Upgrading report definitions for newer BIRT version? [message #630751]

I have a set of report definitions (rptdesign xml files) that were developed under BIRT 2.5.0. After upgrading to 2.6.1, there are appearance changes such as

Some (not all) subheaders and footers no longer display/print
In a bubble chart, bubble sizes are much larger than they were in 2.5.0

I've tried opening and saving the report definitions in the newer report designer but it doesn't change anything. Is there a procedure for upgrading older report definitions to work with the newer BIRT?

I figured out that "Save As..." will update the rptdesign file to 2.6.1 compatibility. However I have a large number of such files. Is there a way to automate the upgrade process?

Jim,

I do not think we have anything to do this quickly, but you could write
a simple DE API app that opens all the rptdesigns in a folder and does
the save.

That's the direction I'm headed

I'm a strong Java developer but a complete noob with regards to Eclipse plugins. I've read a lot of the "getting started" material on the Eclipse site, but there seems to be quite a bit of undocumented "plugin lore" that one has to learn. For example, the docs are all written from the perspective of adding new functionality, with little covering the USE of existing commands. I could not find a list anywhere of the available org.eclipse.ui.* command IDs.

Is there anything with examples of using the PDE API to do things like

enumerate the files in a directory
iterate over the list, opening each one in the report designer, then issuing a "Save As..." command

Jim,

I was just thinking to do it with a command line app like the following:

import java.io.File;
import java.io.IOException;

import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.model.api.DesignConfig;
import org.eclipse.birt.report.model.api.IDesignEngine;
import org.eclipse.birt.report.model.api.IDesignEngineFactory;
import org.eclipse.birt.report.model.api.ReportDesignHandle;
import org.eclipse.birt.report.model.api.SessionHandle;
import org.eclipse.birt.report.model.api.activity.SemanticException ;

import com.ibm.icu.util.ULocale;

/**
* Simple BIRT Design Engine API (DEAPI) demo.
*/

public class FileIterSave
{

public static void main( String[] args )
{
try
{
updateReports( );
}
catch ( IOException e )
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch ( SemanticException e )
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}

static void updateReports( ) throws IOException, SemanticException
{
// Create a session handle. This is used to manage all open designs.
// Your app need create the session only once.

DesignConfig config = new DesignConfig( );

config.setBIRTHome("C:/birt/birt-runtime-2_5_1/birt-runtime-2_5_1/ReportEngine ");
IDesignEngine engine = null;
try{

Platform.startup( config );
IDesignEngineFactory factory = (IDesignEngineFactory) Platform
.createFactoryObject(
IDesignEngineFactory.EXTENSION_DESIGN_ENGINE_FACTORY );
engine = factory.createDesignEngine( config );

}catch( Exception ex){
ex.printStackTrace();
}

SessionHandle session = engine.newSessionHandle( ULocale.ENGLISH ) ;

ReportDesignHandle design = null;
try{

File f1= new File("C:/work/TestReports/");

File []fileList = f1.listFiles();

for(File f2:fileList){

System.out.println(f2.getPath());

design = session.openDesign(f2.getPath());

design.save();

design.close( );

}

Platform.shutdown();

}catch(Exception e){
e.printStackTrace();
}
System.out.println("Finished");

// We're done!
}

}

Cool. So you're running the designer "headless".

I've actually dipped my toe into the Plugin Development waters and now see a whole bunch of potential uses for a custom plugin, so I'm going to pursue that avenue.

It's nice to know that BIRT can be run headless, and I'll keep that option in mind.

Thanks!
