Standard way of adding JSLT 1.2.1 in a Maven Project? - maven

Question

What is the standard pom for adding the 1.2.1 JSTL taglib in a maven project. Any recommendations as to when/if can this be scoped as provided ? Any server peculiarities (interested in Jboss 7, Glassfish 4 and/or Tomcat 7)
EDIT: Added:
<dependency>
<groupId>org.glassfish.web</groupId>
<artifactId>javax.servlet.jsp.jstl</artifactId>
<version>1.2.1</version>
<scope>provided</scope>
</dependency>
This adds:
Notice it transitively adds the 1.2 api.
I am using provided as I am using Jboss which should provide it: Basic question complicated solution - Tomcat to JBoss. Still this is the 1.2 api apparently
$ find . -name *jstl*.jar
./modules/javax/servlet/jstl/api/main/jboss-jstl-api_1.2_spec-1.0.2.Final.jar
(contains implementation also). So would the correct way be to add the jstl jars to the pom (not in provided scope) and mark the servlet-api (I'm on 3 anyway) as provided somehow ?

Answer 1

Ended up using :
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
<!-- Add the jstl-api dependency explicitly - otherwise jstl-api 1.2 is added -->
<dependency>
<groupId>javax.servlet.jsp.jstl</groupId>
<artifactId>javax.servlet.jsp.jstl-api</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>org.glassfish.web</groupId>
<artifactId>javax.servlet.jsp.jstl</artifactId>
<version>1.2.1</version>
<exclusions>
<!-- jstl-api was adding selvlet-api 2.5 and jsp-api-->
<exclusion>
<artifactId>jstl-api</artifactId>
<groupId>javax.servlet.jsp.jstl</groupId>
</exclusion>
</exclusions>
</dependency>
Not sure if I should add the jstl-api dependency - please comment (I would accept a more authoritative answer actually). Result:
