Exception processing particular xls file in Viewer


#1

Hi,


I’ve set up the demo viewer app for java using both spring and servlet examples running on JDK8 and tomcat 8. The viewer is running fine and processing all of the pdf, ppt, doc and xls files we pass to it, except for one particular file (attached). When this file is run through the viewer it just displayed a blank viewer window the following exception is reported in the catelina.out log:

30-Sep-2015 17:05:54.299 SEVERE [http-nio-8080-exec-9] null.null null

java.lang.IllegalStateException: Can't get html content from xls file!

The odd thing is that I tried using the hosted viewer app at apps.groupdocs.com and it works fine there. Please could you help me figure out why it is not working in my local instance?

Thank you,
