Thank you for your inquiry .
We are sorry but we don't have stand alone Java library for GroupDocs.Assembly product. At the moment we have only GroupDocs.Assembly for .NET and GroupDocs.Assembly for Cloud service (Cloud API). For the API we have Java SDK
and also demo examples
, so you can download and investigate it. The documentation of Java SDK for GroupDocs.Assembly API you will find here
If you will have more questions please feel free to contact us.
