BufferedImage bufferedImage = new BufferedImage(jasperPrint.getPageWidth() * 4, jasperPrint.getPageHeight() * 4, BufferedImage.TYPE_INT_RGB);

Graphics2D g = (Graphics2D) bufferedImage.getGraphics();

exporter.setParameter(JRGraphics2DExporterParameter.GRAPHICS_2D, g);
exporter.setParameter(JRGraphics2DExporterParameter.ZOOM_RATIO, Float.valueOf(4));
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.exportReport();
g.dispose();

ImageIO.write(bufferedImage, "JPEG", new File("d:/aa.jpg"));

java.lang.NoClassDefFoundError: org/apache/xerces/jaxp/datatype/XMLGregorianCalendarImpl$Parser

When you encounter the following error that related to web service. java.lang.NoClassDefFoundError: org/apache/xerces/jaxp/datatype/XMLGregorianCalendarImpl$Parser Solution 1: Ensure no xercesImpl.jar in your classpath since the implementation of xerce is built-in wiht JAVA SE 1.6. Solution 2: Use XmlJavaTypeAdapter [ @XmlJavaTypeAdapter(JaxbDateAdapter.class)] to convert XMLGregorianCalendar type to Date type. XMLGregorianCalendar is the built-in Java data type for JAXB mapping with datetime. Example: Binding.xjb <?xml version="1.0" encoding="UTF-8"?> <bindings xmlns="http://java.sun.com/xml/ns/jaxb"                 xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"                 xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"                 xmlns:xsd="http://www.w3.org/2001/XMLSchema"                 xsi:schemaLocation=" http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/binding
