Question

I have a servlet to which I am posting data from ajax(jquery) call.

$('form').submit(function() {
var URL = "ProjectHandler"; 
var dataString=$(this).serialize();
$.ajax({
       type: "POST",
       url: URL,
       data: dataString, 
      // dataType: json,
       success: function(data)
       {
           alert(data.error);

       }
     });
    return false; 
});

I have commented dataType beacause when I uncomment it, it doesnt make ajax call, rather, the form is submitted with default mode i.e. the servlet is loaded

JAR’s I have added to the project 1. json-lib-2.2.2-jdk15.jar 2. apache-commons-lang.jar 3. ezmorph-1.0.jar

first it threw exception filenotfound which was part of apache-commons package so included apache commons, after that I got exception of filenotfound which was part of ezmorph-1.0.jar, so I added that also. Now I am getting

java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory

Code in servlet doPost:

response.setContentType("application/json");
PrintWriter out = response.getWriter();

JSONObject json  = new JSONObject();
json.put("error", true);
json.put("errorDesc", "wrong title");
out.print(json);

I hope I have cleared the scenario, any help would be appreciated.

Thanks

It looks like you are missing the commons-logging.jar. Add it to your classpath.
