404 Not found when trying to redirect to another servlet

Question

I have the following code in a httpservlet:
String formURL =
"/servlet/coreservlets.OrderPage";
// Pass URLs that reference own site through encodeURL.
formURL = response.encodeURL(formURL);
out.println
("<FORM ACTION=\"" + formURL + "\">\n" +
"<INPUT TYPE=\"HIDDEN\" NAME=\"itemID\" " +
" VALUE=\"" + item.getItemID() + "\">\n" +
"<H2>" + item.getShortDescription() +
" ($" + item.getCost() + ")</H2>\n" +
item.getLongDescription() + "\n" +
"<P>\n<CENTER>\n" +
"<INPUT TYPE=\"SUBMIT\" " +
"VALUE=\"Add to Shopping Cart\">\n" +
"</CENTER>\n<P>\n</FORM>");
When I try to run this in jdev, it can't find the servlet referenced - coreservlet.OrderPage and I get a 404. I added servlet mappings of various flavors to the web.xml to no avail. Here are some examples of things I have tried in the web.xml:
<servlet>
<servlet-name>OrderPage</servlet-name>
<servlet-class>coreservlets.OrderPage</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>OrderPage</servlet-name>
<url-pattern>/OrderPage</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>OrderPage</servlet-name>
<url-pattern>/servlet/OrderPage</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>coreservlets.OrderPage</servlet-name>
<url-pattern>/servlet/coreservlets.OrderPage</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>OrderPage</servlet-name>
<url-pattern>/coreservlets.OrderPage</url-pattern>
</servlet-mapping>
Any thoughts?

I think the problem is with the dot, because dot means an extension.
Where is your OrderPage servlet..?
<url-pattern>/servlet/coreservlets.OrderPage</url-pattern>
From this statement I think it is in the folder coreservlets which is insdie the directory servlet. If that is the case then
Instead of a dot in "/servlet/coreservlets.OrderPage"
try giving "/servlet/coreservlets/OrderPage"
Hope this helps.
