Hi,
can someone tell me how to effectively reuse jsp code?
I have seen three techniques:
i) put the code into a bean - needs more access to the web server than I have
ii) call another jsp - screen flickers
iii) cut and paste - the usual problems
Is there another way that I have missed?
Yours
Declare your getConn( ) method inside the declaration tag i.e.
%!
.your code here
%
instead of the scriptlet tag.
This could be one reason for the error.
Have a nice day.

Before asking questions of a general nature, please check out the
resources available online to see if your question already has an
answer. The best place to start
If you use a link you can just write:
A HREF="bbb.jsp?useris=value"...
If you use a form, you could use a hidden field

How can I get user informations from jsp

E.g. if I use OAS with SSL
