我有一个在 Java 6 上使用 JSP 2.1、Servlets 2.5 和 JSTL 1.2 的 web 应用程序。我使用 maven-jetty-plugin 6.1.1rc1 进行测试，没有任何问题。从这个链接：http ://docs.codehaus.org/display/JETTY/JSP+2.0+v+JSP+2.1 ，我知道如果在 JDK 5+ 上，jetty 6 将选择 JSP 2.1，它工作正常。

这是我的 pom.xml 的应用程序战争的相关部分：

<!--servlet & javax-->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>2.5</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.1</version>
            <scope>provided</scope>
    </dependency>

现在我想使用 cargo 和 jetty6x 嵌入式设置自动化集成测试。容器启动良好，没有错误。但是，我无法呈现任何 JSP。这是我得到的例外，据我所知，这是因为使用了 JSP-2.0 impl 而不是 JSP-2.1。

(TagLibraryInfoImpl.java:547) - Unknown element (deferred-value) in attribute

和Caused by: java.lang.NoSuchMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext; at org.apache.taglibs.standard.tag.common.core.SetSupport.doEndTag(SetSupport.java:140)

这是我的货物配置：

<plugin>
<groupId>org.codehaus.cargo</groupId>
<artifactId>cargo-maven2-plugin</artifactId>
<version>1.0.1</version>
<configuration>
    <container>
        <containerId>jetty6x</containerId>
        <type>embedded</type>
    </container>
    <configuration>
        <deployables>
            <deployable>
                <groupId>groupId</groupId>
                <artifactId>artifact</artifactId>
                <type>war</type>
            </deployable>
        </deployables>
    </configuration>
    <wait>${cargo.wait}</wait>
</configuration>
<executions>
    <execution>
        <id>start-container</id>
        <phase>pre-integration-test</phase>
        <goals>
            <goal>start</goal>
        </goals>
    </execution>
    <execution>
        <id>stop-container</id>
        <phase>post-integration-test</phase>
        <goals>
            <goal>stop</goal>
        </goals>
    </execution>
</executions>

cargo jetty6x 容器也使用了jetty的v6.1.1rc1，所以肯定和cargo使用jetty的方式有关。我知道 cargo 对其容器依赖项的版本进行硬编码，而不是使用 maven 依赖机制（可能有充分的理由，jira ->CARGO-571）

所以我的问题是：还有其他人设法使用嵌入了货物和码头 6x 的 JSP 2.1 吗？有什么建议让它工作吗？

非常感谢任何帮助！

好的，设法弄清楚这一点。货物邮件列表中的这篇文章很有帮助： http: //old.nabble.com/Jetty6-version-with-maven-plugin-td16722550.html。它描述了如何使用 cargo 自定义容器的类路径，但如果采用这种方法，则需要手动指定所有依赖项。

我从货物源中发现这些是jetty6x容器默认使用的依赖项：

jetty6xDependencies.add(new Dependency("org.mortbay.jetty", "jsp-api-2.0", "6.1.1rc1"));
    jetty6xDependencies.add(new Dependency("org.mortbay.jetty", "servlet-api-2.5", "6.1.1rc1"));
    jetty6xDependencies.add(new Dependency("org.mortbay.jetty", "jetty", "6.1.1rc1"));
    jetty6xDependencies.add(new Dependency("org.mortbay.jetty", "jetty-util", "6.1.1rc1"));
    jetty6xDependencies.add(new Dependency("org.mortbay.jetty", "jetty-naming", "6.1.1rc1"));
    jetty6xDependencies.add(new Dependency("org.mortbay.jetty", "jetty-plus", "6.1.1rc1"));
    jetty6xDependencies.add(new Dependency("ant", "ant", "1.6.5"));
    jetty6xDependencies.add(new Dependency("commons-el", "commons-el", "1.0"));
    jetty6xDependencies.add(new Dependency("tomcat", "jasper-compiler", "5.5.15"));
    jetty6xDependencies.add(new Dependency("tomcat", "jasper-runtime", "5.5.15"));
    jetty6xDependencies.add(new Dependency("tomcat", "jasper-compiler-jdt","5.5.15"));
    jetty6xDependencies.add(new Dependency("javax.mail", "mail", "1.4"));
    jetty6xDependencies.add(new Dependency("javax.activation", "activation", "1.1"));
    jetty6xDependencies.add(new Dependency("geronimo-spec", "geronimo-spec-jta", "1.0.1B-rc4"));
    jetty6xDependencies.add(new Dependency("xerces", "xercesImpl","2.6.2"));
    jetty6xDependencies.add(new Dependency("xerces", "xmlParserAPIs","2.6.2"));
    jetty6xDependencies.add(new Dependency("commons-logging", "commons-logging","1.0.4"));
    jetty6xDependencies.add(new Dependency("log4j", "log4j", "1.2.14"));

有问题的是tomcat，因为它们使用JSP 2.0。所以在设置类路径时，你需要排除那些，并包括JSP-2.1，即

<dependencies>
<dependency>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jsp-2.1</artifactId>
    <version>6.1.1rc1</version>
</dependency>

<dependency>
    <groupId>org.eclipse.jdt</groupId>
    <artifactId>core</artifactId>
    <version>3.1.1</version>
</dependency>

所以这里是整个配置：

请注意，您需要指定所有依赖项两次 - 一次在插件中，一次作为项目依赖项。您可以从第一个片段中获取版本。
