Action Script or JavaScript: A Comparison
A comparison between Action Script and JavaScript, and when to use what.
Development Process
This best practices chapter provides guidance on how to best navigate the development process in Scheer PAS so that you can work efficiently and securely. Together, these guides help you structure your work from first test runs to go-live, ensuring that services are not only implemented, but delivered reliably.
-
Developing with Designer Test Environment
This article describes the change in the development process that comes with PAS 23.1, where development and deployment have been decoupled to speed-up development.
-
Going Live with a Designer Service
This article describes the procedure to go live with a Designer service from a test system to a productive system.
-
Solving Transport-Related Problems
Sometimes it is necessary to transport a service from one system to another. If one of the points explained on this page applies to your service, you must take action.
-
Common Development Challenges
This best practice chapter focuses on solving specific problems during development. Each topic addresses a common challenge and shows you how to resolve it efficiently, so you can keep your project moving without getting stuck in the details.
-
Synchronous and Asynchronous Service Communication via REST
In some cases, services need to exchange data with each other. This exchange can be either synchronous or asynchronous and can be implemented in both cases via the REST interfaces of services.
-
Accessing Data From BPMN Process Instances From the Outside
In a Designer service, you can access data from BPMN process instances from the outside, e.g. from another Designer service. This article describes how you can do this using either the xUML Runtime API or the xUML service API.
Service Operation
If you are wondering how to use your services productively and manage their lifecycle, you will find answers in this best practice chapter. Together, these guidelines help you keep services stable, transparent, and adaptable throughout their entire lifecycle.
-
Changing the Database for Persistent States
By default, the database that stores all persistent states for the BPMN process is a SQLite database that resides in the xUML service container itself. This article describes how you can use any other supported RDBMS system.
-
Exposing Designer Services via API Management
This article describes how you can make services, that have been deployed from the Designer, available to others. You can publish them via Scheer PAS API Management and restrict their usage with additional policies.
