public class JasperReportsComponent
extends ComponentBase

Author:

James Dixon and Barry Klawans JasperReports runner for Pentaho. This class implements a Pentaho Component that runs JasperReports. It includes full support for parameterization and output in PDF and HTML. This is a Beta version, with a number of open issues. 1) Data sources must be specified in the config file for EACH report. There should be a default source in the jasper reports configuration. 2) Support for JNDI defined data source has not been added yet. 3) Images are written to the Pentaho temp directory and never cleaned up. They should probably be moved into Session related storage. 4) Support should be added so a Filled report can be persisited into the Pentaho repository and exported repeatedly., Radek Maciaszek Added handling multiple reports in batch mode which allow to create excel reports with multiple worksheets

Method Detail

getLogger

public Log getLogger()

Specified by:

getLogger in class PentahoBase

validateAction

public boolean validateAction()

NOTE: The comments from Pentaho state that in production this will not be called during execution. If so, this info needs to be moved into the execute path as well.

Returns:

true if the validation was successful

executeAction

public boolean executeAction()

Runs a report.

Returns:

true if action was successful

init

public boolean init()

Description copied from interface: IComponent

Initialize the Component. This method is typically called on construction.

Specified by:

init in interface IComponent

Specified by:

init in class ComponentBase

Returns:

returns true if the Component initialized successfully, otherwise returns false

done

public void done()

Description copied from interface: IComponent

Allows the component to perform any cleanup after the execution of the action.

Specified by:

done in interface IComponent

Specified by:

done in class ComponentBase
