    <p>I'm running <code>JEE6</code> with <code>glassfish v3</code> on <code>NetBean6.9</code> and working on <code>RESTful web service</code>.</p> <p>I have jsp file which contains javascript function below.</p> <p>It basically read info from <code>HTML input fields</code> and convert to <code>JSON format</code>.</p> <p>Then with <code>onclick Ajax call</code>, <strong>attempt to send JSON string using HTTP PUT method</strong>. (i.e. I'm trying to <code>UPDATE</code> the db record using REST)</p> <p>For js framework I'm using is <code>Prototype1.7</code></p> <p>When I test the function below, it always return 404 thus "something went wrong" alert is displayed.</p> <p>According to my search Prototype above 1.5 version supports HTTP PUT/DELETE methods and to do so add <strong>_method</strong> to the request URL like what I'm doing:</p> <pre><code>var url = "/resources/inventory/" + invId + "?_method=PUT"; </code></pre> <p>This will create for instance:</p> <pre><code>http://localhost:8080/NoJSF/resources/inventory/123?_method=PUT </code></pre> <p>I looked at Firebug and console showing that the request is actually <strong>POST</strong>. Not sure but I believe this is because of Prototype using POST tunneling to achieve PUT method?</p> <p>Also even though Ajax is being called, my Java file with JAX-RS annotated witn @POST is not even being called (@GET version is working with separate data so this is the right file) since the first line of its method that spit message is not showing up so I suspect my Ajax statement has some bug or there is something beyond my thinking.. could anyone give me hint?</p> <pre><code>function protoAjaxPut() { //get all fields value and store into json var invId = document.getElementById("invIdField").value; var invName = document.getElementById("invNameField").value; //put info into JSON format var jsonInput = JSON.stringify(new Array(invName)); var url = "/resources/inventory/" + invId + "?_method=PUT"; new Ajax.Request(url, { method:'put', postBody: jsonInput, ContentType: 'application/json', onSuccess: function(transport) { var responseData = transport.responseText; document.getElementById('putResponseText').innerHTML = responseData; }, onFailure: function() { alert('something went wrong!')} }) }//end protoAjaxPut </code></pre>

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.
