Question

I’m working on a JSF 2.0 project using Mojarra, PrimeFaces and Tomcat 6.x.

I need to use c:forEach for some primefaces component like dynamic number of p:tab but i have problem with the c:forEach. All the other tag of JSTL work nice.

I have the following error :

java.lang.NoClassDefFoundError:
javax/servlet/jsp/jstl/core/LoopTagStatus

I use the following xmlns:c="http://java.sun.com/jsp/jstl/core", i tried to replace with xmlns:c="http://java.sun.com/jstl/core" but nothing display with the second.

This is the exact version of lib:

<dependency>
    <groupId>javax.faces</groupId>
    <artifactId>jsf-api</artifactId>
    <version>2.0.2-FCS</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>com.sun.faces</groupId>
    <artifactId>jsf-impl</artifactId>
    <version>2.0.4-b03</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.primefaces</groupId>
    <artifactId>primefaces</artifactId>
    <version>2.2.1</version>
</dependency>

<dependency>
    <groupId>javax.el</groupId>
    <artifactId>el-api</artifactId>
    <version>2.2</version>
</dependency>

<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>el-impl</artifactId>
    <version>2.2</version>
</dependency>

How i can fix it ?

I can give more specific information if needed.

EDIT:
I added and tried different scopes (runtime and compile) but nothing change:

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

Answer 1

You must include the jstl library in your distribution. This may be provided by the container, although that is not recommended practice. The maven dependency for the current version (as of writing) is here:

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

Although, it’s always worth checking the maven central repository for updates.
