Error Message.

Unable to create managed bean message. The following problems were found: - Property helloWorld for managed bean message does not exist. Check that appropriate getter and/or setter methods exist.

1. This message comes in JSF when you are Injecting JSF bean to another Bean using @ManagedProperty.
2. Taking below Example of Injecting HelloWorld.java to Message.java
   HelloWorld.java

   package com.chillyfacts.com;
   import javax.faces.bean.ManagedBean;
   import javax.faces.bean.SessionScoped;
   @ManagedBean(name = "hello")
   @SessionScoped
   public class HelloWorld {
       private String name;
       public HelloWorld() {
       }
       public String getName() {
           return name;
       }
       public void setName(String name) {
           this.name = name;
       }
   }
   
   

3. There will be error if you just Write like this.
   Message.java

   package com.chillyfacts.com;
   import javax.faces.bean.ManagedBean;
   import javax.faces.bean.ManagedProperty;
   import javax.faces.bean.RequestScoped;
   @ManagedBean
   @RequestScoped
   public class Message {
       @ManagedProperty(value = "#{hello}")
       private HelloWorld helloWorld;
   
       // Any other Code   
       public Message() {
       }
   }
   

4. Solution.
   Update the Message.java with Getters and Setters of the bean.
   Message.java

   package com.chillyfacts.com;
   import javax.faces.bean.ManagedBean;
   import javax.faces.bean.ManagedProperty;
   import javax.faces.bean.RequestScoped;
   @ManagedBean
   @RequestScoped
   public class Message {
       @ManagedProperty(value = "#{hello}")
       private HelloWorld helloWorld;
       public void setHelloWorld(HelloWorld helloWorld) {
           this.helloWorld = helloWorld;
       }
       public HelloWorld getHelloWorld() {
           return helloWorld;
       }
       
       // Any other Code   
   
       public Message() {
       }
       
   }
   

   Error should have gone now.
