Can you post the bit of the web.xml where you register the ContextLoaderListener? It should look something like:

Code:

<servlet> <servlet-name>context</servlet-name> <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet>

or for servlet 2.4 (preferred method):

Code:

<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

my web.xml

Code:

<?xml version="1.0" ?> <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="2.3">  <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <error-page> <error-code>404</error-code> <location>/error.jsp</location> </error-page> <servlet> <servlet-name>reg</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/regcofig.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>reg</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>

my regcofig.xml

Code:

<?xml version="1.0" ?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <beans>  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass"> <value>org.springframework.web.servlet.view.JstlView</value> </property> <property name="prefix"><value>/jsp/</value></property> <property name="suffix"><value>.jsp</value></property> </bean> <bean id="RegisterValidator" class="net.xia.validator.RegisterValidator"/>  <bean id="RegisterAction" class="net.xia.action.RegisterAction"> <property name="commandName"> <value>RegisterInfo</value> </property> <property name="commandClass"> <value>net.xia.validator.RegisterInfo</value> </property> <property name="validator"> <ref bean="RegisterValidator"/> </property> <property name="formView"> <value>register</value> </property> <property name="successView"> <value>registersuccess</value> </property> </bean>  <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="/register.do">RegisterAction</prop> </props> </property> </bean> </beans>

???why?

Your web.xml doesn't appear to be valid. The version="2.3" should be version="2.4"

Thanks for helping me!
