genReport -m render creates multiple PDF files

steven.peeters

Hi,
 
I'm currently experimenting using separate run and render tasks using the genReport batch.
I'm doing this so I can the pageNumber and totalPages variables working.
 
I run the batch like this:
genreport -m run hello_world.rptdesign
 
This creates the hello_world.rptdocument file.
 
Next I render this file:
genreport -m render -f PDF -o test.pdf hello_world.rptdocument
 
This creates a new single page PDF for each page in the .rptdocument file.
 
Is there any parameter of script that allows me to create a single PDF file that includes all pages?
 
I've included a simple hello_world.rptdesign as example.
 
Thank you for helping.

This is happening because the org.eclipse.birt.report.engine.api.ReportRunner class called by the batch file is coded to output to multiple files in the renderReport() method.
<pre class="_prettyXprint _lang-js">
for ( long i = 1; i <= pageCount; i++ )
{
String fileName = pathName + '_' + ( i ) + extName;
options.setOutputFileName( fileName );
task.setPageNumber( i );
task.render( );
}
</pre>
You have a couple of options:
 
You can modify the source code to change this behavior to instead render to a single file.
 
Alternatively, you can create your own class based on the ReportRunner class with that portion of the code modified and then point to your custom class instead of the ReportRunner class.
