As you’ve already discovered, a computer may very well have several network interfaces with different IP addresses and it’s a little bit difficult to guess which one you consider to be “correct”, as they are all actually correct. My crystal ball suggest me that you mean the IP address, which the client is using to … Read more
Aside from the obvious use of the Java console and the applet viewer, starting from Java 6 update 7, you can use the VisualVM that comes with the JDK (JDK_HOME/bin/visualvm). It allows you to view the stack traces of each thread and even view all object instances. AppletViewer is very handy, you can do a … Read more

Implement an AppletStub & set it as the stub of the applet instance. E.G. /* <applet code=”ParamApplet” width=”200″ height=”200″> <param name=”param” value=”foo”> </applet> */ import java.applet.*; import javax.swing.*; import java.net.URL; import java.util.HashMap; public class ParamApplet extends JApplet { public void init() { String param = getParameter(“param”); System.out.println(“parameter: ” + param); add(new JLabel(param)); } public static … Read more
Here’s a simple example of rotating text. Addendum: You’ll want to adjust the the text’s radial starting point by stringWidth(name[n]). Your program appears to be rotating individual characters in a effort to follow the arc, while the example appears to be drawing the text in a straight line tangent to the arc. The latter approach … Read more
You don’t need the slash at the start when getting a resource from a ClassLoader, because there’s no idea of a “relative” part to start with. You only need it when you’re getting a resource from a Class where relative paths go from the class’s package level. In addition, you don’t want Test.class.getClass() as that … Read more
Sure, just extract the two jar files and recreate a new one $ mkdir tmp $ (cd tmp; unzip -uo ../jar1.jar) $ (cd tmp; unzip -uo ../jar2.jar) $ jar -cvf combined.jar -C tmp . The stuff with tmp ensures that the two existing jars are extracted into a clean directory and then the new one … Read more
My findings are the same: This prevents warnings with Java 7u21 – 7u40: Manifest-Version: 1.0 Trusted-Library: true This exclusivly prevents warnings with Java 7u45: Manifest-Version: 1.0 Application-Library-Allowable-Codebase: * Caller-Allowable-Codebase: * Mixing both won’t work in 7u45. Now what? Did anyone find a way to allow SIGNED applets with “all-permissions” to run without warnings in both … Read more
Making applets work across a wide range of browsers is surprisingly hard. The tags weren’t properly standardized in the early days, so Internet Explorer and Mozilla went separate directions. Sun developed a generic JavaScript to handle all the specific browser quirks, so that you don’t have to worry about browser compatibility. Add this to your … Read more
I finally found a edge detection system I like… Basically, the magic happens here… // Detect if we collided with any one (collision is the rectangle, bounds is us) if (collision.intersects(bounds)) { // Determine the intersect of the collision… insect = collision.intersection(bounds); // Flags… boolean vertical = false; boolean horizontal = false; boolean isLeft = … Read more
