Integrate signed applet in java web application

Question

I have a java applet project whichs starts a webcam and displays it on a window. I am trying to integrate this applet into my web-app, for that I have exported my applet as a JAR and included in my web-app and used it on my JSP page by using applet tag. Now I got a message that the digital signature cannot be verified. I am currently trying to sign my applet and use it, but I don't find any tutorials for that.

Can somebody please guide me that?

What I am trying to do is legal or can I try some other way to integrate my applet into JSP page or any other way to have webcam capture functionality in Java web application.

Answer 1

Emm... I do suppose so when you 'exported' your applet to JAR the signature became invalid or something; actually any modifications make it invalid... so I guess you need to

• A) As a tip, first clean your JRE certificates cache (then try to restart your JSP; if it won't do then read B,C points)
• B) Pack your (with blank manifest) applet into JAR
• C) If you have the keystore sign the applet JAR with jarsigner util

Report if that helped

You need to sign an applet jar before running it as an applet. This is a link for your reff.: http://docs.oracle.com/javase/tutorial/deployment/jar/signing.html Once jar is signed you can run it, if it still does not work try options for running signed content under: control Panel: Java
