I think I have tomcat integrated with Maven4MyEclipse in MyEclipse 6.5. I seem to be having an issue with the Web Project’s context name and the Maven context name when used to do a tomcat:redeploy.
I *think* the issue is keeping the Web Project’s context name in sync with the Maven generated context name? How is this handled?
My Project Settings has the Web Context-root: /cot
My pom.xml looks like:
<modelVersion>4.0.0</modelVersion> <groupId>cot</groupId> <artifactId>cot</artifactId> <packaging>war</packaging> <name/> <version>0.0.1-SNAPSHOT</version> <description/>This is the error I am seeing:

Please note, Tomcat server installation embedded into MyEclipse was specifically tweaked for optimal performance when using MyEclipse deployment tools and may not be completely compatible with external tools. You should use your own Tomcat installation with Maven.
