Unable to load License for Aspose.PDF for Java

cdang1 · June 25, 2023, 6:59pm

Hello Aspose team,

I just received a temp license for Aspose.PDF for Java, and tried to use the license file according the instruction for PDF Java at the following page:

However, I kept getting the following error:
“Signature length not correct: got 256 but was expecting 128”

If I’m following the wrong steps/section, please point to the correct section.

Here’s the screenshot of my IDE trying to run your sample code to load the license file:

Thanks,

Could you please make sure that you are using the license with the latest version of the API? In case issue still persists, please share your license file with us so that we can test the scenario in our environment and address it accordingly.

Thank you for the response.
I actually didn’t write my own code. I was only trying to do was test the following example code offered by Aspose. All that I did was add the code snippet for loading the license file so that I can test this code against large XFA files.

github.com

aspose-pdf/Aspose.PDF-for-Java/blob/master/Examples/src/main/java/com/aspose/pdf/examples/AsposePdfExamples/Forms/ConvertDynamicXFAFormToStandardAcroForm.java

package com.aspose.pdf.examples.AsposePdfExamples.Forms;

import com.aspose.pdf.Document;
import com.aspose.pdf.FormType;

public class ConvertDynamicXFAFormToStandardAcroForm {

	public static void main(String[] args) {
		// Load dynamic XFA form
		Document document = new Document("XFAform.pdf");
		// Set the form fields type as standard AcroForm
		document.getForm().setType(FormType.Standard);
		// Save the resultant PDF
		document.save("Standard_AcroForm.pdf");
	}

}

I was able to resolve the issue by doing the following:

Updated the Aspose-PDF version to 21.12 in pom.xml here:
https://github.com/aspose-pdf/Aspose.PDF-for-Java/blob/master/Examples/pom.xml#L28
Fixed a bunch of example code that are no longer compatible with the latest version of API. This needed in order for the sample code project to compile.
