Integrating enterprise apps for data exchange is essential for every business
today, in order to ensure smooth flow of data across the organization. This sort
of data integration between various enterprise apps is a complex and
timconsuming process and is also not the same for every business environment.
Plus it also requires significant investments and resources. Microsoft’s
SharePoint and BizTalk Servers are some of the integration solutions that an
enterprise can opt for. But if you’re on a tight budget , then Jitterbit is an
excellent alternative.

Jitterbit is an Open Source alternative that provides quick, easy, and
affordable integration. It is a fully graphical integration solution that
provides users with a platform to create and share their integration projects.
Jitterbit can be used to integrate all major enterprise apps, databases,
flat-files, Web Services, and messaging systems like WSDL or JMS. It has been
optimized to function over Windows, Linux, or Solaris based OSs. With Jitterbit
an organization can integrate data between independent apps easily and quickly,
and also have a very low cost of ownership as compared to paid integration
solutions.

Direct Hit!

In the following article we will integrate data coming from a database that
will be converted to an XML format and will be posted on a location in the
shared file server. Doing so we will see how to configure the Jitterbit server
and its client.

Getting started
Jitterbit Integration suite can be availed from this month’s
PCQ_Professional DVD. It comprises of the following two components:

  • Jitterbit Integration Environment: It has an intuitive GUI that enables
    the user to configure, test, deploy, and even manage the integration projects
    on Jitterbit Server.
  • Jitterbit Integration Server: A scalable run-time engine that processes
    all operations for the integration projects. It uses a multi-threaded
    architecture so as to handle several transactions concurrently.

To install the Jitterbit server, extract the contents from the file
jitterbit-server-1.3.2.19-with-postgresql-win32.exe to a directory. In this
directory, run the setup.exe file which will initiate the Jitterbit server
installation wizard. During the setup process, the wizard will prompt for
installation of PostgreSQL server. If you already have PostgreSQL database
server installed you can skip this step, else you can have the wizard install it
for you.

Once installed, the wizard asks for credentials of database admin. You’ll
alos be asked to create the credentials for Jitterbit administrator. After the
wizard completes its job, we can ensure that the server is running by checking
that JitterbitTomcat and JitterbitProcessEngine processes are running through
the Task Manager.

We can install the client on the same system or on any other system on the
network. The Jitterbit Integration Environment can be installed through the
Jitterbit-client-1.3.2.5-win32.exe file on this month’s DVD. This file also
extracts the installation files into a directory and through the setup.exe file;
we can install the client interface of Jitterbit by following the wizard’s
steps.
With the client and server installed we can proceed with the integration of data
between disparate sources, but before that we must ensure that the database
server (PostgreSQL) is running. If it’s not, then it can be started from Start
Menu programs>PostgreSQL and then click on the Start Service option.

Starting Integration Project
Launch the Jitterbit Integration Environment, and from the options select
the Create New Integration Project and name the project as TestBuild. Then click
the Create button that will launch the main Integration environment screen. To
test the integration as we create it, we must connect to the Jitterbit
Integration Server. Clicking on the Login button on the main toolbar launches
the Login window. Enter the credentials that you mentioned during the
installation process. Upon successful connection to server, the user ID and the
server name appear on the top right corner of the interface. Since we are
getting data from a database and converting it to an XML file, we will define a
complete operation for which we will be having the source, target, as well as
transformation details.

For defining the target
parameters, we have to specify the shared file server path and its login
along with the name of file
To establish mapping between
source and target, select appropriate elements from both panes and click on
Map button

To create a new operation goto File > New > New Operation. In the operation
window give a name to the operation and from activity dropdown menu, select
Transformation. Now comes the part of defining the source. Click on the button
next to the Source file and from the pop-up menu select Create New. A new Source
window will open up. Give the name for this as MyDB and Type as database. For
connection parameters, select driver as PostgreSQL ANSI and enter the server
name or IP address for the PostgreSQL database (in our case it’s localhost as we
installed the client and server on the same machine). Now save the source
details and through Test connection button, we can test the source’s
connectivity to the database.

After defining the source, we need to define the target. Target defines where
you wish to put the information. In our case it’s going to be an XML file to be
saved on a shared file server. From the project tree, right-click on Target, and
select New Target as option from the pop-up menu. Fill the fields as shown in
the visual. Now comes the part of defining the transformation.

Transformation lets you map data from the source to a target format. In our
case it will be tables from the MyDB database that will be mapped to an XML
file. When you create a new transformation, a window opens where you have to
define the source and target formats and in following steps you have to map the
respective tables and their fields to the structure of the XML file. This XML
file formatting can be done by specifying a schema or dtd (document type
definition) file. For mapping the source fields to the target fields, select the
sources filed and then selecting its corresponding target filed. Clicking on the
Map button will establish the mapping relationship between them. Once the
mappings have been defined, Jitterbit tests transformations on-the-fly by
uploading sample data and running the test. To do this, click on Transformation
toolbar’s Toolkit button and select Test > Transformation.

Upon saving the transformation details, we can activate this operation by
first deploying the project on the server by clicking on the Deploy button on
the main toolbar and then clicking on the Activate button in the operation’s
toolbar the operation gets placed on the server’s queue for execution. Jitterbit
can similarly be used to source data from ERP apps and make that data available
in a standardized format for other applications to consume.
