(long tweet) This page calls for XML namespace declared with prefix body but no taglibrary exists for that namespace.
Case
On creating a new JSF 2 page, I get the following warning when the page is displayed:
Warning: This page calls for XML namespace declared with prefix body but no taglibrary exists for that namespace.
Fix
In the XHTML page, replace the HTML 4 headers:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>...</html>
with XHTML headers:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"> ...</html>
