java.lang.ClassNotFoundException: com.sun.el.ExpressionFactoryImpl

When running JSF with Tomcat 7.0, I stumbled upon this error. Turns out, you  have to put the following JARS in Tomcat's library folder before running your project.

My Path: C:\Program Files\apache-tomcat-7.0.23\apache-tomcat-7.0.23\lib
Note: This may vary from different users
  • el-api-2.2.jar
  • el-impl-2.2.jar
