IDE never displays... Do you see any error messages when you run it from the console? People have reported various problems getting the Linux version to run.

The above quotes came from messages in that group. IBM is supposed to have released 3.5 for Linux by now with Java 2 support, but I haven't seen it. I have been pestering their Business Partners and seminar presenters at every opportunity asking when it will be released; I suggest that other Linux users anxious to use the product do the same. -- === Glenn Holmer ([EMAIL PROTECTED]) --- Don't say that you have no choice With no one to hear your voice You can shout and make no sound Or whisper up a storm --- -Robin Trower, 1994 === -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Odd reflection issue
I'm not sure what is going on with what I'm doing, so thought I'd ask for
some help. My environment is Sun JDK 1.3.
I am trying to understand reflection. When I run the command 'java
com.bascom.TestClass3' from a terminal, I get this output (I'm only
pasteing in the pertanent part):
[treaves@double treaves]$ java com.bascom.TestClass3
4
Fields for TestClass3
=
Field 0: private int com.bascom.TestClass3.attribute3
Field 1: private java.util.HashMap com.bascom.TestClass3.hasmMapAttribute
Field 2: private java.lang.String com.bascom.TestClass3.lastAttribute
Field 3: private static java.lang.Class
com.bascom.TestClass3.class$Ljava$lang$Object
This is what I get from BeanShell:
bsh % Class testClass = Class.forName("com.bascom.TestClass3");
bsh % Field[] fields = testClass.getDeclaredFields();
bsh % print(fields.length);
3
bsh % print(fields);
Array: [Ljava.lang.reflect.Field;@6f247 {
private int com.bascom.TestClass3.attribute3
private java.util.HashMap com.bascom.TestClass3.hasmMapAttribute
private java.lang.String com.bascom.TestClass3.lastAttribute
}
So when I run from the commandline, it lists that there are four fields,
and in BeanShell it lists three. The command line shows the
java.lang.Class as the fourth field. Why? What am I missing?
Thanks.

/dev/random with SecureRandom?
Most Linux kernels include the /dev/random device - anyone using it to seed an implementation of the JDK's SecureRandom facility? The default initialization algorithm used by the JCE is pretty darn expensive when we have a pretty good source of bits at hand. Is it possible that blackdown already does this?

JTable mouse click
When I double-click on a JTable, the MouseEvent event is saying the getClickedCount ==1. It always equals one regardless of the actual click count. I'm using JDK 1.3 from Sun. Any advice? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
