vi producer.go 

Update variables according to your OCI configuration file and OCI Streaming Service streamOCID and Endpoint:

const ociMessageEndpoint = "https://cell-1.streaming.eu-frankfurt-1.oci.oraclecloud.com"
const ociStreamOcid = "ocid1.stream.oc1.eu-frankfurt-1.amaaaaa..."
const ociConfigFilePath = "/home/fernando_h/.oci/config"
const ociProfileName = "DEFAULT"

You might need to update dependencies in mod with below command :

go get -d github.com/oracle/oci-go-sdk/v49@latest

Then run the application:

go run .

You sould be able to see a bunch of new messages being sent to OCI Streaming.

Example from documentation https://docs.oracle.com/en-us/iaas/Content/Streaming/Tasks/streaming-quickstart-oci-sdk-for-java.htm#java-sdk-streaming-quickstart https://github.com/oracle/oci-java-sdk

mvn -B archetype:generate -DgroupId=com.oci.stream -DartifactId=Consumer -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4
cd Consumer
vi pom.xml

Add dependencies to pom file:

<dependencies>
    <dependency>
      <groupId>com.oracle.oci.sdk</groupId>
      <artifactId>oci-java-sdk-common</artifactId>
      <version>1.33.2</version>
    </dependency>
    <dependency>
      <groupId>com.oracle.oci.sdk</groupId>
      <artifactId>oci-java-sdk-streaming</artifactId>
      <version>1.33.2</version>
    </dependency>
  </dependencies>

Copy class Consumer.Java to mvn project location:

cp ../Consumer.java src/main/java/com/oci/stream/

You sould need to update de oci configuration file and the oci stream id and message endpoint:

        final String configurationFilePath = "/home/fernando_h/.oci/config";
        final String profile = "DEFAULT";
        final String ociStreamOcid = "ocid1.stream.oc1.eu-frankfurt-1.amaaaaaaue...";
        final String ociMessageEndpoint = "https://cell-1.streaming.eu-frankfurt-1.oci.oraclecloud.com";

Open Consumer.java and update OCI configuration:

vi src/main/java/com/oci/stream/Consumer.java

Finally, run the application with maven and see the messages previously produced with the Go producer being processed:

mvn install exec:java -Dexec.mainClass=com.oci.stream.Consumer

You should be able to see the output with the captured messages
