Using JSON to Serialize from JSP to JavaScript

Asked by WashoeCounty in Java Programming Language, Java Server Pages (JSP), JSON

Tags: Java, jsp, JavaScript, JSON, Serialize, dojo

I am using JSON to serialize a Java object so I can use it in a JavaScript file.  I am also using dojo, as you can see below.  

Sometimes I get an object error when I am trying to access the serialized parts of the object in the JavaScript file.  What would cause these type of errors?  I have used serializer.serialize and serializer.deepSerialize based on whether or not the object contains more objects.

//In the js
function loadControls(projectsId){
   dojo.xhrGet( {
      url: "ProjectsTools.jsp?action=getProjectByProjectsId&projectsId="+projectsId,
      handleAs: "json",
      sync: true,
       timeout: 5000, 
      load: function(response, ioArgs) {
          document.getElementById("projectName").value = response.projectName;
      },
      error: function(response, ioArgs) {
         return response;
      }
   });
}
 
//In the JSP
if (action.equals("getProjectByProjectsId")){
   Integer projectsId = Integer.parseInt(request.getParameter("projectsId"));
   projects = projectsManager.getProjectByProjectsId(projectsId);
   JSONSerializer serializer = new JSONSerializer();
   out.println(serializer.deepSerialize(projects));
}
