Subject TomeePlus Dropin not working with Tomcat 7.0.54
Date Wed, 09 Jul 2014 14:11:51 GMT
Hello Guys,

I'm new to this forum and also new to TomEE - Hello Everybody.

I' m writing a small application using REST/EJB/JPA. Everything works fine with TomEE+
BIG BUT: My customer wants to reuse an existing Tomcat 7.0.54 installation. So, for testing
purpose I loaded Tomcat 7.0.54 from TomEE download page and droped the TomEE .war distribution
"tomee-plus-webapp-" into it after renaming it to "tomee.war" which lead to the
following stacktrace (see below). Any suggestions for this? Thanks in advance for your feedback.
