How could I create ObjectInputStream and use it indefinitely with Servlets?

Question

Hi All,
I would like to create the stream object between applet and server only once with urlConnection.openConnection() and use it to write objects to it indefinitely without reinstantiating it or getting another connection with urlConnection.openConnection() and repeatedly query for another input / output stream with servletOutputStream = new ObjectOutputStream (servletLinkup.getOutputStream()); How could this be done?

Dear vladimp,
The thing is, you need to ask good questions to receive good answers.Have you ever written a servlet vladimp? More specifically, have you ever written client - server code and have the two sides send objects to each other over the HTTP protocol?
This question is directed towards those developers who have done similar code and may have suggestions regarding this post.
What have you tried and how exactly has it failed for you?Quote from my post: "I would like to create the stream object between applet and server only once with urlConnection.openConnection() and use it to write objects to it indefinitely without reinstantiating it or getting another connection..." - that is, every time I want to write another object to the stream. Apparently whatever I tried didn't work, hence I'm posting here. Maybe someone with more servlet development experience would be willing to shed some light on this.
Why do you think the overhead of wrapping ObjectInput/OutputStreams
around the URL stream is large?Why do you believe I care if the overhead is large? My question is about maintaining a persistent connection to a servlet not overhead.
Have you made use of OutputObjectStream.reset()?This is actually a legitimate question (even though it's an ObjectOutputStream not a OutputObjectStream). The answer is YES I tried and NO it didnt' work. Could be that anything sent has to be followed up by a .flush() or/and a .close() to actually trigger the stream to send the object. At least according to some sources (I'm trying to verify this).
How about some sample code that reproduces the issue?URLConnection servletLinkup = urlConnection.openConnection();
servletOutputStream = new ObjectOutputStream (servletLinkup.getOutputStream());
Should be obvious for someone who did it before.
What is it about this problem that warrants a post to Advanced
Language Topics forum vs, say, Serialization forum?Testosterone driven guru java developers. Perhaps this could also go under the 'Java Servlet Technology' section as well, who knows, there's so many to choose from. I've actually gotten some very creative replies regarding this in other places. I can't say I didn't enjoy this post, however. 8^D. Thnx to all who have read the post.
