Unable to read TLD “META-INF/html_basic.tld”

while starting my Tomcat it showed

javax.servlet.ServletException: org.apache.jasper.JasperException: /index.jsp(1,1)
Unable to read TLD "META-INF/html_basic.tld" from JAR file
"file:/E:/workspace/eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/cams/WEB-INF/lib/jsf-tlds.jar":
org.apache.jasper.JasperException: Failed to load or instantiate TagLibraryValidator class: com.sun.faces.taglib.html_basic.HtmlBasicValidator

It turned out that I was including a copy of  jsf-tlds.jar in my WEB-INF/lib directory, but my tomcat already had one.

So, I deleted the jar file from my WEB-INF/lib. It works now 🙂
