NoSuchBeanDefinitionException with spring and gwt (requestFactory)

I get this error with a gwt (using requestfactory) and spring

Code:

---

    org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [org.calibra.server.service.AccountService] is defined: expected single bean but found 0:
        at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:271)
        at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1101)
        at org.calibra.server.SpringServiceLocator.getInstance(SpringServiceLocator.java:24)
        at com.google.web.bindery.requestfactory.server.LocatorServiceLayer.createServiceInstance(LocatorServiceLayer.java:56)

---

My service locator

Code:

---

    public class SpringServiceLocator implements ServiceLocator {
        @Override
        public Object getInstance(Class<?> clazz) {
            ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(               
                RequestFactoryServlet.getThreadLocalServletContext());
            return context.getBean(clazz);
        }
    }

---

My spring service

Code:

---

    @Service
    public class AccountServiceImpl implements AccountService{
        @Override
        public void addNewAccount(Account account) {
          ...
        }

        @Override
        public List<Account> loadAllAccounts() {
            ...
        }

    }

---

Gwt requestContext

Code:

---

    @Service(value=AccountService.class, locator=SpringServiceLocator.class)
    public interface AccountRequest extends RequestContext {
   
        Request<Void> addNewAccount(AccountProxy account);

        Request<List<AccountProxy>> loadAllAccounts();
 
    }

---

My web.xml

Code:

---

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

    <servlet-name>gwtRequest</servlet-name>

my dispatcher-servlet.xml

Code:

---

<context:annotation-config />
<context:component-scan base-package="com.calibra" />

---

I don't understand why i have 0 bean

Any idea?

There is nothing that is loading your dispatcher-servlet.xml. Your beans should all be loaded in the applicationContext.xml.

I will need to add dispatcher-servlet.xml to my config, so i will have 2 servlet.

I saw this file: https://code.google.com/p/gwtcontact...EB-INF/web.xml

Don't know it's is the good way to do it. Will test it tonight.

That won't work either... You can only access beans loaded by the ContextLoaderListener you cannot access beans from servlet x loaded by servlet y. So as mentioned the beans must be loaded with the ContextLoaderListener.

ok, my dispatcher-servlet.xml is not loaded, so i need to add the contain of this file to applicationContext.xml ?

Quote:

---

<context:annotation-config />
<context:component-scan base-package="com.calibra" />

---

and maybe will need to add

Quote:

---

<bean id="accountService" class="org.calibra.server.service.AccountServiceIm pl"/>

---

You only need to component-scan (annotation-config is implied when using componet-scan). Component-scanning would be pretty useless if one would still need to configure the services explicitly.

ok thank, will try tonigh and give you the result.

i put

Quote:

<context:component-scan base-package="com.calibra" />

in applicationContex.xml file, but i got the same error.

I posted all the source there: http://filebin.ca/CRE3HbzFunH

I'm not that familair with GWT but one thing I noticed is that you are trying to get the AccountServiceImpl whereas you should get the interface (due to proxy creation for instance).

Also make sure that everything is deployed correctly (you probably want to enable debug logging for spring to see which beans are registered at startup).
