</project>Model class :
In package model create a managed bean java class HelloModel.java with these annotations from JSF to make this class a ManagedBean
@ManagedBean(name = "model", eager = true)
@SessionScoped
HelloModel.java as below :
package com.sample.demo.model;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

this.hello = hello;
}
public String getWorld() {
return world;
}
public void setWorld(String world) {
this.world = world;
}
}
View Class :
In view package create a HelloView.java class extends from the ManagedBean java class HelloWorld.java as below :
package com.sample.demo.view;
import javax.faces.bean.ManagedBean;

@ManagedBean(name = "hello", eager = true)
@RequestScoped
public class HelloView extends HelloModel{
public HelloView() {
super();
// TODO Auto-generated constructor stub
}
}Demo package :
In this package create FacesRewriteConfigurationProvider.java and Initializer.java and update your SampleAppliction.java as below :
SampleAppliction.java
package com.sample.demo;

as you probably did, the net might be a lot more useful than ever before.

When someone writes an post he/she maintains the idea of a user in his/her brain that how a
user can be aware of it. Thus that’s why this article is perfect.
Thanks!
This design is steller! You obviously know how to keep a reader amused.
Between your wit and your videos, I was almost moved to start
my own blog (well, almost…HaHa!) Wonderful job. I really loved what you had to say,
and more than that, how you presented it. Too cool!
Have you ever thought about adding a little bit more than just your articles?
I mean, what you say is valuable and all. However think of if you added some great photos or videos to give your posts more, “pop”!
Your content is excellent but with pics and clips, this blog could definitely be
one of the best in its field. Very good blog!
Inspiring story there. What occurred after? Good luck!
Fine way of explaining, and pleasant piece of writing to take information on the topic of my presentation topic, which i am going to present in institution of higher education.
I was curious if you ever thought of changing the page layout of your website?
Its very well written; I love what youve got to say.
But maybe you could a little more in the way of content so people could connect with it better.
Youve got an awful lot of text for only having 1 or 2 images.
Maybe you could space it out better?
Hmm is anyone else having problems with the images on this blog loading?
I’m trying to determine if its a problem on my end or if it’s the
blog. Any suggestions would be greatly appreciated.
My spouse and I stumbled over here coming from a different website and thought I might check things out.
I like what I see so i am just following you. Look forward to looking at your
web page repeatedly.
It’s amazing in favor of me to have a web page, which is beneficial designed for my knowledge.
thanks admin
Spot on with this write-up, I really think this site needs much more attention. I’ll probably
be returning to see more, thanks for the information!
Does your site have a contact page? I’m having trouble locating it but, I’d
like to shoot you an e-mail. I’ve got some ideas for your blog you might be interested
in hearing. Either way, great website and I look
forward to seeing it develop over time.
I’m gone to inform my little brother, that
he should also visit this web site on regular basis to take updated from most
recent reports.
I used to be able to find good advice from your articles.
Great article.
We are a group of volunteers and starting a new scheme in our community.
Your web site offered us with valuable information to work on. You’ve done a formidable job and our whole community will be thankful
to you.
This is a topic which is close to my heart…
Thank you! Where are your contact details though?
What’s up, its pleasant piece of writing about media print, we all know media is
a great source of facts.
Neat blog! Is your theme custom made or did you download it from somewhere?
A design like yours with a few simple adjustements would really make my blog shine.
Please let me know where you got your theme. Many thanks
Do you have any video of that? I’d care to find out more details.
Simply desire to say your article is as surprising.
The clarity in your post is simply excellent and i could assume you are an expert on this subject.
Well with your permission allow me to grab your
RSS feed to keep up to date with forthcoming post. Thanks a million and
please carry on the rewarding work.
What you composed was actually very logical.
However, what about this? suppose you were to write a awesome headline?
I ain’t saying your information isn’t good, but what if you added a post title to possibly grab a
person’s attention? I mean Primefaces Spring
Boot Hello World Example – Primefaces Tutorial is kinda vanilla.
You ought to glance at Yahoo’s front page and watch how they create post headlines to grab
viewers interested. You might try adding a video or a related picture or two to get readers excited about what you’ve written. In my opinion,
it could bring your posts a little bit more interesting.
I was able to find good advice from your blog articles.
Hey! I know this is kind of off-topic however I needed to ask.
Does managing a well-established website like yours take a massive
amount work? I’m completely new to operating a blog but I do
write in my journal daily. I’d like to start a blog so I can share my personal experience and thoughts online.
Please let me know if you have any kind of recommendations or tips
for new aspiring bloggers. Appreciate it!
There’s definately a lot to learn about this topic.
I like all of the points you’ve made.
Very good information. Lucky me I found your website
by chance (stumbleupon). I have saved it for later!
Definitely believe that which you said. Your favorite justification appeared to be on the web
the easiest thing to be aware of. I say to you, I definitely get annoyed while people think about
worries that they plainly do not know about. You managed to hit the nail upon the top and also defined out
the whole thing without having side-effects , people
can take a signal. Will probably be back to get more.
Thanks
Good day! I know this is somewhat off topic but I was wondering which blog platform
are you using for this site? I’m getting sick and tired of WordPress
because I’ve had issues with hackers and I’m looking at alternatives for another platform.
I would be fantastic if you could point me in the direction of a good platform.
Awesome article.
When someone writes an piece of writing he/she maintains
the thought of a user in his/her mind that how a user can know it.
So that’s why this piece of writing is perfect.
Thanks!
Howdy this is somewhat of off topic but I was wondering if blogs use WYSIWYG editors or if you
have to manually code with HTML. I’m starting
a blog soon but have no coding skills so I wanted to get advice from someone with experience.
Any help would be greatly appreciated!
Hello there I am so grateful I found your blog, I really found you by mistake, while I was browsing on Digg for something else,
Regardless I am here now and would just like to say many thanks for
a remarkable post and a all round enjoyable blog (I also love the theme/design), I don’t have time to go through it all at the moment but I have book-marked
it and also added in your RSS feeds, so when I have time I will
be back to read much more, Please do keep up the superb work.
I could not resist commenting. Very well written!
certainly like your web-site however you need to
take a look at the spelling on quite a few of your posts.
Many of them are rife with spelling issues and I find
it very bothersome to inform the truth on the other
hand I will definitely come back again.
This piece of writing gives clear idea designed for the new viewers of blogging,
that genuinely how to do blogging.
Do you have a spam problem on this website; I also am a blogger, and I was wanting to
know your situation; we have created some nice procedures and we are looking to
exchange methods with others, be sure to shoot me an e-mail if interested.
