Questions re interceptor to insert XML into SOAP body

[Andrew Hart <ah...@akimeka.com>]

Hello all, 

 

I am using JBoss AS 6.x (the newest version I am allowed to use) and
that comes bundled with CXF 2.3.1.

 

I am fairly new to CXF and to web services in general.  I have a web
service with two operations,  the first to request data which posts a
message to a JMS queue where it is picked up by a message driven bean
that does a long running db query and builds some tables.  The second
takes a request number issued by the first and uses it to check for
results, which are then delivered if ready.

 

Instead of having the message driven bean build data base  tables which
I then have to read into java objects and get marshaled into XML for the
response, I would like to have it instead just go ahead and pre-marshal
them into XML and store that in the database instead.

 

Then, when the results are requested, I would like to fetch the XML from
the database and insert it into my SOAP response body as the payload.
This would simplify my database tables, since the results of different
requests could all be stored in the same table as XML, and should make
my response much faster for the second operation.

 

My questions:  I am assuming that I would need to disable the normal
interceptor that does this marshaling of the response and/or replace it
with my own that would insert the pre-marshaled payload from the
database.  Does anyone have any examples on hand of doing this?

 

Also, what is the purpose of the
SoapMessage.ASYNC_POST_RESPONSE_DISPATCH key that can be set to true or
false?   Is there some sort of already built in server side asynchrony
that I am not taking advantage of?

Hi,

Can you try to look at the JAXWS Dispatch API[1]?  
It could be more easy to deal with the XML message with this API.
