Java Based OPC UA Server SDK

The OPC UA Java SDK allows efficient development of OPC UA clients and servers, because the Server SDK is bundled with the Client SDK (see the Client SDK product page for more information). Typically OPC UA is used for data acquisition, process monitoring, device diagnostics, etc. The components of the SDK enable you to concentrate on the application design instead of implementing the actual OPC communications. This will reduce the required time and cost of your own development.

As an additional feature the SDK itself is a native Java implementation and depends on the Java Stack and its platform layer and the crypto API defined by the stack.

The Java based Client & Server SDK supports Java Runtime Environment 1.6, 1.7, and 1.8. We’re offering the Java based SDK from our development partner Prosys.
