Error parsing HTTP request header along with 400 bad request in browser

Question

My scenario is,

I have a text field with a button named as "Search", when I entered a value in the text field and click on search button, the value should write/written in existing JSON file. Please find the below code.

function search_criteria()
{
var inputData = document.getElementById("sel").value;
var fileDetails = 
{
    'fileName'  : 'sample.json',
    'fieldName' : 'field1',
    'inputValue' : inputData
}
$
.ajax({
    type : "GET",
    url : "/abc/rest/input_value/search_action",
    data : JSON.stringify(fileDetails),
    contentType : 'application/json',
    success : function(msgr) {
    },
    error : function(data) {
        alert("Inside error while adding input in search field"
                + data);
    }
});

}

Java code

@GET
@Path("/search_action")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response search_action(@Context HttpServletRequest request, 
JSONObject inputJsonObj)
        throws JSONException, FileNotFoundException, IOException {

    String relativeWebPath = "/TEMP/scenario_content/" + 
inputJsonObj.get("fileName").toString();
    String absoluteDiskPath = 
request.getServletContext().getRealPath(relativeWebPath);

    File file = new File(absoluteDiskPath);
    if(!file.exists())
    {
        file.createNewFile();
    }
    JSONObject json = new JSONObject();
    json.put(inputJsonObj.getString("fieldName"), 
inputJsonObj.getString("inputValue"));

    FileWriter fw = new FileWriter(absoluteDiskPath);
    fw.write(json.toString());

    return Response.status(Status.OK).entity("success").type(MediaType.APPLICATION_JSON)
            .header("X-Content-Type-Options", "nosniff").build();
}

I got the below error by using this code.

org.apache.coyote.http11.AbstractHttp11Processor 
process
INFO: Error parsing HTTP request header

DEBUG level.

Also I got 404 Bad Request in Browser console. Kindly help me to fix this issue.

404 is "not found", 400 is "bad request". So is it a 404 error, or a bad request error? — Jeremy Thille, Aug 02 '17 at 06:15
You give the code @Path("/search_criteria") but ajax call url : "/abc/rest/input_value/searchAction". Can you set DEBUG level for java log? It is written that error is logged in DEBUG. Also, take a look at the browser network debug tab to check your request. — wargre, Aug 02 '17 at 06:15

in the code that you are showing, the path for the Controller is @Path("/search_criteria") but in your ajax call your url is url : "/abc/rest/input_value/searchAction", so they don't macth and you get a 404.

I got the same error when I changed to /abc/rest/input_value/search_criteria – MoNa Aug 02 '17 at 06:42
Have you tried to write the url in the browser? Maybe is not an ajax problem. – Antonio314 Aug 02 '17 at 06:50
I have rectified the error by changing POST method in java code. Previously I have used GET method. – MoNa Aug 02 '17 at 13:44
But the value is not appended in the existing json file, even though I got 200 OK message in Browser console. – MoNa Aug 02 '17 at 13:49
