Data Services Clients

Note that WSO2 EI is shipped with the following changes to what is mentioned in this documentation:

<PRODUCT_HOME>/repository/samples/ directory that includes all Data Integration samples is changed to <EI_HOME>/samples/data-services/.
<PRODUCT_HOME>/repository/samples/resources/ directory that includes all artifacts related to the Data Integration samples is changed to <EI_HOME>/samples/data-services/resources/.

This sample demonstrates how to use code-generated clients with data services. The service stubs are created using WSDL2Java tool.

Deploy the sample data services and start the server using the steps given in Samples Setup.

Open a command prompt and navigate to the <EI_HOME>/samples/data-services/clients directory.
Build the clients by executing the ant command as shown below:
```
ant
```
You can either run all the generic clients simultaneously or start an individual client.
- To start all the generic clients (e.g. rdbms, csv, excel, gspread, batch_request), run the ant command as shown below:
```
ant all
```
- To start a specific sample client, run the ant command with the client name. For example, to start the secure_sample client, run the following command:
```
ant secure_sample
```
  Listed below are the separate ant commands for each data service client.
  - 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 that 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.
