What Can Cause a NullPointerException in java.awt.Graphics.setClip Under Microsoft VM?

There's a ten-year-old Java applet I've recently been asked to fix some bugs in, and one of those only occurs when running under Microsoft's old JVM rather than Sun's. (Or, at least, it doesn't occur under any recent Sun JRE - I haven't dug out Sun Java 1.1 to try and check.) Yes, I'm aware that Microsoft's JVM is end-of-life, and I've...

<applet height="100%"> causes vertical scrollbar in IE. Why/how to avoid?

Why does this create a veritcal scrollbar in IE6, IE7 and IE8? How to avoid it? (I had a real applet in there, but I discovered that this heavily mutilated one gave the same result and helps simplify the test case) <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt; <html> <head...

Soundbank for Java

I am working on a Java applet that uses javax.sound.midi.sequencer to play a MIDI sequence. In order for this to work, the visitor needs to have a soundbank installed on his/her computer. Apparently, the Windows JRE doesn't come with a soundbank, and one has to be downloaded separately from http://java.sun.com/products/java-media/sound/...

Radio items in GNOME panel applet's context menu

Is there a way to put radio menu items in a GNOME panel applet's context menu, and then control which of the items is marked as active? The official documentation is less than helpful, and all of the applets installed on my computer use normal menu items, so I can't look at their source code for any guidance. ...

Understanding Java applets

Hi, I am trying to understand how applets work. I understand that a class file is bytecode, something that a JVM can understand and execute. When an applet runs on the user's system, the bytecode is transferred to the user system over the network. Now, what happens when there are more than one class files? For example, what if the cl...

Is it possible to install a custom class loader for java applets in the browser?

I'll first admit that Java class loaders are a bit of a mystery to me. What I'd like to do is define a class loader that would load any applets the browser encounters. I know I can modify the policy file to grant elevated privileges and install a custom loader inside of an applet. What I'd like to do is change the default class loader...
