Hi Jacky,
Have you upgraded recently from an older version? If so, and especially if you have switched from running Ubuntu 14.04 to 16.04, the first thing I'd recommend would be checking what version of Apache FOP you have installed. AtoM 2.4 requires FOP version 2.1 o work as expected. See:
The other thing you can check is that the error is not in the EAD itself. There are certain reserved characters in XML that, if found in your description, could cause the EAD export to fail, which might generate this message in the Jobs page. For this process to work, the EAD XML must first be able to export - which means it must first be valid XML. This means your EAD may fail to export properly if:
- You’ve used unescaped special characters, such as ampersands & or < and >.
- You’ve used inline HTML elements to style the display of some fields in AtoM - for example, using <em> or <i> elements for emphasis or italics.
- You’ve cut and pasted non UTF-8 encoded characters into AtoM - a common example would be the curvy quotation marks used in many word processing applications like Microsoft Word, instead of the standard UTF-8 straight quotes "
Try exporting the EAD from the description view page - if it exports properly, then this is probably not the issue. If the EAD fails to export and throws an error, then you might want to enter edit mode in the description, and look for some of these possible causes.
Regards,
