Hi all, Received an update from the engineering team via daycare.So, the right way to register the Preprocessor is to implement the PreProcessor interface but register it as an IProcessor service. @component((immediate = true)) @Service((IProcessor.class)) public class MyPreProcessor implements IPreProcessor { private static final Logger LOG = LoggerFactory.getLogger(MyPreProcessor.class); //Implementation here }

Hi Naresh,For Dynamically populating items please use article Dynamically populate a drop-down list or list box​ for connecting to data sources.

Hi,Yes, you can use FormsService​ API for generating interactive PDF.Sample codebyte[] xdpData = (data);Document docData = new Document(xmlData);PDFFormRenderOptions options = new PDFFormRenderOptions();options.setContentRoot(xdpLocation); // location of XDP Document docPDF = formsService.renderPDFForm(fileName,docData,options);byte[] result = IOUtils.toByteArray(docPDF.getInputStream());
