本文介绍了解决在Tomcat5.5部署中遇到的MissingClass:javax/el/ValueExpression错误的方法。该问题源于使用的webmodule版本不匹配，通过在$CATALINA_HOMEcommonlib目录下添加jsp-api-2.1-6.0.2.jar文件可以解决此问题。
碰到这问题是，因为在Tomcat5.5部署时发生了错误
Missing Class: javax/el/ValueExpression

因为5.5的web module用的是2.4，如果用6.0就是2.5,7.0就是3.0的web module了
后两者都不会出现这问题

将jsp-api-2.1-6.0.2.jar 到 $CATALINE-HOME\common\lib.可解决问题

部署不同版本Tomcat引发的jstl java.lang.NoClassDefFoundError javaxelValueExpression问题

问题说明：                今天碰到一问题，家里新增测试功能没有问题，而放到现场部署，页面抛这个错：java.lang.NoClassDefFoundError: javax/el/ExpressionFactory 后来对比才发现，现场使用的是Tomcat5.5的版本发布，而我使用的是6.0的版本，网上了解确实存在jstl支持的问题。  解决方案： 更新javax.el.j
