It would be easier if you use some library (such as Jackson) to build your JSON responses. wiki.fasterxml.com/JacksonHome –  Pavel Horal Jun 21 '13 at 8:41

This does not look like valid json, try the below to see if it then will send.

data = {
            "key": "job1"
        }

I am not sure, what do you want to do with line. url : "<c:url value="/"/>" + "getMessage.htm",

If this is nexted string value, try this single codes instead of double.

url : "<c:url value='/'/>" + "getMessage.htm"

c:url will get to the base location of the webapp so you don't have to do ../ each time you get further down the url path. It gets rendered by the JSP. –  david99world Jun 21 '13 at 8:40
