Hi Torsten! > Is it technically possible to merge an existing application which use > Servlet+JSP and JSF together. > Yes, it is. This is what we did with our application too. We also wrapped the old pages in an JSF view so that we have a FacesContext available for the whole application. Even the Header/Footer includes are in JSF now, only the "content" is still JSP for the old pages. This is where the f:verbatim tag comes in handy :-)

Well, and then the fact that JSF pages aren't easily bookmarkable might also be a problem if you have to provide your user something like a navigation history (breadcrumbs). > The only thing i don't know, if the session and application scope data > can be "merged" - but it should be possible, should it? > These scopes are already "merged" the session scope in JSF is the same as with JSP/Servlet. Prepare for a lot of work, and the fact that you never ever would like to edit your "old" JSP pages once you eaten the JSF drug ;-) Ciao, Mario
