BEFORE YOU BEGIN

Prerequisites.

FlowCentral Convergence runs on any modern Java runtime. Make sure the following is installed on your machine before proceeding.

Java JRE with JDK

A Java Development Kit (JDK) that includes the Java Runtime Environment (JRE). Any vendor - Oracle, Adoptium, Amazon Corretto, Azul Zulu - is supported.

Minimum version 1.8 (Java 8)

Supported OS

Windows or Linux. The JAR is platform-agnostic - as long as Java runs, FlowCentral Convergence runs.

Verify install java -version

Free Port

By default FlowCentral Convergence binds to port 8080. Make sure it is available, or change it in application.properties.

Default URL http://localhost:8080
THE FLOW

Six steps. That's it.

Follow the sequence below. Each step builds on the last — by step six you'll be logged into the Convergence Studio.

  1. 1

    Install Java (JRE with JDK)

    Install a Java Development Kit that includes the runtime. The minimum supported version is Java 1.8. After installation, open a terminal and confirm with: 

    java -version

    Skip this step if you already have a suitable Java version installed.

  2. 2

    Download the Developer Edition

    Grab the archive for your operating system from the Downloads page.

  3. 3

    Extract the archive

    Extract the downloaded file into a suitable working folder. You should see flowcentral-convergence.jar and an application.properties file at the root.

  4. 4

    Navigate into the extracted folder

    Open a command prompt or terminal and cd into the folder where you extracted the archive. 

    cd path/to/flowcentral-convergence-developer-2026.0.1
  5. 5

    (Optional) Configure database and port

    Open application.properties in any text editor. If you leave it untouched, Convergence starts with an in-memory HSQLDB on port 8080 — perfect for evaluation. See the Configuration section for details.

  6. 6

    Start Convergence

    Launch the platform from the command line: 

    java -jar flowcentral-convergence.jar

    Wait for the server to finish starting - you'll see a log line confirming the port is bound. Then open your browser and navigate to: 

    http://localhost:8080

    Log in with the default credentials:

    UsernameSYSTEM
    Passwordsystem
CONFIGURATION

Optional: tune application.properties.

Out of the box, Convergence runs with an in-memory HSQLDB on port 8080 - no setup required. When you're ready to point at a real database or change the port, edit the properties file below.

application.properties Edit and restart instance 
# Server
(uncomment to use)
#jetty-embeddedwebserver.httpPort=8080

# PostgreSQL example (uncomment to use)
#application-datasource.dialect=postgresql-dialect
#application-datasource.connectionUrl=jdbc:postgresql://localhost:5432/convergencedb
#application-datasource.appSchema=public
#application-datasource.username=app
#application-datasource.password=s3cr3t
TROUBLESHOOTING

Frequently asked questions.

Stuck on a step? Most issues come down to Java version, port conflicts, or file permissions. Check the answers below first.

Which Java version do I need?

Java 1.8 (Java 8) or later. Any vendor is supported - Oracle JDK, Adoptium (Temurin), Amazon Corretto, Azul Zulu, Microsoft OpenJDK. Run java -version to verify.

Do I have to install a database?

No. Out of the box, FlowCentral Convergence uses an in-memory HSQLDB — nothing to install, nothing to configure. When you're ready, you can point it at PostgreSQL, SQL Server, Oracle, MySQL or MariaDB by editing application.properties.
NOTE: The in-memory database is non-persistent; all records are lost when the instance is stopped..

Port 8080 is already in use. What do I do?

Open application.properties the uncomment and change jetty-embeddedwebserver.httpPort to any free port (for example 8081). Restart the JAR.

Can I run this on Linux without a GUI?

Yes. FlowCentral Convergence is a headless server - no GUI required on the host. You access the instance from any browser on any machine that can reach the server.

How do I stop the server?

Press Ctrl + C in the terminal where the JAR is running. The server shuts down cleanly.

What are the default login credentials?

Username: SYSTEM - Password: system. Change these immediately if you're exposing the server beyond localhost.
