    <p>I am passing the following JSON object from a .jsp page to a java servlet using JSON.stringify and JQuery.ajax():</p> <pre><code>{"bin":[{"binId":"0","binDetails":[{"productCode":"AU192","qty":"4"},{"productCode":"NE823","qty":"8"}],"comments":"store pickup"},{"binId":"1","binDetails":[{"productCode":"AF634","qty":"2"}],"comments":""},{"binId":"2","binDetails":[{"productCode":"QB187","qty":"3"}],"comments":"international shipping"},{"binId":"3","binDetails":[{"productCode":"AF634","qty":"2"},{"productCode":"QB187","qty":"2"}],"comments":""}]} </code></pre> <p>This is the code in my java servlet:</p> <pre><code>StringBuffer strBuffer = new StringBuffer(); String line = null; try { BufferedReader reader = request.getReader(); while((line = reader.readLine()) != null){ strBuffer.append(line); } } catch (Exception e) { } try { JSONObject jsonObj = new JSONObject(new JSONTokener(strBuffer.toString())); // I call a method here and pass jsonObj } catch (Exception e) { } </code></pre> <p>In the method to which I pass jsonObj I am using jsonObj.length() to find out how many items are in jsonObj and it tells me 1, which in this case I would have expected 3. I even tried this:</p> <pre><code>JSONObject bins = jsonObj.get("bin"); bins.length(); </code></pre> <p>which told me jsonObj.get("bin") was not a JSONObject. Is my data formatted incorrectly before I pass it from my .jsp or am I using the JSONObject in my java servlet incorrectly? How do I access the values in the JSONObject?</p>

    1. COIt looks like 'bin' is an array, not an object.

    2. COUm. Ok but isn't it an array of objects?

    3. COYes it is an array of objects. But, in your second code example, you get the array and then try to store it in an object of type JSONObject.

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.
