  • Installer/packager for a Java application for Ubuntu and SuSE

    - by Dan
    I have a Java application complied to a collection of jars that I want to make installable on Ubuntu and SuSE. I Want the installer to be able to check for the JRE, register a file association and be able to load a website on un-install. I understand Ubuntu and SuSE are based on different architectures, so is there a consistent way to do this? Does anyone have an advice on utilities to use or guides to read to help me achieve what I'm trying to do.

  • Java - Problem with the classpath on Eclipse.

    - by Amokrane
    I'm trying to recompile a project I've been working on and I keep getting an error message when trying to load a property file: The system cannot find the path specified. I guess this has to do with the classpath. But I've added the path to the file in Properties- Java build path- Libraries (external class). I also checked the .classpath file generated by eclipse, and the path is really there! Why isn't Eclipse looking at the right path?

  • Java: Finding objects in collections.

    - by Jake
    This problem occurs over and over. I have some complicated object, such as a Cat, which has many properties, such as age, favorite cat food, and so forth. A bunch of Cats are stored in a Java Collection, and I need to find all the Cats that are aged 3, or those whose favorite cat food is Whiskas. Surely, I can write a custom method that finds those Cats with a specific property, but this gets cumbersome with many properties; is there some generic way of doing this?

  • How does Java pick which method to call?

    - by Gaurav
    Given the following code: public class Test { public void method(Object o){ System.out.println("object"); } public void method(String s) { System.out.println("String"); } public void method() { System.out.println("blank"); } /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub Test test=new Test(); test.method(null); } } Java prints "String". Why is this the case?

  • Java: thread-safe RandomAccessFile

    - by Folkert van Heusden
    Hi, After some serious googleing I found out that the RandomAccessFile-class is not thread-safe. Now I could use one semaphore to lock all reads and writes but I don't think that performs very well. In theory it should be possible to do multiple reads and one write at a time. How can I do this in Java? Is it possible at all? Thanks!
