I want to pass json values to the servlet to handle the request.

In client side, i could made the object with special character such as "&" .

I have given the input as 

"<h3>Welcome to ERP your name is #NAME#</h3>\n\n<h3>&nbsp;</h3>\n"

I retrieve the value from the json object by using 

request.getParameter("jsonVal")

by calling like this, the json value after the "&nbsp" , not taken by the servlet. The output is

"\"<h3>Welcome to ERP your name is #NAME#</h3>\\n\\n<h3>

and shows the error as:

org.json.JSONException: Unterminated string at character 206

After getting request.getParameter("jsonVal") , try on a JSON Viewer and identify what is the special character. Carriage return+new line has issues with JSONTokener, so you can trim it if possible and work with it.
