A Carbon datasource is a RDBMS or a custom datasource created using the Datasources sub menu of the Configuration menu in the management console. You can simply use that as the datasource of a data service. A Carbon datasource is persisted, and can be used whenever required. To create a Carbon datasource, see Adding datasources .
After creating a Carbon datasource, be sure to copy the JDBC driver to:
- <PRODUCT_HOME>/repository/components/lib directory
- <PRODUCT_HOME>/repository/components/dropins
For example, cp mysql-connector-java-5.XX-bin.jar /home/user/wso2ds/wso2-dataservices-XX/repository/components/lib.
Next, simply use that data source at the time a data service is created. That is, you must first follow the steps from 1 to 3 in creating a data service using various data sources. When you get to the Add New Data Source screen, select Carbon Data Source as the data source type. You get a drop-down list from which an existing Carbon data source can be selected as shown below.
To write a query to this datasource, see Writing Data Service Queries.
