how to protect my source code which is in webapps from to copy or see others.Please help me

First why is the java source code in webapps directory?
If you are worried about jsp code, then jsp code can never be accessed through browser it get compiled and executed into html and be served to browser.
If you think that some will hack you webapps/yourApp directory and get access to it, then you can try placing your jsp pages in your applications WEB-INF directory which is very difficult to get access to. You can probably create a seperate directory like "jsp" and place all your jsps in it.

I'm not sure I understand you correctly but If I do I think you are asking about a technique known as 'code obfuscation'. One of the better ones I've come across is by YGurad. See www.yworks.com here. As for protecting your JSPs and Servlets ie: making it inaccessible from 3rd party access , you could place it in the WEB-INF or META-INF directories. Note: your Java source code is not going to be exposed to the outside world regardless. As a side note web app security(for the purpose of constraining certain resources) should be inherently built into your app using things like authentication and authorizations. There are of course also other advanced ways but since this a beginner's forum I wont get into that .You can configure alot of this in the DDs as for most of the time, the security constraints should be done declaratively.
