If the jar is on the class path and you use proper imports, your current class can access the classes held by the jar file.

it doesn't effect.
How about the jar file is located in spesific folder.
PS: i attach my file that will made as external jar that will be called

Here is my case:
1. i've made a desktop application using netbeans
2. it contains main.class that launch the myForm.class.
3. it works when run from its project and netbeans
4. then, i made it became a jar file
5. i put the jar file in a specific folder (eg. as same folder as the new desktop app. 'll load the jar). so, how i should load it when run time (using source code)
