I’m new to Maven. I recently learned it to solve some dependency issues I’m having with a Java and Spring WebApp. I’ve been trying maven out on a small sample webapp. The webapp uses JSTL tags. I found it necessary to put these tags in pom.xml:

   <dependency>
        <groupId>javax.servlet.jsp.jstl</groupId>
        <artifactId>jstl-api</artifactId>
        <version>1.2-rev-1</version>
    </dependency>

    <dependency>
        <groupId>org.glassfish.web</groupId>
        <artifactId>jstl-impl</artifactId>
        <version>1.2</version>
    </dependency>

These get 2 jars that I need:

jstl-api-1.2-rev-1.jar
jstl-impl-1.2.jar

BUT it also includes THIS jar in my WEB-INF/lib, the inclusion of which causes all sorts of errors when I try to run it in Tomcat 7:

jsp-api-2.1.jar

Is there a way I can rewrite my dependency tags to leave jsp-api-2.1.jar out of my WEB-INF/lib ?

Thanks

Fixed. Thanks Guys. FWIW, this is how I changed the dependency tags for the JSTL to not put the JSP-API jar in my WEB-INF lib:

   <dependency>
        <groupId>javax.servlet.jsp.jstl</groupId>
        <artifactId>jstl-api</artifactId>
        <version>1.2-rev-1</version>
        <exclusions>
            <exclusion>
                <groupId>javax.servlet.jsp</groupId>
                <artifactId>jsp-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.glassfish.web</groupId>
        <artifactId>jstl-impl</artifactId>
        <version>1.2</version>
        <exclusions>
            <exclusion>
                <groupId>javax.servlet.jsp</groupId>
                <artifactId>jsp-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

I was able to find the groupID and artifactID at this site

    Have exclusions section, similar to the one below.

    <dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate</artifactId>
  <version>3.2.6.ga</version>
  <exclusions>
    <exclusion>
      <groupId>javax.transaction</groupId>
      <artifactId>jta</artifactId>
    </exclusion>
  </exclusions>
</dependency>

    In your case, one (or both) of the dependencies you add include the one that you do not need. Find which one, and add the exclusion section.
