FLINK Stream API socketTextStream(hostname, port) method acts as Client. that is we need to send the continuous stream on the port and " socketTextStream (hostname, port)" method will read the incoming stream.
But my requirement is like, I want to use FLINK as a server and looking for an API that can listen from a port. Can any one has the FLINK stream API? that will solve my problem. Thanks in advance !!!

There's no support for this built into Flink, but if you really wanted to you could build a server into a flatmap operator, or a ProcessFunction, or implement a custom Sink.
However, this doesn't seem like a good way to build a robust system (it won't be easy to make this fault tolerant, or to manage redeployments without data loss). Why not stream the results from Flink into something like a Kafka topic, and attach the other clients there?
