Tomcat 7和JSTL [英] Tomcat 7 and JSTL

问题描述

我使用Eclipse Tomcat编写了一个Web应用程序，它可以在我的本地Tomcat 7上运行，当我尝试在Tomcat 7上在线发布时，我遇到以下错误：

I wrote a web application with Eclipse Tomcat and it works on my local Tomcat 7, when I tried to publish it online on a Tomcat 7, I had the following error:

SEVERE：servlet [obliquid.servlet.Index]的Servlet.service（）在路径[/ cp]的上下文中抛出异常[绝对uri： http：/ /java.sun.com/jsp/jstl/core 无法在web.xml或使用此应用程序部署的jar文件中解析]

SEVERE: Servlet.service() for servlet [obliquid.servlet.Index] in context with path [/cp] threw exception [The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application]

Tomcat 7有Spec版本：Servlet 3.0，JSP 2.2，EL 2.2，所以不包括JSTL？

Tomcat 7 has "Spec versions: Servlet 3.0, JSP 2.2, EL 2.2", so JSTL is not included?

当我试过上传standard.jar和jstl.jar我遇到以下错误：

When I tried to upload standard.jar and jstl.jar I had the following error:

org.apache.jasper.JasperException：/ jsp / index。 jsp（第3行，第62列）无法从JAR文件jndi：/localhost/cp/WEB-INF/lib/standard.jar中读取TLDMETA-INF / c.tld：org.apache.jasper .JasperException：无法加载或实例化TagLibraryValidator类：org.apache.taglibs.standard。 tlv.JstlCoreTLV

org.apache.jasper.JasperException: /jsp/index.jsp (line: 3, column: 62) Unable to read TLD "META-INF/c.tld" from JAR file "jndi:/localhost/cp/WEB-INF/lib/standard.jar": org.apache.jasper.JasperException: Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV

我做了一些谷歌搜索，但我无法解决它，有些人说它可能是由相互冲突的版本引起的罐子。也许我不应该包括那些罐子并使用不同的JSTL网址？我的JSTL 1.1我认为，是否有JSTL 1.2的新URL？

I did some googling, but I couldn't sort it out, some said it could be caused by conflicting versions of the jars. Maybe I should not include those jars and use a different JSTL url? Mine is for JSTL 1.1 I think, is there a new URL for JSTL 1.2?

我该怎么做才能解决问题并使这个应用程序运行？

What should I do to solve the problem and make this application run?

推荐答案

Tomcat从未包含过JSTL。

Tomcat has never included JSTL.

你应该把jstl和标准罐子放进去在 WEB-INF / lib （你已经完成了），并确保你有权阅读它们（chmod）

You should put the jstl and standard jars in WEB-INF/lib (you've done that), and make sure you have the permissions to read them (chmod)

你的URI是正确的，它应该有用（在这里工作）

Your URI is correct and it should work (works here)
