The ACTIVEX component is a Java-wrapper around an ActiveX component. It is only available within the Swing client (not within the FX client).

Please pay attention: binding an ActiveX component into a Swing container is something "quite special" and should in general be avoided - please only use this component as "last option". If using the component please do not forget to spend quite some effort in testing your scenarios (e.g. in 32bit and 64bit Windows environment). 

In many cases it is more stable (and simpler to implement/test) to run some native code as parallel process within the frontend client, and to communicate between the client Java process and the native process using e.g. CLIENTHTTPSENDER and CLIENTHTTPRECEIVER components.
