...
- (custom tabular datasource) implemented using the org.wso2.carbon.dataservices.core.custom.datasource.TabularDataBasedDS
...
...
- (custom query datasource) implemented using the org.wso2.carbon.dataservices.core.custom.datasource.CustomQueryBasedDS
...
- interface.
See how data services are created using custom datasources.
Building the sample
The sample data service InMemoryDSSample should be deployed using the instructions in Samples Setup section.
...
The sample service can be run using the TryIt tool, which is bundled with the WSO2 Data Services Server, or a code-generated java client sample as discussed in the Data Services Clients section.
Follow the steps below to demonstrate this functionality using the TryIt tool:
- Log in to the management console of your server and click List under Services in the navigator. The
CSVSampleServicewill - The InMemoryDSSample should be listed here.
- Click Try this service to open the TryIt tool for the InMemoryDSSample.
- Select the relevant operation and click Send to execute the command. The service contains the following operations:
- "addVehicle": This operation adds a new vehicle to the datasource.
- "getOldVehicles": This gives all the vehicles added with the year greater than 1970.
