Tomcat 5.5和JSTL 1.2上的ELException [英] ELException on Tomcat 5.5 and JSTL 1.2

问题描述

• Apache Tomcat 5.5
• Servlet/JSP:2.4/2.0，根据 http://tomcat.apache.org/whichversion.html
.WAR中的
• JSTL:1.2

• Apache Tomcat 5.5
• Servlet/JSP: 2.4/2.0 according to http://tomcat.apache.org/whichversion.html
• JSTL in .WAR: 1.2

但是我仍然得到一个 java.lang.NoClassDefFoundError: javax/el/ELException

But I still get a java.lang.NoClassDefFoundError: javax/el/ELException

据我在SO处的阅读问题所理解的是，ELException类已被移动，并且容器应包括该类.以前在JSTL 1.1中，它是在JSTL .jar中提供的.由于容器是JSP 2.0，对此我感到困惑.

From what I have understood by reading question here at SO is that the ELException class has been moved and the container should include it. Previously in JSTL 1.1 it was provided in the JSTL .jar. Since the container is JSP 2.0 I am confused about this.

您需要执行以下任一操作

You need to do either of following

将Tomcat容器升级到最新版本

Upgrade the Tomcat container to latest

或

将JSTL库降级到1.0/1.1，可以从Apache Tag lib实现中获得: http ://tomcat.apache.org/taglibs/standard/

downgrade the JSTL library to 1.0/1.1 which can be available here from Apache Tag lib implementation : http://tomcat.apache.org/taglibs/standard/

摘自Apache库下载，以实现与JSTL版本到Tomcat版本的兼容性

excerpt from Apache library download for Compatibility to JSTL version to Tomcat Version

您正在使用不兼容的JSP 2.0和JSTL 1.2.因此，某些类可能会升级或降级

as you can see , you are using the JSP 2.0 and JSTL 1.2 which in-compatible. Hence some classes might be upgraded or downgraded
