Samisa Abeysinghe updated AXISCPP-421:
--------------------------------------
Component: Handlers
> Problems with handlers
> ----------------------
>
> Key: AXISCPP-421
> URL: http://issues.apache.org/jira/browse/AXISCPP-421
> Project: Axis-C++
> Type: Bug
> Components: Handlers
> Environment: n/a
> Reporter: Fred Preston
> Priority: Minor
>
> I am investigating handlers, and there seems to be a problem with the number
> of times init and fini are called (I would expect, when everything is working
> correctly for the init and fini methods to be called once only). Also when
> the WSDD file contains global and transport type handlers some fini methods
> on some handlers are not called at all. Here is a simple WSDD with just one
> Client handler:-
> <?xml version="1.0" encoding="UTF-8"?>
> <deployment xmlns="http://xml.apache.org/axis/wsdd/";
> xmlns:C="http://xml.apache.org/axis/wsdd/providers/c";>
> <service name="ServiceHandler" provider="CPP:DOCUMENT" description="Service
> Handlers">
> <requestFlow>
> <handler name="myClientHandleReq" type="C:\myClientHandler.dll">
> </handler>
> </requestFlow>
> <responseFlow>
> <handler name="myHandle1Res" type="C:\myHandler1.dll">
> </handler>
> </responseFlow>
> </service>
> </deployment>
> And this is the debug I get: (Notice how there are two calls to init)
> 0> myClientHandler::myClientHandler() <-- Method entry
> 0< myClientHandler::myClientHandler() <-- Method exit
> 0> myClientHandler::init() <-- Method entry
> 0< myClientHandler::init() <-- Method exit
