在Maven Eclipse项目中找不到Spring框架的标签库描述符

Question

The following three lines at the top of documents.jsp throw "cannot find tag library descriptor for ..." errors in the spring framework application from this tutorial , which uses eclipse and maven:

<%@ taglib uri="http://www.springframework.org/tags"  prefix="spring"%>  
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>  
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>  

My understanding is that the maven plugin for eclipse should manage the download of these libraries automatically, so I checked to make sure that the following are included in pom.xml:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-webmvc</artifactId>
  <version>${org.springframework.version}</version>
</dependency>

<properties>
  <org.springframework.version>3.0.2.RELEASE</org.springframework.version>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>  

So how do I fix my application to enable the required dependencies to be available? I want to avoid having to do it manually, because I was under the impression that maven should manage this. Is there some way that I need to manipulate maven? The application apparently worked when it was tested for the tutorial.

EDIT:

I converted my eclipse project to a maven project and then right clicked on the eclipse project and chose Maven>Update Project. This did nothing to fix the error that still remains from my original posting above, but it also added the following new error:

Missing artifact javax.transaction:jta:jar:1.0.1B  

Which is now thrown by the second line of pom.xml, which reads as follows:

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

SECOND EDIT:

When I try to run as..run on server, I get the following error in a dialog box:

'Publishing to Tomcat v7.0 Server at localhost...' has encountered a problem.

Error reading file D:\mypath\.m2\repository\javax\transaction\jta\1.0.1B\jta-1.0.1B.jar
D:\mypath\.m2\repository\javax\transaction\jta\1.0.1B\jta-1.0.1B.jar (The system cannot find the file specified)  

I even set "update Maven projects on startup" in Window>preferences>Maven and then closed and restarted eclipse, but the problem persists.

Answer 1

I passed for this same issue where I receive the message

"cannot find tag library descriptor for ..."

I solved putting spring-webmvc inside of my war. This error happened when spring-webmvc were in server folder.

I suggest you see how do you're packaging your war.
