Getting error on Simple JSF app

Hi All,

I have a simple page using JSF. I deployed it in Weblogic 10.3. When it's going to display the home page I get following exception:

Can you please help me on this?

Hi Mohamed,

Hi Hany,
Sorry for being late.
Here is the versions:

JBoss Seam 2.2.0.GA
jsf-impl-1.1_02
jsf-facelet-1.1.14
el-api-1.0

and jsf-1.2 is installed by Weblogic 10.3

Thanks Hany,

I changed the version of jsf-impl to 1.2_08 and it works now.

Thanks
