Hi,
Here is the scenario:
The
JSP file is :
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/tlds/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/tlds/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/tlds/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/tlds/struts-nested.tld" prefix="nested" %>
<head>
<title>JSP Page</title>
</head>
<html:html>
<html:base/>
<body bgcolor="#FFFFFF">
<html:link forward="listUser">List User</html:link>
Comment out
</body>
</html:html>
the struts-config.xml file is :
?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD
Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
<form-beans>
<form-bean name="createForm" type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="name" type="java.lang.String" />
<form-property name="address" type="java.lang.String" />
</form-bean>
<form-bean name="indexForm" type="org.apache.struts.validator.DynaValidatorForm"/>
<form-bean name="listForm" type="org.Hibernate.struts.form.UserListForm"/>
</form-beans>
<global-forwards>
<forwardname="listUser" path="/list.do"/>
</global-forwards>
<action-mappings>
<action
path="/list"
type="org.Hibernate.struts.action.UserListAction"
name="listForm"
input="/jsp/index.jsp"
<forward name="refresh" path=""/>
</action>
</action-mappings>
</struts-config>
when I run it, I got the following error message:
exception

Please help what the problem is.
