New Revision: 576045
URL: http://svn.apache.org/viewvc?rev=576045&view=rev
Log:
- Fixed the IvmContext to properly throw NameAlreadyBoundException
rather than allowing the bind to cover a previous binding.
- Severely fixed up the information, recovery, and flexibility
associated with jndi binding and collisions.
- Added a new system property openejb.jndiname.failoncollision which
defaults to true, when set to false attempting to bind an object to
jndi with a name that already exists results in logging an error but
the app still deploys
