OSGI Felix with Jasper Reports

Question

I want to create a Module to generate reports using OSGI (Felix in Glassfish),

First, I have downloaded and deployed the Jasper Reports Bundle, The Deploy returns "OK"

After, I have created a Project Bundle that imports the Jasper Reports Packages, the Deploy of Bundle returns "OK"

I take the OutputStream of the Servlet and I Take the Jasper InputStream from another Bundle, and process this with this Code.

public void generateReportFromDatasource(InputStream inputStream,
                                         OutputStream outputStream,
 Map parameters,
 JRDataSource jrDataSource) {

    try {
        JasperRunManager.runReportToPdfStream(inputStream, outputStream,
                parameters,jrDataSource);

    } catch (Throwable e) {
        logger.error(e.getMessage(), e);
    }
}

But, the Jasper Report result is a Error, But i cannot read cleary.

My question is, I don't cant see the Error, because the JasperReports Bundle have the JRStyledTextParser and I cant see the Class that it says that not has Found.

The test unit, (without OSGI) works OK – jrey Oct 23 '14 at 20:47 — jrey, Oct 23 '14 at 20:47

You need to make sure you have all required packages imported. The Manifest of your servlet containing bundle needs to import it like the following:

Package-Import: net.sf.jasperreports.engine.util
