WSO2 ESB Axis2 Service throwing Host name verification failed for host

Question

I have created an AXIS service which connects to WSO2 Identity Server and validates a token. When I deploy this axis service on WSO2 App Server, I get the correct response. Where as when I deploy it on WSO2 ESB, I get the following error

org.apache.axis2.AxisFault: The input stream for an incoming message is null.

Answer 1

Set the parameter HostnameVerifier to AllowAll for transportSender in the Axis2 configuration (axis2.xml).

<transportSender name="https" class="org.apache.synapse.transport.passthru.PassThroughHttpSSLSender">
   <!--...-->
   <!--supports Strict|AllowAll|DefaultAndLocalhost or the default if none specified -->
   <parameter name="HostnameVerifier">AllowAll</parameter>
   <!--supports Strict|AllowAll|DefaultAndLocalhost or the default if none specified -->
</transportSender>
