I have a WTP setup that has been working well for most of this year. I
am using 3.1 and the update site code.
I decided to take a look at facelets, and downloaded it and put the jars
(for Facelets and Sun JSF) in a user library in my WTP project. I am
fairly familiar with JSF from a previous project.
I get a fairly fundamental error when I try to start up my Tomcat 5.5.16
server with a project that has the JSF jars defined:
org.apache.catalina.core.StandardContext listenerStart
SEVERE: Error configuring application listener of class
com.sun.faces.config.ConfigureListener
java.lang.UnsupportedClassVersionError:
com/sun/faces/config/ConfigureListener (Unsupported major.minor version
49.0)
at java.lang.ClassLoader.defineClass0(Native Method)
...
I have seen this error before and I know it's a Java compile level
problem. Trouble is I can't see how to resolve it. I got it when I
only had 1.4.2 installed, so I installed 1.5.6 and redefined my runtime.
but still get the problem. I'm fairly sure that neither Facelets nor
JSF are involved in this problem, even though it's a JSF class that is
failing. I'm missing something simple...
