How should i edit manifest for jar?

Question

I create an application - Instant Messenger - with connecting to MySQL and it required MySQL Driver, so I enclose this external library and this program works well. But I'd like to re-create this app as Applet and archive it to .jar How could I edit manifest for enclosing the Driver to Applet?

I know I can use (for desktop app) Class-Path: external.jar but does it work for applets either?

Thanks for all.

EDIT: Or is there another way how to enclose external jar to an Applet? E.g. with HTML code?

Solution 1

An easier way to edit a manifest file inside a JAR file is as follows:

• change the extension of your JAR file to ZIP, e.g. test.jar just rename it to test.zip
• unzip your file
• edit your manifest file using a text editor, e.g. notepad++
• zip the contents of the unzipped folder
• rename it to test.jar

Solution 2

If you're using the command line, then just typing jar prints this:

Example 2 allows you to specify the file that will be used as the manifest.
