Dynamic Web Project with JSF v1.2 & tomcat 6.0.28 [message #548621]

Hello,

I've created an Eclpise Dynamic Web Project with JSF v1.2 as Project Facets
configuration. I've also added jstl-api-1.2.jar, jstl-impl-1.2.jar and standard.jar libraries to
my WEB-INF/lib project to avoid having some classNotFoundException problems.

But when I deploy my project on tomcat 6.0.28 my jsf page is not available. I have the 404 error.

I'm using Eclipse 3.5
Thanks

I have two suggestions.

- Try a working tutorial such as the one I review at

http://www.javahotchocolate.com/tutorials/wtp-jsf.html

- Look through my rather disorganized notes demonstrating problems I had
myself doing this and how I overcame them:

I hope this helps,

Excellent tutorial and companion notes. I've managed to finish my first app in few minutes. BUT I have the problem refernced as "Millions of console nastygrams launching JSP " in the Companion notes. I removed one of the two mappings
</servlet>




<servlet-mapping>
<servlet-name>faces</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>

But I still have the same problem:
SEVERE: Servlet.service() for servlet faces threw exception
java.lang.StackOverflowError

I think web.xml should contain (among other things, see
http://www.javahotchocolate.com/tutorials/jsf-notes.html#web .xml):
..
..
..
<servlet-mapping>
<servlet-name>faces</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-mapping>
<servlet-name>faces</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>.

I found the problem but I don't really understand how it works.

In my generated (from eclipse WTP) web.xml I have 2 different definitions of Faces Servlet:

<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class >
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>

...
<servlet>
<servlet-name>faces</servlet-name>
<servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class >
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>faces</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>

So when I try to access to my jsp pages using http://localhost:8080/de.vogella.jsf.first/faces/Convertor.j sf I have problems (a non ending stack trace) but this using the same url without the "/faces": http://localhost:8080/de.vogella.jsf.first/Convertor.jsf it works.

What I 've understand from these 2 servlet definitions: depending on the url, MyFacesServlet or FacesServlet or both will be started. Is it correct ?
And my problem come from the urls that maps the 2 definitions like this one: http://localhost:8080/de.vogella.jsf.first/faces/Convertor.j sf

I have to confess that I haven't spent that much time trying to
understand the black art of web.xml. Once I have a working one, I copy
it to future projects that do similar things and tweak it for that
project. I don't compose it from scratch.

There are brighter colors than I in the box of crayons that is the
Eclipse WTP forum. Perhaps one of them will answer you.

I solved the problem by removing one of the two FacesServlet definition. In fact, if the url matches the two FacesServlet mappings in the same time (e.g. .../faces.blah.jsf) I have this "Millions of console nastygrams launching JSP" problem.

Thanks

If you wouldn't mind, please send me both? That way, I can draw some
useful conclusion and add this to my jumble of notes (that will one day
be the foundation of a tutorial).

(Both web.xml files, that is.)
