Subject Re: Scripting support
Date Thu, 09 Feb 2012 13:06:07 GMT
Romain,
This is not running interactively.
https://issues.apache.org/jira/browse/OPENEJB-1734

By interactive, I mean to have a shell similar to groovy shell running
locally on my desktop, with all the bindings in the openejb context
available.
So for example, I can say

CalculatorRemote.sum(1,1)
and it will show the results
===> 2


If I have time next week, I will for openejb on github and will add this.
