I have a web app deployed as a ear file that contains a war file. The ear file is named "MyApp.ear" and the war file it contains is named "MyApp-war.war". I have the code below in application.xml. <?xml version="1.0"?> <application version="7" xmlns="http://xmlns.jcp.org/xml/ns/javaee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/application_7.xsd";> <display-name>MyApp</display-name> <module> <web> <web-uri>MyApp-war.war</web-uri> <context-root>/MyApp</context-root> </web> </module> </application> With the above config, the app will deploy the first time, but if I restart TomEE the app will fail with the errors below. So, if it's a fresh first-time deployment, it works, otherwise it doesn't work.

In this case, the Tomcat Web Application Manger lists two applications, "/MyApp-ear" and "/MyApp". It seems TomEE gets confused when the ear file is named MyApp.ear with the implied context-root for the ear being "MyApp" and the context-root for the war file is also specified to be "MyApp" in application.xml. Can I name the ear file "MyApp.ear" and also have the context-root for the war file be "MyApp"? Is there a way to change the context-root for the ear file besides changing the ear filename? Thanks, Terry
