While connecting with JMS through an Applet, the following error is taking place. But when we connected through JAVA application its working fine. The code is attached.

I have written a sign certificate for the program and registered.
But still it generates the same exception.
This is what I used to sign the applet
--------------------------------------
jar cvf SignedApplet.jar *.class
keytool -genkey -alias signFiles -keystore susanstore -keypass kpi135 -dname "cn=jones" -storepass ab987c
jarsigner -keystore susanstore -storepass ab987c -keypass kpi135 -signedjar Smapplet.jar SignedApplet.jar signFiles
keytool -export -keystore susanstore -storepass ab987c -alias signFiles -file SusanJones.cer
Thanx in advance.
