Could not initialize class org.red5.server.net.rtmp.RTMPHandshake

[smguenther]

Hello,

we have an OpenMeetings installation 1.6.2.r3675, which suddenly
doesn't display the login screen anymore.

During the start of red5 there aren't any error messages. But as soon
as we call IP:5080/openmeetings we get the following errors messages
in red5.log:

Does anyone know what might cause this problem?

Thanks for any hints/suggestions,

If you restart the service, is the error gone?
How many connections did the server process before the Error came up?

well, when I restart the service, it will come up again, but as soon
as I call the URL, red5.log contains the error.

It is always the first connection.

are you sure that there are no other exception log statements in the logfile?

Maybe you like to have a look at the logs?

Your server did not even startup yet. You try to connect to the server before it even has completed the startup.
The log message when the service startup is completed look like:

DEBUG 04-27 10:26:40.640 EmoticonsManager.java 4281 53
org.openmeetings.app.remo
te.red5.EmoticonsManager [Launcher:/openmeetings] - ##### loadEmot
completed

I don't know why the process hangs in your case, maybe the connection to the database is still trying to connect to and is waiting for a timeout.

I solved it!

The java version was updated from /usr/lib/jvm/java-6-sun-1.6.0.24 to /usr/lib/jvm/java-6-sun-1.6.0.26

JAVA_HOME in /etc/profile and /etc/init.d/red5 still contained the old directory.

Thanks for your help,

Stefan
