XMLPropertyListConfiguration / Plist Parser example


XMLPropertyListConfiguration is having a fantastic API to work with plist files. But there is no much example for this library. After some googling and library analysis, it came to know that it is very very easy to parse the files !. Here is the example.


    @Test
    public void test() {
        try {
            String plistFile = "/Users/plistFile/info.plist";
            XMLPropertyListConfiguration plist = new XMLPropertyListConfiguration();

            HashMap life = new HashMap();
            life.put("Home", "home.png");
            life.put("Office", "browse.png");
            life.put("School", "mycart.png");
            life.put("College", "offers.png");
            plist.addProperty("Life", life);
           
            HashMap phones = new HashMap();
            phones.put("Nokia", "8000");
            phones.put("Samsung", "4000");

            List<String> imagesArray = new ArrayList<String>();
            imagesArray.add("icon1.png");
            imagesArray.add("icon2.png");
            imagesArray.add("icon3.png");
            phones.put("PhoneIcons", imagesArray);
            plist.addProperty("Phones", phones);
           
            List<String> imagesArray1 = new ArrayList<String>();
            imagesArray1.add("icon1.png");
            imagesArray1.add("icon2.png");
            imagesArray1.add("icon3.png");
                       
            Map dashBoard = new HashMap();
            dashBoard.put("imgArray", imagesArray1);

            plist.addProperty("ImageArrayBoard", dashBoard);
            plist.addProperty("ImageArray.innnerLevelTag", "IamInnerLevelTag");
            plist.save(plistFile);

            System.out.println("File saved .... ");
        } catch (Exception e) {
            System.out.println(e.getLocalizedMessage());
        }
    }

Thats All, Happy Coding :)

How to print base64 image in jasper report pdf ?

1 comment: Posted by Kaleeswaran at 10:44 PM Labels: , , ,

How to print base64 image in jasper report pdf ?

1) import base64 class in jrxml file <import value="org.apache.commons.codec.binary.Base64"/>

2) Create two parameters logo and base64Img in jasper report.

3) logo parameter class as String (java.lang.String) and

4) base64Img parameter class as InputStream (java.io.InputStream) and

5) base64Img parameter Default Value expression should be like "new ByteArrayInputStream(new Base64().decodeBase64($P{logo}.getBytes("UTF-8")))"

Thats all..

Note :
parameter class - specifies the type of that parameter
Default Value expression - just like method. we can write our implementation here.

    @Test
    public void base64ImageAsStream() {
        try {
            compileReports();
            System.out.println("report ");
            String outFileNamePDF = "/Users/user/Tried/POC/imageStreamToPdf/base64ImageStream.pdf";
            new File(outFileNamePDF).getParentFile().mkdirs();
            String containerJrxmlFile = "/Users/user/Tried/POC/imageStreamToPdf/imageToStreamPdf.jrxml";
           
            Map<String, Object> parameters = new HashMap<String,Object>();
            File img = new File("/Users/user/Desktop/wallpaper.jpg");
            InputStream fis = new FileInputStream(img);
           
            byte[] imgByte = null;
            imgByte = IOUtils.toByteArray(fis);
            byte[] encodedImage = Base64.encodeBase64(imgByte);
            String encodeImg = new String(encodedImage);
           
            System.out.println("printnng");
            parameters.put("logo", encodeImg);
           
            InputStream reportStream = new FileInputStream(containerJrxmlFile);
            BufferedInputStream bufferedInputStream = new BufferedInputStream(reportStream);
            JasperDesign jasperDesign = JRXmlLoader.load(bufferedInputStream);
           
//            JasperReport jasperReport = (JasperReport) JRLoader.loadObject("/Users/user/Tried/POC/imageStreamToPdf/imageToStreamPdf.jasper");
           
            JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, new JREmptyDataSource());
           
            JRExporter exporter = new net.sf.jasperreports.engine.export.JRPdfExporter();
            exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileNamePDF);
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
            exporter.exportReport();
           
            System.out.println("pdf report created .... ");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Enjoy the coding !!!

