Improving the OFBiz User Interface with JPA

Hi all,

as I announced recently with the email "OFBiz Delegator that uses JPA", 
I am working now on a drop in replacement that uses JPA as entity model. 
While the work on the replacement is still in progress, a JAR with the 
JPA entities has reached a beta state. It can be downloaded from here 
(about 6MB, source code included):

http://www.mk-multimedia.de/ofbiz/ofbiz-entity-jpa.jar

Because JPA (and J2EE) does not only offer a standard replacement for 
the database layer but can also improve and accelerate the development 
of the presentation layer, I like to suggest to consider using (de 
facto) standard libraries like PrimeFaces 
(http://www.primefaces.org/showcase/) for improving the UI.

For those of you who are not aware about the power of JPA in an IDE, 
here is a little tutorial:



Install NetBeans with J2EE-Support
==================================

1. Download NetBeans J2EE Bundle:
	https://netbeans.org/downloads/
2. Install NetBeans and Glassfish:
	https://netbeans.org/community/releases/82/install.html


Setup Glassfish
===============

1. Start NetBeans
2. Klick on the "Services" tab, right click on "Servers" -> add
3. Select "GlassFish Server" and enter a name
4. Set the installation location and choose "Local Domain"
5. Choose a domain location and ports (watch out for conflicts with 
OFBiz ports!)


Create a database connection, connection pool and JDBC resource
===============================================================

IMPORTANT: My JPA library expects a JDBC resource with the JNDI name 
"jdbc/ofbiz" (specified in "/META-INF/persistence.xml")!

-> https://netbeans.org/kb/docs/javaee/ecommerce/setup.html


Create a Web-Application
========================

1. File -> New Project
2. Choose the following Project:
	Categories:		Java Web
	Projects:		Web Application
3. Enter the Project Name, e.g. "OFBiz-UI"
4. Choose the Server Settings:
	Server:			Choose the installed one
	Java EE Version:	Has to be "Java EE 7 Web"
	Context-Path:		The absolute path of the OFBiz-UI URL
5. Select the framework:
	a) Choose JavaServer Faces
	b) Click on "Components" tab and select "PrimeFaces"


Create a UI for an entity
=========================

1. Download the JAR with the JPA entities:
	http://www.mk-multimedia.de/ofbiz/ofbiz-entity-jpa.jar
2. Add the JAR to the libraries of the Web-Application
3. Right click on the Web-Application -> New -> Other:
	Categories:			Persistence
	File Types:			JSF Pages from Entity Classes
4. Choose only one entity Class, e.g. 
"org.apache.ofbiz.party.party.Party", click "Add >" and disable "Include 
Referenced Classes"
5. Choose packages, folders and templates:
	Session Bean Package:		org.apache.ofbiz.party.ejb
	JSF Classes Package:		org.apache.ofbiz.party.jsf
	JSF Pages Folder:		/
	Localization Bundle Name:	/org/apache/ofbiz/party/PartyBundle
	Choose Template:		PrimeFaces
6. Choose Provider and Database (as specified in 
"/META-INF/persistence.xml"):
	Persistence Unit Name:		org.apache.ofbiz
	Data Source:			jdbc/ofbiz
7. Right click on the Web-Application -> Run


Improvements:
=============

- Use Payara instead of Glassfish because it is much more reliable
   -> http://www.payara.fish/downloads

- Use PrimeFaces 6.0 community release
   -> http://www.primefaces.org/downloads

- Use PrimeFaces community theme
   -> http://www.primefaces.org/themes

Hi Markus,

I have checked out the contents of the jar file and the entity beans look comprehensive. 

If you are still working on this, can you provide a minimum patch to OFBiz trunk version so that we can test them out in stages. 

Personally, I am in favor of adopting JPA and agree it will be good for OFBiz.

James Yong

Re: Improving the OFBiz User Interface with JPA

Makus,

I'm working with 2 peers on a new project based on OFBiz to create a custom
app capable to interact with OFBiz db using Spring Framework + Angular 2. We
just started from scratch building our own ORM (Hibernate based)
implementation for OFBiz but now I found you already did a really great work
hence now I wonder if your are maintaining an updated repository which we
could use, test and help to you improving it instead of continue our own
implementation.

Thanks,
Victor
