How to start Java-Programs

[atrost]

I have a Java-Programm working in Windows with the JRE (Java Runtime Environment).
Is there in Kubuntu Java integrated or must i install Java manually - and when how?

Hello,
You can use Synaptic/adept.. to see what is installed or what is available to install (search java). I have installed it for my on because I want the latest version of Java from Sun, but I noticed that there was a lot of java software installed by default (compiler...).

In the other hand, if you are using Sun's jre, to start a java program try java name or java -jar name (be sure to have java in your path). Other's java implemetations may change.

Bye.

also, to hotswap between Java versions 1.4 and 1.5 (if you happen to have both installed) the command is:

sudo update-alternatives --config java

then press the number for which app should provide java and hit enter to save and quit.

Question about running Java programs:

When I run a Java program from Konqueror, the new window that launches doesn't have a window border. But when I run the same program from Firefox, it has a border. Is there a setting I must configure to make the window have a border?

I installed now some java-programs or part of java via Adept but i get errors starting my Java-Program. In other Unix- and Linux-derivates there is no problem starting my program.
Is there anyone who knows something about these errors (wikifon is the name)?
