What You Will Learn

After finishing this guide you will know which configurations can be made and which effect they have on the Workflow Executor App.

How to Configure the App

This window is used for editing all global settings of the Workflow Executor app.

Configuration Optionen Konfig
All changes made will be temporary and have to be submitted by clicking ‚Accept‘
Settings related to the engine should only be changed by more experienced users.
  • ‚Number of threads to run the engine‘: Defines how many cores the java process is allowed to use at max for the execution of the engine (max is 99).

  • ‚Time after which the engine queries whether it is still in the PAUSE state‘: When pausing a workflow, the engine will remain in the PAUSE-State. After that, the engine will repeatedly fetch for updates after the given polling time (which can be edited in ms here) was awaited.

  • ‚Activate expert mode‘: Whether the lite, or the expert mode should be used.

  • ‚Standard Workspace-Path‘: Used to edit the default location for new workspaces to be created in. Changing this will not transfer existing workspaces to that location! The default directory is: „C:\Users_USER_\.pak\workspaces“.
    Clicking the button next to the input field allows a selection of the standard workspace-path via a folder chooser.

  • ‚Do a data flow analysis before starting the engine?‘: The Workflow Executor also has the ability to run a Dataflow Analysis on new .bpmn files. When unchecking this, the engine will not run a Dataflow Analysis, but fail when the given .bpmn is corrupt.

  • ‚Enable editing of optional values after the Workflow is opened‘: Whether optional values can be edited after a Workflow is opened.

When changing settings, they will be adapted for every new installation of the Workflow Executor
  • ‚Automatic deletion of the Workflows‘: Used to edit the automatic deletion behaviour for previously ran Workflows. Possible options are:

    • ‚Never‘: Never delete previous Workflows

    • ‚At Restart‘: Delete previous Workflows on app restart

    • ‚After .. Days‘: Delete previous Workflows after the specified amount of days

  • ‚Fetch available adapters before creating new credentials‘: Whether there should be a search for available Connector Credentials before creating new Credentials in this dialog.

  • ‚Show deprecated Commands?‘: When selected, the single Command runner also shows all deprecated commands

  • ‚Activate full logging?‘: When selected, the app will provide more extensive logging in the log-files. However, as this option can blow-up the log file size by a lot, it’s reset at app restart

  • ‚Show text annotations in Bpmn?‘: When selected, text annotations that were set in the PAK-Editor will also be shown in the bpmn-viewer of the app

  • ‚Move the application to the foreground when any Human Task is encountered‘: When selected, the app will put in front of other running applications when an Human Task is encountered.

PAK has connectors and commands for Git. This means it has interfaces to directly communicate with Git and execute actions. Through these connectors, the software can automate Git commands such as retrieving changes or creating branches, enabling efficient integration and management of Git tasks.

Generic Human Tasks

PAK offers you a standard set of commands which require creative input from the user. Enables you to start with automating your workflows, that still need abit of human input.

Generic Commands

PAK offers a standard set of commands giving you the first steps to automate your workflows.

Nexus Maven Command Pool

Nexus is an artifact repository manager for storing binaries, libraries, and artifacts, supporting formats like Maven. Maven, a software project management tool, is based on the Project Object Model (POM) and allows developers to consistently define projects and dependencies. Our Command Pool offers commands for interactions between Maven and Nexus, such as artifact uploads or dependency retrieval.

Artifactory Maven Command Pool

Artifactory allows developers to store, retrieve, and manage binary files and artifacts, providing a
central source for all binaries used in a development process. Apache Maven is a software project
management and comprehension tool that enables developers to consistently describe a project and
its dependencies. Our Command Pool offers a collection of commands used to facilitate interactions
between Maven and Artifactory, such as uploading artifacts or retrieving dependencies.

Open API Command Interpreter

The OpenApi Command Interpreter allows you the automatic parsing of commands from an OpenApi defintion. No additional code needs to be written anymore, just add the address to the definition and our framework does the rest!

Kotlin Command Interpreter

The Kotlin Command Interpreter allows you the parsing and execution of commands within a Kotlin environment to automate various tasks or processes.

Bpmn Interpreter

Workflows come in many shapes and forms. The BPMN (Business Process Model and Notation) Interpreter enables the parsing of worklows defined in the BPMN format into the PAK intern model.

Human Task Interpreter

The Human Task Interpreter allows you the parsing and running of commands within a HTML and Javascript environment. Use this to build commands which need the creative input of a workflow user!

Java Command Interpreter

The Java Command Interpreter allows you the parsing and execution of commands within a Java
environment to automate various tasks or processes.


The heart of the PAK-Framework. Contains the means to run workflows with the PAK engine, but also the possibility to enrich the frameworks interfaces with your own implementations and solutions.
