Jdev 10.1.2 problem define jstl tagLib

Question

hi,
i have a problem in my jsp when i compile it with JDev 10.1.2, when trying to use JSTL tag:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I always get the following message:
Error(3,49): Attribute 'xmlns' used but not declared.
Error(4,58): Attribute 'xmlns:xsi' used but not declared.
Error(5,105): Attribute 'xsi:schemaLocation' used but not declared.
Error(6,18): Attribute 'version' used but not declared.
Error(33,19): Invalid element 'context-param' in content of 'web-app', expected elements '[resource-ref, security-constraint, login-config, security-role, env-entry, ejb-ref, ejb-local-ref]'.
Error(34,18): Invalid element 'description' in content of 'context-param', expected elements '[param-name]'.
but i saw this tutorial http://www.oracle.com/technology/products/jdev/tips/schalk/taglibs/taglibs.html
and i check my preferences about my projet, i had the libraries standart.jar and jstl.jar to my project (Project Properties->Profile->developement->Libraries), and they are located in my <project>/public_html/WEB-INF/lib/
And for the declaration of the taglib,
Tools->Manage Libraries-> JSP TagLibraries the prefix "c" is defined, and it is the same uri what i'm using in my jsp.
I make another with jdev 10.1.3, and i put my project, i compile and it work very fine.
Thanks for any help.
Regis.
