I am looking for your recommendations on data structures to
consider for use in a program for efficiency, etc. . . .  I have tens
of thousands of small text files that are the output of some analysis
algorithms.  (Their number may grow significantly in the future.)

I'm implementing a program which uses a specific protocol to
communicate with other clients, but I was wondering how to implement
the protocol itself (in a well structured way). I already have a class
which handles the serialization and sending and receiving of messages.

I am working on a system where we continually jump between native code
and java code.  I have a place where I use NewDirectByteBuffer in the
native code to create a data buffer I can use to pass data back and
forth from java.

Here is a schema generated from the DTD for JNLP 6.
It looks similar to XSD, but not quite. What is it?
<?xml version="1.0" encoding="UTF-8" ?>

I try to parse some XML results of PubMed (the largest biomedical
article database).
The document contains elements like this: <articletitle>[Virus and RNA

My curiosity about Hotjava now sated, what of Peter van der Liden? I recall
that he used to be pretty active on Usenet and quite a prolific author and
Java advocate.
As I recall he used to author the Java FAQ (which now 404's). I liked his

I am in a soup again :) I have a java class called SessionManager. As
its name implies, it keeps track of session.getAttribute and
session.setAttribute calls from a webserver (actually JSF + JBOSS
which is another nightmare :).

I need your help.
My web application does not support foreign language characters right
now. If I type in some chinease charanters in TITLE and save, it comes
back with garbage. While my database is UTF-8, the rest of the

I would like to check concurrency issues in java web application; like
all developers I did a System.out.println on the current thread:

Can anyone help me understand what the values in the system.out are?

On my machine, any desktop icon to launch Java Webs Start app fails
with a message about Java not being installed.
I discovered manually created shortcuts to the JNLP file would work.
I discovered  today that modifying the shortcut to use C:\Program

I am operating within Tomcat 6.  I use 'collector' singletons to build
complex trees of objects from database queries.  These singletons rely
on a pool of connections to various data sources, which are made
available via a 'connection pooling' singleton like this:

When a .jar file is downloaded via Java WebStart,
where is it downloaded?
I use Windows XP.
  thanks,

This is the sort of question that I hope won't start an unhappy
discussion, but I wanted to know whether there are any well accepted
tests comparing java to C++ (or C) for doing extensive number
crunching (e.g. multiplying 100,000 vectors in three space by various

I am trying to use a Pattern to match certain strings in error
messages in our application.  We are delimiting them using the
following notation, {0}, {1}, etc.  I am trying to use String's
