Quoting "Cooremans, Rony" <[EMAIL PROTECTED]>:
> I ll try the web.xml solution as soon as i solve some other bugs
Take a look at this:
I have a Servlet called XMLServlet:
<servlet>
<servlet-name>XMLServlet</servlet-name>
<servlet-class>XMLServlet</servlet-class>
</servlet>
And I map everything with extension html, pdf, xml, rtf to this Servlet:
<servlet-mapping>
<servlet-name>XMLServlet</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>XMLServlet</servlet-name>
<url-pattern>*.pdf</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>XMLServlet</servlet-name>
<url-pattern>*.xml</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>XMLServlet</servlet-name>
<url-pattern>*.rtf</url-pattern>
</servlet-mapping>
In the servlet I replace the extension by xml and I go looking
for the file somewhere on my filesystem (could be a parameter
in the web.xml too to do it really nice). Depending on the
extension, I construct a PDF, HTML, RTF or XML file...
It's magical, isn't it???
This is what they call MVC:
1 Model, 1 Controller, multiple views!
Or didn't you see the movie 'Lord of the iText'?
One document to rule them all,
One servlet to find them,
One library to bring them all
and in the Brightness bind them ;-)
