openapi - Issue with Syncope 3.0.10 on WildFly – Failed to load API definition - Stack Overflow

I’m trying to install Apache Syncope 3.0.10 on WildFly using Maven. The build process completes successfully, and there are no errors in the WildFly logs. However, when I try to access the API endpoint, I encounter the following issue:

URL accessed: http://<server-ip>:8080/syncope/rest/openapi.json

Error message: Failed to load API definition – Fetch error: Not Found

What I’ve checked so far:

1. Deployment Status

   All WAR files (syncope.war, syncope-console.war, syncope-enduser.war, syncope-wa.war) are successfully deployed.

   No errors in server.log.

2. Configuration

   The core.properties file contains:

   server.servlet.contextPath=/syncope

   cxf.path=/rest

   WildFly is configured with a JNDI datasource for PostgreSQL, and database connectivity works fine.

3. Keymaster & Service Discovery

   keymaster.address is set to http://:8080/syncope/rest/keymaster

   Running curl -v http://:8080/syncope/rest/keymaster returns 404 NOT found.

4. Swagger & API Availability

   Swagger UI loads at http://:8080/syncope/, but the API definition is missing.

   There is no /WEB-INF/classes/rest/ directory in the deployed WAR file.

Questions:

Should the /rest endpoint be generated automatically, or do I need to configure something explicitly?
Is there a required dependency or configuration I might be missing for Syncope’s REST API to work on WildFly?
Has anyone successfully deployed Syncope 3.0.x on WildFly and encountered this issue?

Any guidance would be greatly appreciated!

What I Tried:

• Checked WildFly logs (server.log) – No critical errors or deployment failures.
• Verified database connectivity – PostgreSQL datasource is configured via JNDI in standalone.xml, and the connection test from WildFly CLI was successful.
• Verified configuration files (core.properties)
• Checked deployed WAR contents – The expected /WEB-INF/classes/rest/ directory is missing inside syncope.war.
• Swagger UI loads, but the API definition /syncope/rest/openapi.json is missing
