If I'm understanding you properly, you want something like that: <pre><code>import java.util.*; import java.io.*; class StreamGobbler extends Thread { InputStream is; String type; OutputStream os; StreamGobbler(InputStream is, String type) { this(is, type, null); } StreamGobbler(InputStream is, String type, OutputStream redirect) { this.is = is; this.type = type; this.os = redirect; } public void run() { try { PrintWriter pw = null; if (os != null) pw = new PrintWriter(os); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line=null; while ( (line = br.readLine()) != null) { if (pw != null) pw.println(line); System.out.println(type + ">" + line); } if (pw != null) pw.flush(); } catch (IOException ioe) { ioe.printStackTrace(); } } } public class GoodWinRedirect { public static void main(String args[]) { if (args.length < 1) { System.out.println("USAGE java GoodWinRedirect <outputfile>"); System.exit(1); } try { FileOutputStream fos = new FileOutputStream(args[0]); Runtime rt = Runtime.getRuntime(); Process proc = rt.exec("java jecho 'Hello World'"); // any error message? StreamGobbler errorGobbler = new StreamGobbler(proc.getErrorStream(), "ERROR"); // any output? StreamGobbler outputGobbler = new StreamGobbler(proc.getInputStream(), "OUTPUT", fos); // kick them off errorGobbler.start(); outputGobbler.start(); // any error??? int exitVal = proc.waitFor(); System.out.println("ExitValue: " + exitVal); fos.flush(); fos.close(); } catch (Throwable t) { t.printStackTrace(); } } } </code></pre> I found this piece of code in: <a href="http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html?page=4" rel="nofollow noreferrer">JavaWorld</a> sometime ago when I was looking for a similar solution to wrap system calls to some exe files. My code has evolved a bit since then, but I think is a good example.

Guidance

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.
