This document provides an overview of Mule Studio and how to create a basic Mule application. It discusses: - Launching Mule Studio and creating a new project - The key sections of the Mule Studio workspace like the Package Explorer, Outline, Console, and Palette - Dragging common elements like the HTTP Endpoint, Java Component, and Append transformer from the Palette onto the Canvas - Configuring the Java component to use a sample Java class to append a string - Noting that some may need to change the HTTP Endpoint port if 8081 is already in use

4. • Note that a flow must have a message source, to provide message
contents. Subsequently, a Mule message will get passed from its
message source and through other message processors (mention
this while the animation of messages and message processors
plays).
• Note that while a message source is often an inbound endpoint for a
transport, this is not necessarily so. Instead, a message source can
be a reference by a flow ref in a superflow, etc. In the case of a
flow ref, the referenced flow can begin with any message processor.
• Similarly, an outbound endpoint for a transport can end a flow – but
for a subflow, this is not necessary – the message will be passed to
the next message processor following a reference to this flow in its
superflow. Typically, a flow with an outbound endpoint has a
corresponding inbound endpoint as its message source.

5. Note as needed that the payload shown here contains XML
representing an order and including an order id (<id>, here a truncated
UUID), a customer id (<custId>, also a truncated UUID), and a total for
line items in the order. The line items or other information would follow,
where the ellipse is placed.

11. • Basic use case involves:
• user inputs price request, with origin (e.g. SFO) and
destination (e.g. JFK) pair
• airline service outputs price if origin/destination pair is served,
error message otherwise
• in first lab, only one airline
• for subsequent labs, many airlines, and aggregation of price
information in message
• possibly different types of integration for different airlines
• airlines modeled in Mule just for lab
• NB: labs are progressive! So please make sure to finish with a
working lab, and don’t hesitate to ask for help.

13. • All boxes are Message Processors (MPs)
• Endpoints are special type of message processor

16. 7-
CLICK > LAUNCH ARROW AND MULE STUDIO
APPLICATION LOGO
DOUBLE CLICK ON THE MULE STUDIO ICON .
THIS WILL LAUNCH THE MULE STUDIO
APPLICATION.
CLICK> WORKSPACE SCREEN LAUNCH WITH
HIGHLIGHT BOX
AFTER THIS “WORKSPACE” CONFIGURATION
TOOL WILL LAUNCH. THIS IS USED TO

17. 7-
CLICK > HIGHLIGHT BOX AROUND “NEW PROJECT ”
Create your new project.
CLICK > ARROW WITH LAUNCH OF THE “NEW MULE PROJECT”
WINDOW.
Name it whatever you would like, perhaps CloudHubProject1

18. 7-
MULE STUDIO WORK BENCH IS LAUNCHED.
KEY SECTIONS OF Studio THAT WILL USED TODAY ARE “PACKAGE
EXPLORER”, “OUTLINE”, “THE CONSOLE AREA”, “PALETTE” AND
“THE CANVAS”.
CLICK > HIGHLIGHT BOX AROUND “PACKAGE EXPLORER”
You'll see all your files here it he project. Displays project folders and
files in a tree format
CLICK > ARROW AND HIGHLIGHT BOX AROUND “CONSOLE
AREA”
The console area will highlight problems in this view, other views will
show you the running status and log of you application
CLICK > ARROW AND HIGHLIGHT BOX AROUND “PALETTE”
The palette is where all of our standard elements can be dragged from

19. 7-
Take a moment and find this on your screen
You’ll see three elements

20. Note re Animations:
• Text sections and workflow diagram boxes appear together, as
instructor clicks (first click for Model, second click for Configure, etc.)

21. • Note that project files can be copied by dragging and dropping, or
imported using File > Import

22. Easy way to find HTTP is to type HTTP into the filter Box
Drag the HTTP Endpoint Onto the Canvas
The Defaults for the HTTP Endpoint are OK
22

23. Make sure to select the Java component not the Java transformer…
These are different elements.
Type Java into the Filter Box
23

24. • Note that the … button can be used to browse packages to select
the class
24

25. Easy way is again to type append into the Filter box

27. Notes to Trainer
1) Some participants have things/firewalls/applications already running
on their computer on port 8081, they may need to change the port of
their HTTP Endpoint
2) Let THEM figure out how to use the application by pointing them
towards the Java Component, do not just tell them the answer, we
need to immediately establish a precedent for them thinking instead
of asking questions
