Hi!

1. You can supply your JavaBeans without source code, just classes. They do not contain source code (though they can be decompiled).

2. You can use Servlets instead of JSP-pages. They are classes too thus no need to worry about the source code.

3. Your JSP code is only visible for server side. It means that none of the clients will see it. But server needs to see the code to be able to interpret it.

4. Use jspc utility if you want to compile your JSP to Servlet. It's available in Tomcat.

Regards!

If I understand your qustion correctly ->

your JSP and javabeans are always there on the server and can never been seen by the clint in the browser, all he can see is only HTML

Hope this helps
Cheers!

dear all, like what you've said, they can always decomplie back from the .class file. In fact i did that all the time when i need to change the contain of the .war file if i have to.
Don't think this is the ideal way...

Applekanna, correct. It's in the server, that's why i need to protect from accessing by any local peoples. This is beacasue i am going to deliver a project to one of my client and i afraid he will abuse my code by resell it to another party......

Thank You.

as vk33 said: don't install JavaBean sources - only classes
and what about:    .jsp - just compile them, and the same, don't install sources :)

to avoid decompilation use obfuscator
