Hi all, I am new to facelets. My first try is failed because of java.lang.ClassNotFoundException: org.apache.commons.logging.impl.Log4JLogger. I am sure I did not have this exception when I did not use facelets. I am useing tomcat 5 and all the log4j jars are included in my project. I dont know where to troubleshoot.
Have you seen this error when you use facelets? Can anyone kindly provide a simple example for facelets? Thanks a lot!
