Any ideas ?

Answer : HI. I'M WORKING WITH TOMCAT AND JDEVELOPER AND I GOT

You didn't give the full error message. Hint: the
important part is all after the 'Root cause' line.
My first guess would be that you forgot to deploy the
jar containing the oracle.jbo.html.jsp.datatags.Utils
class. This need to go into WEB-INF/lib of your webapp or
under $CATALINA_HOME/lib.
