JSF – Richfaces (java.lang.NoClassDefFoundError)
I was getting an error like this even though I had my commons-collections.jar in the class path
java.lang.NoClassDefFoundError: org/apache/commons/collections/map/AbstractHashedMap
Solution: I had to download the new version of the jar file to make it work commons-collections-3.2.jar from apache commons.

About
I am the Obi-Wan, the master of jedi. I am also a Software Engineer in Oklahoma City. My expertise is in Java EE, object-oriented application development, and use of open source frameworks. I primarily work on the design and development phases of Java EE applications. I have been with my current job for about six years and I have a degree in computer science.
In this blog I will be posting issues about JSF, Facelets, Ajax, Spring, JPA, Portal, Web Services, GlassFish App Server and anything Java EE related technologies those I use to deliver contents over the browser. I will be concentrating my difficult moments during development phases and how I tackle those issues to perform my daily job. Click here to read NASE Glassfish application server success story.
