I wonder what happens when my browser goes to a web-page like this. When I try to google for "browser" and "applet" mostly it finds how to add applet to browser and troubleshooting, but not how it works.
<html>
<head><title>My Applet</title></head>
<body>
<applet code="org/mypackage/MainClass.class" archive="MyApplet.jar,libA.jar,libB.jar" width="1600" height="860"></applet>
</body>
</html>
If the web-page is remote then I guess browser has to download all mentioned jars in archive
parameter to some temporary folder and then browser asks Java Plugin to process next. So the plugin would find then jar which has MainClass
and would start Java program execution.
Is my understanding correct?
My applet requires many external jars, so I have packages only my classes into MyApplet.jar
. Then in a separate folder I put
MyApplet.jar
libA.jar
libB.jar
applet.hmtl
And double click applet.html
In manifest for MyApplet.jar there is
Rsrc-Class-Path: ./ libA.jar libB.jar
Class-Path: .
Is it really necessary to put these line in manifest?

Basically, barring an applet deployed using Java Web Start and lazily downloading the library Jars either depending on need, or programmatically.

If the Jars are as follows they do not need to be referenced in the manifest.
archive
attribute of the applet
element.resources
section of the JNLP as a jar
element.
