        config.setAuthEndpoint(enterpriseEnvironment);
        config.setUsername(username);
        config.setPassword(password);
        try {
            connection = Connector.newConnection(config);
        } catch (ConnectionException e) {
            Logger logger = Logger.getLogger(this.getClass());
            logger.error("Unable to authenticate as '" + username + "'", e);

StringBuilder instead of String

Use StringBuilder  instead of String while concatenating a String.

 StringBuilder sb = new StringBuilder();
sb.append("***************************************************\n");                sb.append("XMLName: ").append(obj.getXmlName()).append("\n");             
sb.append("DirName: ").append(obj.getDirectoryName()).append("\n");     
sb.append("Suffix: ").append(obj.getSuffix()).append("\n");                  sb.append("***************************************************\n");
System.out.println(sb.toString());

when we use String it will create a object for every concatenation.

String str="XMLName: " +obj.getXmlName()+;
