如何使用JSP 2.1与Cargo maven插件和Jetty6x嵌入？

Question

我有一个在Java 6上使用JSP 2.1，Servlets 2.5和JSTL 1.2的webapp。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，据我所知，如果在JDK 5+上，jetty 6将选择JSP 2.1，该工作正常。

这里是我的应用战争的pom.xml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> 

现在我想建立使用货jetty6x嵌入式自动化集成测试。容器启动正常，没有错误。但是，我无法呈现任何JSP。这是我得到的异常，据我所知，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> 

的货物集装箱jetty6x也使用码头的v6.1.1rc1，所以它必须是事做与货物使用码头的方式一样。我知道货物对其容器依赖关系的版本进行硬编码，而不是使用maven依赖关系机制（可能是出于很好的理由，jira-> CARGO-571）

所以我的问题是：是否有其他人设法使用JSP 2.1货物和码头6x嵌入？任何建议让它工作？

任何帮助非常感谢！

好的，设法弄明白这一个。邮寄名单中的这篇文章很有帮助： http://old.nabble.com/Jetty6-version-with-maven-plugin-td16722550.html。它描述了如何使用货物定制容器的类路径，但是如果采取这种方法，则需要手动指定所有依赖关系。

我从货源地发现，这些都是jetty6x容器默认使用的依赖关系：

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")); 

的问题的有tomcat的那些，因为它们使用JSP 2.0。因此，设置CLASSPATH的时候，你需要排除那些，和包括JSP-2.1，也就是

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

<dependency> 
    <groupId>org.eclipse.jdt</groupId>

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