How do I execute .jar files?

[GBscientist]

I unzipped a folder containing a complete java program with all the supporting files. When I click the .jar file that should run the program, it just opens in Ark. How do I execute this .jar?

I installed Sun Java, but I haven't configured it as my primary Java VM yet. Would this make a difference? If so, step-by-step instructions on how to configure Sun Java as my Java VM would be appreciated.

The standard command to execute the someapp.jar program would be
java -jar someapp.jar. That assumes java is configured correctly and in your PATH. To configure the Sun JVM look here

And how would I make sure that Java is correctly added to my PATH? What is a PATH?

Re: How do I execute .jar files?

the PATH environment variable is a list of directories. When you type an executable command, these are the directories that your system searches for to find that command. If you install something (like java) to a directory that isn't in your PATH the system won't find it. Don't get hung up on that for now, install Java according to the instructions and issue the java -jar command. If everything works then no problem. If there is a problem we can sort it out at that point.

Is there any way of turn it an automatic process when i click the file?

I mean I dont want to run the command on konsole, just click on it and it opens.

I don't know how you would add a file association to the jar to make it run the command in the java -jar configuration, but you can create a one line shell script (text file with .sh extension) which contains the command:

"java -jar myapp.jar"

Place it in the same dir as myapp.jar, make it executable (right click -> properties -> permissions tab: check box for "is executable" and click ok) and it should "just work" when you click on it (not the jar).

Good suggestion, but i want a general solution for all jar files.
Following what you said, it is necessary to create one script for each jar file and this is not practical =/
