I have a JavaServer Faces (JSF) Application and I been trying to run it through Tomcat 6.0 with Eclipse Europa IDEbut I keep getting an error message in JAVA that says, “java.lang.NoClassDefFoundError: javax/faces/event/SystemEventListener”. I also have JSF-API 2.0 and jsf-impl.jar. What should I do to resolve this?

No Class Def Found Error on JSF


That is a possible problem with the JDBC connectivity, you may have configured the settings wrongly and that is why you are getting that problem. You will therefore need to check that issue in the JavaServer Faces application and resolve it for the application to work properly.

You will need to follow the procedure below to resolve that problem:

  • First you will need to open the JavaServer Faces application.
  • Once it is opened you will need to go to Tools in the application's main menu.
  • And then you will choose the 'Run Application' tool.
  • Try executing it and see if you will find the 'java.lang.NoClassDefFoundError'
