Creating a JDBC Data Source

You can create a JDBC data source to connect from your Java application. Creating a JDBC data source based on the CData JDBC Driver for Couchbase consists of three basic steps:

• Add the driver JAR file to the classpath. The JAR file is located in the lib subfolder of the installation directory. Note that the .lic file must be located in the same folder as the JAR file.
• Provide the driver class. For example:
  

  cdata.jdbc.couchbase.CouchbaseDriver

• Provide the JDBC URL. For example:
  

  jdbc:couchbase:User='myusername';Password='mypassword';Server='http://couchbase40'
  
  or
  
  jdbc:cdata:couchbase:User='myusername';Password='mypassword';Server='http://couchbase40'

  The second format above can be used whenever there is a conflict in your application between drivers using the same URL format to ensure you are using the CData driver. The URL must start with either "jdbc:couchbase:" or "jdbc:cdata:couchbase:" and can include any of the connection properties in name-value pairs separated with semicolons.

Connecting to Couchbase

To connect to data, set the Server property to the hostname or IP address of the Couchbase server(s) you are authenticating to.

If your Couchbase server is configured to use SSL, you can enable it either by using an https URL for Server (like https://couchbase.server), or by setting the UseSSL property to True.

Couchbase Analytics

By default, the driver connects to the N1QL Query service. In order to connect to the Couchbase Analytics service, you will also need to set the CouchbaseService property to Analytics.

Couchbase Cloud

Set the following to connect to Couchbase Cloud:

• AuthScheme: Set this to Basic.
• ConnectionMode: Set this to Cloud.
• DNSServer: Set this to a DNS server. In most cases, this should be a public DNS service like 1.1.1.1 or 8.8.8.8.
• SSLServerCert: Set this to the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected. Alternatively, set "*" to accept all certificates.

Authenticating to Couchbase

The driver supports several forms of authentication. Couchbase Cloud only accepts Standard authentication, while Couchbase Server accepts Standard authentication, client certificates, and credentials files.

Standard Authentication

To authenticate with standard authentication, set the following:

• AuthScheme: Set this to Basic.
• User: The user authenticating to Couchbase.
• Password: The password of the user authenticating to Couchbase.

Client Certificates

The driver supports authenticating with client certificates when SSL is enabled. To use client certificate authentication, set the following properties:

• AuthScheme: Set this to SSLCertificate.
• SSLClientCertType: The type of client certificate set within SSLClientCert.
• SSLClientCert: The client certificate in the format given by SSLClientCertType.
• SSLClientCertPassword (optional): The password of the client certificate, if it is encrypted.
• SSLClientCertSubject (optional): The subject of the client certificate, which, by default, is the first certificate found in the store. This is required if more than one certificate is available in the certificate store.

Credentials File

You can also authenticate using using a credentials file containing multiple logins. This is included for legacy use and is not recommended when connecting to a Couchbase Server that supports role-based authentication.

• AuthScheme: Set this to CredentialsFile.
• CredentialsFile: The path to the credentials file. Refer to Couchbase's documentation for more information on the format of this file.
