(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>
Useful DTD
DTDs are useful when your XML editor take them in account: detecting errors, suggestions, complete statements… For instance, I save much time with IntelliJ IDEA automatic completion ; unlike, Eclipse amazingly does not implement this feature.
Here is a list of some widely used DTDs:
| File | DTD |
|---|---|
weblogic-application.xml |
<!DOCTYPE weblogic-application PUBLIC "-//BEA Systems, Inc.//DTD WebLogic Application 7.0.0//EN" "http://www.oracle.com/technology/weblogic/weblogic-application/1.1/weblogic-application.xsd"> |
weblogic-application.xml |
<!DOCTYPE weblogic-application PUBLIC "-//BEA Systems, Inc.//DTD WebLogic Application 7.0.0//EN" "http://www.oracle.com/technology/weblogic/weblogic-application/1.1/weblogic-application.xsd"> |
web.xml |
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > |
*.hbm.xml |
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> |
GWT modules |
<!DOCTYPE module SYSTEM "http://google-web-toolkit.googlecode.com/svn/trunk/distro-source/core/src/gwt-module.dtd"> |
GWT UI |
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent"> |
Tangosol / Oracle Coherence |
<!DOCTYPE coherence SYSTEM "coherence.dtd"> |
Log4J |
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> |
Tangosol and Log4J DTDs are included within their distribution JARs: you have to extract them or to give their path to IntelliJ IDEA.
