java.lang.NoClassDefFoundError: org/ajax4jsf/resource/InternetResourceBuilder

My application, which uses JSF 2 and Richfaces 3.3.3, and mojarra 2.0.2 works fine on Glassfish 3.1 , but whenever i port it on Tomcat 7.0.10, every time i get one or the other problem. It started with failure to detect jsf_core.tld , followed by some JSF rendering issue and finally this one. Lastly i found some which i m mentioning here and which i cannot find a way around to fix.

You've the RichFaces impl JAR file, but not the RichFaces API JAR in the runtime classpath.

The stacktrace is evidence of this:

Caused by: java.lang.NoClassDefFoundError: org/ajax4jsf/resource/InternetResourceBuilder
    at org.ajax4jsf.renderkit.ChameleonRenderKitFactory.<init>(ChameleonRenderKitFactory.java:62)

The at org.ajax4jsf.renderkit.ChameleonRenderKitFactory line indicates that this particular class was successfully loaded and executed (otherwise it wouldn't have shown up as an at xxx in the stacktrace at all). This class is part of RichFaces impl JAR file. The InternetResourceBuilder is in turn part of the RichFaces API JAR file. This is apparently missing in the runtime classpath. At least, that's just exactly what the exception is telling us.

From the exception it seems that Richfaces cannot be found. Put the jar in your classpath (for Tomcat WEB-INF/lib or WEB-INF/classes) and try again.
