如在这里:
<c:forEach items="${status.errorMessages}" var="error">
出错:
JSP Parsing Error: According to TLD or attribute directive in tag file, attribute items does not accept any expressions

但是单纯的el还是支持的

奇怪,请大家帮助我,3ks

这个和lomboz3.01有关系么~
好像是和Tomcat有关系啊~

我用的是Tomcat5.0,不知道为什么EL不能使用...

是不是在使用EL的时候web.xml还要怎么配置一下?

to benimas:

el 你按照 webapps/jsp-examples里的web.xml定义<web-app>的scheme就可以了

-----------------------------------------

运行后用到El的地方都不能显示
eg:第一行 ${1 < 2} ${1 < 2}
正常显示应该是 ${1<2} true
却没被正常显示出来

--------我的web.xml如下---------------------

请教一下是不是web.xml配置有问题?
我把jsp-examples的web.xml复制到我的web.xml中站台就不能strat了
请问应该怎么配置?

"<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">"

EL 是在JSP 2.0 中正式纳入规范的
所以用 web.xml 使用2.4的 Schema 而不是2.3的DTD

谢谢楼上的.
----------我现在web.xml改为------------------------
<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      <taglib-location>/WEB-INF/tld/c.tld</taglib-location>
    </taglib>
  </jsp-config>
  
  <welcome-file-list>

  <error-page>
    <error-code>404</error-code>

  </error-page>

</web-app>
-----------------------------------------
问题解决了>_<

jstl taglib 不用在web.xml指定的,另外，jstl1.1.1在lomboz3.01中表现正常，jstl1.06有el问题

要让tomcat 5.*支持EL，注意用下面的web.xml的写法：
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<jsp-config>
<jsp-property-group>
<description> Special property group for JSP Configuration JSP example. </description>
<display-name>JSPConfiguration</display-name>
<url-pattern>*.jsp</url-pattern>
<el-ignored>false</el-ignored>
<page-encoding>gb2312</page-encoding>
<scripting-invalid>false</scripting-invalid>
<include-coda></include-coda>

</jsp-property-group>
</jsp-config>
</web-app>

这个 version="2.4" 很重要的哟!
