We used an external library, specifically jmf.jar (Java Media Framework), for our java application which relies on images captured from the webcam. However, when we tried to package the application into a jar file, the application runs but once we try to access/open the webcam nothing happens.
We are using Eclipse and we used its export feature to create the jar file.
Does anybody know how to solve this?
Did you think to include jmf in the manifest of your jar ? See this link for more explanations here
