Red Hat JBoss Fuse - Getting Started Home Loan Demo version 6.2 Part 4

This is the 4th part of my getting started demo for JBoss FUSE 6.2, an update from my old demo project.  For people that are getting started to know Fuse, and wants to get their hands dirty and develop a JBoss Fuse project.

There is a series of blogs/videos, you can find the previous post here:

The story behind the home loan demo is to prepare housing appraisals base on the content given real estate vendor. The appraisal needs to talk to local database, external google map API and also provide information through a web Restful API. We have divided this project into 4 independent integration applications, deploy in a distrusted environment, each handle single functions, and using message broker as the asynchronous medium to pass the message and data around.

First part of demo was to take in and process the information, first we separates the 2 kinds of files, because they are handled differently. And send it to separate messaging broker.
Second demo was about processing the customer data, by reading the xml file and store it into a existing database table.
Third part starts to process housing data by getting number of schools surrounding the house address via SAAS.

Since we have the surrounding schools, we can now start to appraise the value of the house by the information provided, such as number of rooms, number of bathrooms, and even the size of the property. This business rule is built in a Java POJO, by calling the POJO with the data, it then calculate the actual value and store it into Database.


Here is the video,


In this demo,  you will learn

SQL Endpoint 
The sql component allows you to work with databases using JDBC queries. Also setting datasource for the sql component

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
  <property name="driverClassName" value="org.h2.Driver"/>
  <property name="url" value="jdbc:h2:file:~/h2/homeloan;AUTO_SERVER=TRUE"/>
  <property name="username" value="sa"/>
  <property name="password" value=""/>
</bean>
 
<!-- configure the Camel SQL component to use the JDBC data source -->
<bean id="sql" class="org.apache.camel.component.sql.SqlComponent">
  <property name="dataSource" ref="dataSource"/>

</bean>

Properties Place holder
Placing data into properties, to set base on different configurations.
  <propertyPlaceholder location="classpath:sql.properties,googleapp.properties" id="properties"/>

Reference Java POJO bean in camel context
<bean id="Appraiser" class="org.blogdemo.homeloan.processor.AppraisalProcessor" />

Hi Chritina,

Part three of the home demo is also included in this part?

Thanks,

Hi Christina,

The Data Transformation component automaticaly created a package named "homeloanhouse" under the src/main/java folder where the JAXB classes where generated.
Is it possible to specify another name for the package? Can I previouly define any specific namespace in the XSD file so it's used for the jaxb classpackage or do I have to do it manually editing the blueprint file and changing the name of the package?

Thanks,
Samuel Lima

Yes, you can, but then you will need to look at the endpoint of dozer and make sure it is pointed to the right package.

Fuse Integration Service - Setup JBDS and create first quickstart application

Before we go and start creating our first application, I want to show you how to setup your JBoss Developer Studio, create a small application from the quickstart example and then running it on Fuse Integration Service.

I am using JBoss Developer Studio version 9, you can find it here.
After download the

double-click it, and start installing with default values.

After successful installation, we will need install the plugins for Fuse, on JBoss Central view, select software update, select enable early access.


And select JBoss Fuse Development for the plugin,


Click on install, and we are all set to go!

First thing first, we want to create a Fuse project to deploy on the base of Fuse Integration Service, which is OpenShift. If you have not installed it, please go back to my previous post for instructions. So on your JBDS, right click and start creating the project. Select new, maven project, if you have installed the plugin correctly, you should …

RHTE - Supercharge your integration services

Red Hat Tech Exchange has taken place in Vietnam, Ho Chi Minh city two weeks ago, it is a great event held by Red Hat in Asia Pacific Region.

I am very fortunate to talk in this great event, to talk about the things I have been working on and even discuss it with many. Also got lots of great ideas too. So here are the slide.

My first talk was with Thomas Qvarnström about how to handle large size data in JBoss Fuse and how JBoss Data Grid can help in the situation.

Here is the agenda of the talk, we will be talk about this in the up coming webinar on 24th Sept.

Integration often involves storing, retrieving, and transforming data. Using a traditional database in your integration is likely to becomes a bottleneck that is expensive and hard to …

Red Hat JBoss Fuse/A-MQ - Fuse and A-MQ Version 6.3 GA is released!

Fuse and A-MQ 6.3 GA has just went out. Maybe, you would think this is just only a minor version release why should I care? Hold your thoughts on that! Because they have done a lot of improvements and also added many new features into this release.

Besides various bug fixes and making sure Fuse Fabric is much more stable. There are two major change in this version update:

New Tooling in JBoss Developer Studio (JBDS) 9.1 GA. Newer Apache Camel version – Camel v2.17. I was really impressed by the work put in to make developing Camel application much simpler. First is the installation of tooling itself. Now it has a all-in-one installer so you don't need to worry about which plugins you need to check. See the videos below to see the new "Getting Started" of Fuse 6.3.



And If you notice from the above video, the presentation of camel route in JBDS has also updated. It fixed some of the miss representation of logic and making it easier to read.

Old Camel Route
New Camel Route
