why javax.servlet-api doesn't contain jstl?

Question

I read example describes cretation simple web mvc application. At this examples in pom.xml added only

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
            <version>3.1.0</version>
            <scope>provided</scope>
        </dependency>

but when I invoke this application I got same error:

java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config
    at org.springframework.web.servlet.support.JstlUtils.exposeLocalizationContext(JstlUtils.java:101)
    at org.springframework.web.servlet.view.JstlView.exposeHelpers(JstlView.java:135)

...

after adding

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>

problem is absence.

Is it normally that javax.servlet doesn't contain jstl or is it my error?

Or is it author's example error or maybe something another?

You don't have to use jstl when working with the servlet API. You can also write directly to the outputStream. For that reason it makes sense that these are separate artifacts.

Are there exist link between versions of jstl and servlet-api ? – gstackoverflow Mar 22 '14 at 11:25
See for instance http://stackoverflow.com/questions/2013879/the-ultimate-java-version-table-j2ee-java-ee-servlet-jsp-jstl – Robert Scholte Mar 22 '14 at 11:45
I don't see information about servlet 3 (only 2.5) there – gstackoverflow Mar 22 '14 at 14:21
Please read and follow the links on that page... or google for java ee versions – Robert Scholte Mar 22 '14 at 15:54
You really need to work on your search skills: http://en.wikipedia.org/wiki/Java_EE_version_history#Java_EE_6_.28December_10.2C_2009.29 – Robert Scholte Mar 22 '14 at 20:13
I saw this link bit I don't understand how I can to know answer using this page – gstackoverflow Mar 22 '14 at 21:14
Back to original question: you need to specify both, Spring can't specify for you which JSTL version you want to use, neither for the servlet specs. It means: if you expect your webapplication to run in a JEE6 webcontainer, your application can use Java Servlet (API) 3.0 and JSTL 1.2. – Robert Scholte Mar 22 '14 at 22:29
@ Robert Scholte but if I use only servlet container Tomcat – gstackoverflow Mar 23 '14 at 07:55
Look up the version of Tomcat, and see which JEE version it supports. http://tomcat.apache.org/whichversion.html – Robert Scholte Mar 23 '14 at 09:56
strange that I can work wih tomcat 7 and servlet api 3.1 – gstackoverflow Mar 23 '14 at 10:15
