    <p>I try to use the library <strong><a href="http://www.jcraft.com/jsch/" rel="nofollow">JSch - Java Secure Channel</a></strong> make an ssh connection in my Android app, it works.</p> <p>Now I would like to execute a command and retrieve the result.</p> <p>I tried several methods that works best is this. However, this method works only in part, because for some reason I can not explain, my program stops at the end of my while loop, yet I'm the result of the command that appears in my log.</p> <p><strong>Here is my code :</strong> </p> <pre><code>public static String executeRemoteCommand(String username, String password, String hostname, int port) throws Exception { JSch jsch = new JSch(); Session session = jsch.getSession(username, hostname, port); session.setPassword(password); // Avoid asking for key confirmation Properties prop = new Properties(); prop.put("StrictHostKeyChecking", "no"); session.setConfig(prop); session.connect(); Channel channel = session.openChannel("shell"); channel.connect(); DataInputStream dataIn = new DataInputStream(channel.getInputStream()); DataOutputStream dataOut = new DataOutputStream(channel.getOutputStream()); // send ls command to the server dataOut.writeBytes("ls\r\n"); dataOut.flush(); // and print the response String line = dataIn.readLine(); String result = line + "\n"; while ((line = dataIn.readLine()) != null) { result += line + "\n"; Log.i("TAG", "Line: "+line); } dataIn.close(); dataOut.close(); channel.disconnect(); session.disconnect(); return result; } </code></pre> <p>Does anyone else have a better way to run a command sheel with JSch?</p> <p>Thank you in advance !</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.
