Open a new terminal window, copy Connection String from Keys tab of the created Azure Web PubSub service, run the below command with the <connection-string> replaced by your Connection String:

cd logstream-webserver
mvn compile & mvn package & mvn exec:java -Dexec.mainClass="com.webpubsub.tutorial.App" -Dexec.cleanupDaemonThreads=false -Dexec.args="'<connection_string>'"

cd logstream-streaming
mvn compile & mvn package & mvn exec:java -Dexec.mainClass="com.webpubsub.quickstart.App" -Dexec.cleanupDaemonThreads=false
