Hi @Basha!

Here's a code to help you with your problem statement. I have used ZeonPad to convert .msg to .pdf and used PDFBox to merge the pdfs files:

import java.io.File;

public class pdf {


public static void main(String[] args) {

// TODO Auto-generated method stub

String path = "path to folder";

File folder = new File(path);

File[] listOfFiles = folder.listFiles();


for (int i = 0; i < listOfFiles.length; i++) {

String name=listOfFiles[i].getName();

//System.out.println(name);

String substring = name.length() > 4 ? name.substring(name.length() - 4) : name;

//System.out.println(substring);

if (substring.equals(".msg")) {

String fullname=path+"\\\\"+name;

System.out.println(fullname);

System.out.println(substring);

String pdfname=fullname.substring(0, fullname.length() - 4);

pdfname=pdfname+".pdf";

System.out.println(pdfname);

OutlookToPdf outlookToPdf = new OutlookToPdf();

OutlookToPdf.convert(fullname, pdfname);

}


}

File file = new File("path of the new file") 

PDDocument document = PDDocument.load(file);

PDFMergerUtility PDFmerger = new PDFMergerUtility(); 

PDFmerger.setDestinationFileName(path+"/merged.pdf");

for (int i = 0; i < listOfFiles.length; i++) {

String name=listOfFiles[i].getName();

//System.out.println(name);

String substring = name.length() > 4 ? name.substring(name.length() - 4) : name;

//System.out.println(substring);

if (substring.equals(".pdf")) {

String fullname=path+"\\\\"+name;

//System.out.println(fullname);

PDFmerger.addSource(fullname);


}

PDFmerger.mergeDocuments();


}

}

}

Do I have download any jars related to ZeonPad or do i perfrom the above code directly in Eclipse IDE. Please guide me.

Yes, you have to download the jars and use them.
Hi Kishan,

Thanks for your prompt response. I am completely new to java and initial days for me little bit hard.

From where I can download the jar file and also provide the link and name of the jar file.

Regards,

Basha.
You can download the jar from this link: http://www.zeonpad.com/app/CodeBuild/zeonpadpdfconversion_1.0.zip

Just click on the link and the download will begin. I can understand you are learning Java and things get a little confusing at times. You are always welcome to post your queries on the community :)

Thanks Kishan.

In PDF Merger, Is it possible to two images in a single page?

Currently I am using the below code to merge the image to pdf, the result(i.e pdf document) is coming single image single page. Please help.

// This classwill take care convert images to PDF

public static void convertFromImagesToPdf(String FRDID) {

File root = new File(imagesLocation);

String outputFile = FRDID + ".pdf";

List<String> fileList = new ArrayList<String>();

File files[] = root.listFiles();

for (File file : files) {

if (file.isFile() && !file.getName().endsWith(".pdf")) {

fileList.add(file.getName());

}

}

Document document = new Document();

try {

PdfWriter.getInstance(document, new FileOutputStream(new File(root, outputFile)));

} catch (FileNotFoundException e) {

e.printStackTrace();

} catch (DocumentException e) {

e.printStackTrace();

}

document.open();

try {

for (String f : fileList) {

document.newPage();

Image image = Image.getInstance(new File(root, f).getAbsolutePath());

image.setAbsolutePosition(0, 0);

image.setBorderWidth(0);

image.scaleAbsoluteHeight(PageSize.A4.getHeight());

image.scaleAbsoluteWidth(PageSize.A4.getWidth());

document.add(image);

}

} catch (Exception e) {

e.printStackTrace();

}

document.close();

}

If you are asking to add multiple images to the same pdf file, you can try this:

List<String> files = new ArrayList<String>();
		files.add("image1.png");
		files.add("image2.png");

		Document document = new Document();

		PdfWriter.getInstance(document, new FileOutputStream(new File(root, outputFile)));
		document.open();

		for (String f : files) {
			document.newPage();
			Image image = Image.getInstance(new File(root, f).getAbsolutePath());
			document.add(image);
		}
thanks. Let me try if one pdf page having multiple images or not.

Hi Kishan,

Error: PDDocument can't be resolved to a type

To solve this error, you have to set up the PDFBox jar. Please follow these steps:

  1. Download the jar by clicking on this link
  2. Open your project in Eclipse IDE
  3. Then right-click on your project folder in eclipse. 
  4. Go to "Build Path" -> "Configure Build Path"
  5. In the "Java Build Path" section, under the "Libraries" tab, click on "Add External JARs" button.
  6. Choose the JAR file that you downloaded. Click on "Apply and Close"
  7. Close the window
  8. In your code, add the below import:
    import org.apache.pdfbox.*; 

This should solve your error.
