How to deal with Warning: This page calls for XML namespace primefaces.org/ui declared with prefix p but no taglibrary exists for that namespace.

Yesterday I did a example using PRISMFACE, JSF2, and I got below error:

Warning: This page calls for XML namespace primefaces.org/ui declared with prefix p but no taglibrary exists for that namespace.

After I copied primeface jar into lib directory, everything is working. So wired.

I think this might be a Maven issue.
