I've got a project which requires both Jersey and Hibernate. Problem is they both use incompatible versions of a Jar file (asm.jar) under the covers. I've looked around Google and it appears that it's possible to get Hibernate to use another facility called Javassist, but when I try to follow the instructions it falls flat. I still get ...

I am writing a "simple" program to determine the Nth number in the Fibonacci sequence. Ex: the 7th number in the sequence is: 13. I have finished writing the program, it works, but beginning at the 40th number it begins to delay, and takes longer, and longer. My program has to go to the 100th spot in the series. How can I fix this so ...

Suppose there are three tables: Table A (ID, NAME) Table B (ID, NAME) Table A-B (A_ID, B_ID, Boolean_Property) and Table A and B are modeled by classes A and B as follows: public class A { private long id; private String name; // All the B's that belong to A where the boolean property is True Set<B> trueBSet; //...
I have created a panel on which a set of objects is drawn. Each of the object is added as a mouse event listener to the panel. As I know, after an event occurs the listeners are notified and the code might be (or is?) executed in several threads. Is it possible to attach a custom code that will be executed after all listeners finish exec...

Here is how static Executors.newCachedThreadPool is implemented in the standard Java library: public static ExecutorService newCachedThreadPool() { return new ThreadPoolExecutor(0, Integer.MAX_VALUE, ...
Hi guys, I'm attempting to mimic (or find a preexisting component) that mimics the zoom slider from Word 2007: There are two main differences between this component and a standard Java JSlider: Does not snap to ticks except at 100%, and snaps while you're sliding the bar rather than when you release mouse Slider is not linear the ...
I wrote some code that looks similar to the following: String SKIP_FIRST = "foo"; String SKIP_SECOND = "foo/bar"; int skipFooBarIndex(String[] list){ int index; if (list.length >= (index = 1) && list[0].equals(SKIP_FIRST) || list.length >= (index = 2) && (list[0] + "/" + list[1]).equals(SKIP_SECOND)){ r...
I like STL a lot. It makes coding algorithms very convenient since it provides you will all the primitives like parition, find, binary_search, iterators, priority_queue etc. Plus you dont have to worry about memory leaks at all. My only concern is the performance penalty of operator overloading that is necessary to get STL working. For ...

I'm trying to run a jar within a java program and capture its stdout. I want to do this to avoid the JVM startup cost every time the jar is run. What is the simplest way to do this? I started by modifying Java's JarClassLoader and adding a SecurityManager subclass to that to prevent system exits. The JarClassLoader is a subclass of URL...
When building a Java Applet are there any steps that can be made to prevent a user invoking internal methods? Theoretically most objects can be analysed and methods can be invoked on a client machine. In addition to obfuscation are there any other steps that can help prevent this? My situation is to secure a game where the top score i...