How to apply dynamic colors to jasper report ?

How to apply dynamic colors to jasper report ?

After some googling, i found the way to apply colors dynamically to jasper report.

My working code is,

We can access all the jasper files styles and everything with the help of JasperDesign class.
Just create some styles like header, body and footer and set colors for those style from java file.

The code "styleList[j].setBackcolor(userBackGRDColor);" - sets the back groud color of a style

    @Test
    public void dynamicColorPdf() {
        try {
            System.out.println("pdf report creation started .... ");

            String outFileNamePDF = "/Users/user/Tried/POC/imageStreamToPdf/dynamicColorPdf.pdf";
            new File(outFileNamePDF).getParentFile().mkdirs();
            String containerJrxmlFile = "/Users/user/Tried/POC/imageStreamToPdf/dynamicColorPdf.jrxml";
           
            Map<String, Object> parameters = new HashMap<String,Object>();
           
            InputStream reportStream = new FileInputStream(containerJrxmlFile);
            BufferedInputStream bufferedInputStream = new BufferedInputStream(reportStream);
            JasperDesign jasperDesign = JRXmlLoader.load(bufferedInputStream);
           
            JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, new JREmptyDataSource());
           
            // applying styles
            java.awt.Color userForeColor = new java.awt.Color(255, 69, 0);
            java.awt.Color userBackGRDColor = new java.awt.Color(255, 0, 0);
            JRStyle[] styleList = jasperPrint.getStyles();
            System.out.println("styleList.length => " + styleList.length);
            for (int j = 0; j < styleList.length; j++) {
                System.out.println("styleList[j].getName() => " + styleList[j].getName());
                    if (styleList[j].getName().equals("style1")) {
                            styleList[j].setBackcolor(userBackGRDColor);
                            styleList[j].setForecolor(userForeColor);
                            jasperPrint.addStyle(styleList[j], true);
                    } else if (styleList[j].getName().equals("style2")) {
                        styleList[j].setBackcolor(userBackGRDColor);
                            styleList[j].setForecolor(userForeColor);
                            jasperPrint.addStyle(styleList[j], true);
                    }
            }
           
            JRExporter exporter = new net.sf.jasperreports.engine.export.JRPdfExporter();
            exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileNamePDF);
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
            exporter.exportReport();
           
            System.out.println("pdf report created .... ");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Happy coding :)

How to image stream to jasper report ?

How to image stream to jasper report ?

It is very easy to pass image stream to jasper report pdf.

Steps are,

1) Convert the image to stream and set it in parameter ("logo")
2) In jrxml file , create a parameter with parameter class as "java.io.InputStream"
3) Place a image on the jrxml design, set "Image Expression" to $P{logo} and "Expression class" to java.lang.String

    @Test
    public void createPdfWithImageAsStream() {
        try {
            System.out.println("pdf report creation started .... ");

            String outFileNamePDF = "/Users/user/Tried/POC/imageStreamToPdf/createPdfWithImageAsStream.pdf";
            new File(outFileNamePDF).getParentFile().mkdirs();
            String containerJrxmlFile = "/Users/user/Tried/POC/imageStreamToPdf/createPdfWithImageAsStream.jrxml";
           
            // pass logo as stream.
            Map<String, Object> parameters = new HashMap<String,Object>();
            File img = new File("/Users/user/Desktop/wallpaper.jpg");
            InputStream fis = new FileInputStream(img);
            System.out.println("printnng");
            parameters.put("logo", fis);
           
            InputStream reportStream = new FileInputStream(containerJrxmlFile);
            BufferedInputStream bufferedInputStream = new BufferedInputStream(reportStream);
            JasperDesign jasperDesign = JRXmlLoader.load(bufferedInputStream);
           
            JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, new JREmptyDataSource());
           
            JRExporter exporter = new net.sf.jasperreports.engine.export.JRPdfExporter();
            exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outFileNamePDF);
            exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
            exporter.exportReport();
           
            System.out.println("pdf report created .... ");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Happy coding :)
