Subject RE: How do you control the initialization order of services
Date Wed, 08 Apr 2015 13:58:25 GMT
The order is not alphabetical (at least not in axis2/c 1.6.0).  Here is what I am seeing in
the apache error.log file.  My goal is to have the Common services initialized first.  Currently,
it is the 6th service being initialized.  For right now, I am ok since the other 3 services
that are dependent on Common (MarketPlace, RPSAdmin, and MRO) are being initialized after
Common.  However, it looks like its working by chance, not design.

If the order were alphabetical, then I would expect the order to be:


1.       Common

2.       ExternalInterface

3.       ExternalUpdate

4.       FreeWheel

5.       MarketPlace

6.       Network

7.       Placement

8.       Requirement

9.       Rollover

10.   RotationMapping


For another configuration I see:

Hi Bob,

The files will be sorted in alphabetical order when reading the services from the service
deployment directory and the services are initialized in that order as well.

I have a server that is made up of multiple services.  Some services are mandatory, other
services are optional based on what has been licensed to the end user.  Is there a way to
assure that the mandatory services are initialized (via axis2_svc_skel_<name>_create())
 before the optional ones?
