    <p>Is there any convenient way to read and parse data from incoming request.</p> <p>E.g client initiate post request</p> <pre><code>URLConnection connection = new URL(url).openConnection(); connection.setDoOutput(true); connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary); PrintWriter writer = null; try { OutputStream output = connection.getOutputStream(); writer = new PrintWriter(new OutputStreamWriter(output, charset), true); // true = autoFlush, important! // Send normal param. writer.println("--" + boundary); writer.println("Content-Disposition: form-data; name=\"param\""); writer.println("Content-Type: text/plain; charset=" + charset); writer.println(); writer.println(param); </code></pre> <p>I’m not able to get param using <code>request.getParameter("paramName")</code>. The following code</p> <pre><code>BufferedReader reader = new BufferedReader(new InputStreamReader( request.getInputStream())); StringBuilder sb = new StringBuilder(); for (String line; (line = reader.readLine()) != null;) { System.out.println(line); } </code></pre> <p>however displays the content for me </p> <pre><code>-----------------------------29772313742745 Content-Disposition: form-data; name="name" J.Doe -----------------------------29772313742745 Content-Disposition: form-data; name="email" abuse@spamcop.com -----------------------------29772313742745 </code></pre> <p>What is the best way to parse incoming request? I don’t want to write my own parser, probably there is a ready solution.</p>

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).
