Qoppa’s PDF libraries and components will throw exceptions as expected and developers can decide to redirect the exceptions to their users, log them or handle them as needed.

To  debug a specific issue, developers can use the following system properties / command lines arguments:

Debug Flag

-qoppa.debug=true

to output exception logs and additional information to the console. Used to be “-DDebug=true” in version 2013R2 and earlier.

Development Flag

-qoppa.dev=true

to output even more information to the console. It is not recommended to turn this flag on in production mode as some exceptions may be thrown instead of handled silently when in “dev” mode. Used to be “-DDebug=true” in version 2013R2 and earlier.
