Tomcat 7和JSTL(Tomcat 7 and JSTL)

系统教程行业动态更新时间:2024-06-14 16:59:47

我用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上发布它时，发生以下错误：

SEVERE：Servlet.service（）for servlet [obliquid.servlet.Index]在上下文中使用路径[/ cp]抛出异常[绝对uri： http://java.sun.com/jsp/jstl/core : http://java.sun.com/jsp/jstl/core无法解析web.xml或与此应用程序一起部署的jar文件]

Tomcat 7具有“Spec version：Servlet 3.0，JSP 2.2，EL 2.2”，因此不包括JSTL？

当我尝试上传standard.jar和jstl.jar时，出现以下错误：

org.apache.jasper.JasperException：/jsp/index.jsp（line：3，column：62）无法从JAR文件“jndi：/ localhost / cp / WEB-INF”读取TLD“META-INF / c.tld” /lib/standard.jar“：org.apache.jasper.JasperException：无法加载或实例化TagLibraryValidator类：org.apache.taglibs.standard.tlv.JstlCoreTLV

我做了一些谷歌搜索，但我不能排除，有人说可能是因为罐子的冲突版本造成的。也许我不应该包括那些jar和使用不同的JSTL url？我的JSTL 1.1我想，是否有一个新的JSTL 1.2的URL？

我应该怎么做来解决问题，使这个应用程序运行？

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

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

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

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?

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