[ http://issues.apache.org/jira/browse/AXIS2-1120?page=comments#action_12433341 ] Deepal Jayasinghe commented on AXIS2-1120: ------------------------------------------
Well , your first option was there in Axis2 in the initial stage , and when service specific module try to put handlers into global phase Axis2 was throwing exception. But we had to change that when it come to real module like security and RM , they wanted not to throw that exception. And final conclusion was to implement the module or write the handler keeping where it is belong in mind. For example if you engage a module called "foo" to service called "bar" and it put handler into global phases , then as a handle write you have to check whether you are engaged to message coming in and do the processing, using message context you can check whether you are engage or not. I also more reluctant to change the Axis2 initial design , I mean allowing service specific module to put handler into global phases , but finally I have to agree to the community design. Any way at this moment I dont think we can go ahead and change that , only option we have is to write proper document explaining how it works and how should you write handler. > Phases concept is too confusing - please change for v1.1 > -------------------------------------------------------- > > Key: AXIS2-1120 > URL: http://issues.apache.org/jira/browse/AXIS2-1120 > Project: Apache Axis 2.0 (Axis2) > Issue Type: Improvement > Components: core > Affects Versions: 1.0 > Reporter: Thilo Frotscher > Priority: Blocker > > With Axis2 1.0 it can easily happen that you engage a module with services > without realizing it! > This is because even if explicitly engaging a module with a *single* service > or a *single* operation, its handlers will automatically be invoked for *all* > services if they belong to a global phase.
