java javascript json multidimensional-array jsonexception

I converted a normal JavaScript array (which is in one JSP page), did a JSON.stringify() to that array and passed it across to another JSP as a parameter. In the other JSP, I'm reading it using request.getParameter().

Now, while converting the string to a JSONArray, I'm getting an exception like this-

net.sf.json.JSONException: Missing value. at character 2 of [[\"111\", \"1.1.1.1\", \"111\", \"111\", \"111\"]]

This is how my String from request.getParameter() looks like-

[[\"111\", \"1.1.1.1\", \"111\", \"111\", \"111\"]]

What does net.sf.json.JSONException: Missing value. at character 2 of [[\"111\", \"1.1.1.1\", \"111\", \"111\", \"111\"]] mean? And how do I deal with it?

I figured it out. The reason it was throwing that exception was because it was expecting " instead of \" after [[. All I did was [[\"111\", \"1.1.1.1\", \"111\", \"111\", \"111\"]].replaceAll("\\\"", "\"").
