I'm currently on Tomcat 7.0.21, JDK1.6.29, and WTP 3.3.1 (running on Eclipse Indigo.) I'm not sure which version of M2E I'm running. My Project builds and deploys fine when I either do a mvn install and run Tomcat outside of Eclipse, or deploy to the server via WTP with the "Serve Modules without publishing" unchecked.
However, when I start the server via WTP with the no-publish box checked, Tomcat won't start successfully, failing with:
Dec 29, 2011 4:09:39 PM org.apache.catalina.startup.ContextConfig processAnnotationsJndi
SEVERE: Unable to process JNDI URL [jndi:/localhost/plutom-ws/WEB-INF/classes] for annotations
java.io.FileNotFoundException: jndi:/localhost/plutom-ws/WEB-INF/classes

If I manually create the classes directory, it then complains about classes/com It seems like there's a conflict between a classloader and a file path resolve somewhere?
This is unfortunately a known bug between Eclipse WTP and Tomcat 7. Here are the relevant Bugzilla entries:
Tomcat 7 + Serve Modules without publishing fails to find classpath resources
Apparently the fix is known, it just hasn't been applied yet. I guess it isn't a common use-case, because otherwise more people would be requesting it to be fixed. Its too bad, its a very useful feature.
