Is it possible to create a simple server in Java that returns a response based on a given key?
So it would be a simple program, that stores a hashmap and returns the result based on a key provided by the client.
What would be the fasted implementation, to have it over HTTP or a socket? The client will be a web based application.
I have a neural network written in Java which uses a sigmoid transfer function defined as follows:
private static double sigmoid(double x)
{
return 1 / (1 + Math.exp(-x));
}
and this is called many times during training and computation using the network. Is there any way of speeding this up? It's not that it's slow, it's just that it is used a lot, so a small optimisation here would be a big overall gain.

In Java, to create and show a new JFrame, I simply do this:
public static void main(String[] args)
{
new JFrame().setVisible(true);
}
However, I have seen many people doing it like this:
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
public void run()
{
new JFrame().setVisible(true);
}
});
}
Why? Are there any advantages?

I'd like to merge 2 XML streams (strings) in Java, necessarily by XSLT (that I could change the transformation), but the problem is that the XMLs come as a string. There are many examples, but through the files.
Can this be done without saving them in files?
Thanks.
In Java, is there any way to create an instance of any class that extends abstract class A, inside a member method of class A? Classes that extends abstract class A will return their instances with this method, but i don't want to implement same method in all subclasses with a "return this();" kind line.

Hi, would it be possible to bind a Java application to a Cocoa graphical interface?
I'm working in Eclipse right now, on my mac, and am wondering if Interface Builder could be used to construct a new interface so that I don't have to look at Swing all day.
Any ideas/suggestions? Thanks!
I'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods.
I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances.
What's the recommended way of doing this?
I am trying to parse a string which in JSON format only that keys are not enclosed in quotes. I can very well parse this string in Javascript, but can not find a Java API which will help me parse this. All the APIs I tried assumes strict JSON format.
Can anyone suggest a library which has an option to parse this, or a whole new approach to the problem (say like use regex instead) ?

What are the things in the language or the API that you don't like or would design differently?
I'm writing a program that uses scp to copy files in a bigger java program. As it stands now, the program freezes up while the scp is copying the file, which can take a few minutes, so I'd like to be able to display the progress of the scp or at the very least get the terminal window with the scp progress to show up! Any suggestions?
Hi,
Does anyone know a library to compare addresses in Java ?
Something that would give equality on addresses, written in different ways.
For example, it should recognize that
"22 Acacia Avenue" and "22 acacia av."
is the same address.
Of course, this can escalate a lot, that's why i'm asking.
Thanks in advance.
