xmlnodes is *assumed* to be in your base configuration for nodeMap to be
created properly
IF xmlnodes is nowhere to be found a NEW nodeMap IS created via
Map<QName, XmlNode> newNodeMap = new HashMap<QName, XmlNode>();
//assumptions xmlSchemaList is a set properly by constructor
//elementQName is set properly by constructor
xmlNodeGenerator = new XmlNodeGenerator(xmlSchemaList,
elementQname);
mainXmlNode = xmlNodeGenerator.getMainXmlNode();
//get the Queue from mainXmlNode
queue = xmlNodeGenerator.getQueue(mainXmlNode);
//put new mainxmlNode into newNodeMap and associate to elementQName
newNodeMap.put(elementQname, mainXmlNode);
//re-insert the new Map into configContext under 'xmlnodes'
configContext.setProperty(JsonConstant.XMLNODES, newNodeMap);
ELSE elementQname (passed in from XMLStreamReader) is searched within the
xmlnodes
IF elementQName is found in xmlnodes
//a queue is acquired from existing nodeMap created from xmlnodes referenced by
elementQName
xmlNodeGenerator = new
XmlNodeGenerator().getQueue(nodeMap.get(elementQname))
//if xmlnodes nodeMap exists but has NO elementQName entry then mainXmlNode
will be used:
//assumptions xmlSchemaList is a set properly by constructor
//elementQName is set properly by constructor
xmlNodeGenerator = new XmlNodeGenerator(xmlSchemaList, elementQname);
mainXmlNode = xmlNodeGenerator.getMainXmlNode();
//get Queue from mainXMLNode
queue = xmlNodeGenerator.getQueue(mainXmlNode);
//put new mainXmlNode into existing nodeMap and associate with 'elementQName'
nodeMap.put(elementQname, mainXmlNode);
//re-insert the new Map into configContext under 'xmlnodes'
configContext.setProperty(JsonConstant.XMLNODES, nodeMap);
reference the 4.2.0 branch of WS02 codebase:

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.
