  • Lightweight Java reporting engine

    - by tuler
    I'm looking for a lightweight java reporting engine to be embedded in an applet application. My first option was Jasper Reports, but the jar is over 2Mb, a little too heavy (and too bloated) for my needs. I don't know if there is modular jasper distribution, with funcionalities split in several jars (like html rendering, pdf, excel, compilation, runtime, etc). I need to preview the report using Swing and print it. PDF export is a plus.

  • What's the fastest way to draw a Hello World in Java

    - by Mordan
    What's the fastest way to draw a Hello World on the screen as a GUI in Java, 1- by using the minimum number of classes. 2- with the least byte code executed 2- the JVM tweaks so when I double click on the Jar file in Windows, the Hello World appears in no time (assuming the Runtime is not already loaded).

  • Push alerts to notification tray app in Java

    - by Rich Anderson
    Hi - how do I push server alerts to tray apps in java without using xmpp or other heavy protocols? Do you recommend a way to accomplish this? I was planning to write an app which uses URLConnection on a server equipped with Comet but I doubt if that would work as the client requires a JS to be invoked and URLConnection is not a browser.. What is the best way to push instead of using a proprietary client-server approach?

  • How would someone implement mathematical formulae in java?

    - by Mohit Deshpande
    What I mean is like have to user input a string with multiple variables and get the value of those variable. Like a simple quadratic formula: x^2 + 5x + 10. Or in java: (Math.pow(x,2)) + (x * 5) + 10The user would then enter that and then the program would solve for x. I will be using the BeanShell Interpreter class to interpret the string as an equation. But how would I solve for x?

  • Java writes bad wave files

    - by Cliff
    I'm writing out wave files in Java using AudioInputStream output = new AudioInputStream(new ByteArrayInputStream(rawPCMSamples), new AudioFormat(22000,16,1,true,false), rawPCMSamples.length) AudioSystem.write(output, AudioFileFormat.Type.WAVE, new FileOutputStream('somefile.wav')) And I get what appears to be corrupt wave files on OSX. They won't play from Finder however using the same code behind a servlet writing directly to the response stream and setting the Content-Type to audio/wave seems to play fine in quicktime. What gives?

  • Why do people run Java GUI's on the Event Queue

    - by asmo
    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?

  • Java MessageDigest result does not stay constant

    - by user344146
    I've got this function for encrypting passwords in Java, but somehow when I call MessageDigest, it returns a different result every time even though I call it with the same password. I wonder if I am initializing it wrong somehow. public String encrypt (String password) { MessageDigest md = MessageDigest.getInstance("SHA-1"); md.reset(); md.update(password.getBytes(Charset.forName("utf-8")),0,password.length()); String res = md.digest().toString(); }

  • Why doesn't Java warn about a == "something"?

    - by Marius
    This might sound stupid, but why doesn't the Java compiler warn about the expression in the following if statement: String a = "something"; if(a == "something"){ System.out.println("a is equal to something"); }else{ System.out.println("a is not equal to something"); } I realize why the expression is untrue, but AFAIK, a can never be equal to the String literal "something". The compiler should realize this and at least warn me that I'm an idiot who is coding way to late at night.

  • Manually Increasing the Amount of CPU a Java Application Uses

    - by SkylineAddict
    I've just made a program with Eclipse that takes a really long time to execute. It's taking even longer because it's loading my CPU to 25% only (I'm assuming that is because I'm using a quad-core and the program is only using one core). Is there any way to make the program use all 4 cores to max it out? Java is supposed to be natively multi-threaded, so I don't understand why it would only use 25%.
