Thread: Need help on jar file creation and usage

Hi,

I have a project in eclipse and i want to create a jar file of the project so that anyone can use it without having access to the code. So i created the executable jar file of the project. Now can anyone please tell me how to use the jar file in another project? I have imported the jar file as an external jar file but what to do after that??

What is the purpose of this jar file? Are there methods in the jar that you need somewhere else? Is the jar a part of a larger project?

Also, this thread should be in java theory as this is not specifically an IDE issue.

Hi aesguitar,

Thanks for your reply. I want to include the jar as an external library in my current project and call the functions present in the jar file. As i am new to java i can't make out how to do that.

Sorry for any wrong usage of thread, being new to this community i might have missed that.

You import the parts of it you need with import statements, just as you do to use core Java libraries. If you've followed standard package naming conventions, your import statements would look something like:

import com.ritoban.ClassName;

If you need more help using packages and/or importing external jar files in Java, I recommend you refer to the corresponding Oracle tutorials.
