Can not find the tag library descriptor of springframework

1. Download the Spring dependency jar
2. Place it to the lib folder path is /WEB-INF/lib/spring.jar

3. Then open the web.xml and the sample code is:

   <taglib>
     <taglib-uri>/WEB-INF/spring.tld</taglib-uri>
     <taglib-location>/WEB-INF/spring.tld</taglib-location>
   </taglib>
   

4. Then the taglib is indicated where the jar file locates in ur system.

   <%@ taglib prefix="spring" uri="/WEB-INF/spring.tld" %>
   

I know it's an old question, but the tag library http://www.springframework.org/tags is provided by spring-webmvc package. With Maven it can be added to the project with the following lines to be added in the pom.xml

<properties>
    <spring.version>3.0.6.RELEASE</spring.version>
</properties>

<dependencies>

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

Without Maven, just add that jar to your classpath. In any case it's not necessary to refer the tld file directly, it will be automatically found.
