Hello,

I have a servlet which is supposed to execute a shell command and display the output. The shell command is as follows and this is the output at the command line:

localhost:~#serctl ul show 2045
<sip:[email protected]>;q=1;expires=456778

However my servlet code which I have included below, only prints ";q=1;expires=456778". It leave out the line in the "<>". I suspect this is something to do with the tags. Can someone tell me how to fix this?

String[] command = { "serctl", "ul", "show", "2045" }; // Only change!

    Runtime runtime = Runtime.getRuntime();
    Process process = null;
    try {
      process = runtime.exec(command);
      BufferedReader in =
      new BufferedReader(new InputStreamReader(process.getInputStream()));

      // Read and print the output
      String line = null;
      while ((line = in.readLine()) != null) {
        out.println(line);
      }
    }
    catch (Exception e) {
      out.println("Problem with command");
    }

Many thanks in advance for the help,
Aisling.

You shouldn't change anything in the servlet program. However, you need to HtmlEncode the result when you feed it to the control that displays it on the page. You can use Server.HtmlEncode which will change the < > to &lg; &gt;.

Im sorry im new to java!!...I still don't understand.

Will I change it to something like:

line = Sever.HTMLEncode(in.readline());

Many Thanks,
Aisling.

You need to make that call in the ASP.NET code that calls the servlet and assigns the value to some web control (if I am understanding your scenario correctly).
