Converter - Java Main

XDocReport give you the capability to convert generated docx report to another format like XHTML and PDF.

XDocReport converter are modular, it means that you can choose the converter implementation and implement your own converter if you need.

XDocReport provides several converter implementation (2 PDF via FOP with XSL, 2 PDF via IText with POI-HWPF...) After developing several implementation we choose to keep 2 PDF via IText with POI-HWPF because it's more performant and it's more easy to develop Java code instead of developing XSL.

If you wish to :

  • use Docx with Freemarker and convert report To PDF/XHTML, you could download *docxandfreemarker.converter--**-sample.zip.
  • use Docx with Velocity and convert report To PDF/XHTML, you could download *docxandvelocity.converter-**-sample.zip.

1. Add XDocReport JARs

Add first you must add in your Java project the same JARs explained at Java Main section.

Docx Converter JARs

**JARs name** **Description** **OSGi Bundle/Fragment**
fr.opensagres.xdocreport.converter.docx.xwpf PDF/XHTML XDocReport converter implementation Fragment -> fr.opensagres.xdocreport.converter

Docx Converter JARs

**JARs name** **Description** **OSGi Bundle/Fragment**
org.apache.poi.xwpf.converter POI converter Bundle
fr.opensagres.xdocreport.itext.extension XHTML+IText extension

POI JARs

**JARs name** **Description** **OSGi Bundle/Fragment**
poi-3.11.jar POI org.apache.poi
poi-ooxml-3.11.jar POI OOXML org.apache.poi
ooxml-schemas-1.1.jar OOXML Schemas org.apache.poi
xmlbeans-2.3.0.jar XML Beans org.apache.xmlbeans
dom4j-1.6.1.jar DOM4J dom4j

IText JARs

If you wish generate PDF, add IText JARs :

**JARs name** **Description** **OSGi Bundle/Fragment**
[itext-2.1.7.jar](http://search.maven.org/#artifactdetails|com.lowagie|itext|2.1.7|jar) IText PDF Bundle

XHTML

Instead of doing :

report.process(context, out);

you must do :

Options options = Options.getTo(ConverterTypeTo.XHTML).via(ConverterTypeVia.POI);
report.convert(context, options, out);

2. Simple field 2 XHTML

package fr.opensagres.xdocreport.samples.docxandvelocity;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

import fr.opensagres.xdocreport.samples.docxandvelocity.model.Project;
import fr.opensagres.xdocreport.template.IContext;
import fr.opensagres.xdocreport.template.TemplateEngineKind;

public class DocxProjectWithVelocity2XHTML {

	public static void main(String[args) {
		try {
			// 1) Load Docx file by filling Velocity template engine and cache
			// it to the registry
			InputStream in = DocxProjectWithVelocity2XHTML.class
					.getResourceAsStream("DocxProjectWithVelocity.docx");
			IXDocReport report = XDocReportRegistry.getRegistry().loadReport(
					in, TemplateEngineKind.Velocity);

			// 2) Create context Java model
			IContext context = report.createContext();
			Project project = new Project("XDocReport");
			context.put("project", project);

			// 3) Generate report by merging Java model with the Docx
			OutputStream out = new FileOutputStream(new File(
					"DocxProjectWithVelocity_Out.html"));
			// report.process(context, out);
			Options options = Options.getTo(ConverterTypeTo.XHTML).via(
					ConverterTypeVia.XWPF);
			report.convert(context, options, out);

		} catch (IOException e) {
			e.printStackTrace();
		} catch (XDocReportException e) {
			e.printStackTrace();
		}
	}
}

2 PDF via IText with POI-XWPF

Instead of doing :

report.process(context, out);

you must do :

Options options = Options.getTo(ConverterTypeTo.PDF).via(ConverterTypeVia.XWPF);
report.convert(context, options, out);
