Enterprise Service Bus(ESB)
Enterprise Service Bus (ESB) is an application that gives
access to other applications and services. Its main task is to
be the messaging and integration backbone of an enterprise.
An ESB is a distributed middleware system to integrate
different applications. All these applications communicate
through the ESB. It consists of a set of service containers
that integrate various types of applications. The containers
are interconnected with a reliable messaging bus.
MULE ESB
Mule ESB is a lightweight Java-based enterprise service bus
(ESB) and integration platform that allows developers to connect
applications together quickly and easily, enabling them to
efficiently exchange data.
WHY MULE ESB? 1.The Integration is possible with cloud
based applications also like
2.Reduces complexity compared to
WESB
3.Advanced Functionalities and
Features
The three main components of Mule Studio are as follows
Package Explorer:Package Explorer contains the entire
Structure of the project
Palette:Palette is a source for accessing
endpoints,components,transformers,cloud connectors
Canvas:It is a graphical editor to create your flows.

About Package Explorer
Src/main/app: stores your flow
Src/main/java:stores custom java class
Src/main/resources: creates graphical flow
and we can also add required resources
Src/test/java:contains the test related java files
Src/test/resources:contains the flow related test
files
Mapping:stores the mapping related files
Palette Components
Connectors send and receive data, and are responsible for
connecting to external resources and delivering messages.
connectors can be Inbound or Outbound. An Inbound
Endpoint receives messages via its associated transport. Each
transport implements its own Inbound Endpoint element. An
Outbound Endpoint sends messages via its associated transport.
Each transport implements its own Outbound Endpoint element
Transformers
Transformers convert message payloads to formats expected by
their destinations.
It performs different conversions depending on requirements.
Filters
Filters: Filters decide which Mule messages should be
processed. Filters specify the conditions that must be met for a
message to be routed to a service or continue progressing
through a flow. There are several standard filters that come with
Mule ESB, which you can use, or you can create your own filters
Scenario-1
Pick a Order XML file from ftp server and
place the file into JMS Queue in string
format and take the file from the same
queue and place into
local folder(JSON format).
Scenario-2
Send a request (Order Request) to web
service through http endpoint and
place the response(Order Info) in local
folder in the form of csv file and do
transformation using data mapper.
Scenario-3
Using Quartz scheduler invoke mule flow
every 30 sec (Invoke web service and
place the response in local file).
Scenario-4
Can you send an email if got an
exception in mule flow.
THANK YOU
ANY QUERIES?
