javax/servlet/jsp/el/VariableResolver

This is JSP2.0 library class. you need to download and set to classpath or put in WEB-INF/lib

You can get that library by download this and install to hard drive.
http://www.signal42.com/mirrors/apache/jakarta/tomcat-5/v5.0.27/bin/jakarta-tomcat-5.0.27.exe
The library located in

C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib\jsp-api.jar

hi,sompol_kiatkamolchai
  i am sorry to interrput you,when i use resin2.1.9,and copy tomcat\common\lib|*.jar in resin2.1.9\lib,it can work ,but
<c:out value="${idCommunity.communityName}"/>
can work,but ${idCommunity.communityName} can not work,
and when i use myself taglib it will say:
/communitmedical/webapp/system/UserManage.jsp:4: `http://beltino.com/util/js'
has no matching taglib-uri.  The taglib uri must match a taglib-uri for
a taglib specified in the web.xml or implicitly in a taglib.tld in the
tag jar.

or some error like this

beltUtil.tld:6 unknown element `xsi:schemaLocation' in `taglib'

this is my taglib tld:
