From an external Java program, I want to send some XML to NiFi.
Here is my requirement:
From an external Java program, I want to send some XML to NiFi. Whenever
NiFi gets that XML, it does something.
1) What NiFi process I need to use to get this request from Java.
So far, I learned how to start/stop the flow and process from Java. I am
using NiFi 1.0.
2) I have tried to use HandleHttpRequest, but it is showing this Error:
HTTP Context Map' validated against 'StandardHttpContextMap' is invalid
because Controller Service
StandardHttpContextMap[id=2c5ddba9-ed6a-4c5f-d911-bfd6468bf19b] is disabled.
Thanks
Srini

StandardSSLContextService is necessary if you want the incoming HTTP connections to be over HTTPS (i.e. encrypted and secured). If you want this feature, you will need to configure an SSL controller service with your keystore and truststore files and the appropriate passwords.

Thanks Andy, Now StandardHttpContextMap is good.
I still have this error with HandleHttpRequest. StandardSSLContextService is
invalid:
"'SSL Context Service' validated against
'c6b03cd2-69af-4a04-3ded-b3a1d39c07a6' is invalid because Invalid Controller
Service: c6b03cd2-69af-4a04-3ded-b3a1d39c07a6 is not a valid Controller
Service Identifier or does not reference the correct type of Controller
Service"

Hi Srini,
To move data from an external Java process to NiFi, there are a number of possible solutions. If the data can be serialized to disk, simply writing it to a file in the Java process and using the GetFile processor in NiFi is the easiest way.
If you want to use HandleHTTPRequest, you will need to enable the StandardHttpContextMap controller service [1], as indicated by the error message you posted. It appears you have already created it, but you have not yet enabled it. After entering the Controller Services management dialog, there should be a lightning bolt icon on the right that you can click to enable this controller service.
