Red Hat JBoss Fuse - Getting Started Home Loan Demo version 6.2 Part 2

This is the 2nd 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, we will focus on playing with the integration framework in JBoss Fuse, which base on the open source project Apache Camel. And in the last video of the series I will deploy the integration projects onto the OSGi container and manage it with Fuse Fabric. You can find the post about receiving data here : Part one

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.

And for this part of the demo,  we are going to concentrate on processing the customer data, by reading the xml file and store it into a Postgres Database. There are many components in JBoss Fuse that you can choose to interact with DB. This demo uses the most simple and straight forward sql component, just like a normal sql insert in your java program, but less coding needed. The new SQL component in JBoss Fuse 6.2 can now take in dynamic variables through simple expression in sql queries, as before we need to set the data in header.  We are also going to take a look at the latest Data mapping tools, mapping data from xml to Java POJO.

Watch the video for complete instructions,


In second part of demo,  you will learn

Endpoint reading from activemq messaging broker
The ActiveMQ component allows messages to be sent to a JMS Queue or Topic; or messages to be consumed from a JMS Queue or Topic using Apache ActiveMQ.

  <bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
      <property name="brokerURL" value="tcp://localhost:61616"/>
      <property name="userName" value="admin"/>
      <property name="password" value="admin"/>

  </bean>

Data Mapping tools with JAXB transformation
Translate one data format(XML) into another(Pojo) using JAXB

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>

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 …

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.

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 …
