I'm new to event-driven programming, so I need some help with resources to get me started. To be specific, I'm currently making a program where it creates a game board, and I need help in creating code to detect when a piece is moved to a space on a board. -- I am only a mirage.

I've always been bothered about having to statically declare the size of a Java applet window (container?) in the calling HTML. I've always wanted the moral equivalent of width=50% statement (of the window or frame). I can sort of get an example working in a Mozilla browser: > <!-- This works on Mozilla only (and maybe netscape) --> >...

I have no background in encryption, so I'm working with samples I've found in various places and patching them together. I know Blowfish can use a 56 byte key. The version of this program in Perl has no problem with a 56 byte key, but this Java version has problems if I use a key that is any length other than 8 bytes. Is there something I...

I've searched over and over again and have not been able to find a definitive answer. Basically, we have a heavily JavaScripted web site. What I was hoping to do was to start enhancing our site by calling some Java functions via JavaScript. I have tried every sample I could find on the net and none of them works with Mozilla or Explorer....

Hi, I have some old code that uses the deprecated copy command as : ByteArrayOutputStream bout = new ByteArrayOutputStream(); StringReader sr = new StringReader(strString); copy(sr,bout); how could I achieve the same result without the now redundant copy command? Thanks

In Weblogic 7.x, I can define a bean using the Struts bean:define tag and then access the bean's methods in a script.

Hi, I'm Chris Thiessen. My partner and I need your help. We're finishing up what we think is a great compliment to the core Java API's, but we need feedback from other developers. We'd really appreciate it if you could spare 5-10 minutes to fill out a survey and help us shape our creation to your needs. Those who do so before November 1...

I have the following method inside I class, public boolean equals(Object o) { return (this.equals(o)); } but when i call this method by "foo.equals(bum)" where foo and bum are some objects, I get a java.lang.StackOverflowError??

Example String testString = "Testing \t tabs"; JOptionPane.showMessageDialog(null, testString, "TEST", JOptionPane.INFORMATION_MESSAGE); Instead of getting the output "Testing tabs", I get something more like "Testing | tabs" (although it isn't a pipe symbol, it's something unusual).

Hi, I have the problem switching off the "loading of external DTD" feature while transforming xml/xslt with XALAN. The used xml-parser is XERCES.
