I have one web application where i am using applet.The following exception is thrown in console & applet is not loading.

Dealing with ClassLoaders is one of the things applets are forbidden to do in their security sandbox. See HowCanAnAppletReadFilesOnTheLocalFileSystem on how to get around that.

Hi
I have taken care all these aspects and it is working fine also.But why only sometimes it fails?
