Are these perhaps old programs dating back to the early days of
Swing? Swing's package names changed a few times - if this is old
code, it may be looking for the wrong classes.

Hi,
I started to work with servlets and found that I need to download
Servlet API classes - servlet-2_2b.zip package. I have few questions
about this package.
1. Does it run on Linux?
2. Where jdk directory structure I have to place it in:
a) /jdk/jre/lib/ext
b) should I create /jdk/jre
You need to do 'xhost +' on the X server machine, or xhost +machinename.

Either you have a wrong CLASSPATH (are you using JDK1.1 ?) or your normal
PATH isn`t correct.
Perhaps you should try something like this (if you have JDK1.2)
With C-Shells: setenv JAVA_HOME /my/jdk/path (e.g /usr/local/jdk1.2)
With Sh-Shells: export JAVA_HOME ...

Making classes static has good sense if they are nested. Usually nested

hidden constructor parameters. But static nested class is just like a

You can pass the name of a class ("com.foo.package.Name") as a
parameter, and then so long as the class can be found either locally
on the client, or via the ARCHIVE=___.jar tag, you can create an
instance via something like:

try this:
public Object makeInstance(String sClassName)
{
Class rC
Yes. If your class has a no-arg constructor, just do like this:
void method(Class c)
{
...
Object o = c.newInstance();
... // use 'o'
}
Otherwise, look for a Constructor class documenation from
java.lang.reflect package to create and initialize your object
