if xmlnode is already in the DOM sent to the client
then all he needs to do is grab the root node
then walk down to the xmlnode to reference the node he needs

Hi Jayanga,
Create a JIRA for the above issue and you are more than welcome to provide a
fix for it. IMO ServiceContext would be a good place to store nodeList.
ThanksShameera.

Hi Jayanga,
For the sake of performance, only generated node list for a service is the very
first time it gets a request. Then we save this nodelist against it service
QName. So you can safely move this nodelist to serviceConfiguration level then
the issue you mention will vanish. Or you can introduce a way to update nodeMap
by checking last update time of the service.
Thanks,Shameera.

Hi,
Yes. This is exactly my observation. Thanks for elaborating the above
implementation.
Here the 'nodeMap' is stored in the ConfigurationContext. Why it is stored in
ConfigurationContext instead of ServiceContext. I think, if we need to update
the 'nodeMap' when the services are redeployed, it should be stored in
ServiceContext.
Thanks,Jayanga.

IF elementQName is found in xmlnodes

reference the 4.2.0 branch of WS02 codebase:
https://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.2.0/dependencies/axis2/1.6.1-wso2v10/modules/json/src/org/apache/axis2/json/gson/GsonXMLStreamReader.java
does this conform to your observations?

Subject: json.gson : 'NodeMap' in ConfigurationContext doesn't get cleared with
service redeployment
From: [email protected]
To: [email protected]
Hi All,
I am trying out some samples with axis2 json.gson [1] implementation. In my
sample I have an Axis2 service which accept and sends json contents. According
to the json.gson implementation, it creates the 'NodeMap' in the first
invocation and sets it in the ConfigurationContext.
I made some changes to the json mappings in my service and simply redeploy the
service without restarting the server. While doing this I found out that
org.apache.axis2.json.gson.GsonXMLStreamReader failed to read the request.
While debugging the code found out that, this is happened by the un-updated
'NodeMap' in the ConfigurationContext.
Though my service get redeployed, the 'NodeMap' doesn't get updated. Once I try
to access the service it tries to parse the request with old 'NodeMap' and
fails. ConfigurationContext doesn't get updated/invalidated with service
redeployment.
So, shouldn't the 'NodeMap' be stored in a context like ServiceContext, which
get refreshed with service redeployment.
Can someone please help me to understand and solve the above issue.
