Requirements

See Getting Started on how to jumpstart your development and grow as you go with SAP Cloud Application Programming Model (CAP). To learn about messaging in CAP, please consult the guide on Events & Messaging.

Setup

Install the plugin by adding it to the dependencies of your CAP Java project:

<!-- srv/pom.xml -->
<dependency>
  <groupId>com.sap.cds</groupId>
  <artifactId>cds-feature-advanced-event-mesh</artifactId>
  <version>${latest-version}</version>
</dependency>

The latest version can be found in the changelog or in the Maven Central Repository. The usage of CAP Java plugins is described in the CAP Java Documentation.

Then, set the kind of your messaging service to aem:

# srv/src/main/resources/application.yaml
cds:
  messaging.services:
  - name: "messaging-name"
    kind: "aem"

Setting Up the Broker

The broker itself must be created manually in SAP Integration Suite, advanced event mesh and trust must be established to the respective application in SAP Cloud Identity Services, both for the Solace broker and the SEMP API. For details, please consult SAP Integration Suite, advanced event mesh's documentation at help.pubsub.em.services.cloud.sap and help.sap.com.

Specifically, you need to configure SAP Integration Suite, advanced event mesh to allow your CAP application to connect to the broker. For this, follow guide CAP Plugin for SAP Integration Suite, Advanced Event Mesh.

Finally, the broker's credentials must be provided via a user-provided service instance with the name advanced-event-mesh and credentials in the following format:

{
  "authentication-service": {
    "tokenendpoint": "https://<ias host>/oauth2/token",
    "clientid": "<client id>",
    "clientsecret": "<client secret>"
  },
  "endpoints": {
    "advanced-event-mesh": {
      "uri": "https://<broker host>:<port>",
      "amqp_uri": "amqps://<broker host>:<port>"
    }
  },
  "vpn": "<vpn>"
}

To troubleshoot connection issues, set log level for component com.sap.cds.messaging to DEBUG. Check Operating CAP Java Applications → Observability for how to maintain log levels.

Broker Validation

Your app must be bound to an instance of service SAP Integration Suite, advanced event mesh with plan aem-validation-service. Please see Validation of VMR Provisioning for more information.
