There has some issue with spaces in URL. As you have to remove spaces through encode url like below before passing into connection.

String  encodedURL=java.net.URLEncoder.encode(url,"UTF-8");
//Than pass it connection as below
DriverManager.getConnection(encodedURL, databaseUserName, databasePassword)
