I want to create a java application using SymmetricDS embedded. As there is no documentation on how to perform this, i want a sample example or a documentation . Please help me I'm stuck.

Answer 1

this an example how run the Symmetric engine server in embedded mode , and it works perfectley for me :

public class ClientNode {
	private ClientSymmetricEngine cEngine;
	private File propFile;


	public ClientNode(File file) throws FileNotFoundException, IOException {
		propFile = file;
		Properties propertiesFile = new Properties();
		propertiesFile.load(new FileReader(propFile));
		cEngine = new ClientSymmetricEngine(propertiesFile, true);
		getcEngine().openRegistration("client", "001");// client is the name of the node group and 001 is the ID
		getcEngine().setup();
		getcEngine().start();
	}

	public ClientSymmetricEngine getcEngine() {
		return cEngine;
	}

	public void setcEngine(ClientSymmetricEngine cEngine) {
		this.cEngine = cEngine;
	}
}

Main class :

public static void main(String[] args) {
	
				
	try {
		new ClientNode(new File("client.properties"));
		SymmetricWebServer node = new SymmetricWebServer("master.properties");
		node.setWebAppDir("Web"); 
		node.setJoin(false);
		node.start();
		// this will stop the node
		//node.stop();
		}catch (Exception e) {
			e.printStackTrace();
		}
				
	}

Properties files :

client.properties :

external.id=001
engine.name=client-001
sync.url=http\://localhost\:31415/sync/client-001
group.id=client
db.url=jdbc\:mysql\://localhost/easyexchangedb_slave
db.driver=com.mysql.jdbc.Driver
db.user=root
registration.url=http\://localhost\:31415/sync/server

master.properties :

external.id=server
engine.name=server
sync.url=http\://localhost\:31415/sync/server
group.id=server
