Générer un fichier PDF interactif
Voici le code de servlet responsable du rendu du PDF interactif et du renvoi du PDF à l’application appelante. Le servlet appelle la méthode mobileFormToInteractivePdf
du service OSGi DocumentServices personnalisé.

Effectuer le rendu d’un fichier PDF interactif
Le code suivant utilise l’API Forms Service pour effectuer le rendu du PDF interactif avec les données du formulaire mobile.
package com.aemforms.mobileforms.core.documentservices.impl;
import com.adobe.aemfd.docmanager.Document;
import com.adobe.fd.forms.api.AcrobatVersion;
import com.adobe.fd.forms.api.FormsService;
import com.adobe.fd.forms.api.FormsServiceException;
import com.adobe.fd.forms.api.PDFFormRenderOptions;
import com.aemforms.mobileforms.core.documentservices.GeneratePDFFromMobileForm;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Reference;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@Component(service = GeneratePDFFromMobileForm.class, immediate = true)
public class GeneratePDFFromMobileFormImpl implements GeneratePDFFromMobileForm {
@Reference
FormsService formsService;
private transient Logger log = LoggerFactory.getLogger(this.getClass());
@Override
public Document generateInteractivePDF(Document xmlData, String xdpPath)
{
String uri = "crx:///content/dam/formsanddocuments";
String xdpName = xdpPath.substring(31, xdpPath.lastIndexOf("/jcr:content"));
log.debug("####In mobile form to interactive pdf#### " + xdpName);
PDFFormRenderOptions renderOptions = new PDFFormRenderOptions();
renderOptions.setAcrobatVersion(AcrobatVersion.Acrobat_11);
renderOptions.setContentRoot(uri);
Document interactivePDF = null;
try
{
interactivePDF = this.formsService.renderPDFForm(xdpName, xmlData, renderOptions);
}
catch (FormsServiceException e)
{
log.error(e.getMessage());
}
return interactivePDF;
}
}
