Getting Startedwith pureQuery

Chapter 11 – Annotated-Method Programming Style 237
and you add or change something in your interface, you need to rebind your interface
before you can run methods in it again.
You can specify pureQuery properties either in a properties file, in a
java.util.Properties object that you pass to a DataFactory.getData method, or
as the value of the IBM Data Server Driver for JDBC and SQLJ property pdqProperties.
Refer to the IBM Optim pureQuery Runtime documentation for details about specifying
pureQuery properties.
One common way to specify a properties file is to provide a file named pdq.properties.
If your application creates a connection to the database by using a
javax.sql.DataSource object, this file must be in the classpath that indicates the
location of the JDBC driver. If your application creates a connection by using the
java.sql.DriverManager class, this file must be in the classpath. If your application
creates a connection by using a javax.sql.DataSource object, another way to specify
a properties file is to use a file named pdq.dataSourceName.properties in your
application classpath, where dataSourceName represents the name of the DataSource
object.
If you use a properties file to specify pureQuery properties, each line of a properties file
should contain the name of a property, then an equal sign (=), and finally the value for that
property.
11.8.2.1 In practice: Run the application statically
If you are using IBM ® DB2 ® Database for your database, run your application statically.
We will specify our pureQuery properties in a file named
pdq.dataSourceName.properties. The class hrm.HRMDataSourceFactory
defines the javax.sql.DataSource object that Human Resources Manager uses. The
name of the DataSource that the application uses is
DataSourceHumanResourcesManager. Therefore, the name of our properties file is
pdq.DataSourceHumanResourcesManager.properties. Locate this file in the src
directory of the project, and set the pdq.executionMode property in it. In the project, a
single classpath indicates the location of the source code and the location of the JDBC
driver, so this file is in the classpath that indicates the location of the JDBC driver. Listing
11.32 shows what the file should contain.
pdq.executionMode=STATIC
Listing 11.32 - The property to set in your properties file
After you have set the property, run and test your application.
