Problems connecting monitoring tool to cluster

[Lappo]

I wrote a very basic web application just to test hazelcast (1.9.2)
I started two tomcat instances on my local machine (tomcat 6.0.29)
containing my web application.
The clustering works great.
I tried to install the monitoring tool on a tomcat instance, but by
connecting to the cluster (dev, dev-pass, 192.168.1.11:5701) I get
following error on a node of the cluster:

on the monitoring tool side I get following error:

I can't figure out how to solve this problem...

Hi,

Are you using the 1.9.2 monitor war file?

Hi,
I found the problem:
my web application is a maven project and is using the last available
hazelcast artifact (1.9.1-RC2)
the monitoring tool was part of the hazelcast 1.9.2
I downgraded the monitoring tool to version 1.9.1 and the problem
disappeared!
thank you very much for answer!
nice tool.
Lappo
