Error @Autowired Service in Virgo [message #786595] Mon, 30 January 2012 11:04 Go to next message
Eclipse UserFriend
Hi, I have 2 bundles:
Bundle 1. Export a service. This is the code
services-spring.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:osgi="http://www.springframework.org/schema/osgi"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/osgi http://www.springframework.org/schema/osgi/spring-osgi.xsd">
    <!--<osgi:service interface="com.divux.onex.comunication.Login" ref="login"/> -->
    
    <osgi:service id="comunicationTemplateService" interface="com.company.admin.templateone.inter.ComunicationTemplate" ref="comunicationTemplate"/>
</beans>


bundle-context-spring.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:mvc="http://www.springframework.org/schema/mvc"
        xmlns:beans="http://www.springframework.org/schema/beans"
        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
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
  
   <context:component-scan base-package="com.company.admin.templateone.impl" />
</beans>

I scan the package com.company.admin.templateone.impl because there are the Class:

@Component("comunicationTemplate")
public class ComunicationTemplateImpl implements ComunicationTemplate {

    @Override
    public String getName() {
        return "TemplateOne";
    }

    }


Fine.

The Code of the WAB Service Consumer is this:

ApplicationContext.xml
....
<osgi:reference id="comunicationTemplate" interface="com.company.admin.templateone.inter.ComunicationTemplate"/>


company-servlet.xml
 <context:component-scan  base-package="com.company.admin.core.controller"></context:component-scan>   
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
   
    <mvc:annotation-driven/>   
    <mvc:resources mapping="/resources/**" location="/resources/"/>


And the class where I have the @Autowired is this:

@Controller
public class IndexController {
    @Autowired
     ComunicationTemplate comunicationTemplate;


    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String showIndex(HttpServletRequest request) {

        return "index";
    }
}



But when I go to the index page of the Consumer Web Bundle (WAB) the application show an error message:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.company.admin.templateone.inter.ComunicationTemplate] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

I'm using Virgo 3.0.2 Release. The service bundle provider export the package of the Interface and the WAB consumer import the same package.

Sorry for the long post, but I dont know what am I doind wrong. Why am I having this error?

Also this WAB is using Spring security and Snaps libraries.

Do you use Osgi Aware Application Context in your wab?

 <context-param>
        <param-name>contextClass</param-name>
        <param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
    </context-param>

Hi Dmitry thanks for the quick answer.
I solve the problem.

The problem was this: In the web.xml I had this

web.xml
<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:applicationContext-business.xml
            /WEB-INF/security-app-context.xml
          
        </param-value>
    </context-param>


but I have the Reference configuration in the applicationContext.xml file and in the web.xml I don't mention this file. I solved this problem adding this file in the web.xml

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:applicationContext-business.xml
            /WEB-INF/security-app-context.xml
            /WEB-INF/applicationContext.xml
        </param-value>
    </context-param>


Thanks.

Sorry Dmitry I have other problem. The bundle consumer is a HOST in Snaps Virgo, the other is a normal bundle. And the host can consume very well the service of the normal bundle. But when I traying to consume a service from a snap bundle they can't do it if the osgi:reference is not declared in the ApplicationContext.xml file of the Host.

Why does it happend?

Sorry - I am not sure I fully understand an issue.

You have a service provider bundle (A), snap host (H) and a snap child bundle (C). When A publishes service - H consumes it without an issue, but when you are publishing service from C - H does not see it.

Is this correct?

If so - yes this will so, because C is started after H by its definition. Host must be fully active for child to come up. You can't have Host depend on or require service published by a Snap child. Timing issue. You could configure a reference collection (list/set) in the host vs. a reference and deal with dynamics that way.

I am not sure what C is publishing that you need in H, but you better be sure that service interface that C publishes is not part of the C bundle/wab. Move it out to a shared bundle.

Let me know if I understood the problem correctly.

Hi Dmitry,

That is not the problem. I have the service provider (A), snap Host(H) and a snap child bundle (C). C wants to consume a service from A. But when I declare 
<osgi:list id="comunicationTemplate" interface="com.company.admin.templateone.inter.ComunicationTemplate"/>
in my ApplicationContext.xml to receive the service and autowired in an Object in a Class of C there is a problem, because the application doesn't find a bean for Autowired that object.

But when I put 
<osgi:list id="comunicationTemplate" interface="com.company.admin.templateone.inter.ComunicationTemplate"/>
in ApplicationContext.xml of the Host this work fine. Why can't I consume a service from a Child??

Can you include your Child web.xml configuration?

I think it might be because you are trying to load applicationContext in the child as a ROOT context. Host and Child share serveltContext. You might need to scope your application context for the child to the servlet and remove context-param and ContextLoadListener from web.xml of the child snap.

<servlet>
        <servlet-name>snap</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                /WEB-INF/spring/servlet/*.xml
            </param-value>
        </init-param>
        <init-param>
            <param-name>contextClass</param-name>
            <param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>

I don't what I need to change in web.xml child to load the applicationContext of child, not applicationContext of the Host

Try to scope your app context to a servlet:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">

    <display-name>template</display-name>


  <!-- DISPATCHER SERVLET CONFIG -->
    <servlet>
        <servlet-name>template</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                <path to your spring config here>
            </param-value>
        </init-param>
        <init-param>
            <param-name>contextClass</param-name>
            <param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
        </init-param>
    </servlet>

    <servlet-mapping>
        <servlet-name>template</servlet-name>
        <url-pattern>/web/*</url-pattern>
    </servlet-mapping>
