Sorry, I cannot copy the log but I see the below error message. Nothing else. "failed to process session due to java.lang.NoClassDefFoundError: org/apache/commons/collections/map/ListOrderedMap: java lang.NoClassFoundError: org/apache/commons/collections/map/ListOrderedMap" .

My flow transforms data in JSON format to XML format using a Groovy script in ExecuteScript processor. The script imports net.sf.json.JSON, net.sf.json.JSONSerializer and net.sf.json.xml.XMLSerializer. I included all the jars below but I get an error, "Failed to process session due to java.lang.NoClassDefFoundError:Could not initialize class net.sf.json.JsonConfig". I tried with different versions of the jar but an error still persists. Please suggest what's going wrong. Thanks.

Thanks for explaining the missing bits @Shishir Saxena, this is very valuable information. I moved the input/output ports to root level processing group and I could transfer data from A to B.

Thanks for the quick answer @Andrew Grande. Used 8443 port because we have very limited ports available to use and for now we are testing non-secured instance. Thanks for the suggestion, shall follow best practices. Removed nifi.remote.* properties on the A side. Removed input.socket.port on the B side. http://B-hostname:8080/nifi/ is the URL and HTTP is the transport protocol used in RPG setup. I am not much into this, may I please know how to make sure input/output ports added the root top-level processing group on B? I did the suggested changes but couldn't see the ports in RPG after initial setup.

I am trying to push data from NiFi instance (A) to another NiFi instance (B) with below configurations - site to site properties in A nifi.remote.input.host=FQDN of B nifi.remote.input.secure=false nifi.remote.input.socket.port=8443 nifi.remote.input.http.enabled=true nifi.remote.input.http.transaction.ttl=30 sec site to site properties in B nifi.remote.input.host=FQDN of A nifi.remote.input.secure=false nifi.remote.input.socket.port=8443 nifi.remote.input.http.enabled=true nifi.remote.input.http.transaction.ttl=30 sec I configured RPG, could browse to the remote host using 'Go To' but couldn't see any ports in Remote Ports.
