This document provides an overview of creating a basic BPMN workflow process in WSO2 BPS 3.5. It includes instructions on installing WSO2 BPS, creating a new BPMN project in Eclipse using the Activiti plugin, designing a simple "Open Bank Account" process with steps like data entry forms, decision points, and human tasks, deploying the process to WSO2 BPS, and accessing the running process via REST APIs. The goal is to demonstrate the basic BPMN capabilities of WSO2 BPS like designing, deploying and executing BPMN 2.0 processes.

1. WSO2 BPS 3.5
Partner Foundations Workshop
BPMN Chapter
Edgar Silva @jedgarsilva

2. Foundation
o WSO2 BPS 3.5 - BPMN Capabilities
o Summary:
o Rely on Apache project: Activiti BPMN
o Historical background:
o Tom Bayens (former jBPM founder/leader)
o Supported as well for other organzations
o Activiti on Steroids
o Multitenant
o Clustering
o Rich REST API
o etc

3. Installation
o As easy as any WSO2 Product
o Download
o Unzip
o Run (BPS_UNZIPED_FOLDER/bin/wso2server.sh)

6. Deployed applications
o Carbon (Management Console)
o Human Task Explorer
o BPMN Explorer

12. Creating your first workflow process

13. Before your start
o You must have the latest
Activiti Plugin installed into
your eclipse:
o http://activiti.org/designer/update/

14. Take a look on what we will do ….

16. A customer want to open a bank account
Fulfil
data
(Form)
check initial deposit
> amount X
Notify customer

17. Process Explanation
(When process is well designed, that is useless)
o A customer want to open an account into our thin bank
o According the initial process, that customer will be
managed by a different customer level (platinum or
standard).
o In the end the customer will discover who is your account
manager, that will be the responsible for the whole
relationship
o That last step/interaction will be made via e-mail

18. Create a new project
1. Create an Activiti Project
called thinbank-bpm
2. Follow the basic
instructions for creating
the project (source
destination, package etc)
3. Create an Activiti Diagram
called open-
account.bpmn
18

19. Configuring Process default metadata
o Please click on the
diagram and set
the properties
according the
image on this slide.
19

20. Start Node
o That is the first step in the process.
o From the Palette, just add that start
node
o Click on the start node and set the
following properties
20

21. Start Node
o Now Click on the Form tab and add the following properties accordingly:
21

22. Checkpoint 1 : What had you made so far…
o You configured which will be the initial variables
available for instantiate a new process instance.
o Those variables will be presented into a form, that
can be rendered in WSO2 BPS 3.5.x

23. Basics : Process Instance
o Class vs Object
o Definition vs Instance
23
Process Definition
Process Instances

name: Elvis Presley
name: Mano Brown

24. Creating Sequence Flows
o Between each step in the
process, you will need a
sequence-flow (arrow)
representing the flow.
o It might be added from the
components palette
o or:
24

25. Creating Sequence Flows
o In the next step we will create
an exclusive gateway node.
o So click on exclusive and drag
to your right in the canvas.
25

26. Creating Exclusive Gateway
o Please add the
following properties
26

27. Creating Exclusive Gateway
o Please add the
following properties
27

28. Creating Exclusive Gateway
o An exclusive gateway defines the possible
next steps, according some variable or event.
o It is similar to a Case or IF according to the
scenarios
o In our sample, we will have 2 possible ways:
o A Human Task for Default Account
or
o If the Initial Deposit Amount is larger
than <A value> it goes to Premium
Account
o In that case we will 2 possible next steps
according a variable
28

29. Creating the Default Account Human Task
o Please fill the following
properties:
o Name: Default Account
o Click on Main Config tab and
add the following value on
Candidate Group: “default-
managers"
o Click on Form Tab and add the
the properties according next
slide

30. Add the following Form Properties
o Note: Just take a look on properties that are writable or not (read only
props), that ones were informed by the “customer" in previous step.

31. Now: Creating the Premium Account Human Task
o Name: Premium Account
o Candidate Group: premium-managers
o Here the form:

32. From Exclusive Gateway, how the process knows to where
navigate?
o One of the sequence-
flows will be the default
one.
o And the other will be
activated/executed when
and just when the
(condition) variable
initialDeposit is greater
than 10,000

33. From Exclusive Gateway, how the process knows to where
navigate?
o One of the sequence-flows
will be the default one.
o And the other will be
activated/executed when
and just when the
(condition) variable
initialDeposit is greater
than 10,000

34. From Exclusive Gateway, how the process knows to where
navigate?
o In that sequence flow that
lands on Premium Account
Human Task, you will add
in the Main config tab the
following condition:
${initialDeposit>10000}
o So based on the value on
the initialDeposit process
instance variable, we will
go to Premium or Default
Account.

35. Email Task
o The step before
finish that process
sample is to send
and email to the
customer.

36. Email Task
o The step before finish that
process sample is to send
and email to the customer.
o Keep in mind that you have
to configure BPS for
sending e-mails: https://
docs.wso2.com/display/
BPS351/Working+with+the
+Email+Task

37. Finish : End Node

38. Deploying Process

39. Exporting Process to an Archive (zip)
o It will generate a zip
file.
o After that rename
the file for .bar

40. Deploying Process in BPS Console

46. Process Instance

47. BPMN REST api

48. Accessing the whole process context via REST
Testing via Postman
https://192.168.1.135:9443/bpmn/runtime/process-instances
https://<SEU IP>:<PORTA>/bpmn/runtime/process-instances

49. Accessing the whole process context via REST
