javax.servlet.ServletException: No adapter for handler

spring-mvc

Solution

Delete the following from your spring-servlet.xml

<bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
        <props>
            <prop key="/employee">myController</prop>
        </props>
    </property>
 </bean>
 <bean id="myController" class="org.vinay.spring_mvc.mycontroller.MyController"></bean>
 <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>

Add `<mvc:annotation-driven />` which will configure your application context automatically for use with annotated controllers.

See http://static.springsource.org/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-config-enable for more info.
