Affects Version/s: 1.5
Fix Version/s: None
Environment:Tomcat 5.5.26, Axis2 war 1.4.1/1.5, Rampart 1.4
We have an Axis2 1.4.1 runtime, which has Rampart module deployed, but not globally engaged (using the default axis2.xml from axis2.war)
We have two services, both of them are secured (Rampart is engaged for each service by using <module ref="rampart"/> in services.xml).
When Rampart is disengaged on one of the services, it happens that the Rampart handler is removed from the security phase. This practically disables access to the other secured service, since secured service requests are not handled by Rampart anymore (no handler in security phase) and when attempting to invoke it, Axis2 throws a mustUnderstand check failed for the security header:
[ERROR] Must Understand check failed for header http://docs.oasis-open.org/wss/
004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd : Security
We examined the module disengage logic, and it seems that the handler removal takes place in AxisOperation#onDisengage(AxisModule module). The code there would remove module's handlers from global chains if the module is not engaged on service nor on gloabal level. What is the reason for this, and what if the module is engaged on another service (as in our case)?
I attach two simple services you can simulate this with. They are based on Rampart's Tomcat policy sample, but are secured
with a simple Username supporting token.
Steps to simulate the problem:
1. Deploy both services to Axis2 1.4.1/1.5 webapp having Rampart deployed (but not engaged in axis2.xml)
2. Using the web administration intefrace, disengage Rampart module on one of the services
3. Try to invoke the other service using the Client.java class (or by any other means)
