Hi,
I'm making a web-based wizard to create xsl templates. These templates are stored in a
database.
I have a servlet to control this wizard. It recieves a parameter, called "state" and
depending on its value, it decides which way to follow.
When it recieves state="1" and there is no template stored in the database, it stores
the new one and then it does this:
RequestDispatcher rd = req.getRequestDispatcher("iowa?event=TEMPLATES&state=2");
rd.forward(req, resp);
It DOES work.
However, when it recieves state="1" and there is already a template in the database,
it dispatchs the request to a jsp page. This jsp provides a button labeled "new
template". When it's clicked, my Wizard servlet is recalled with state="100".
In this state, the servlet removes the template from the database and does:
RequestDispatcher rd = req.getRequestDispatcher("iowa?event=TEMPLATES&state=1");
rd.forward(req, resp);
i.e. it returns to state="1".
This DOESN'T work. The getRequestDispatcher() method returns "null".
Does anybody know what could be happened?
Thanks a lot
