Richfaces 4.0.0.Final is out there, and so far it’s pretty useful as usual, but when I wanted to add it in my NetBeans project on JSF 2.1.2, many exceptions, many unrecognizable stack traces.
I started googling, after hundreds of results and surfing I ended up with collecting what I needed to get it working, and to my surprise I needed three extra jars.


Come on JBoss how come you didn’t mention that, this version’s documentation is still soooo poor, neither the documentation, nor the showcase demo are to any help.
Anyway, here are the three needed jars, download them:
guava-r09.jar
sac-1.3.jar
cssparser-0.9.5.jar

After you get them, your working Richfaces 4.0.0 library should have the next 7 jars:
richfaces-components-api-4.0.0.Final.jar
richfaces-components-ui-4.0.0.Final.jar
richfaces-core-api-4.0.0.Final.jar
richfaces-core-impl-4.0.0.Final.jar
guava-r09.jar
sac-1.3.jar
cssparser-0.9.5.jar
