And when I open the reply sent for my questions(on opening the link which I got as part of notification in my email id) I get this message:

Oooops. You don't have sufficient privileges to access this message

Please help me to get out of this...

Thanks

I am not sure about the error you saw, but the thread was trashed because someone wanted to look at the content of the post. I hope you know why.
Here is the OK bit:
I am planning to give SCJP1.5 before Mar2010. I am also doing a Diploma course in Java. I got my SCJP voucher from some other institute,threfore my teacher doesnot help me with SCJP1.5.
I have very limited and the basic knowledge of SCJP1.5. I found that Cathay Sierra is a good book to refer. But I found that SCJP1.5 version of Cathay Sierra is no longer available in market because SCJP1.6 version replaced it. Now i want to know can I refer SCJP1.6 book for giving SCJP1.5 exam.

We don't allow conversations on some of the other bits as they violate some of the site policies.

Well, the topic has been moderated (trashed) -- but your user account is fine (not banned or anything).
