Body
I'm working on a school project and the following codes are an example provided for building the project (should work without any problem but not...). There was no compiling error but when I use telnet to test it the following message shows: <pre><code>java.io.StreamCorruptedException: invalid stream header: 56543130 at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:801) at java.io.ObjectInputStream.<init>(ObjectInputStream.java:298) at ThreadedDataObjectHandler.run(ThreadedDataObjectServer.java:41) </code></pre> Line 41 is <pre><code>ObjectInputStream in =new ObjectInputStream(incoming.getInputStream()); </code></pre> Here are my codes: <pre><code>import java.io.*; import java.net.*; import java.util.*; public class ThreadedDataObjectServer { public static void main(String[] args ) { try { ServerSocket s = new ServerSocket(3000); for (;;) { Socket incoming = s.accept( ); new ThreadedDataObjectHandler(incoming).start(); } } catch (Exception e) { e.printStackTrace(); } } } class ThreadedDataObjectHandler extends Thread { DataObject myObject = null; private Socket incoming; private String greeting="Hello!"; public ThreadedDataObjectHandler(Socket incoming) { this.incoming = incoming; } public void run() { try { ObjectInputStream in =new ObjectInputStream(incoming.getInputStream()); ObjectOutputStream out =new ObjectOutputStream(incoming.getOutputStream()); myObject = (DataObject)in.readObject(); System.out.println("Message read: " + myObject.getMessage()); myObject.setMessage("Got it!"); System.out.println("Message written: " + myObject.getMessage()); out.writeObject(myObject); in.close(); out.close(); incoming.close(); } catch (Exception e) { e.printStackTrace(); } } } class DataObject implements Serializable{ protected String message; public DataObject(){ message=""; } public void setMessage(String m){ message=m; } public String getMessage(){ return message; } } </code></pre> What I tried was to switch the order of statements <code>ObjectInputStream in=...</code> and <code>ObjectOutputStream out=...</code> but no luck. Please help...thanks.

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.
