I'm truly disappointed JSF support in eclipse. I'm encountering such caveats all the time.

I'm using JBoss 7.1.1 and even adding JBoss as the Target Runtime of the project didn't help.
The only solution that worked for me, was to define new JSF library inside Eclipse: Window Preferences -> Java -> Build Path -> User Libraries -> click New (pointing to the jsf-impl.jar and jsf-api.jar). And then adding such library to the build path of the project.

It solved all annoying eclipse errors can not find tag library. So it is pretty similar to the @Riccatti first solution.

Btw: answer which I found on the eclipse forum says that this error is usually caused by not existing JSF tag libraries (that are present in jsf-impl.jar) on the classpath.
