As part of my research I have created this huge java distributed system
for calculations.
The system is composed of a single "Sender" which sends jobs to a farm
of "Calculators" running on about 1000 different host machines. The

Consider a doubly-linked list holding a handful of nodes.  If the list
is cleared by nulling the head and tail references, is the GC
intelligent enough to dispose of all of the nodes?  For example, the
first node will no longer be referenced by the list, but it will be

So, I am trying to use a class as a Singleton inside AXIS. The
deployment descriptor has a scope qualifier for "application" which,
per documentation will accomplish this.
However, the class needs to also be able to work as an internal API to

I'm looking at the HelloWorld program
class HelloWorld {
  public static void main(String args[]) {
     System.out.println("Hello World");

could anyone please recommend some Journals related to Java Sound API.

I have a large tomcat/j2ee application that exists on 16 instances of
tomcat spread out across 9 server.  My problem (as you can probably
guess) is that
deployment of new code to all of these instances takes an extremely

Is there an idiom or pattern for creating two objects (a and b) of two
different classes A and B, such that A contains a reference to b and B
contains a reference to a. Should I pass it through a constructor? In
that case, when creating A, I cannot give the constructor a ...

Does anybody have a good word to say about generics in J2SE 5.0? I can't
help thinking it's a sledgehammer to crack a nut. Casting into and out
of collections wasn't such a big deal. Sure type-safety is important,
but the implementation is intrusive and ugly (aesthetics seem ...

Lets say I create a Vector that has class cast of holding Strings. I then
store that Vector to disk via ObjectStreams and FileStreams.
When I retrieve the Vector later. Will the Class casting survive the storage
process?

I've heard that PNG files have the capability of storing sufficient
information to represent an entire animation, much like an animated GIF does
today but without the copyright/patent issues that GIFs represent.
Are there actually any animated PNGs in existence? If so, how could I ...

I am experiencing problems when trying to communicate with a TCP socket
based application that does not always append a <CR> at the end of the data
and so cannot use readLine on a BufferedInputStream.
I have tried using a simple read in to a char array but have found that

I build a base class to read and write private fields of sub-classes,
but bursts IllegalAccessException.
public class BaseClass{
public void read(){

I am thinking whether is that possible (and how to do it) to set the
Xmx at run time?
The reason is:
Since I'd like to distribute the .exe executable rather than the .jar
