JSP throws an exception org.apache.jasper.JasperException__Js

Deploying Project Web in Eclipse sometimes accessing a JSP throws the following similar exception information
Org.apache.jasper.JasperException:The Absolute uri:http://java.sun.com/jsp
Deploy the Web project if this exception is thrown. Please ensure that the Standard.jar and Jstl.jar two jar packages exist in the deployed project, if they do not exist, please
The two packages are added to the/web-inf/lib. Then ensure that the version address referenced in the JSP is consistent with this version address:

<%@ taglib uri= "Http://java.sun.com/jsp/jstl/core" prefix= "C"%> <%@ taglib uri=
"http://java.sun.com/" Jsp/jstl/fmt "prefix=" F "%>

Jsp. 1.1 After the path with JSP 1.0 is not. The version corresponds. The problem is solved.
