To create a JAR file in the IDE, you must first create a JAR contents file. The JAR contents file stores information about your JAR file, which you can later modify and use to create a new JAR file.
To create a JAR contents file:
For a more detailed description of this panel, see The JAR Contents Property Editor.
The JAR Contents file appears as a node in the Explorer (with the icon). On the node's property sheet, you can set a file filter, the JAR file's compression level, and other attributes.
To create a JAR file from a JAR contents file:
The JAR file can not be created if any of its contents or sources that the contents are compiled from are not in mounted filesystems.
To view the contents of the JAR file as a filesystem:
A filesystem node for the JAR file with the icon
will appear in the Explorer.
If you later change the JAR contents file and rebuild the JAR, you need to unmount the JAR file and then remount it to display the current JAR file.
