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+ 1.6.0.2 Standalone.
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-1.6.0.2.war" 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.

Frank
