What’s TomEE?

@JacekLaskowski

Apache TomEE, pronounced "Tommy", is an all-Apache Java EE 6 Web Profile certified stack where

Tomcat is top dog. Apache TomEE is assembled from a vanilla Apache Tomcat zip file. We start with Tomcat, add our jars and zip up the rest. The result is Tomcat

with added EE features - TomEE.

Files modified - conf/server.xml

@JacekLaskowski

Files modified - conf/tomcat-users.xml

@JacekLaskowski

Files modified - conf/tomcat-users.xml

@JacekLaskowski

As a matter of fact, the change is only needed for webapps/tomee and hence optional

Files modified - conf/tomcat-users.xml

@JacekLaskowski

As a matter of fact, the change is only needed if using OpenJPA or EclipseLink with no build-time enhancements

and hence optional

Files modified - bin/setclasspath.sh

Files modified - bin/setclasspath.sh

@JacekLaskowski

As a matter of fact, the directory doesn’t exist whatsoever and is optional, too
