sounds like a problem with the el-api.jar

check through all your libraries and be sure you dont have duplicate el-api.jars.

EL is now part of the JEE container, but on older J2EE containers that wasn't true. For example, Tomcat5 doesn't have it, but Tomcat 6 does. When you build a WAR, you have to make sure that you know whether the server you're using does or doesn't have EL support built in. It's just as bad to NOT include an el implementation jar in a WAR targeting Tomcat 5 as it is to include one in the WAR for an app running under Tomcat 6, because you'll get mix-and-match issues between the two conflicting WARs and classpaths.

I don't know exactly when JBoss acquired EL support, but the same problem applies there.

"privilege" comes from the Latin words for "private" and "law" (legal) and dates to feudal times. To "claim privilege" meant that you were above the laws that applied to the common people.

also check the 'faces-config.xml' file, and the validity of managed beans, maybe you using a managed bean that not registered in 'faces-config.xml' yet
