Re: Need Suggestions

Hello Mike,

I am not sure I understand your problem exactly, but I would suggest getting
familiar with the javax.servlet.http.HttpSession interface.  Using its
putValue and getValue methods you can "store" objects in one servlet and
"retrieve" them in another servlet.  I am not sure that HttpSession is the
solution to your problem, but any application using multiple servlets will
probably need to implement an HttpSession object.

You could also share data between HTML windows with different techniques in
javascript.  However, I would highly recommend the use of server-side java
over javascript in any case when either would apply, especially when moving
data from one page to the next.

Are you using JSPs?  If not, I would suggest moving in that direction.  It
is a powerful, yet easy to learn technology.

Thanks,
Dave Duerr
