Abstract

This document describes how to integrate Red Hat CodeReady Studio with Red Hat Process Automation Manager.

Preface

As a developer, you can integrate Red Hat CodeReady Studio with Red Hat Process Automation Manager to write complex applications and leverage code auto-completion.

Chapter 1. Installing Red Hat CodeReady Studio

Red Hat CodeReady Studio is an integrated development environment (IDE) based on Eclipse. It integrates tooling and run time components by combining Eclipse, Eclipse Tooling, and Red Hat JBoss Enterprise Application Platform. Red Hat CodeReady Studio provides plug-ins with tools and interfaces for Red Hat Process Automation Manager.

Procedure

  1. Download Red Hat CodeReady Studio:

    1. Log in to the Red Hat Customer Portal.
    2. Click DOWNLOADS at the top of the page.
    3. On the Product Downloads page, navigate to the JBOSS DEVELOPMENT AND MANAGEMENT section, and click Red Hat Developer Studio.
    4. On the Software Downloads page, download Red Hat CodeReady Studio 12.13.0 Stand-alone Installer (devstudio-12.13.0.GA-installer-standalone.jar).

  2. In a terminal window, navigate to the directory where you downloaded the installer JAR file and enter the following command: 

    java -jar devstudio-12.13.0.GA-installer-standalone.jar

  3. Follow the instructions in the installer to complete the installation.

    For more information, see the Red Hat CodeReady Studio Installation Guide.

Important

Because of an issue in the way multi-byte rule names are handled, you must ensure that the instance of Red Hat CodeReady Studio is started with the file encoding set to UTF-8. You can do this by editing the $DS_HOME/studio/codereadystudio.ini file and adding the following property: "-Dfile.encoding=UTF-8".

Chapter 2. Installing Red Hat CodeReady Studio plug-ins
