Be sure that all the objects stored in the
Vector or Hashtable are serializable.
If not, this will fail. This is what most people have a
problem with...

Absolutely! In J2SE, you can use functionality provided by streams...

You can create a new socket like this:

Socket soc_ClientConnection = new Socket("www.ThisIsMyClient.com", 12345);

This socket can be used to create a stream; it must be defined as an input or output stream like so:

OutputStream os_SocketStream= soc_ClientConnection.getOutputStream();


The getOutputStream() method returns an output stream. The ObjectOutputStream has methods which allow for the writing of serializable objects to this output stream. NOTE that the object must implement Serializable! A vector does implement this interface if I'm not mistaken...


ObjectOuptutStream oos_WriteObjectStream = new ObjectOutputStream(os_SocketStream);


Now, you can use oos_WriteObjectStream's writeObject() method to write objects such as vectors to the output stream. Use readObject() on the other client to reassemble the stream into a meaningful object.

See the API for more information about these methods... I'm writing this in a hurry so I may have left something out!

Hope this helps!
