Running JSF examples from SUN

Find no way to get the SUN's examples of JSF working. Tried on SUN's app server,

on tomcat 5.0, on tomcat 5.5, on special (!) tomcat5.0-jwsdp from sun

nothing work as explained on various java-sites.

last try : install latest Java EE 5 SDK., got latest J EE tutorial and:

From the JEE tutorial :

cd javaeetutorial5/examples/web/guessNumber/

ant

BUILD FAILED

Buildfile: build.xmlexamples/bp-project/main.xml:20: Class org.apache.tools.ant.taskdefs.ConditionTask doesn't support the "else" attribute.

any idea ?

PS: myfaces examples worked out-of-the-box on tomcat 5.5 !!
