Gentlemen, You all are an absolute dream team. And the product you produce is superb.
It works now! After I saw Maxim's message about the flowoutTimeout (that was a verbatim copy from Alvaro's manual), I just removed that Bean property, restarted the kurento and the tomcat, and visited my website at port 5443, and... The 404 error was all gone! I was able to login on my computer and, separately, on my cell phone. Now, both cameras were visible on both devices, and the sound was going through, as well. So, Alvaro's document about SSL helped me to also solve the problem of not working cameras and microphones. It is all good now. Should be clear sailing from here on. I did have a couple of operational questions, but perhaps Openmeetings help-files would have the answers; so, if you all have more urgent questions to answer, no worries. The questions are: 1) is it possible to add users from a file that contains their information, rather than one-by-one. If I have 50 students in class, or more, it would be more efficient to use a file. I do *not* want to have self-registration, since that may result in a number of people "from the street", which might get me in trouble with the administration. 2) Is it possible to have a setting whereby each user has the camera automatically turned on when joining a meeting room and the microphone turned off? Furthermore, it would be excellent if I can restrict their ability to turn off the camera (the microphone can be free under their control, so that they can ask questions). Because, otherwise, they may turn the camera off, and I do not have a way to see if they are following the class or not. 3) Even less pressing question. Whether there is a way to integrate users between Openmeetings and B2Evolution.... Recently, I have been using B2Evolution to run my websites. All my students have accounts on the B2E site relevant to their specific classes (each class has its own DB on mariadb). It would be superb to transfer those users to Openmeetings, without having to register them separately. I guess this should be done somehow via mariadb databases, between the DB used by Openmeetings and the DB used by B2E... Thank you very much for your all's prompt and helpful responses with solving the 404 error. Honestly, I did not dare to hope that we would have that resolved before the sun rises this morning, but we did! Have a good the rest of the day and stay safe. Robert.
