Handlers in Axis2
Hello,
When using the same handler for inflow and outflow messages, does axis2
create a seperate object of the handler for the different flow. It uses
the same object for all inflows, but is there a second object for all
outflow messages? It is confusing as the two instances of the handler
(if there are two instances) have the same object hashCode, yet when
using a java collection object within the handler, the outflow cannot
see the same collection object as the inflow?? Any suggestions?

I think I seen this a while back, and since then, what I do is simple but
effective: stop server, remove all mar's and aar's neccesary, re-start
server, stop server, reinstall, start server.
If that works, try writing a test case and filing a jira. Or reply to the list
- I'm working on axis2 handlers at the moment and I may be able to confirm
the behavior. (got other probelms at the moment ;-) ) .
HTH,

Hi Brian,
Small clarification. OperationContext is not only for request-response
(In-Out). It is per MEP. But for the time being we support InOut and
In only MEPs.

Thanks Srinath, using the OperationContext I can persist object state
between the request and the reply.
Regards,
Brian.

Hi Brian;
Handlers are stateless across multiple invocations. You should store
the states in the OperationContext (msgctx.getOperationContext()). Get
back if that do not solve your problem.
Thanks
Srinath

Re: trouble redeploying handlers

thanks guys, figured it out....silly mistake on my behalf. I had an old
classname referenced from the modules.xml file within the .mar file.
Still unusual behaviour though, surely i should have gotten a
ClassNotFoundException as the class being referred to was no longer on
the system!!

hmmm , that can not be unless you have some files in commons lib , or the
lib that CCL pick up , I have test that and I don't have any problem , any
way pls try it again ,
1. do the changes
2. re-create mar file
3. re-deploy that
4. re-start the server
if you still have the problem pls create JIRA
Thanks,
Deepal

trouble redeploying handlers
Posted by Brian Shields <br...@geminga.it.nuigalway.ie>.
Hello,
I am having some trouble redeploying a handler .mar file in axis2. The
engine seems to have an old reference to the classes inside my module
and any changes i make are not being reflected when i repackage the
module and redeploy it. I am restarting the web server and it is still
referencing the older version of the classes!! Any ideas?
