Old version 7.5.3 had similar problem.

Thanks,
Chang Shin

Thanks,

HI Chang,


Thank you for contacting Aspose support.

As your presented scenario involves multiple Aspose APIs therefore it is hard to detect which API is contributing most to the problem as stated in your post. It would be of great help in isolating the problem cause, and to provide a fix if you can provide a sample console application replicating your complete scenario along with template input files. As soon as we review the aforesaid information, we will be in a better position to assist you further in this regard.

I just tested 8.0.1. I have same error message.
I can’t send out any company document file.

Thanks,
Chang Shin

Hi Chang,


Sorry to know that the latest version didn’t help in your scenario.

I am afraid, we may not be able to identify the problem cause without your help in this regard. Therefore we would request you again to create a sample application just for issue replication and share your input file after removing any sensitive information. Moreover, if you do not wish to share the sample on public forum, you may send an email using the “Contact” button on post window.

Thanks in advance for your cooperation & understanding.

Fortunately, we made up the phony data and got the same error message.
Please test attached excel file on Mac OS. then let me know.

Thanks,
Chang Shin

Hi Chang,


Thank you for providing the sample spreadsheet.

We are looking into this matter to reproduce the said exception, and we will shortly get back to you with updates in this regard.

Hi Chang,


We have tested your provided spreadsheet on MAC OS 10.8.3 with JDK 1.6.0_25 against the latest build of Aspose.Cells for Java 8.0.1. Unfortunately, we are unable to experience any exception with the following piece of code. Please check the attached resultant PDF file for your reference.

Java

Workbook book = new Workbook(myDir + “2014 Q1 - memeyouyou techno.xls”);
book.save(myDir + “output.pdf”, SaveFormat.PDF);

In order to move further with the stated issue, we will require a sample console application as requested before to replicate the issue, and to move forward towards the correction.

It is my code:

The red light line, pbeRoot.setSubEntry(subEntryList); has the error message.

// http://www.aspose.com/docs/display/cellsjava/Add+PDF+Bookmarks

Hi Chang,


Thank you for providing complete source code. As a standard procedure, I have quickly tested the source code snippet against your provided spreadsheet with Aspose.Cells for Java 8.0.1 on Windows 7 platform. Unfortunately, I was unable to see any exception therefore I am now moving forward to test the same on MAC OS. I will shortly respond back with more details in this regard.

Hi Chang,


We have executed your provided code against the latest version of Aspose.Cells for Java 8.0.1 and your provided spreadsheet. Unfortunately we were unable to see any exception during the process. Please find the attachment for the resultant PDF file.

Please confirm the following on your end in order to make sure that we moving towards the right direction,

  1. You are using the latest version of Aspose.Cells for Java 8.0.1. Please note, you have to reference two Jar files in your project, that is; aspose.cells-8.0.1.jar & bcprov-jdk16-146.jar. We would suggest you to remove the references and add them again to give it another try.
  2. Please confirm the recently shared code snippet and previously shared source template spreadsheet would enable us to experience the exception.
  3. In you first post as quoted below, the exception seems to be thrown by Workbook.save method whereas in your recent comments you have mentioned that the pbeRoot.setSubEntry(subEntryList) statement is triggering the exception. Please provide the complete exception message and stack trace.
