Re: how to get soap header from stub in axis2

[Sanjiva Weerawarana]

A stub uses an operation client inside each method. The life of the
operation client is thus equal to the life of that method call. An
option would be to add a method to ServiceClient() to get the "last"
used operation client. Then one could get the last operation client,
get the appropriate message context from that and grab whatever info
needed.

We could implement this fairly trivially by making operationClient an
instance variable of ServiceClient and updating that whenever a new one
is created. ServiceClient is already declared to be not thread safe so
this should work ok (I think).

Sanjiva.

Re: how to get soap header from stub in axis2

[Deepal Jayasinghe]

Well in the current code base we do not have a way to get either
operation client or message context from the stub. I think we can
provide a way to access the current message context in the stub and from
that SOAP envelop and any other properties.

So please create a JIRA so that we will not forget the issue.

Thanks

Re: how to get soap header from stub in axis2

[Shaoguang Cong]

Deepal Jayasinghe has a paper mentioned that.
  http://www-128.ibm.com/developerworks/webservices/library/ws-soa-axis2-1/ 
  "With service clients you can only access SOAP body or the pay load. Of 
course you can add SOAP headers but you do not have a way to retrieve SOAP 
header from service client. For that you will need to use an operation client." 

  The problem is that the generated stub doesn't give a way to access the 
operation client.
  So from the client stub, one seems cannot get access to the operation client, 
messageContext or SOAPHeader. Anybody knows if there's a way to get such info 
from client handler?

Is there any way to do this?

RE: how to get soap header from stub in axis2

[Brennan Spies]

No, there's nothing sacred about generated code.ideally you're only supposed
to implement the Skeleton class, but if you need to do things with the SOAP
message itself, you'll have to do it in the Stub.

Yes I saw that in the generated Stub.  But is there a way to extract the
SOAP header without modifying the generated stub?  

My understanding was the stubs are not supposed to be modified?  I was
hoping to extract the header by using the generated stub methods.  I suppose
this will only be exposed if the soap-headers are explicitly declared in the
WSDL (which they are not in my case).
