SEVERE: JSF1005: Cannot instantiate validator of type javax.faces.Bean
I search on the net but couldn't find any solution.
How is this caused and how can I solve it?
回答1:
Your webapp's runtime classpath is dirty.
This is a pretty generic problem which can not have a single suitable answer without having a complete overview of all libraries supplied in the webapp deploy. My best guess would be that you've placed RichFaces source code JAR files in /WEB-INF/lib. RichFaces ships with separate JAR files for the binary classes and for the source code. You should not put RichFaces source code JAR files (the ones with a filename ending on -source) in the classpath. Remove them and keep the binary JAR files. The source code JAR files contain in turn also several startup scripts. They should not be executed twice.
As to the CSS problem, this is likely unrelated. RichFaces loads CSS through the new JSF2 <h:head> component. Make sure that you have in your (master) template(s) a <h:head> instead of <head>.
