java - HTTP Status 500 - Servlet.init() for servlet Dispatcher threw exception -
when i'm trying run simple html form:
<html> <head> <title>enter new page</title> </head> <body> <div id="editprespage"> <form action="editprespage.do" method="post"> <label>enter page id</label><input type="text" name="page_id"/> <label>enter header1</label><input type="text" name="h1"/> <label>enter header2</label><input type="text" name="h2"/> <label>enter header3</label><input type="text" name="h3"/> <label>enter header4</label><input type="text" name="h4"/> <label>enter page text</label><input type="text" name="page_text"/> <input type="submit" value="add new page"/> </form> </div> </body> </html> i'm getting error http status 500 - servlet.init() servlet dispatcher threw exception in browser.
in command line window (which opens when i'm running tomcat's start.batch file) i'm getting next error:
log4j:warn no appenders found logger(org.springframework.web.servlet.dispatcherservlet)
that dispatcher-servlet.xml file:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemalocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <import resource="/application.xml"/> <bean name="/editprespage.do" class="my.pack.webtier.control.editprespagecontroller" > <property name="page_manager_service" ref="page_manager_service"/> </bean> <!-- tried using annotations --> <!-- <context:component-scan base-package="my.pack"/> --> </beans> that's web.xml file:

i've searched reply requirements - , didn't found one.
you map dispatcher on *.do:
<servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> but controller mapped on url without .do:
@requestmapping("/editprespage") try changing to:
@requestmapping("/editprespage.do") java eclipse spring-mvc tomcat7
