Method Description

getConnectionSpec() Used to get the ConnectionSpec object if it is already

specified in the getConnection method. If it is not
specified, this method returns a newly created Con-
nectionSpec instance.

supportsCapability(ConnectionCapability) Used to find the connection capabilities of the DME.

Returns true if the specified capability is supported.

Table 9-3 javax.datamining.resource.ConnectionSpec interface

Method Description

set/getURI(String) Used to set and get the location of the DME with which the API will

interact.

set/getUsername(String) Used to set and get the user name used to connect to the DME.

set/getPassword(String) Used to set and get the password used to connect to the DME.

set/getLocale(Locale) Used to get the locale information of the client so that the DME can use

language-specific settings and error messages.

Listing 9-3 Get the Connection using ConnectionSpec

1. //If getConnection(ConnectionSpec) supported by the DME
2. if(connFactory.supportsCapability(ConnectionCapability.connectionSpec)) {
3. //Get the empty connection spec from the factory
4. ConnectionSpec connSpec = connFactory.getConnectionSpec();
5. //Specify the connection details
6. connSpec.setURI("DMELocation");
7. connSpec.setUsername("user");
8. connSpec.setPassword("passwd");
9. //Get the DME Connection
10. Connection dmeConn = connFactory.getConnection(connSpec);
11. }

9.1.2 Using the Connection Interface

The JDM resource.Connection interface provides methods to create
and manage mining objects, execute mining tasks, and explore the
capabilities of the DME. Table 9-4 lists all the methods in the
Connection interface. In this table, the Connection interface methods
