Get Started

Hi everybody, I am chaitanya, I want to implement j_security_check in my web application. Previously I used sessions to provide security for my web application. Now I want to migrate to j_security_check. Can anybody please tell me how I can do this. Where can I get enough matter to do this.

I searched the web here and there the whole day. At last I coded these pieces which are not working. I don’t know whether these are right or wrong. Please can any one tell me what mistake I have done and where can I study online.

Q: How is this related to the OP’s question?
A: It’s not, start your own thread next time.

The answer to your question of how to manipulate the DOM with Java is simple: you don’t.
Java is a server based language, DOM manipulation occurs on the client side - stick to Javascript.
