i am using applet code in jsp page in weblogic server so pl help me in my jsp page it is showing all components

now i want to read file and display in appplet without server it is working but with server how to work i am not getting any permission should be kept
13 years ago
i have set the access permission buy
keytool -genkey -keyalg rsa -alias feroz
after i made the certificate:

keytool -export -alias feroz -file yourcert.crt

after that i have created a bat file which contains

javac Backup.java
jar cvf Backup.jar Backup.class
jarsigner Backup.jar feroz


The batch-file compiles the applet, makes a jar-archive and signs the jar-file.

but when i am running my html file iam getting this exception.
