some HFS doubts till chapter 7

[shankar valiinaykam]

Dear All,

1. P-169. WEB-INF/classes is one of places where listener class can be placed. WHAT ARE THE OTHER PLACES?

2. P-205. ctx.getResourceAsStream("bookcode.jar"); Forward slash is missing. I guess this is a typo. Am I right, kathy?

3. P-206. Since HttpSessionBindingListener is implemented by Attribute class, I feel it should fall under Attribute listener rather than placing in life cycle listener. If I am wrong, pls explain?

4. P-213. Q-12- D,E says the attribute and API for getting query string from forwarded request. Can I use the same thing for request from client also?

5. What is the value for setMaxAge() of cookie, if I dont want it to be expired. In case of session, it is -1. Here, if I say, -1, cookie disappears as soon as browser shuts down. So, that makes me wonder what is the value for keeping COOKIE EVER?

6. Inside attributeReplaced API, event.getVale() returns old value. How do I get new value?

Waiting for your replies,
Thanks in advance,
Shankar

1. P-169. WEB-INF/lib is another place
2. P-205. I agree there is a forward slash missing

3. P-206. I agree but hope somebody else comment on it
4. P-213. Yes you can use them .
5. The api says "A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted." Your question still stays how to keep cookies alive for ever ?

6. Please answer if anybody have answer for this.


Regards,
Ranajit Jana

5: For ever is a really long time. A bit of an imposition. I don't think HTTP supports it as an expiration.
6:How about:

Object newRequestAtt = rEvt.getServletRequest().getAttribute(rEvt.getName());
//OR
Object newContextAtt = cEvt.getServletContext().getAttribute(cEvt.getName());
