    OdaDataSourceHandle dsHandle = (OdaDataSourceHandle)
reportDesignHandle.getDataSources().get(0);
    dsHandle.setProperty("FILELIST", fileNameDataset);
    dsHandle.setProperty( "ENCODINGLIST", "UTF-8" );

The data set has no such property. What's the purpose?

Comment 2 Christoph Henniger 2010-05-26 04:08:40 EDT

i need to set the dataset while executing the report to a dynamically generated xml-file.

there is no such property? but the first run works!?

i found this solution in this faq: ftp://ftp-developpez.com/business-intelligence/faq/birt/faqbirt.pdf

Comment 3 Christoph Henniger 2010-05-26 04:10:13 EDT

sorry: i need to set the data source dynamically

Do you use ODA data source? Only for ODA data source, it can define its own properties. Can you please attach the report design.

BTW, I cannot access the pdf you mentioned.

Comment 6 Christoph Henniger 2010-05-26 04:37:11 EDT

yes - i used an oda data source. i there another way?

BTW: pdf on ftp works for me ;)

As a workaround, you can start and shutdown the platform only once. For
example:

public void main() throws BirtException, FileNotFoundException {
    startEngine();
    generateReport(); // ok
    generateReport(); // exception see below
    shutdownEngine();
}

IReportEngine engine;

public void startEngine()
{
    String birtHomeDirectory = "...";
    EngineConfig config = new EngineConfig();
    config.setEngineHome(birtHomeDirectory);

    Platform.startup(config);
    IReportEngineFactory factory = (IReportEngineFactory)
    Platform.createFactoryObject(
    IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );

    engine = factory.createReportEngine( config );
}

public shutdownEngine() 
{
    engine.destroy();
    Platform.shutdown();
    engine = null;
}

public void generateReport() throws BirtException, FileNotFoundException {
    String fileNameReport = "...";
    String fileNameDataset = "...";

    IReportRunnable design = engine.openReportDesign(new
FileInputStream(fileNameReport));
    ReportDesignHandle reportDesignHandle = (ReportDesignHandle)
design.getDesignHandle();

    OdaDataSourceHandle dsHandle = (OdaDataSourceHandle)
reportDesignHandle.getDataSources().get(0);
    dsHandle.setProperty("FILELIST", fileNameDataset);
    dsHandle.setProperty( "ENCODINGLIST", "UTF-8" );

    IRunAndRenderTask task = engine.createRunAndRenderTask(design);

    HashMap contextMap = new HashMap();
    task.setAppContext(contextMap);

    PDFRenderOption options = new PDFRenderOption();
    options.setOutputStream(new ByteArrayOutputStream());
    options.setOutputFormat("pdf");
    task.setRenderOption(options);

    task.run();
    task.close();
}

Comment 9 Christoph Henniger 2010-05-26 04:50:11 EDT

I've simplified the usecase for reproduction.

My original program only restarts the engine, if the first generating step
fails.
If i do not restart the engine after an exception, it will sometimes hang up
during the second step.

Looks like there is some issue for class loading for the 2nd time to run report. Will get back to you later.

Comment 11 Xuelan Li 2010-06-02 23:31:11 EDT

fixed.
