I just saw a comment of suggesting J#, and it made me wonder... is there a real, beneficial use of J# over Java? So, my feeling is that the only reason you would even consider using J# is that management has decreed that the company should jump on the Java bandwagon... and the .NET bandwagon. If you use J#, you are effectively losing t...
Is it just me or are most colleges teaching Java instead of C++ these days? I feel like I've been missing out with having zero classes teach or use C++ at all....
I've found many sources that talk about the automated Eclipse PDE process. I feel these sources don't do a good job explaining what's going on. I can create the deployable package, in a semi-manual process via the Feature Export. The automated process requires knowledge of how the org.eclipse.pde.build scripts work. I have gotten a...
Is anyone successfully using the latest 64-bit Ganymede release of Eclipse on Windows XP or Vista 64-bit? Currently I run the normal Eclipse 3.4 distribution on a 32bit JDK and launch & compile my apps with a 64bit JDK. Our previous experience has been that the 64bit Eclipse distro is unstable for us, so I'm curious if anyone is using i...
I am running a Tomcat application, and I need to display some time values. Unfortunately, the time is coming up an hour off. I looked into it and discovered that my default TimeZone is being set to: sun.util.calendar.ZoneInfo[id="GMT-08:00", offset=-28800000,dstSavings=0,useDaylight=false, transitions=0,lastRule=null] Rather...
On a recent JAVA project, we needed a free JAVA based real-time data plotting utility. After much searching, we found this tool called the Scientific Graphics Toolkit or SGT from NOAA. It seemed pretty robust, but we found out that it wasn't terribly configurable. Or at least not configurable enough to meet our needs. We ended up dig...
How should I load files into my Java application?...
At work we are currently still using Junit3 to run our tests. We have been considering switching over to Junit4 for new tests being written but I have been keeping an eye on TestNG for a while now. What experiences have you all had with either Junit4 or TestNG and which seems to work better for very large numbers of tests. Having flexibi...
I 'm currently investigating the different styles of AOP in Java and I started with AspectJ. I try to get a good view on the different styles: weaver proxy any others Do you know a good tutorial or technology article about the different frameworks and techniques?...
I'm going to start a new project - rewriting an existing system (PHP + SQL Server) from scratch because of some very serious limitations by design. We have some quite good knowledge of SQL Server (currently we're using SQL Server 2000 in existing system) and we would like to employ its newer version (2008 I guess) in our new project. I...
I was hoping someone could help me out with a problem I'm having using the java search function in Eclipse on a particular project. When using the java search on one particular project, I get an error message saying 'Class file name must end with .class' (see stack trace below). This does not seem to be happening on all projects, just o...
I'm part of a team that develops a pretty big Swing Java Applet. Most of our code is legacy and there are tons of singleton references. We've bunched all of them to a single "application context" singleton. What we now need is to create some way to separate the shared context (shared across all applets currently showing) and non-shared c...
I'm working on an app that converts source code from using one framework to another. I really wanted to make the agonizing monotonous job automatic. After looking a lot for something that code help me treat source code in an object-oriented way and modify it the closest thing I've found was JaxMeJS and that's short of what I need too. I...
Hi, Recently I tried understanding the use of java.math.MathContext but failed to understand properly. Is it used for rounding in java.math.BigDecimal, if yes why does not it round the decimal digits but even mentissa part. From API docs, I came to know that it follows the standard specified in ANSI X3.274-1996 and ANSI X3.274-1996/AM ...
First of all, I know how to build a java application. But I was always puzzled where to put my classes. There are proponents for organizing the packages strictly domain oriented, others separate by tier. I for myself have always problems a) with naming, b) with placing Where do you put your domain specific constants (and what is the be...
Searching for some sample code for converting a point in WGS84 coordinate system to a map position in Google Maps (pixel position), also supporting zoom levels. If the codes is well commented, then it can also be in some other language. You can also point me to a open source Java project :) Some resources found: OpenLayer implementa...
What is the best way to verify/test that a text string is serialized to a byte array with a certain encoding? In my case, I want to verify that an XML structure is serialized to a byte array with the UTF-8 encoding which is of variable character length. As an example, my current ugly procedure is to inject a character known to require t...
I am writing an application in Java for the desktop using the Eclipse SWT library for GUI rendering. I think SWT helps Java get over the biggest hurdle for acceptance on the desktop: namely providing a Java application with a consistent, responsive interface that looks like that belonging to any other app on your desktop. However, I fe...
I have read through several reviews on Amazon and some books seem outdated. I am currently using MyEclipse 6.5 which is using Eclipse 3.3. I'm interested in hearing from people that have experience learning RCP and what reference material they used to get started. Thanks in advance. Bruce ...
At my work we are running a group of tests that consist of about 3,000 separate test cases. Previously we were running this entire test suite on one machine, which took about 24-72 hours to complete the entire test run. We now have created our own system for grouping and distributing the tests among about three separate machines and the ...
