Parsing JSON data in Servlet

[gjain123]

Hi All,

I am passing json data to servlet as below:

	 Ext.Ajax.request({
	    url: CONTEXTPATH + "/ServletURL",
	    type: 'post',
	    jsonData :{
			record: sample,
			comments: text
                      }
	});

and trying to get that value in servlet but it does not seem to be working. I can see the data in firebug under POST tab and Content-Type is "applicatio n/json; charset=UTF-8".

The data that I can see on POST tab is as below:

{"record":{"key1":"value1","key2":"value2","key3":"value3","key4":"value4","key5":"value5"},"comments":"Testing"}

In servlet I tried to get the value using

request.getParameter("record")

and

request.getParameter("comments")

but everything is coming as null.

Please advice what I am doing wrong.

Thanks,
Gaurav

With jquery the send syntax would be

dataType : 'json',
data: { jsonData : JSON.stringify(jsondata)},

And servlet with

request.getParameter("jsonData")

Not sure what client library you are using there but maybe try

request.getParameter("jsonData")

.

You will only get a String representation of the json data not the individual json properties. You will need a json library (e.g Jackson) to parse the json.
