New Validation Method (v2021 +)
Validate the license key using loadLicense()
Starting in version v2021, Qoppa will send you an xml file that contains your license information and you can use the loadLicense() method to verify your license.
In your Java code, call the loadLicense() method from within your code before making any calls to the library with the full path to the license xml file. The method is static and should be called without instantiating the class first.
// for jOfficeConvert WordDocument.loadLicense("C:\\MyFolder\\qlicense.xml"); // or ExcelDocument.loadLicense("C:\\MyFolder\\qlicense.xml"); // or PowerPointDocument.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFAssemble PDFAssemble.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFFields PDFFields.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFImages PDFImages.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFOptimizer PDFOptimizer.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFPreflight PDFPreflight.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFPrint PDFPrint.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFProcess PDFDocument.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFSecure PDFSecure.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFText PDFText.loadLicense("C:\\MyFolder\\qlicense.xml"); // for jPDFWeb PDFWeb.loadLicense("C:\\MyFolder\\qlicense.xml"); |
Your console will output the validation of your license file

Old Validation Method (v2020-)
Validate the license key using getVersion()
// for jOfficeConvert System.out.println(WordDocument.getVersion()); // or System.out.println(ExcelDocument.getVersion()); // or System.out.println(PowerPointDocument.getVersion()); // for jPDFAssemble System.out.println(PDFAssemble.getVersion()); // for jPDFFields System.out.println(PDFFields.getVersion()); // for jPDFImages System.out.println(PDFImages.getVersion()); // for jPDFOptimizer System.out.println(PDFOptimizer.getVersion()); // for jPDFPreflight System.out.println(PDFPreflight.getVersion()); // for jPDFPrint System.out.println(PDFPrint.getVersion()); // for jPDFProcess System.out.println(PDFDocument.getVersion()); // for jPDFSecure System.out.println(PDFSecure.getVersion()); // for jPDFText System.out.println(PDFText.getVersion()); // for jPDFWeb System.out.println(PDFWeb.getVersion()); |
If the key is invalid, it will show “Demo version” at the end
Below is an example of invalid license:
jOfficeConvert v2020R2.00 - Demo Version
Below is an example of valid license:
jOfficeConvert v2020R2.00
Validate the license key using command-line
Assuming your license key is 123456 for your Production server, you can validate the key against the jar (i.e, make sure you have the good key for the good version), and your server (i.e make sure you have the good key for your server) by using the command(s) below.
// jOfficeConvert java -jar jOfficeConvert.jar -validatekey 123456 // jPDFAssemble java -jar jPDFAssemble.jar -validatekey 123456 // jPDFImages java -jar jPDFImages.jar -validatekey 123456 // jPDFOptimizer java -jar jPDFOptimizer.jar -validatekey 123456 // jPDFProcess java -jar jPDFProcess.jar -validatekey 123456 // jPDFPrint java -jar jPDFPrint.jar -validatekey 123456 // jPDFSecure java -jar jPDFSecure.jar -validatekey 123456 // jPDFText java -jar jPDFText.jar -validatekey 123456 // jPDFWeb java -jar jPDFWeb.jar -validatekey 123456 |
Validate the license key using Java
If the command above validates, but you are still getting watermark when running within your application, you can also validate the key within your Java program inside your environment. Make sure you have jar in the classpath.
// jOfficeConvert WordDocument.KeyInfoWordConvert.main(new String []{"-validatekey", "123456"}); // jPDFAssemble PDFAssemble.KeyInfoAssemble.main(new String[]{"-validatekey", "123456"}); // jPDFImages PDFImages.KeyInfoImages.main(new String[]{"-validatekey", "123456"}); // jPDFOptimizer PDFOptimizer.KeyInfoOptimizer.main(new String[]{"-validatekey", "123456"}); // jPDFProcess PDFDocument.KeyInfoProcess.main(new String[]{"-validatekey", "123456"}); // jPDFPrint PDFPrint.KeyInfoPrint.main(new String[]{"-validatekey", "123456"}); // jPDFSecure PDFSecure.KeyInfoSecure.main(new String[]{"-validatekey", "123456"}); // jPDFText PDFText.KeyInfoText.main(new String[]{"-validatekey", "123456"}); // jPDFWeb PDFWeb.KeyInfoWeb.main(new String[]{"-validatekey", "123456"}); |
If the key is invalid, the following output will show:
Key Validation: Invalid Key
