CouchDB connection

1. Log onto
Jelastic

2. Create environment with CouchDB database:
3. Check your email box for getting credentials to access CouchDB node:
4. Then create a file mydb.cfg in Config Manager (folder HOME). This file contains information on connecting to CouchDB. This info will be read by your application:
5. In this step you have to prepare part of java code that creates connection to your DB:
import com.fourspaces.couchdb.*;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;
import java.util.logging.Level;
import java.util.logging.Logger;

public class CouchdbConnector {

    public boolean createDatabase(String name) {
        try {
            //Read file mydb.cfg
            Properties prop = new Properties();
            prop.load(new FileInputStream(System.getProperty("user.home") + "/mydb.cfg"));
            
            //Getting info we need: host, port, username, password
            String host = prop.getProperty("host").toString();
            int port = Integer.parseInt(prop.getProperty("port").toString());           
            String username = prop.getProperty("username").toString();
            String password = prop.getProperty("password").toString();
            
            Session dbSession = new Session(host, port, username, password);
         
            dbSession.createDatabase(name);

            try {
                dbSession.getDatabase(name);
            } catch (Exception e) {
                return false;
            }            
        } catch (IOException ex) {
            Logger.getLogger(CouchdbConnector.class.getName()).log(Level.SEVERE, null, ex);
        }
        
        return true;
    }   
}

NOTE: you have to upload all libraries that CouchDB connection needs!

6. Deploy application : couchdb.war
7. Run deployed application and input database name you want to create:
Input database name:
8. Check CouchDB server if it contains "new" database:


- run CouchDB instance in browser;


- input credentials that you got on e-mail;


- check database presence.
