Overview

This is a sample gRPC Java based implementation of a HelloWorld program. This is implemented basically to demonstrate the WSO2 Microgateway's gRPC API Concept.

gRPC client is implemented in such a way that it accepts an api key token. Hence "api_key" header is added to the RPC call.

gRPC server do not perform any authentication.

How to execute

• Install Java and Maven and update the PATH variables accordingly.

• Build the project using Maven.

mvn clean install

• To run the gRPC server,

java -jar serverImpl/target/serverImpl-1.0-SNAPSHOT.jar <port>

• To run the gRPC client,

java -jar clientImpl/target/clientImpl-1.0-SNAPSHOT.jar <input-text> <api_key_token> <port>
