No taglib could be found with this URI
===

Error message:

**Failed to compile JSP /EN/MYSITE/someDeal.jsp   
No tag library could be found with this URI. Possible causes could be that the URI is incorrect prefx=html in this line:**

    <%@ taglib uri="http://www.mysite.com/myproduct/tags/htmltag-10" prefix="html"%>

But i made sure i have all the correct jstl.jar and standard.jar in the WEB-INF/lib folders. Where else am i missing? i am thinking of checking the web.xml but i dont know what to look for exactly.

Also, i didnt deprecate any taglib URI in the last build. I recently migrated to Weblogic 12 and started using the new Oracle Pack Eclipse too.
Thanks
