In JSP this absolute URI http://java.sun.com/jsp/jstl/core cannot be resolved ...... Solution

About org. Apache. Jasper. jasperexception in JSP:

This absolute URIHttp://java.sun.com/jsp/jstl/core) Cannot be resolved in either web. xml or the jar files deployed with this application

According to "proficient in JSP-web development technology and typical applications", I typed a piece of jstl code. I did not expect an error. It took me an afternoon to sit down and hurt my ass ......

My development environments are eclipse 3.2.0, myeclipse 5.0, Tomcat 5.0.28 (which uses jre1.4), and jdk1.5

I searched the internet for the same statement: the jstl version (1.0 and 1.1) is inconsistent. There is also check the virtual directory under the WEB-INF directory lib folder (if there is a lib folder, then create a dynamic) whether there is jstl. jar and standard. jar two jar packages. If not, copy them to Lib.

All tried, but the error is still ...... Later, I found my own mess. After the above change, there are two solutions:

The first is to import jstl1.1 in Eclipse project, download the jstl1.1 http://jakarta.apache.org/taglibs/index.html
Then decompress and put *. jar and *. TLD under the/WEB-INF/lib directory. That isIn all the jakarta-taglibs-standard-current.zip (jstl class libraries. jar and. TLB put in the Lib folder under the WEB-INF directory, JSP File Import <% @ taglib prefix = "C" uri = "/WEB-INF/lib/C. TLD "%>,The test is acceptable.

The second is to modify web. xml and add the following statement:

<JSP-config>

<Taglib>

<Taglib-Uri> http://java.sun.com/jsp/jstl/core </taglib-Uri>

<Taglib-location>/WEB-INF/C. TLD </taglib-location>

</Taglib>

<Taglib>

<Taglib-Uri> http://java.sun.com/jsp/jstl/xml </taglib-Uri>

<Taglib-location>/WEB-INF/X. TLD </taglib-location>

</Taglib>

<Taglib>

<Taglib-Uri> http://java.sun.com/jsp/jstl/fmt </taglib-Uri>

<Taglib-location>/WEB-INF/FMT. TLD </taglib-location>

</Taglib>

<Taglib>

<Taglib-Uri> http://java.sun.com/jsp/jstl/ SQL </taglib-Uri>

<Taglib-location>/WEB-INF/SQL. TLD </taglib-location>

</Taglib>

</JSP-config>

Import in JSP<% @ Taglib prefix = "C" uri ="Http://java.sun.com/jsp/jstl/core"%>.It should be okay ......

The second type is recommended. ^_^!
