    <p>I have a JSON string in my javascript, I need to send this to a java class. Can I use a plain java class or is it necessary to use a servlet?</p> <p>Also, How can I parse the JSON data?</p> <p>My JSON data is of the following format:</p> <pre><code> var details= { "CustomerDetails": [{'name':'Amy','age':'23'}, {'name':'Amj','age':'25'},{'name':'Amg','age':'27'}]}; </code></pre> <p>I send the json string like this:</p> <pre><code> var jsonText = JSON.stringify(details); $.post('ServletClass', jsonText); </code></pre> <p><strong>WEb.xml:</strong></p> <pre><code>&lt;servlet&gt; &lt;servlet-name&gt;ServletClass&lt;/servlet-name&gt; &lt;display-name&gt;ServletClass&lt;/display-name&gt; &lt;servlet-class&gt;java.files.ServletClass&lt;/servlet-class&gt; &lt;load-on-startup&gt;1&lt;/load-on-startup&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;ServletClass&lt;/servlet-name&gt; &lt;url-pattern&gt;/ServletClass&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; </code></pre> <p><strong>On my servlet side:</strong> I try to do a system.out.println, but get nothing, is the transfer even happening properly</p> <pre><code>package XXXX; import javax.servlet.*; import javax.servlet.http.*; import java.io.IOException; import java.files.JSONObject; import java.files.JSONSerializer; public class ServletClass extends HttpServlet { public void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException { } public void doPost(HttpServletRequest request,HttpServletResponse response)throws ServletException, IOException { // doGet(request, response); //JSONArray arrayObj = new JSONArray(); JSONObject jsonObj = new JSONObject(jsonText); JSONArray the_ json_array = jsonObj.getJSONArray("CustomerDetails"); System.out.println("FINALLY HERE"); } } </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.
