PrintStackTrace(); } return aDataVector; } The getRows() method accepts an SQL ResultSet object and returns a vector. It loops through the ResultSet object. Each row of the ResultSet object is converted into an array of strings. The array of strings is added to the vector. JDBCPoolCatalog class Next, we look at the JDBCPoolCatalog class. We start with import statements to match those required for the DataSource support as shown in Example 2-22. *; public class JDBCPoolCatalog extends JDBCCatalogSupport { private String connUserId = null; private String connUserPassword = null; private Context v3Ctx = null; private DataSource v3DS = null; We use the connectToDB() method, shown in Example 2-23, to get the JDBC connection.

GetRows() method Only one JDBCCatalogSupport method is relevant for the JDBCItemCatalog class. The getRows() method is shown in Example 2-3. toString(); // price Item Information the vector Chapter 2. } return aDataVector; } To make our code more generic in nature, we use vectors to pass information. The getRows() method accepts an SQL ResultSet object and returns a vector. It loops through the ResultSet object. Each row of the ResultSet object is converted into an array of strings. The array of strings is added to the vector.
