I just want to know whether is there any way to give a security to the webpages hosted in server. For example, I have hosted jsp application using tomcat. I want to prevent someone from copying those files from tomcat in my computer(Maybe from C Drive). Anyhelp will be appreciated.

I am not familiar with Tomcat, but how would they copy the files off? Make sure that you do not allow "directory browsing"- not sure what that would be called in Tomcat.

Do you have any other services running that could expose the file system?
