Aspose PDF ComboBoxField Linux RedHat Enterprise 7.2 64bits

Hello, I’ve tried to use both Aspose.PDF 17.3 and 17.5 for Java, hoping that this issue would be solved, but seems like it keeps showing up.

The problem is that I can use ComboBoxField successfully on Windows, but running the same code (application) on Linux RedHat 7.2 64bit, both with Apache Tomcat 8.5.15, the select control won’t be added on the generated PDF document.
The constructor used is ComboBoxField combo = new ComboBoxField(pdfDocument, textRect). I’ve successfully added the ComboBoxField on Linux using the new ComboBoxField() constructor, but when I try to set the position (rectangle), the problem shows up again, so I believe there are some problems regarding the positioning rectangle.

Thanks for contacting support.

Can you please confirm if the problem is occurring with some specific document or it is occurring for all the files when using code snippet over Linux platform. From your above code snippet and description, it appears that you are adding ComboBoxField to PDF file but we need some details on either you are adding it to the document being generated from scratch or you are adding it to an existing PDF file.

Please share the details, so we may reply accordingly. We are sorry for this inconvenience.

Hello @codewarior,

I have a document already loaded, and based on some specific tags, I am trying to replace those tags with various input field types. Everything works as expected both on Windows and Linux, excepting this ComboBoxField. If you need further details, I can help you.

Hello @codewarior,

Is there any way I can see the status of the ticket?
Thank you for your patience, too!



Thanks for your inquiry.

We have further investigated the issue at initial stage and according to our findings, the issue is encountering due to absence of basic fonts in the Linux environment. Though in your code, you were not using or setting any specific font during PDF generation but the API was using “Times New Roman” font as default, and that font must be present in the environment.

You can please try this scenario after installing the essential fonts in the Linux, which you are using and in case if you face any other issue, please feel free to let us know.

Best Regards,
