I'm very new to obfuscation and don't have a lot of experience with ant. Come someone provide me a way to obfuscate a regular Java application with ProGuard (or any other open source obfuscator). Currently I'm using NetBeans 6.5.1, and only see the obfuscation ability if I create a JAVA ME, and not a Java Application like I have. I've...
I am at a point where I need to take the decision on what to do when caching of objects reaches the configured threshold. Should I store the objects in a indexed file (like provided by JCS) and read them from the file (file IO) when required or have the object stored in a distributed cache (network, serialization, deserialization) We a...

Hi All, I have tried to find the answer to this question on both the Spring forum and by searching StackOverflow. I have found a lot of pages describing horrible architectures and asking for about the same thing as I do, but my intended usage is different so please bear with me :-) I have a Spring 2.5 project using annotation based for...
I'm using Swing for the first time to create a simple GUI. It consists of a JFrame upon which I have placed a single JButton which, when clicked, calls some other code which takes approx. 3 seconds to return. Just before the call to this code, in actionPerformed(), I want to update the text on the button to inform the user that processi...
I am using ObjectOutputStream to create a file of serialized objects. I then use an ObjectInputStream to with the readObject() method to get the objects back out of the file. It works great the first time. Meaning that if the file does not exist and I open it then append any number of objects, I can open the ObjectInputStream object a...
Am I just to blind to see the solution? sampleSum = 0; for(int x : sampleWeights) sampleSum += x; population = new int[sampleSum]; int z = 0; for(int i = 0; i < nsamples; i++) for(int j = 0; j < sampleWeights[i]; j++) { population[z] = i; z++; } Any help is appreciated! Thanks! ...
Hi, I'm developing an JSF web app on Tomcat, planning to use Seam in the near future, and I want to add compression of our web pages and resources (i.e. Javascript & CSS files). I'm aware of three methods to GZIP responses in a Java web : Use Ehcache GZIP filter: it's used in Appfuse, so it's probably solid and it checks if the user a...

I'm presently refactoring a JTable which displays a multitude of different types of data. The primary reason for this refactoring is that there a few ClassCastExceptions (the author/friend who wrote the code is off on hiatus), and I can't seem to find where these are originating from. Due to the large codebase, I'm at a loss as to where ...
Hello everyone, I am having some stackoverflow issues and hopefully someone can give me some insight into a non/less-recursive solution.

I'm currently looking at upgrading the logging mechanism in a medium-to-large-sized Java codebase. Messages are currently logged using static methods on a Debug class, and I have recommended switching from this to something like SLF4J or commons-logging. The application architect prefers that I encapsulate the dependency on SLF4J (possi...
