An easy way to connect JSF with Adobe FLEX




Using Adobe Flex together with other technologys like JavaServer Faces, Struts or Spring Web Flow is not an easy task, because the embedded Flash-file interacts in its own world and from the sight of its surrounding JSF/JSP/HTML-Code, it is an foreign object. There exists some approaches to connect these different worlds like the jsf-flex project or the Exadel Fiji.

I am now showing you an another way, how you can connect Flex with JavaServer Faces. You are able to develop each Project (Flex and Java) separately.


Let’s take a look at this picture (click on the picture to enlarge it):

This is what we have. JSF-Code with an embedded Flex-Object. You can insert the firstname and the lastname with JSF-inputText -Fields, and the fields city and country with Flex. If you click submit, alle four values are saved inside the managed-bean.

Ok how is this possible? The solution is JavaScript! In some few words – if you enter some values for the city and country inside the Flash-Object, the ActionScript code is writing these values into JavaScript-Variables (which are declared in the JSF Code). If you hit submit, a JavaScript-Function is writing the values into the hidden tomahawk-inputFields which are bonded to the corresponding managed-bean (Page1Bean).

In ActionScript, you have to extend the class Proxy and overwrite flash_proxy function setProperty(..). You can see this here:

JSVariableProxy.as

Using Spring and Facelets together with NetBeans 6.1



In this blog you can read how to create a Web Application with NetBeans 6.1 and the GlassFish 2 Application Server. This Web Application is using Facelets, MyFaces 1.2 and the Spring 2 technologies.


Please note:
I have contributed this blog to the NetBeans Community.


Prerequisites

First update your NetBeans 6.1 to the newest version (currently it is Build 200804211638).

NetBeans Version 6.1 Build 200804211638

Install the Facelets Support Modules and restart NetBeans.


Create a new Web Application

Create a new Web Application, name it “Spring_and_Facelets“.

create a new Web Application

Choose GlassFish v2 as Server and click next.

choose GlassFish 2 as Server

In the last step, activate the Facelets-Framework.

choose the Facelets Framework

Open the Project Properties and remove all libraries.

remove libraries

Download and add my special MyFaces and Facelets Libraries Collection to the project.

special facelets and myfaces collection

Build and run the application. You should see this in your browser:

running facelets application


Adding some Facelets functionality

It is now time to add some specific Facelets functionality to this small Web Application. First we create a new facelets file, name it “header“.

create a new facelets file

the header.xhtml file

Insert this HTML code into the file:

Access the Spring-ApplicationContext from everywhere in your Application

Published by under Java,Spring



In this blog i will show you a short hint how you can access your Spring-ApplicationContext from everywhere in your Application.

Imagine you have an application (e.g. a web or swing-application) which you now want to be Spring-enabled. Ok you add the Spring libraries and the Configuration-file and create your Spring-beans. But there are still some old class-files which you can’t use in this way. These files still need access to the Spring-Honeypot where all the goodies exists and you don’t want to redesign your application.

First create the class “ApplicationContextProvider“. This class implements the ApplicationContextAware. A bean which implements the ApplicationContextAware-interface and is deployed into the context, will be called back on creation of the bean, using the interface’s setApplicationContext(…) method, and provided with a reference to the context, which may be stored for later interaction with the context.

ApplicationContextProvider.java

Contract First Web Services with Spring 2 and JAX-WS



This short blog entry will show you how easily you can integrate JAX-WS into a Spring 2 Project. The example sourcecode is depending on my previous blog How to modify JAX-WS SOAP-Messages and i am using NetBeans 6.1.


Prerequisites

Download the JAX-WS commons and XBean.


Transform the SOAP Web Services Project into a Spring Project

First open the Non-Spring-Project “How to modify JAX-WS SOAP-Messages“, switch to the project-properties and add the XBean, JAX-WS commons and Spring Framework 2.5 JAR-files.

add jar files to netbeans project


You can see in this picture which JAR-files have to be included in the project:

jar files in the netbeans project


Now you have to create the Spring Configuration file. Create the new XML-file: /WEB-INF/applicationContext.xml. If you are using NetBeans 6.1, navigate to File->New File->Spring Framework->Spring XML Configuration File.

create a new spring configuration file in netbeans 6.1


Replace the content with this:

Create CRUD-Mashups rapidly with Naked Objects and NetBeans

Published by under Hibernate,Java,NetBeans



In this blog i will show how easy and fast you can create Database-Mashups with full CRUD support, using Naked Objects.

Naked Objects is an open source Java-based application development platform which can use a transient (fake) or a real existing database. Support for Hibernate is included, so you can connect to every supported database.
Naked Objects also generates HTML and Window(DND) -Interfaces which are both
customizable.

Note:
Download-links to all files are available at the end of this blog-entry.


Prerequisites

Download the Naked Objects Framework http://www.nakedobjects.org/downloads/index.shtml and extract the included JAR-files from the directory “/lib“.

Naked Objects JAR files


Create the prototype

Create a new simple Java Application, name it “NakedObjectsDNDapp” and disable
the field “Create Main Class“. Naked Objects is using a specific class.

Naded Objects - create new java application


Open the project-properties and add the extracted JAR-files to the project.

Naked Objects - project properties


Switch to the category “run” and write in the field “Main Class“:
