controller not getting call on start up

[sam White]

Hi,

I have written a sample EAR project, the EAR file consists of EJB3 and Spring 3.0.6 in the WAR module.
Deployment gone through successfully, but the controller is not getting call.

Here is my mvc-dispatcher-servlet.xml file:

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	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">

	<context:component-scan base-package="ix.houseware.category.web.controller" />

	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix">
			<value>/WEB-INF/pages/</value>
		</property>
		<property name="suffix">
			<value>.jsp</value>
		</property>
	</bean>

</beans>

web.xml file:

<web-app id="WebApp_ID" version="2.4"

        logger.info("calling CalculatorFinderController");
        try {
            InitialContext ic = new InitialContext();
            // Obtain the application component's ENC
            CalculatorLocal remote = (CalculatorLocal) ic.lookup("java:app/category6-ws-ejb/CalculatorBean!ix.houseware.category.CalculatorLocal");

Any suggestion would be very appreciated.

This is confusing me. Looks like you have two different things mixed up.

<servlet>  
        <servlet-name>mvc-dispatcher</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
  
    <servlet-mapping>  
        <servlet-name>mvc-dispatcher</servlet-name>  
        <url-pattern>/</url-pattern>  
    </servlet-mapping>  
  
    <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>  
    </context-param>  

The context param is for the ContextLoaderListener creating an ApplicationContext for just the middle tier beans. The mvc-dispatcher-servlet.xml is following the naming convention of the file that the DispatcherServlet looks for to create the other ApplicationContext that is just for the web layer beans.

In a Spring MVC app you should have 2 ApplicationContexts. One for middle tier beans using ContextLoaderLister and one for the web layer beans using DispatcherServlet. To tell the DispatcherServlet where its config file is, you use the init-param tag in the <servlet> tag in your web.xml
