I have updated my ant build.xml file to include a new file and a new folder. After creating the .jar I check if they exist in the jar by 'unzip\extract', and they are there. But when executing the .jar neither the folder or the file gets extracted. Am I missing a step? ...
In certain unknown situations selenium does not detect that a page has loaded when using the open method. I am using the Java API. For example (This code will not produce this error. I don't know of an externally visible page that will.): Selenium browser = new DefaultSelenium("localhost", 4444, "*firefox", "http://www.google.com"); bro...
I'm trying to build a better username/password field for my workplace and would like to be able to complain when they have their caps lock on. Is this possible? And if so I'd like to have it detected before the client types their first letter. ...
I have searched for such a plugin but haven't found any. I need a facility to "tag" my java files. Similar to tagging on stackoverflow. I want to be able to group my files based on projects/tasks I wam working on. Mylyn helps a little but it dynamically changes the context (list of resources associated with a task) based on various fact...
I'm using jmockit for unit testing (with TestNG), and I'm having trouble using the Expectations class to mock out a method that takes a primitive type (boolean) as a parameter, using a matcher. Here's some sample code that illustrates the problem. /******************************************************/ import static org.hamcrest.Match...
In Java, I have a String and I want to encode it as a byte array (in UTF8, or some other encoding). Alternately, I have a byte array (in some known encoding) and I want to convert it into a Java String. How do I do these conversions? ...
Does the Java virtual machine ever move objects in memory, and if so, how does it handle updating references to the moved object? I ask because I'm exploring an idea of storing objects in a distributed fashion (ie. across multiple servers), but I need the ability to move objects between servers for efficiency reasons. Objects need to b...
I'm running the jdepend maven plugin on my project and whether I run "mvn site:site" or "mvn jdepend:generate" the report that gets generated says "There are no package used." There are no errors in the maven output. Other plugins (cobertura, findbugs, etc.) run fine. My pom is configured like this: <reporting> <plugins> <p...
I'm looking for a wizard library/framework for Java, but it seems all the ones I can find are abandoned and/or lacking in enough documentation to use quickly. Here's the ones I've found, and all appear to be no longer maintained. Java Wizard Framework SwingLabs Wizard Swing Wizard Framework I tried using SwingLab's Wizard, but I ran ...
I do not mean the compile errors because I made a syntax mistake or whatever. In C++ we can create compile time errors based on conditions as in the following example: template<int> struct CompileTimeError; template<> struct CompileTimeError<true> {}; #define STATIC_CHECK(expr, msg) { CompileTimeError<((expr) != 0)> ERROR_##msg; (void)...
The scenario is this We have two applications A and B, both which are running in separate database (Oracle 9i ) transactions Application A - inserts some data into the database, then calls Application B Application B - inserts some data into the database, related (via foreign keys) to A's data. Returns an "ID" to Application A Applicat...
Hi, quick question: my customer has a situation where he has his database with a varchar field and the corresponding jdbc code is storing/retrieving a boolean. I guess that the boolean values false and true are going to be translated to "0" and "1" but I would like to have a confirmation of this (I can't find the precise behavior speci...

I just learned about how the Java Collections Framework implements data structures in linked lists. From what I understand, Iterators are a way of traversing through the items in a data structure such as a list. Why is this interface used? Why are the methods hasNext(), next() and remove() not directly coded to the data structure impleme...
On my current project, we've been using Struts 1 for the last few years, and ... ahem ... Struts is showing its age. We're slowly migrating our front-end code to an Ajax client that consumes XML from the servers. I'm wondering if any of you have migrated a legacy Struts application to a different framework, and what challenges you faced ...
I am writing a simple checkers game in Java. When I mouse over the board my processor ramps up to 50% (100% on a core). I would like to find out what part of my code(assuming its my fault) is executing during this. I have tried debugging, but step-through debugging doesn't work very well in this case. Is there any tool that can tell ...

I have 3 PDF documents that are generated on the fly by a legacy library that we use, and written to disk. What's the easiest way for my JAVA server code to grab these 3 documents and turn them into one long PDF document where it's just all the pages from document #1, followed by all the pages from document #2, etc. Ideally I would like...
