3. Introduction
The PlektonLabs EJB Connector is a useful tool when integrating Enterprise JavaBeans with MuleSoft.
This connector is reusable and cuts down the time required on development and testing by up to two-
thirds in most use cases. More importantly, it modernizes processes that rely on legacy systems,
allowing countless businesses out there to utilize cutting-edge technology at their own pace without
any disruptions.
This whitepaper aims to answer the following questions:
• What does this EJB Connector do and who is it meant for?
• What are Enterprise JavaBeans all about?
• How does the connector solve integration issues and connectivity problems?
• How could one go about using and implementing the EJB Connector?
As you read, you will be able to explore the contexts where the EJB connector can help businesses
circumvent integration challenges and market their developments in a much shorter time. In the long
run, this will go a long way in contributing to a business’s agility and overall growth.

4. An HVAC Player
and Their Business
Problem
In this day and age, all the innovations and improvements are passed through the gates of
technology. Whether there’s a problem with an organization’s existing operations and delivery
system, or it is simply looking for ways to innovate and get ahead of the competition, the
technologies that it can yield are the enablers of initiatives. If a business idea does not see the light
before the competitors, there is top-down pressure on IT and its capabilities.
Take this leading HVAC company, for example. When a device or unit needs repairs, the customer
of the HVAC enterprise in question typically contacts the company. They send someone over to
have a look and see what needs fixing.
While this may seem like a simple equation, it isn’t always so straightforward. What if someone’s AC
gives up on the hottest summer day? Or their water heater quits working during a snowstorm? It
takes quite a while for the repairs to be completed on top of the potential queue that customers may
have to deal with, and in the meantime, the client has to deal with a massive inconvenience.
The company could stay one step ahead of the whole
deal by building a home monitoring system that can
detect when a device is about to break down or reach
the end of its lifecycle. This won’t just alleviate the
customer’s headache and keep them ahead of the
curve when it comes to customer experienceーan
increase in customer service score allows for the
creation of new and diverse revenue opportunities.
This sets the stage for the problem at hand. While the
home monitoring system can collect information in the
form of alerts about the devices and store it in a
database, the information is still a long way from
being utilized. An intermediary telematics company
can compile the data into a more readable,
understandable format. The legacy CRM system,
which communicates the external world using EJB
services, contains various business logic to post an
alert, post site information, check the type of site, get
customer information, and so on, would then need to
be called upon to get the customer information and
forward it to a database. In turn, the database would
then be connected to a SAP BI to populate
dashboards with relevant customer information and
pain points.
So what will integrate everything together? For this,
the company needs a solid integration architecture.
The right tools that power innovation go a long way to
accelerate the time to market.

5. Fig 2.1 High-Level Solution Architecture
The client chose MuleSoft, a leading iPaaS, built for seamless customer
experience with API-led connectivity and automation. With MuleSoft, they
had created an architecture for the process, part of which the business
solutions diagram looks like this:

6. Innovation on the Fast Track
Now, this HVAC company doesn’t really need to deal with all that. But
proactively communicating with customers before their air conditioner goes
on a sabbatical is a huge step when it comes to innovation. It will draw in
new customers as the concept itself is a selling point. Older customers will
prefer getting a heads up before things go wrong and will be more likely to
stick with the company.
In addition, in a very competitive industry, other companies can swoop in
and innovate before you get a chance. So without constant innovative
initiatives, the business will lose its competitive edge and struggle to keep
up with growing market demands.
This also applies to businesses that rely on legacy software. Progress is
happening at lightning speed and the tendency to stick to older software can
cause a build-up of issues that can snowball into a massive problem. A gap
in connectivity brought on by an older system can result in a business that
needs extra resources and spends more time to make up for yesterday’s
technology.
Businesses that use older systems miss out on the opportunity to innovate
because their developments take a much longer time to market.
Take, for instance, the HVAC company. Developers spent ages trying to connect the
EJB-based CRM with MuleSoft using custom Java code as no shorter or quicker
workaround existed. On top of that, the codes aren’t easily reusable, meaning if some
other projects require similar integration, it requires copying the code and that leads to
duplication of codes. Moreover, if that project is run by a separate siloed team, which
happens in the majority of the cases, then the code is most likely rewritten and retested.
There is no room for wobbly tires on the fast track to IT success in an organization. This
means that the company will have to invest heavily in its IT and resources. But the issue
doesn’t end thereーwhat companies lose is precious time. Any kind of innovation or
development will take much longer to pull through, giving the competitors the chance to
slide ahead.
When it comes to saving time and accelerating innovation, accelerators like connectors
and frameworks provide organizations with a faster time to market. This is because they
serve as reusable building blocks for integration projects, allowing developers to bypass
the process of writing code, which takes up significant time and resources. As a result,
integration projects can be carried out at twice or even thrice the speed compared to
those done without accelerators. In addition, they offer documentation that makes the
application of use cases much faster, so they are helpful for handling sizable, enterprise-
wide issues.

7. The Lesser-Known Aspects of EJB
Enterprise JavaBeans are an older,
yet very popular server-side
software that can be known as a
subclass of Java EE. They reinforce
and manage aspects such as life-
cycle management, security,
transaction management, as well as
object pooling. They are best suited
for situations where a program
needs a remote connection. They
also come in handy when an
application comprises entirely of
business logic or requires a good
deal of scalability.
EJB applications generally require a
server like WebLogic or WildFly
(formerly JBoss). Enterprise
JavaBeans tend to come in 3 forms

Creating a good impact report means being
transparent with your audience. Back up
your claims with relevant data. Keep your
sentences concise when necessary, but
dive into detail when it comes to qualitative
and quantitative evidence. Remember: an
impact report is a combination of
understanding your mission, your work, and
your audience, and communicating that
clearly with the rest of the world.
Entity Beans
These beans store persistent data within
a data source. There are two variants
among entity beans:
Persistence is controlled by the
container: These entity beans assign
persistence to the EJB container.
Persistence is controlled by the entity
beans: These entity beans maintain their
own persistence.
Session Beans
There are two main kinds of session
beans:
Stateful: The stateful session Beans
store session information for each client
across several transactions. It remains
valid for a single client/server session.
Stateless: A stateless session bean is
managed by its container, so it can
accommodate many client requests.
1 Message-Driven Beans
These are the enterprise beans that
receive and manage Java message
service messages and are known as
message-driven beans.
They can only be accessed through
texting and lack any kind of interface.
Asynchronous communication takes
place between the queue and the
listener.
