如何将JSTL添加到Maven? [英] How to add JSTL to Maven?

问题描述

我正在使用Mojarra，PrimeFaces和Tomcat 6.x进行JSF 2.0项目.

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

我需要将c:forEach用于一些素面组件，例如p:tab的动态数量，但c:forEach却有问题. JSTL的所有其他标签都很好用.

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.

我遇到以下错误:

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

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

我使用以下xmlns:c="http://java.sun.com/jsp/jstl/core"，我尝试用xmlns:c="http://java.sun.com/jstl/core"替换，但第二个则无显示.

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.

这是lib的确切版本:

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>

我该如何解决?

如有需要，我可以提供更多具体信息.

I can give more specific information if needed.

我添加并尝试了不同的作用域(运行时和编译)，但没有任何变化:

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>

推荐答案

您必须在发行版中包括jstl库.这可能是由容器提供的，尽管不建议这样做.当前版本的Maven依赖关系(在撰写本文时)在这里:

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>

尽管如此，始终值得检查 Maven中央存储库以获取更新.

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