问题 I am trying to create a Java applet with JInternalFrames. For this I believe you need a JFrame in one form or another. I heard you could wrap your applet in a JFrame, is that best? If you could tell me what I should do I would appreciate it. TYIA -Roland /** * @(#)rebuiltgui.java * * rebuiltgui Applet application * * @author * @version 1.00 2013/1/21 */ import javax.swing.JInternalFrame; import javax.swing.JDesktopPane; import javax.swing.plaf.basic.BasicInternalFrameUI; import java.awt.event

问题 I have wrote my first java applet. It basically loads some images from my Django webserver and then the user can modify them. I developed it in Eclipse, and I had no problems at all. When I tried it with a test page, on the java console come out this error: java.security.AccessControlException: access denied (java.net.SocketPermission www.hyros.net resolve) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:374) at java.security.AccessController.checkPermission

问题 I'm working on Flex application and I need to open a Java Applet from Flex (e.g. clicking a button). In particular I'd like to open imageJ, a particular imaging program that could work as application, applet or be integrated in a web page. Is there a way to call it from Flex? I've seen a couple of tutorials that explain how to call a single function in another Java file from Flex, but I'm not so sure that it is what I'm looking for. Thanks for your answers, cheers, David 回答1: I don't know if

问题 I was following this tutorial here and I downloaded its source code and ran but the image is not showing. here is the result I was expecting that the result would be like this same as the result in the tutorial. Here is the code: StartingClass.java package kiloboltgame; import java.applet.Applet; import java.awt.Color; import java.awt.Frame; import java.awt.Graphics; import java.awt.Image; import java.awt.event.KeyEvent; import java.awt.event.KeyListener; import java.net.URL; public class
