Most obvious method is using session. In your example it does not
look like you are submitting anything important, or any user
input, so, it does not seem that first jsp should submit
data to second. If that is the true, then you can use the
request object and, add attribute to it (request.setAttribute()), and
let the first jsp to forward (jsp:forward) request to second (chaining).

What keeps you from sending it the same way that you send "name" or "Test"?

I would suggest reading one or two articles about "SQL-Injection-attacks"
and how to prevent them (hint: PreparedStatement).
