Exception in thread "main" java.lang.NoClassDefFoundError

Exception in thread "main" java.lang.NoClassDefFoundError /opt/red5/server/Standalone

I get this error when I first run the program's red5.sh file
Other people say that they have had this problem, but not with this software, so I was wondering if you could get a fix for me.

thanks

Did you use the Red5 tarball?
Did you compile Red5 before running red5.sh?
Which version of Java are you using?

Closing as no feedback was given. I'm assuming you are trying to execute Red5 from the source distribution without compiling it first. Feel free to reopen with more details if I'm wrong ;)

I am having the same exact problem. To answer you questions - I used Red5 tarball. I compiled Red5 using "ant". Jave version 1.5

Could you please help?

thanks

This tutorial ( http://www.red5tutorials.net/index.php/Howtos:General) tells that to have a stand-alone server you have to type 'ant server'. I think most people, myself included, followed these instructions tightly. When I compiled with the 'ant server' command I got the NoClassDefFoundError. I recompiled with the 'ant' command first and I could run the red5.sh script correctly.
