Help on converting to myfaces/tiles + JSF + EJB3 + Seam

gus888 Jul 6, 2006 11:30 PM

Hi everybody,

I am newbie on seam and want to convert my project of myfaces/tiles + JSF + EJB3 to Seam. I worked several days, but could not figure it out. If I keep the following codes in web.xml

<context-param>
 <param-name>javax.faces.CONFIG_FILES</param-name>
 <param-value>
 /WEB-INF/faces-config.xml
 </param-value>
 </context-param>

I always got the following exceptions:

if I removed javax.faces.CONFIG_FILES in web.xml, I got other exceptions:

Any help will be very appreciated. I also very appreciate it if someone can post your web.xml and faces-config.xml. Thanks in advance.

JSF automatically loads faces-config.xml so you shouldn't have a specific reference to it in web.xml. You only need to put other files to load in javax.faces.CONFIG_FILES. If you do include it it gets loaded twice and hence all sorts of bad stuff happens (e.g. two Seam Phase Listeners are loaded)

Right, you should definitely not use javax.faces.CONFIG_FILES to reference /WEB-INF/faces-config.xml.

I don't know what your other exceptions are about, I have never seen them before. Probably not related to Seam.

Petemuir and Gavin,

Thank you very much for your directions, I fixed my problem after removing javax.faces.CONFIG and recoding my web.xml.

I have one more question, did anyone ever combine faces/tiles with facelets? Or is it possible? Thank you.

Best regards,

GUS

facelets has ui:composition/ui:define which lets you do the stuff that tiles is mostly used for. I understand that tiles has some extra functionality but are you sure you need it?

Hi Gavin,
Yes, I used myfaces/tiles in my project, and it is great. Now, I also want to use facelets, but I don't know whether it is possible to keep the myfaces/tiles and also use facelets functions. Thank you.

So my suggestion is to try using the built-in tiles-like features of facelets.
