Subject WARNING [Tribes-Task-Receiver-3] org.apache.catalina.ha.session.ClusterSessionListener.messageReceived Context manager doesn't exist
Date Tue, 08 Sep 2015 11:28:32 GMT
Hi all,

I tried to create a cluster two hosts. At which I did not succeeded
completely.

OS(both systems):
SMP Debian 3.16.7

java (both systems):
martijn@bloemkool:~/apache-tomcat-8.0.26/conf$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

Tomcat (both systems):
Apache Tomcat/8.0.26

I installed 2 tomcat's
One on host bloemkool.bos.

I see some communication between the nodes, which indicates to me that a
lot is going OK.

However, if I deploy a webapp on one host, I'll get a warning on the
other host and the webapp will not be deployed:

Logging from the host on which I deploy:

I'm a bit out of options. Google did not came up with a solution (at
least not for me).

Can someone point me in the right direction (or is there a solution
available?).

Any pointers or advice are greatly appreciated.

Martijn
