Subject Re: [Axis2] Giving modules the ability to define their own phases
Date Mon, 03 Apr 2006 09:52:29 GMT


My suggestion is Axis2 admin sets a flag in axis2.xml, allowing module
authors to add their own phases, during module init.

If the flag is set, then Sandesha can add a phase.

BTW, why do you wanna have your own phase ?
