I need to hold my request in the server until new data comes.I am using the Tomcat 6 as my web server . So this is my JQuery code, <pre><code>function sendMessage() { var message = $("#message").val(); $.ajax({ type: "POST", cache: false, url: "sendMessage.html", data: "message=" + message, dataType: "html", success: function(response) { }, error: function(e) { //alert('Error: ' + e); }, }); } function startLongPolling(){ $.ajax({ type: "POST", cache: false, url: "LongPoll.html", dataType: "html", success: function(response) { if(response != null && response !="" && response !="null") $("#sucess").html(response); }, error: function(e) { //alert('Error: ' + e); }, complete: function(e) { startLongPolling(); }, }); } </code></pre> My java code will be , <pre><code>@RequestMapping(value = "LongPoll.html", method=RequestMethod.POST ) public @ResponseBody String longLongPolling(HttpSession session) { String sessionId = session.getId().toString(); AgentState agentState = ApplicaionManager.agentDetail.get(sessionId); String message = null; if(ApplicaionManager.agentDetail.containsKey(sessionId)){ while(true){ if(agentState.isStateChange() == true){ message = agentState.getMessage(); if(message != null) agentState.setStateChange(false); System.out.println("Break for session "+sessionId+" due to Agent State changed"); break; } try { Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } } } System.out.println("While exited for session"+sessionId); return message; } </code></pre> But there is a <code>continous request sent to server</code> for every 11 seconds . I don't know how it is possible. I have checked this with chrome developer tools. <img src="https://i.stack.imgur.com/pEvGw.png" alt="enter image description here"> Hope our stack users will help me.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
