Establishing a Connection

Creating a JDBC Data Source

You can create a JDBC data source to connect from your Java application, based on CData JDBC Driver for ADP.

Follow these steps:

Add the driver JAR file to the classpath. The JAR file is located in the installation directory's lib subfolder. Ensure that the .lic file is located in the same folder as the JAR file.
Provide the driver class. For example:
```
cdata.jdbc.adp.ADPDriver
```
Provide the JDBC URL. For example:
```
jdbc:adp:InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;SSLClientCert='c:\\cert.pfx';SSLClientCertPassword='admin@123'
```
Or, if there is a conflict in your application between drivers using the same URL format, use this form to ensure that you are using the CData driver:
```
jdbc:cdata:adp:InitiateOAuth=GETANDREFRESH;OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;SSLClientCert='c:\\cert.pfx';SSLClientCertPassword='admin@123'
```
Ensure that the URL starts with either jdbc:adp: or jdbc:cdata:adp:. The URL can include any of the connection properties in name-value pairs separated with semicolons.

Before configuring your connection, ensure you have obtained and formatted your SSL client certificate as described in Before You Connect.

To connect to ADP, set the following properties:

OAuthClientId: The client Id of the custom OAuth application you obtained from ADP.
OAuthClientSecret: The custom OAuth application's client secret.
SSLClientCert: The full file path to your SSL client certificate. If using a .pem file, ensure it contains both the Private Key and Public Certificate. If using a .pfx file, ensure it was created with the correct export password. See Before You Connect for more information.
SSLClientCertPassword: The password for the SSL client certificate, if applicable.
UseUAT: The driver makes requests to the production environment by default. If using a developer account, set UseUAT = true.
RowScanDepth: The maximum number of rows to scan for the custom fields columns available in the table (default=100). Setting a high value may decrease performance.
