It is possible to run
Java-generated applications in SAP Cloud Platform.
Before deployment, using a new environment in the Knowledge Base is recommended to generate a new deployment version that runs locally in the Tomcat of the computer used to work with GeneXus connected to the SAP HANA database, as described in How to use SAP HANA Database on SAP Business Technology Platform. In this way, you can make the configurations that will be used in the production database.
To make a deployment to SAP Cloud Platform, you need to have an account in SAP Cloud Platform because the information of the account will be used not only to connect to the SAP HANA database, but also to upload the application to SAP Cloud Platform during the deployment process.
