    <p>I'm looking to try and make a java server that can accept GET and POST HTTP requests. Now I've managed to get the GET method to work. But I'm not managing to get the POST method to work. My server manages to read the Request Header but doesn't seem to read the body of the message. i.e what was posted. Here is the code:</p> <pre><code>int port = 1991; ServerSocket serverSocket = new ServerSocket(port); System.err.println("The Server is on and listening on port " + port); System.out.println(" "); while (true) { Socket ClientSocketConnection = serverSocket.accept(); System.err.println("We have established a connection with a client!"); System.out.println(" "); BufferedReader ServerInput = new BufferedReader(new InputStreamReader(ClientSocketConnection.getInputStream())); DataOutputStream ServerOutput =new DataOutputStream(ClientSocketConnection.getOutputStream()); String StringInput; int iCount = 0; int CountNull = 0; while ((StringInput = ServerInput.readLine()) != null) { System.out.println(StringInput); } </code></pre> <p>Now I simply display everything that is sent through the socket. But for some reason I just dont get the requests message body and I know the Body is sent because in chrome I have this:</p> <p><img src="https://i.stack.imgur.com/zawiI.png" alt="enter image description here"></p> <p>I'm not sure how to get that "Form Data". Any help would really be appreciated!!</p> <p><strong>UPDATE:</strong></p> <p>Here is the problem further narrowed down. From sends the HTTP request fine. With an HTTP POST method we have the request header a \r\n and then the message data. The problem is when my BufferedData variable <code>ServerInput</code> reads in the \r\n (empty line) it stops reading from the <code>ServerInput</code>. Anyway to fix this? </p>

    1. CODo you get a `Content-length` header? If so, then after reading an empty line (which indicates the end of the header section) read _Content-length_ number of bytes and convert them to a string. Your problem is maybe that there is no line ending at the end of your ServerInput and therefore `readLine()` waits for it forever.

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.
