creating a jar file

[po0oker]

hi

i would like to create an executable jar file that runs by double clicking ..

could someone please explain it step by step


thank you in advance

If your .jar contains a class with a main and the main point is set to that class (IDEs do this automatically, or at least Netbeans does), it should run automatically on doubleclick. Sun's Java Tutorials have all the info you need.

thx for your help .. yeah i did create one but for some reason i keep getting this error and i couldn't find an answer to it anywhere ...

the error is
""could not find the main class . program exit "

you have to have the files.... like if you made it through netbeands IDE you'd have files so make sure the files are at the same location as the jar

which files ?? i placed everything in the same directory

ok maybe the problem is because my main class is linked with other classes .. could this be the reason of getting the error ?

if the jar tool is already been set in the classpath....

Follow the pattern....

jar -cmf manifest.mf NameOfYourJarfi le.jar *.class

If the jar tool have not been set on classpath...
Put all your class in the bin folder....

Do it in CMD in Win, or terminal in linux....

-cmf can be found on jar help....

Manifest tutorials are on the web..... ;-)

Hi,
I would like to add one more point to sukatoa ,
You have to write Manifest.txt file in that you have mention like
"Main-Class: yourPackage.you rClassName"
Then you follow the below procedure..
--> jar cfm JarName.jar Manifest.txt yourPackage/*.class
--> java -jar JarName.jar

Hope it helps you.:-)
