I have three general JavaEE + Tomcat questions:

  1. According to this link (Using Hibernate with Tomcat) running Hibernate in Tomcat is possible (despite Tomcat not supporting JPA).
    Does anyone know if I’ll run into problems with this configuration (Hibernate on Tomcat)?

  2. Can I do something similar to get EJB3.1 support in Tomcat?
    For example, by dropping the correct files into WEB-INF/lib and WEB-INF/classes could I run EJB3.1 in a standard Tomcat7 container (not TomEE)?
    If yes, which EJB3.1 providers are recommended?

  3. Generally, is it possible to run any JavaEE technology from within Tomcat as long as the appropriate libraries and configuration files are placed in WEB-INF/lib and WEB-INF/classes?
    Or, is it only possible to run the technologies for which Tomcat supports the interfaces?

Thanks in advance for all help!

    1. No problems – it’s very common.
    2. Yes. For example OpenEJB is the predecessor to TomEE. Per the downloads page (below).
    3. No.

    Drop-in WARs.

    A version of Apache OpenEJB that can be dropped into any
    Tomcat 7.x install effectively creating your own Apache TomEE Web
    Profile or Apache TomEE Plus.
