Invoking a Handler specific to a operation in axis2

[Narendra Kadali]

Hi All,
I am using Axis2 for my webservices creation. I creates some handlers for my webservices.


I don't need to invoke this handler for every oprations.

How can specify it

For example for create user i will user a enp as http://localhost:8080/axis2/services/createUser
and for updateUser i will invoke http://localhost:8080/axis2/services/updateUser.
For each invokatioon hadlers must be different.
Can any one give any suggestions on this regards.
Thanks,
Narendra

Hi Narendra,

Following is an excerpt taken from IBM documentation on SOAP Message Handlers using JAX-WS. As you mentioned Axis2, I presume you are using JAX-WS based web services.

To use handlers with your server application, you must set the @HandlerChain annotation on either the service endpoint interface or the endpoint implementation class, and provide the associated handler chain configuration file. Handlers for the server are only configured by setting the @HandlerChain annotation on the service endpoint implementation or the implementation class. The handler classes must be included in the server application EAR file.

Thanks for your reply.

What you mentioned here is really not necessary anotation... . I am using axis2 framework. I have to mention it in descriptor files. How to mentione in descriptor files I dont' know.

Hi Narendra,

But, it is same. Remember Axis2 implements JAX-WS!

I outline steps to configure SOAPHandler.

1. Write your SOAPHandler class implementing javax.xml.ws.handler.soap.SOAPHandler (unless you want to use logical handler)
2. Write handler chain configuration file and name to something like handchains.xml.
<handler-chains xmlns="http://java.sun.com/xml/ns/javaee"> <handler-chain> <service-name-pattern xmlns:ns1="http://abc.com/">ns1:*</service-name-pattern> <handler> <handler-class>Your qualified handler class goes here</handler-class> </handler> </handler-chain> </handler-chains>
3. For simplicity, place the file in the same package as your Handler class created in step 1.
4. In your end point implementation class, point to handler chain configuration file using

@HandlerChain(file="handchains.xml")

That's it!
