[jacorb-developer] PortableInterceptor and ServantLocator Together Cause Exception

Hi Nick,
I turned on jacorb info-level logging and I see output about a transient POA being used which is strange ?
I.e.
<snip>
tid=RequestProcessor-5,receive_request_service_contexts getDay
tid=RequestProcessor-5,ServantLocator.preinvoke, operation=getDay; strOid=IDL:demo/hello/DayFactory:1.0
INFO | AOM.java :176 | 2012-06-27 18:28:51,051 | AOM | add | tid:RequestProcessor-5 | oid: 00 02 3D 4A 2E 11 4
B 49 0F 30 10 06 30 46 38 14 14 1B 48 4C ..=J..KI.0..0F8...HL1B .object is activated
INFO | POA.java :1271 | 2012-06-27 18:28:51,051 | POA | getImplName | tid:RequestProcessor-5 | Using server ID (4175497
725) for transient POA
** returning servant **
<snip>
Can you verify that you see the same output ?
Btw- I changed POA.java to print the poa name and this is what I get when I rerun it:
tid=RequestProcessor-5,ServantLocator.preinvoke, operation=getDay; strOid=IDL:demo/hello/DayFactory:1.0
INFO | AOM.java :176 | 2012-06-27 20:31:37,596 | AOM | add | tid:RequestProcessor-5 | oid: 00 02 3F 30 3F 2D 4
C 15 0A 25 10 06 30 46 38 14 14 1B 48 4C ..?0?-L..%..0F8...HL1B .object is activated
INFO | POA.java :1271 | 2012-06-27 20:31:37,596 | POA | getImplName | tid:RequestProcessor-5 | Using server ID (8752004
331) for transient POA=RootPOA
Note "RootPOA" ?
Clearly the DayFactory servant is hosted by the simple_persistent poa so not sure what's up ?
thanks again,
mike

Hi Mike,
Something like:
servant._this_object (orb);
Your test works fine for me then. By the way - thanks for providing it
in such a nice form complete with command line - makes it so much easier
to take a look and run it ;-)
Cheers
Nick
