JSTL中无法使用el表达式的解决方法(转)

1.到jsp页面加上 

<%@ taglib uri="http://java.sun.com/jstl/core"prefix="c"%> 

加入 jstl.jar 和standard.jar到web-inf/lib下就可以解析el表达式了 

或者在jsp页面加上:<%@ page isELIgnored="false" %> 

2.如果还不可以直接到web.xml中配置如下代码： 

<jsp-config> 

        <jsp-property-group> 

            <description>指定JSP文件的配置属性</description> 

            <display-name>jspConfiguration</display-name> 

            <url-pattern>*.jsp</url-pattern> 

            <el-ignored>false</el-ignored> 

            <page-encoding>utf-8</page-encoding> 

            <scripting-invalid>false</scripting-invalid> 

            <include-prelude></include-prelude> 

            <include-coda></include-coda> 

        </jsp-property-group> 

        <jsp-property-group> 

            <description>指定htm文件的配置属性</description> 

            <display-name>jspConfiguration</display-name> 

            <url-pattern>*.htm</url-pattern> 

            <el-ignored>false</el-ignored> 

            <page-encoding>utf-8</page-encoding> 

            <scripting-invalid>false</scripting-invalid> 

            <include-prelude></include-prelude> 

            <include-coda></include-coda> 

        </jsp-property-group> 

        <jsp-property-group> 

            <description>指定html文件的配置属性</description> 

            <display-name>jspConfiguration</display-name> 

            <url-pattern>*.html</url-pattern> 

            <el-ignored>false</el-ignored> 

            <page-encoding>utf-8</page-encoding> 

            <scripting-invalid>false</scripting-invalid> 

            <include-prelude></include-prelude> 

            <include-coda></include-coda> 

        </jsp-property-group> 

    </jsp-config> 

一般不会出现问题了
