java - I am getting the error when I run applet in HTML page even after I have signed all the jar files -
both videoplayer , html contains external jar files in library jna-3.5.2.jar,platform-3.5.2.jar , vlcj-2.4.1.jar. both videoplayer , html page in different projects in netbeans , have included external jar files mentioned above in both projects.
this code of videoplayer class.
