progress here.

  • Download the Apache Tomcat 7.0.55 server. http://tomcat.apache.org/download-70.cgi

  • Unzip the Tomcat distribution file.

  • Update $CATALINA_HOME/conf/tomcat-users.xml to add a tomee user to allow access to the installer page.

     <!-- Activate/create these lines to get access to TomEE GUI -->
     <role rolename="tomee-admin" />
     <user username="tomee" password="tomee" roles="tomee-admin" />
  • Download the .war file you wish to use - either the tomee-webapp-1.7.1.war (for the webprofile installation) or tomee-webapp-plus-1.7.1.war (for the plus version).

  • Copy and rename the .war file to $CATALINA_HOME/webapps/tomee.war (the .war filename is important).

  • Start Tomcat.

  • Go to the TomEE installer webapp (http://localhost:8080/tomee/) and login with the user you added to tomcat-users.xml.

  • Verify the values and click "Confirm".
