Hi.

When testing samples\json (with Tomcat 9.0.10 and Axis2 1.7.8), there's
following error in Tomcat's log file catalina-daemon.out


[ERROR] The endpoint reference (EPR) for the Operation not found is
/axis2/services/JsonService and the WSA Action = null. If this EPR was
previously reachable, please contact the server administrator.
org.apache.axis2.AxisFault: The endpoint reference (EPR) for the
Operation not found is /axis2/services/JsonService and the WSA Action =

administrator.
