Error during open PDF file in sample application



I try to open PDF file in sample application.

On debug mode I catch an error:
class “com.aspose.pdf.aG$h”'s signer information does not match signer information of other classes in the same package

In Web application I’ve got error (attachment):
Can’t connect to server.

All other file types works correctly.

What can I do to fix it?


Hello Pawel,

2. Environment:

2.2 Ubuntu 15.04 x64,
2.3 Tomcat 8 (I can't use embed Tomcat because it doesn't support JSP file included in Spring sample. Example is broken.
