Improve Json support in Axis2 with google-gson
----------------------------------------------
Key: AXIS2-5270
URL: https://issues.apache.org/jira/browse/AXIS2-5270
Project: Axis2
Issue Type: Improvement
Components: json
Affects Versions: 1.7.0
Reporter: Shameera Rathnayaka
Assignee: Shameera Rathnayaka
Fix For: 1.7.0
There are two ways that xml string can be converted into JSON string,
Badgerfish and Mapped . Current Axis2 with JSON module completely supports
Badgerfish convention[1] while partialy supports Mapped convention[1] as Mapped
formatted JSON with namespaces are not supported in Axis2. Therefore if the
client side java-script code needs to talk with java service which is deployed
in Axis2, it should be sent as Badgerfish convention. It is cumbersome to
generate Badgerfish convention of JSON string again and again to call services
if there is no xml representation string in client side.
If java script client can send JSON object to relevant java service in Axis2,
defining service and operation in request url, without doing any modifications
to JSON objects, then it would be very helpful for Java-Script users at client
side.
According to the thread in the mailing list, which discussed $subject we have
two approaches. i have summarized those two approaches as below.
1. Store json inputstream in message context at the message builder while
putting dummy SOAPEnvelop to the message context, and using google-gson process
it inside the message receiver
2. Preserve the requirement that a message must have a well defined SOAP
infoset and use a trivial representation similar (or identical) to what we use
for plain text. This has the advantage that it is more in line with the rest of
the Axis2 architecture,
or
another option is to write an xmlstream reader/writer implementation to
parse the json stream. And provide that xml stream implementation to Axiom.
