Jar File Manager

The Jar File Manager is a basic program that allows users to create, extract and list Jar files, SunSofts format for compressing and storing Java files.

Jar File Manager

This is a basic program, but it does allow the user to create, extract and view the contents of Jar files.

Menu Bar Actions :

File :
Create New Jar - This option clears all existing Jar info, allowing you to start a fresh Jar file.
List an existing Jar - This option allows the user to open an existing Jar file, and view its contents, you can also amend this list, by adding or deleting files from the list, and then saving the new Jar details as described below.
Extract an existing Jar - This option will extract an existing jar, it currently gives no options as to which files to extract, or where they will be extracted to. If there is no directory info for the stored files, it will write them to the same directory where the Jar file is, if there is directory info for each file, it will write the file to the appropriate directory.
Save Jar As - This option will save all the current files which are in the Jar list. It will ask the user for a Jar filename to save the files into. If you have checked the Create a Jar for use in a classpath box, then the Jar file will save without any compression. If you checked Exclude manifest file for the entries, then the Jar file will be saved without a manifest document attached.
Change Working Directory - Change the working directory.
Close Jar File Manager - Close the window, and returns to JEditor.

Options :
Add a New File - This will allow the user to select a file to add to the Jar file list.
Add all Files of Type - This option will add all the files in the directory of the type you select from that directory.
Delete Selected Files - Removes all the hi-lighted files from the Jar file list.
Select All - Hi-lights all the files in the Jar file list.
De-Select All - makes all the files in the Jar file list unselected.

Basically the Jar File manager works in a similar fashion to the Project Manager in the way it lists, adds and deletes files. It is only a very basic Jar Manager, and does not yet have much flexibility, in the way it handles files. It does not remind the user that a list or file has been changed, and it will only save files when you select the Save As option from the Menu Bar, you have no control on extracting files, therefore if you are in doubt as to where files are going to be extracted to, I strongly recommend that you use the List an existing Jar option first.

This program could turn into a major project in itself, and I will only consider expanding it if I receive enough user requests.
