I am doing some Struts work after a long time. Interestingly it is for a Test Driven Development training. A client wants me to do a hands on session, using Struts 1.x, and EJB's. They also want to do the hands on sessions with a small but production project. It seems their developers are tired of Calculator and Shape projects :-) Well I can't really blame them. I have been planning to create some micro applications around diycomputerscience.com . I hope to create each application using a different technology, so I can have several reference points for teaching. For this session I am going to make a web application which will store and display my slides. I am sure you are thinking ... but why not just use SlideShare ? Well besides the fact that I think this makes a great application that is small, but also production quality. Ideal for using to teach. But there are other reasons as well. It is very hard to embed code snippets on Slideshare. Slideshare also does not support co...

Today I was writing a unit test which instantiated a class, which started a thread to do some stuff. I was hoping to test the side effect of that thread. However, to my surprise, I realized that Eclipse would forcibly terminate the test after the test method exited, even before the thread completed it's work. I wrote a simple test to show this. import com.sun.org.apache.xpath.internal.operations.And; import junit.framework.TestCase; import junit.textui.TestRunner; /** * This class shows that Eclipse's JUnit test case runner will forcibly terminate * the JVM and all running threads */ public class ThreadTest extends TestCase { static Runnable run = new Runnable() { public void run() { int cnt = 0; while(true) System.out.println(cnt++); } }; public void testThread() { Thread t = new Thread(run); t.start(); } public static void main(String args[]) { TestRunner runner = new TestRunner(); runner.run(ThreadTest.class); } } This cl...
