Installing Java Software

[dnr01]

Can anyone help me with installing java software from sourcecode. I see a lot of nice programs I would like to download but I pass them by because I can't seem to get the hang of Java installs. I have installed the latest version of Java from their websit so shouldn't I have everything I need to do an install.

Thanks

If you let us know how exactly you setup java, which apps you tried to install and where exactly you experienced difficulties, we maybe able to help.

I've been trying to install a program (one of many java based programs) called SnortKonsole and when I run a java <filename> I get this

[root@localhost SnortKonsole-0.1]# java SnortKonsole-0.1.jar
Exception in thread "main" java.lang.NoClassDefFoundError: SnortKonsole-0/1/jar
Caused by: java.lang.ClassNotFoundException: SnortKonsole-0.1.jar

[root@localhost SnortKonsole-0.1]#

By the way, I am running Mandriva 2008.1

Thanks

Also this is all I know about what I have installed for java.

[root@localhost SnortKonsole-0.1]# java -version
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-b24)
OpenJDK Client VM (build 1.7.0-b24, mixed mode)

That doesn't mean much to me but I hope it helps you guys.

Thanks

if i'm not mistaken i think you run a java app with the command java -jar app-name.jar

Thanks, that worked to get the program running. Now I know.
