B4J Question How to use an .ocx library?

[vecino]

Hello, a customer tells me: "I have a fingerprint reader that only comes with an .ocx library and I want to use it".
With B4A and mainly with B4J can I make use of the library? How?
Thank you.

Usually an .ocx file is a Windows ActiveX control library. You cannot use it with B4A. I suppose it might be usable in B4J if you can find a way for Java to implement a COM (Component Object Model) interface to the library but I wouldn't hold out much hope for that.

Use a .OCX Control in Java

IS there a way to use a ocx control ( VB6) from Java?

Thanks folks, I'm going to ask the customer for more information, see if it's possible to get another way to access that device.

Check the manufacturer, maybe it has some java sdk

Silly questions:
How do I recognize a java sdk?
What is the extension of a java sdk?
How do I use it from B4J?
Thank you.

In this case the customer has bought that device "from the Chinese" and says that it has no brand and only brings an "ocx", I will ask him to send me pictures to see if I can find the manufacturer's website and they have more information.
Thanks again.

ocx is 20 year old technology, it is actively blocked by most browsers nowadays.

A java library would normally be delivered as a jar file (or many jar files).

Thanks folks, my customer is going to send me the fingerprint reader, when I get my hands on it I will investigate further.

Also from one of those links - the topic is 11 years old. Its probably cheaper/easier just to buy a new fingerprint reader TBH
