We have a bug in the 1.3 release when ESME runs in Tomcat. Links to users in the main message display have the wrong URL (for example, http://localhost:8080/esme/esme/user/test2 instead of http://localhost:8080/esme/user/test2).
I've created a JIRA item for the bug: https://issues.apache.org/jira/browse/ESME-363 D.
