hello how are yall.?
i have a simple question..
i'm currently doing a standalone java project using Eclipse IDE..
how can my users open the application without opening Eclipse and run from there?

sorry im a newbie

in your command line first compile by javac then execute by interpreter java

in windows use javac.exe and java.exe

for a standalone application you can deploy it in a jar file and its properties allow you to execute from the class which has a main() method and which you set as Main-Class
else you can use a batch file that has instructions to run your program from the command line shell just as you do without an IDE

Not really need to jar anything
On the console window cd to where your .class files are and then
> java MyClass

"Not really need to jar anything"

True. But if you have multiple classes, and especially if there are required non-standard libraries, it's much easier to make the jar your deployable unit so you don't have to screw around with classpaths and whatnot.

yup i got a lot of classes in the application..furthermore, if i want to give this to client, wouldnt it be hard for them to always run it from cmd or terminal?

Are you building this in an IDE, or from the command line?

Most IDEs will have an annoying pointy-clicky way of making an executable jar. Of course, annoying pointy-clicky is apparently a feature in IDEs, so maybe you'll like it. In Eclipse, it's under "Export", in the file menu, if I remember correctly. It'll walk you though a set of clicks, and then you'll have an executable jar.

Or, if you're coding for real, you'll have set up a build file which will have a "jarfile" target - executing that will whip up a jar for you, and you don't even have to exit vi to do it.

Not that I'm biased about development environments or anything...

Just choose Export in Eclipse and it will jar the application. Run as

java -jar exported-jar.jar
