Subject RE: query parameters
Date Mon, 09 Dec 2002 15:06:12 GMT
Well, i understand what you are suggesting.  Let me re-state my question in
a different way.  How can i set it up so that when a user goes to, it would automatically
load the form and display results from the database pertaining to record
with ID=5 (obviously the next and prev links would have the appropriate
query parameters).

I know (i think) how to do this directly in the JSP (using JSTL's
db-querying tags), but i thought that only the servlet should access the
database and obtain the record, so how would my JSP page invoke the servlet
to get the data from the database?  Am i over-complicating it? :(
