Spring 3 can't able Autowire

[Ranjankp45]

Am using both mixture of HIBERNATE (spring contrainer)and JDBC(programtical) with SPRING framework
Am getting the Dependency Injection(DI) for Hibernate Module and the same is not working (DI) for my JDBC connection modules

I have the following defined class as below
*******************************

@Controller("delegate")
public class ProgramDelegate {

    @Autowired
    @Qualifier(value="programService")
    private ProgramService programService;
    public void setProgramService(ProgramService programService) {
        this.programService = programService;
    }
}
and
***
@Service("programService")
public class ProgramServiceImpl implements ProgramService{

    @Autowired
    private ProgramDao programDao;


    public void setProgramDao(ProgramDao programDao) {
        this.programDao = programDao;
    }
}

and my application-contex
*******************

<context:component-scan base-package="com.ample.mis.hibernate.*,
                                        com.ample.mis.*.*.daoImpl,

Thanks in advance

Hi!

This forum is for project Spring Integration.
But you've got an issue with integration between Spring MVC & JSF 2, so I recommend to ask similar questions here: http://forum.springsource.org/forumdisplay.php?25-Web

By your stackTrace it looks like you don't have any Spring+JSF integration: I don't see any Spring errors...
Try take a look here:
http://static.springsource.org/sprin...aceselresolver
http://www.onlinetechvision.com/?p=566
http://www.mkyong.com/jsf2/jsf-2-0-s...ration-example

Cheers,
Artem

P.S.
By the way: please, use [ CODE ] [ /CODE ] & [ HTML ] [ /HTML ] without whitespaces to show your sources.

Hi,

the above error stack shows the problem with JSF but the actual problem is am not able to auto-wire dependencies even though context:component-scan scans the component

and i can able 2 get the dependencies using this code but not able to auto-wire

ApplicationContext context =  new ClassPathXmlApplicationContext("applicationContext.xml");
ProgramService service = context.getBean("programService");

[Cleric]

Do you really think you get all with this what you want ?

<context:component-scan base-package="com.ample.mis.hibernate.*,
com.ample.mis.*.*.daoImpl,
com.ample.mis.*.*.serviceImpl,
com.ample.mis.*.*.delegate,
com.ample.mis.*.*.helper,
com.ample.mis.*.*.action"/>

How about to eat all?

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

Try to play with original suggestion: http://static.springsource.org/sprin...-autodetection and the next section.

Hi Cleric,

i already tried but its not working too

[Cleric]

So, let's try to localize and minimize the boundaries.
You say you can get "programService" bean from context, but it isn't Autowired with ProgramDao. Right?
Does your spring context see this component for bean potential?
How about to define ProgramDao as XML-bean definition instead of annotations...
Can you show an Exception about attempt to get the "programService" bean?

[Ranjankp45]

1.No, ProgramServiceImpl is auto-wired with ProgramDaoImpl
2. I have tired to configure ProgramDaoImpl in xml, i can get bean (ProgramDaoImpl) but can't able to auto-wire in ProgramServiceImpl

in ProgramDelegate i have a method called "search"

[Cleric]

i can get bean (ProgramDaoImpl) but can't able to auto-wire in ProgramServiceImpl

How many beans of ProgramDao implementation do you have?
How about to mark it with @Qualifier ?

[Ranjankp45]

1.i have only one
2.its just a try which i made

[Cleric]

Show, please, Spring Exceptions when you try to get bean from context. You still continue to show JSF error...
Try to call your @Controller like this:

ApplicationContext ctx = FacesContextUtils.getWebApplicationContext(facesContext);
ProgramDelegate delegate = ctx.getBean("delegate", ProgramDelegate.class);
delegate.search(...);

Of course, if you don't do Spring+JSF integration you should try to use this one WebApplicationContextUtils.
