Red 5 media server version 1.0 finding correct Java version

Question

I have installed Red 5 media server version 1.0 rc2 to a windows 2008 server, 64 bit.

I am trying to start the Red 5 service, that fails and the log is as below:

STATUS | wrapper  | 2014/02/13 15:19:16 | --> Wrapper Started as Service

This seems from googling something to do with java version so I uninstalled the currect JDK and reinstalled JDK 6 Update 18 as described here: http://red5guide.com/install_jdk_jre_for_red5.html

I have set the windows PATH environment variable to C:\Program Files (x86)\Java\jre6\bin;C:\Program Files (x86)\Java\jdk1.6.0_18\bin

When i run java -version I get:

java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode, sharing)

However I still can't start the Red 5 service with the same log given as shown above.

Any ideas what could be wrong?

Answer 1

Unsupported major.minor version 51.0 indicates that the compiled version should be using JDK version 7. Install that version and run it again.
