I am following the instructions of https://cwiki.apache.org/confluence/display/OPENMEETINGS/Tutorials+for+installing+OpenMeetings+and+Tools
I completed all the 19 steps now at Step 20 and trying to run the script "red5-debug.bat" but viewing the error like: "Listening for transport dt_socket at address: 8787 Error: Could not find or load main class org.red5.server.bootstrap" What's it and how to resolve?
