Data Services Clients

Introduction

This sample demonstrates the usage of code-generated clients when used with data services. The service stubs are created using WSDL2Java tool.

Building the sample

Deploy the sample data services using the steps given in   Deploying Samples .

Executing the sample

There are separate ant tasks for all the samples as follows.

• rdbms - RDBMS data source based data service clients.
• csv - CSV data source based data service client.
• excel - Excel data source based data service client.
• gspread - Google Spreadsheet data source based data service client.
• batch_request - Represents a data service client which executes a batch request in a data service.
• secure_sample - Represents a data service client where a security enabled data service is called. The data service security is enabled manually by the usage of a "services.xml" file in conjunction with the data service.
• file_service_app - Represents a standalone Java application which uses REST style invocations to transfer binary data. This also demonstrates the usage of streaming data, where a file of any size can be uploaded or downloaded using the application.

Follow the steps below to run the clients:

1. Switch to data service clients sample directory.

    e.g. # cd CARBON_HOME/samples/clients

2. Running all the generic clients (rdbms, csv, excel, gspread, batch_request)

    # ant

3. Run the secure sample sample client

    # ant batch_request

4. Running the file service application sample client

   # ant file_service_app
