Error while running a new emitter programmatically

Hi, 
 
I have a new emitter which I'm trying to run in a Java application. 
My Java application is the same as the ExecuteCSVReport example from the book Integrating and Extending Birt: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>import java.util.logging.Level;
import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.EngineConfig;
import org.eclipse.birt.report.engine.api.IReportEngine;
import org.eclipse.birt.report.engine.api.IReportEngineFactory;
import org.eclipse.birt.report.engine.api.IReportRunnable;
import org.eclipse.birt.report.engine.api.IRunAndRenderTask;
import org.eclipse.birt.report.engine.emitter.html.HTML5RenderOption;

public class ExecuteHTML5Report {

/**
* @param args
* @throws Exception
*/
static void executeHTML5Report() throws Exception {
// TODO Auto-generated method stub
IReportEngine engine = null;
EngineConfig config = null;
config = new EngineConfig();

//config.setEngineHome("");
config.setLogConfig("c:/birt/logs", Level.FINE);
Platform.startup(config);
IReportEngineFactory factory = ( IReportEngineFactory ) Platform.createFactoryObject(
IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
engine = factory.createReportEngine(config);
engine.changeLogLevel(Level.FINEST);

IReportRunnable design = engine.openReportDesign("c://html5Test.rptdesign");
IRunAndRenderTask task = engine.createRunAndRenderTask(design);
String format = "HTML5";
HTML5RenderOption html5Options = new HTML5RenderOption();
html5Options.setOutputFormat(format);
html5Options.setOutputFileName("c://html5Test.html");
task.setRenderOption(html5Options);
task.run();

task.close();
engine.destroy();
Platform.shutdown();
System.out.println("We are done!!");

}

public static void main(String[] args){
try{
executeHTML5Report();
}catch(Exception e){
e.printStackTrace();
}
}
}</pre>
 
I have created this project and added all necessary jars which are mentioned in the book (birt-runtime-4-2-1 and birt-runtime-osgi-4-2-1): 
 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>chartengineapi
com.ibm.icu_4.2.1
commons-cli-1.0
coreapi
crosstabcoreapi
dataadapterapi

odadesignapi
org.apache.commons.codec
org.eclipse.emf.common
org.eclipse.emf.ecore
org.eclipse.emf.xmi
org.w3c.css.sac
scriptapi
</pre>
 
When I run the application I get following exception:

When I add all jars from (birt-runtime-4-2-1 and birt-runtime-osgi-4-2-1) I get following error:

Hopefully someone knows how to resolve it. 
 
Thanks and Cheers,

Hi,

this error is caused by adding jars twice. The reason for that is that you have to decide wether to use birt-runtime-4-2-1 OR birt-runtime-osgi-4-2-1. If you add both it will end in the error you are seeing now. Perhaps the book is outdated, because starting with 3.7 you have to decide wether to use OSGI or not to use OSGI.
I suggest to try your plugin with both, the non osgi and the osgi version of the engine.
to run the osgi version unzip it and add everything in ReportEngine/lib to the classpath of your application. But the other content below ReportEngine to a directory somewhere on your disc. Use the setBIRTHome (or setEngineHome) command in your java code to tell it where you put that directory.
If you want the non-osgi use the birt-runtime-4-2-1. Add everything in ReportEngine/lib to the classpath of your application. Do not call setBIRTHome (or setEngineHome)

Hi cbrell, 
 
If I use the non-osgi Version I get an Exception that the OSGI framework coudln't start. 
I've tried the osgi Version and added 
<pre class='_prettyXprint _lang-auto _linenums:0'>config.setEngineHome("C:/birt-runtime-4_2_1/birt-runtime-4_2_1/ReportEngine");</pre>
to my application. 
I copied the jars from the osgi version to the folder you can see above. 
 
Now I get this error: 
<pre class='_prettyXprint _lang-auto _linenums:0'>Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/runtime/CoreException

Thanks,

I got it now. I forgot to add the plugins of the osgi version.

Thank you!
