Hello forum,

I have the following situation:

I´ve integrated JSF and Spring in my application. So, when I debug my code, I can see that my managed beans ( I´ve put a resolver in faces-config.xml to indicate that Spring have to resolve the properties name ) are instantiated twice.

Does anyone knows why that´s occurs?:confused:

If they are instantiated twice your configuration is somehow loading the application context twice.

Hi chudak,

thanks for answer my question.


I´ve configurated my web.xml like the following:


<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/Spring.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListe ner</listener-class>
</listener>


and to get my beans I have the following code:



public static synchronized ApplicationContext getSpringContext() {

if(springContext == null){
springContext = new ClassPathXmlApplicationContext("Spring.xml");
}


return springContext;
}
public static synchronized Object getBean(String name){
return getSpringContext().getBean(name);
}


Do you think that there is something wrong???

Thanks in advance.

You are loading the application context in your web.xml and then loading it again statically. Just like I said: you are loading your context twice.

How could I retrieve the Context previously loaded by the server?? ( the current context )

Thank´s again!

Why are you trying to access beans from the context? You're missing the whole point of dependency INJECTION. With a web application it is usually very easy to have spring wire up everything for you. This works with spring MVC and struts.

The only time I needed to access beans directly from the context was in a swing application and in MDB's that used components that spring managed.

I´ve changed a bean and now, my attribute is injected by the context file. But I still can see that my managed bean JSF is still instantiated twice.
But the second instance of my managed bean is a proxy.

Do you have any idea why this is happening? Cause I´ve removed the second instance is a proxy...

Did you remove the static initializer that creates your bean factory outside of the web.xml?

Post your whole web.xml (use code tags)

Hey, I don't want to interrupt this current thread, but next time please post web-related threads in the Web forum. This forum category is intended for the Spring Integration project.

Thanks,

Sorry Mark.

I´ve created this thread here cause the problem occured after the integration of the Spring and JSF.

Sorry for my mistake!

No problem. As you can probably imagine, it's a common mistake since "integration" sounds very generic. However, we have a project called "Spring Integration", and this forum category is intended for that.

Spring Integration doesn't mean 'integrating' spring in your application. It means the Spring Integration Framework (EAI patterns):

Mark, you may want to just move this thread to the appropriate forum. It's clearly misplaced.
