    <p>I need to send a mail with jsp, but the page itself mustn't reload. The whole implementation is working fine when reloading on the POST-event, but adjusting the code to work with ajax breaks it. It seems that the jsp-Code within the index.jsp is not executed, when the ajax event is triggerd. I am gonna show some snippets: </p> <p>index.jsp</p> <pre><code> &lt;% String result = "=("; String to = request.getParameter("rec_mail"); if(to != null) { String from = request.getParameter("sendermail"); String host = "mailserver"; Properties properties = System.getProperties(); properties.setProperty("mail.smtp.host", host); Session mailSession = Session.getDefaultInstance(properties); try{ MimeMessage message = new MimeMessage(mailSession); message.setFrom(new InternetAddress(from)); message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); message.setSubject("Feedback"); message.setText(request.getParameter("feedbackinput")); Transport.send(message); result = "Sucess!"; }catch (MessagingException e) { e.printStackTrace(); result = "failed!"; } } out.println(request.getParameter("sendermail")); out.println(result); %&gt; &lt;input id="bsend" class="fbutton" type="submit" name="send" value="Send" onclick="loadContent()" style="float:right; width:18%; height:35%;" &gt; </code></pre> <p>ajax.js</p> <pre><code>var xmlhttp function loadContent() { xmlhttp=GetXmlHttpObject(); if (xmlhttp==null) { alert ("Your browser does not support Ajax!"); return; } var url="./index.jsp"; xmlhttp.open("post",url,true); xmlhttp.send(null); xmlhttp.onreadystatechange=getOutput; } function getOutput() { if (xmlhttp.readyState==4) { alert("Message sent!"); } } function GetXmlHttpObject() { if (window.XMLHttpRequest) { return new XMLHttpRequest(); } if (window.ActiveXObject) { return new ActiveXObject("Microsoft.XMLHTTP"); } return null; } </code></pre> <p>(just showing the relevant parts, everywhere)</p> <p>I get the alert-message, but no mail is sent ... I hope it is clear, what I am trying to do..</p> <p>Thank you!</p> <p>Best regards</p>

    1. COinstead of alert("message sent");, you can write alert(responseText); as you have printed e.printstacktrace(), then if an error comes than it will be there

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
