JAR files

[Lingerz]

Can someone explain to me in detail how I would pack my files into a JAR file? I've searched around as well as checked out tutorials yet I'm still clueless. :rolleyes:

Help would be appreciated. :)

I'm not sure what kind of answer you expect here. Understand that you're not asking a specific question, but rather are asking about a general subject, how "in detail" to create Jar files. This subject when discussed in the tutorials takes several pages to describe. I'm not sure how you expect us to answer this better than the tutorials or your textbook or how are we expected to know just what it is you don't understand, much less how we are going to have the time to write essentially a book chapter seeing as how we are all volunteers with jobs/lives/families...

My suggestion is that you go through the Sun tutorials again but this time taking notes. Then after going through them, review your notes and come on back with any specific questions or misunderstandings that you have.

You may also want to read this link as I know that it has helped me and others here to ask questions that are more easily answered: How To Ask Questions The Smart Way

Best of luck!

I need help with the command.

At the moment I have:

jar cvf Chat.jar *

In a command file. This causes the above (jar cvf Chat.jar *) to be echoed repeatedly. I'd like to ask, what am I doing wrong?

Start with
Lesson: Packaging Programs in JAR Files
and work with the section
Using JAR Files: The Basics
with special attention to the creating, viewing and running sections.
Then work with this page
Working with Manifest Files: The Basics
and especially this
Setting an Application's Entry Point
It takes patience and practice to work through these tutorial pages.

I just made a folder named "jarTest" and copied a source file "A" and its class files into it.
Navigating to the folder and then executing:

jar cvf AJar.jar *

I got a jar file "AJar" appearing inside the folder and the following output:

C:\jexp\jarTest>jar cvf AJar.jar *
added manifest
adding: A$1.class(in = 1637) (out= 954)(deflated 41%)
adding: A$2.class(in = 678) (out= 446)(deflated 34%)
adding: A$3.class(in = 977) (out= 637)(deflated 34%)
adding: A.class(in = 7665) (out= 4071)(deflated 46%)
adding: A.java(in = 14478) (out= 4217)(deflated 70%)

Exactly how did you execute it? I'm a bit lost. :s

[hardwired]

how did you execute it
I typed this at the prompt

C:\jexp\jarTest>jar cvf AJar.jar *

and pressed the enter key.
This makes a jar file including all files inside the "jarTest" folder.

Note from the path in the prompt that the current directory is the "jarTest" folder.
I navigated to that folder with the "cd" command at the prompt

C:\jexp>cd jarTest

and pressing enter, resulting in

C:\jexp\jarTest>

That worked, thanks alot. :)

@OP You mentioned that you had the command in a command file of some sort. If you had named that file "jar dot some executable extension" then the OS may have got confused and kept on calling the command file rather than the actual jar executable. That would explain the continual display of the command on the screen.
