            To vaildate a form simple override a default vailidate() method from ActionSupport class


Code

public void validate() {
        if (getUname().length() == 0) {
            addFieldError("uname", "User Name is required");
        } 
        if (getPass().length() == 0) {
            addFieldError("pass", "password is required");
        }
        else if (!(getUname().equals("candidjava") & getPass().equals("1234"))) {
        	 this.addActionError("Invalid User Name or Password");
        }
