please advise why getting exception, , how fix it.

edit: following configuration files:

1- .springbeans:

<?xml version="1.0" encoding="utf-8"?> <beansprojectdescription>     <version>1</version>     <pluginversion><![cdata[2.9.0.201203011806-release]]></pluginversion>     <configsuffixes>         <configsuffix><![cdata[xml]]></configsuffix>     </configsuffixes>     <enableimports><![cdata[false]]></enableimports>     <configs>         <config>src/main/webapp/web-inf/checkout-servlet.xml</config>     </configs>     <configsets>     </configsets> </beansprojectdescription> 

2- web.xml:

<web-app>   <display-name>checkout</display-name>    <servlet>     <servlet-name>checkout</servlet-name>     <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>     <load-on-startup>1</load-on-startup>   </servlet>    <servlet-mapping>     <servlet-name>checkout</servlet-name>     <url-pattern>*.action</url-pattern>   </servlet-mapping>  </web-app> 

3- checkout-servlet.xml:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:context="http://www.springframework.org/schema/context"     xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">      <context:component-scan base-package="com.myapp"/>      <bean id="myservice" class="com.myapp.myservice"/>  </beans> 

also when trying access page in application, exception:

http status 404 - servlet checkout not available  type status report  message servlet checkout not available  description requested resource (servlet checkout not available) not available. apache tomcat/7.0.22 

you need add "maven dependency" in deployment assembly

  • right click on project , choose properties.
  • click on deployment assembly.
  • click add
  • click on "java build path entries"
  • select maven dependencies"
  • click finish.

rebuild , deploy again

note: applicable non maven project.
