Intermittent EVALUATION COPYRIGHT WARNING on Excel statements from Production environment


We have a web application that is deployed to a two-nodeWeblogic cluster, that sends out both PDF and XLS files that use the Aspose library for formatting and encryption. The web application deployment injects the Aspose licenses as a resource using Spring upon deployment, and we initialize the license as part of normal processing using code similar to the following:

aspose.pdf.License pdfLicense = new aspose.pdf.License();
com.aspose.pdf.kit.License pdfKitLicense = new com.aspose.pdf.kit.License();
com.aspose.cells.License xlsLicense = new com.aspose.cells.License();
com.aspose.words.License wordsLicense = new com.aspose.words.License();


This has been working well for some time, with high daily document volumes (in the thousands).

However, today, we noticed an intermittent issue where only some of the Excel statements were receiving the EVALUATION COPYRIGHT WARNING on the outgoing documents.

Do you have any insight into this problem, and can you offer us any recommendations on how to resolve or troubleshoot this issue?

Please check whether you have set License file successfully for Aspose.Cells for Java and the licensing code is processed fine for your application life cycle. If your licensing code is not processed in the life cycle for the application or the process, it means you are working in evaluation mode, thus, you will have an extra evaluation worksheet.

So, for your web scenario, please make sure that you have placed the licensing procedure at a place where it should be processed at least one time per application process.

Thank you.
