Why is Target Unreachable, identifier resolved to

问题:

This question already has an answer here:

• Identifying and solving javax.el.PropertyNotFoundException: Target Unreachable 13 answers
• Spring JSF integration: how to inject a Spring component/service in JSF managed bean? 3 answers

People are marking this a duplicate, but if you look at my answer below, you will see why it is different.

I am using STS, weblogic, and primefaces 5.3 and I keep getting the error "Target Unreachable, identifier 'dtObservationsView' resolved to null".

This is a spring application using REST.

The application runs perfectly well on tomcat, but not when I deploy to weblogic.

I have read through the posted response at dentifying and solving javax.el.PropertyNotFoundException: Target Unreachable but it has not yielded any solution that works.

I have also tried WebLogic Reference, but I am still getting the same error.

TERMS and DEFINITIONS:

CDI: This is from the first link above:

Contexts and Dependency Injection for Java EE

Contexts and Dependency Injection for Java EE (CDI) is one of several Java EE features that help to knit together the web tier and the transactional tier of the Java EE platform. CDI is a set of services that, used together, make it easy for developers to use enterprise beans along with JavaServer Faces technology in web applications. Designed for use with stateful objects, CDI also has many broader uses, allowing developers a great deal of flexibility to integrate various kinds of components in a loosely coupled but typesafe way.

SPRING: This from the 5th link above: The Spring Framework is an application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE (Enterprise Edition) platform. Although the framework does not impose any specific programming model, it has become popular in the Java community as an alternative to, replacement for, or even addition to the Enterprise JavaBeans (EJB) model. The Spring Framework is open source.

NOTE:

I gave the above definitions to show that there are two places where dependency injection can occur when you deploy primefaces to Weblogic when you are developing with Spring.
One is with CDI and the other is with Spring. It is important to understand this because, at least from I have read and experienced, you should not mix the annotations for spring and CDI.

Tomcat is much more forgiving when it comes to primefaces deployment than Weblogic. My application worked perfectly fine on tomcat, but with Weblogic, I had all kinds of problems. The first one being the javax-el-propertynotfoundexception-target-unreachable exception. The second link above, goes into a pretty good definition of what you need to do make things work properly with primefaces.

The 3rd link is my post to stackflow, where I was seeking an answer the exception I was getting with Weblogic. If I can get this document posted as an answer there in a readable format, I will do that.

ARCHITECTURE:

So there is a similar architecture with primefaces that I believe mirrors the Spring MVC pattern. In Spring MVC, the Controller is code that gets invoked whenever there is an HTTP request made to the application server, i.e., Tomcat or Weblogic. Weblogic is needed if you wish to user EJB's because Tomcat is servlet container only, and doesn't understand EJBs. Tomcat works very well with Spring since Spring does everything in servlets. So, if you are not using EJBs, I believe that Tomcat is the way to go since it is open source and requires no licensing fees.

In my case, however, the client is only allowing Weblogic, hence the issues I started dealing with.

The next layer in the MVC pattern is the service layer and below that is the repository layer. So it is Controller -> Service -> Repository.

Normally in Spring MVC, the Controller autotwires the Serivice with the @Autowired, and the Service autowires the Repository, which will make user of the @Entity beans. Entity beans in Hibernate are just POJO's with the @Entity annotation. These object get persisted to the database.

In Primefaces, at least based on my limited knowledge, there is a ManagedBean and a ManagedProperty.

Both Primefaces and Spring have annotations that inject the relationships of these various objects in java.

In the case of Spring, you have @Controller or @RestController, @Service, and @Repository. This is not a complete list, but it is the ones I typically use. In Primefaces, you have @ManagedBean and @ManagedProperty. There may be others, but this is what I have used. A @ManagedProperty is like the @Autowired in Spring.

So a ManagedBean is like this:

    @ManagedBean(name="observationsView", eager=true)
public class ObservationsView implements Serializable {

    @ManagedProperty( value = "#{observationService}")
    private ObservationService observationService;

    ...
}

@ManagedBean(name = "observationService")
@ApplicationScoped
public class ObservationServiceImpl implements ObservationService, Serializable {
    @ManagedProperty( value = "#{observationDao}")
    private ObservationDao observationDao;

    ...
}

@ManagedBean(name = "observationDao")
@ApplicationScoped
public class ObservationDaoImpl implements ObservationDao, Serializable{

    @ManagedProperty( value = "#{daoHelper}")
    private DaoHelper daoHelper;

    ...

}

You will note that a ManagedBean "autowires" the ManagedProperty that it needs.

MISTAKES TO AVOID:

1. Make sure that you implement the Serializable for all your managed beans.

2. Make sure that you create the getters and setters for all of the ManagedProperty's, so that the java reflection can get and set them.

   Here is an example:

   @ManagedBean(name = "observationService")
   

   @ApplicationScoped public class ObservationServiceImpl implements ObservationService, Serializable {

   /**
    * 
    */
   private static final long serialVersionUID = -7242896804221503769L;
   
   /**
    * @return the observationDao
    */
   public ObservationDao getObservationDao() {
       return observationDao;
   }
   
   /**
    * @param observationDao the observationDao to set
    */
   public void setObservationDao(ObservationDao observationDao) {
       this.observationDao = observationDao;
   }
   
   @ManagedProperty( value = "#{observationDao}")
   private ObservationDao observationDao;
   
   public List<Observation> getObservationsByFein( Long fein ) throws Exception{
       return this.observationDao.findByFein(fein);
   }
   
   public List<Observation> getObservations() throws Exception{
       return this.observationDao.findAll();
   }
   

   }

If you don't create the setters and getters, then Primefaces will not work, at least not in Weblogic.

3. On your @ManagedPropery(), make sure use use 'value = "bean name"', not just @ManagedProperty("bean name").

4. Name all your managed beans with the @ManagedBean(name = "bean name"). I am not familiar with the scoping rules.

5. Do not mix the Spring annotation with the Primefaces annotations.

6. Make sure that you are using the javax.faces.bean annotations:

   import javax.faces.bean.ApplicationScoped;
   
   import javax.faces.bean.ManagedBean;
   
   import javax.faces.bean.ManagedProperty;
   

   Do not use the:

   import org.springframework.web.bind.annotation.*
   

In STS, make sure that the project Properties -> Spring -> Project Builders -> AOP Reference Model Builder is disabled if you added the AOP namespace in the servlet-context.xml file.
