Use the tJasperOutput component to run a Jasper Report from Talend Open Studio. This component allows a report to be produced after a data flow is executed.
At the end of processing a data set -- say loading source data into an RDBMS -- you may want to publish static HTML, text, or PDF reports (or all). This establishes a dependency between the two activities; nothing is published if a loading component failed. The report publishing subjobs could then be followed with a tFTP put.
To execute a Jasper Report from Talend Open Studio, add a tJasperOutput component to the canvas. Use a flow to invoke the component. This example uses a single-row tRowGenerator.

Simple Jasper Report Creation from TOS |
Configure the tJasperOutput by specifying the JRXML file, the output file name, and the report type (PDF, HTML, etc.). Also, make sure that there is a valid iReport command. Add the file path to the ireport executable. Test this with the "Launch" button.

Configuring tJasperOutput |
This post used the following simple (no datasource) example Jasper Report. All of the bands except for Title are removed. Title contains a single Static Text "Hello, World!". An Empty Datasource is specified in the toolbar.

And the result is a PDF in the output folder

When starting with tJasperOutput, try using a simple Jasper Report based on a string constant. This post is a good test to verify that TOS and iReport can communicate. Future posts will deal with datasources and parameters.
