Servlet-Applet communication

Servlet-Applet communication

I have an applet successfully signed and deployed in my application.
I have a index.html which loads the applet correctly if I make a call like
/myApp
However,if I try to forward to index.html from a servlet, I´m getting a
ClassNotFoundException.
Here are the code that loads the applet.All these jars are in the
WebContent folder.
index.html
<applet code="com.griaule.grFingerSample.FormMain"
archive="fingerAssinado.jar,SignedGrFingerJavaAppletSampleAssinado.jar,postgresql-8.4-701.jdbc4Assinado.jar"
What am I doing wrong?
