JAVAWeb报错：The absolute uri: [http://java.sun.com/jstl/core] cannot be resolved in eith

今天学习JSTL，导入了jstl.jar和standard.jar包，点击运行，

报错

The absolute uri: [http://java.sun.com/jstl/core] cannot be resolved in

有人解释道：

Remove the standard.jar. It's apparently of old JSTL 1.0 version when the TLD URIs were without the /jsp path. With JSTL 1.2 as available here you don't need a standard.jar at all. Just the jstl-1.2.jar in /WEB-INF/lib is sufficient.

(移除standard.jar包，在JSTL1.0中需要，但是在jstl-1.2.jar中已经包含了standard,jar包，所以不需要在导入。)

也有人更改pom,xml如下：

I solved the same problem. I've just added JSTL-1.2.jar to /apache-tomcat-x.x.x/lib and set scope to provided in maven pom.xml:

(这个问题，我解决过，我仅新增JSTL-1.4.jar   复制道 /apache-tomcat-x.x.x/lib 并且设置scope提供在maven pom.xml)

 <dependency>
     <groupId>jstl</groupId>
     <artifactId>jstl</artifactId>
     <version>1.2</version>
     <scope>provided</scope>
 </dependency>
