I am currently evaluating your product and I deployed your java web sample onto my Tomcat machine. (https://github.com/groupdocs/)
When I try to load a .pdf file (parameter ?file=) only an empty page with a “broken content” icon is displayed. (see attached file)
What can cause this issiue?
The Tomcat version is 7.0.56 (using XAMPP for Windows)
Found the file!
I deployed it as ROOT.war and now it is working!
