GroupDocs.Viewer for Java using Servlets API.
File is loading but no any preview available.

Dear Team,

Thanks for your prompt response.

We have chosen to implement GroupDocs.Viewer-for-Java on our application over cloud. Is it sufficient to use “One Developer And One Deployment Location - Developer small business”.

In case of auto scaling process what will happen?

Your above-mentioned query has been answered here.


We wanted to deploy GroupDocs.Viewer Product Family for java plugin into HA mode which will run under auto scaling group which will

run in one location called London.

Currently we are considering to have one developer and one deployment location. So here wanted to know that what is

location stands for in your license pattern?

Please also let us know the best suitable license model after going through our use case.

Please provide quick answer.

Thanks for your cooperation.
