your code base written wrong. should relative web path.

in case should testweb/applet-classes. put applet classes there, not under web-inf. web-inf place should store classes run on server side. folder may not accessible web. applet classes downloaded jvm running browser, web-inf may not visible it.

better way pack applet classes jar file , put under root of application. in case code base codebase='myapplet.jar'
