public static void insertWatermarkPdf(String path, String fileName, String watermarkText) {

	PdfFileStamp fileStamp = new PdfFileStamp();

	fileStamp.bindPdf(path+fileName);

	FormattedText formattedText = new FormattedText(watermarkText, java.awt.Color.GRAY, java.awt.Color.WHITE, FontStyle.Helvetica, EncodingType.Winansi, false, 50);

	fileStamp.setStartingNumber(1);

	Stamp stamp = new Stamp();
	stamp.bindLogo(formattedText);
	stamp.setRotation(52f);
	stamp.setBackground(Boolean.FALSE);

@praveen043,

We have tested your scenario with the latest version 18.5 of Aspose.PDF for Java API, and could generate the output PDF without any error. This is the output PDF: Output.pdf (1.7 MB). Please make sure that you have added the reference of Aspose.PDF for Java API in your application project, and also try with the latest version 18.5.

This code is working fine by executing main method. But when we run the same using Tomcat application server (with Spring MVC framework) it’s giving error, which I have mentioned at first time in forum.
Please check the same as per given mentioned scenario.

@praveen043,

We have tested your scenario in our Tomcat environment with the latest version 18.6 of Aspose.PDF for Java API, and the code works fine. This is the output PDF: angularjs_Output18.6.pdf (1.7 MB). Please create a small project application, which reproduces this error in your environment, and then send us a ZIP of this project. We will investigate your scenario in our environment, and share our findings with you.

Dear team please provide the quick response regarding that. There are too much time passed.

@praveen043

Thank you for elaborating it further.

We have managed to reproduce the problem in our environment. There appeared some FileNotFoundExceptions and we had to create folders and PDF file based on the file paths specified in your application. However, the reason for this problem is still unclear. Therefore, we need the source code instead of deployed version of your application to investigate and sort it out.

We have investigated the project shared by you and have noticed that there is no dependency declared for Aspose.PDF for Java 18.7 API in pom.xml file of your web application. Please ensure declaring dependency of Aspose.PDF and then share your kind feedback with us.

    <groupId>com.aspose</groupId>
    <artifactId>aspose-pdf</artifactId>
    <version>18.7</version>
    <type>jar</type>
</dependency>

Your application is working fine as we have tested with a blank PDF document and generated PDF file has been attached for your kind reference TextStamp_output.pdf. We hope this will be helpful. Please feel free to contact us if you need any further assistance.

We have uploaded the working version of project with all dependencies resolved and you can download it from this Google Drive link and then share your kind feedback with us.

Problem occurs during downloading.

@praveen043

The problem can occur because of some internet issues. Please ensure stable internet connection and try again because the file is downloading fine.

Now it’s working. But added watermark only 4 pages.
Is it restriction at trial version or anything wrong in logic.

@praveen043,
