Auxiliary materials for the laboratory:

• Activiti User Guide
• a book Activiti in Action

For the needs of today's classes you can deploy Activiti platform from the website: https://www.activiti.org/download-links (the lab is prepared for Activiti version 5) on the Apache Tomcat or JBoss Application Server. Then, you can launch the Activiti Explorer in your browser: http://localhost:8080/activiti-explorer, and then sign in to your account:

login: kermit
password: kermit

You can also use the temporary server version at our server: http://192.168.1.145:8080/activiti-explorer/ui/

When logged in, you should have noticed the top bar displaying the menu of 4 icons for administration of:

• Tasks - tasks,
• Processes - processes,
• Reports - reports,
• Manage - other issues, such as users, groups, database management, or process implementations.

In the Groups tab (Manage menu), look at the existing user groups. As an administrator user, we can use the default kermit user for a while, but we will need a non-admin user.

So, create a new user for you. Remember about a unique identifier! Assign your user to some groups but not the Admin group.

For better understanding of the BPM platform, we will create a very simplified model of the offer management process.

From the menu, select Processes. You should see 3 tabs:

1. My instances – to observe the existing instance of the process,
2. Deployed process definitions – to run processes deployed on the Activiti platform,
3. Model workspace – to create new models and deploy or edit existing process models.

In the Model workspace tab, click on the New Model button and create a new process model using the Activiti Modeler. Give your model a name and a description.

In the Activiti Modeler application window, set the process attributes (on the right side of the window). The key elements are: the process identifier ( Process identifier ) and the process name ( Name ), as using them we will be able to distinguish our process from other processes or processes of other users. Please also fill in the author's field ( Process author ).

By dragging from the left menu item Start event we will start modeling the target part of the process. At the beginning we model a very simplified process, as follows:

As in the case of the process, the same for BPMN elements on the right side we set the attributes.

• For Start event event: * Documentation : Start proceeding with an offer. * Initiator : initiator (this will hold the user who initiated the process) * Name : Offer received * Form properties - click on … and in a new window we set the following screenshot:
  * For task Specify offer : * Documentation : Please add available specification for an offer as attachments. * Assignments : we have 3 choices
  * assignee - assign a task to a specific user, * candidateUsers - assign a task so that any of the users can execute it, * candidateGroups - assign a task so that any user belonging to the assigned group can execute it.
  In our case, we only set the variable assignee to the value of $ {initiator} - this means that as the task performer, we indicate the person who started the process. In addition, for this task we set Form properties : * Specifications details Specification (specDetails) - The level of detail of the order specification (until we set it as a boolean), then we will want to convert that to enum (accurate, sufficient, insufficient). * Person responsible (id: responsible ) - person assigned to the formal analysis of the request (responsible for the analysis); Here you will assign that person and assign it to the variable.
