Hi, Rohit
A servlet is not created every time you click on a link referencing one. There
is only one instance of the servlet class associated with every registered
servlet name (unless your servlet implements the SingleThreadModel interface, in
which case the servlet container may pre-create a pool of instances). A servlet
has access to its initialization parameters by calling
GenericServlet.getInitParameter(String name) for each named parameter. The
initialization parameters thus obtained are set on server startup in your web
application's web.xml deployment descriptor, which means they don't vary at
runtime.
I'm just guessing at what you're trying to do, but it seems you want to perform
a query on the second HTML page based on a selection criterion from a parameter
passed in the first. In this case, if the parameter does not vary, you can
embed something like this in your first page:
<a href="/myapp/myservlet?param=myparam">
If your parameter varies, then you probably have to set up a form to receive the
parameter before sending it.
I realize that the above explanation might seem rather concise for someone new
to servlets. I can help you best by directing you to Sun's Tutorial on Servlets
Hope this helps.
Regards,
Noel Lecaros
