The. class is an example of how to run a PDI job from Java code in a stand-alone application. When the transformations have completed, call KettleEnvironment.shutdown() to ensure the proper shutdown of all kettle listeners. To get more information, retrieve the transformation log lines. This method returns zero ( 0) on success and a non-zero value when there are errors. The ResultВ object can be queried for success by evaluating getNrErrors(). To ensure that all steps of the Trans object have completed, call waitUntilFinished().ДЄfter the Trans object completes, you can access the result using getResult(). The Trans object starts,В then executes asynchronously. To query the assigned values, use setParameterValue().ДЄn executable TransВ object is derived from the TransMeta object that is passed to the constructor. To query the declared parameters of the transformation definition use listParameters(). ktr file, a PDI repository, or generate it dynamically. The definition of a PDI transformation is represented by a TransMetaВ object. ktr file using runTransformationFromFileSystem() or from a PDI repository using runTransfomrationFromRepository().Д¬onsider the following general steps while trying to run an embedded transformation:ДЄlways make the first call to KettleEnvironment.init() whenever you are working with the PDI APIs.

This class sets parameters and executes the sample transformations in pentaho/design-tools/data-integration/etlВ directory. The. class is an example of how to run a PDI transformation from Java code in a stand-alone application. StepPluginType.getInstance().getPluginFolders().add( new PluginFolder( '', false, true ) ) You can also add custom plugins in other locations as long as they are registered with the appropriate implementation of PluginTypeInterface prior to initializing the kettle environment, as shown in the following code example: Once the plugin location(s) are properly configured, you can add custom plugins to your specific locations.

Set the KETTLE_PLUGIN_BASE_FOLDERS system property to point to the PDI pentaho/design-tools/data-integration directory, either through the following command line option ( -DKETTLE_PLUGIN_BASE_FOLDERS=/data-integration) or directly in your code ( tProperty( 'KETTLE_PLUGIN_BASE_FOLDERS', new File('/data-integration') ) for example).

Copy the pentaho/design-tools/data-integration/plugins directory into the /plugins directory of your application.

You can use either of following methods to make the default kettle plugins available: With a standard install, the kettle engine looks for plugins in either plugins or /.kettle/plugins.
