How to map xpath of web element in its actual class? - selenium

Question

I am creating a framework in selenium from scratch where i am scripting below scenarios:
1.Login in to https://www.yahoomail.com
2.entering username
3.entering password
4.click on Sign-In
5.click on Compose button
6.Enter Email ID, Subject and Message body.
Below is the code script i have written for above scenario:
WebDriver oYahoo = new FirefoxDriver();
oYahoo.get("http://www.yahoomail.com/");
oYahoo.manage().window().maximize();
oYahoo.findElement(By.xpath(".//*[#id='login-username']")).sendKeys("abcdefasdf#yahoo.com");
oYahoo.findElement(By.xpath(".//*[#id='login-passwd']")).sendKeys("sfgas234#123");
oYahoo.findElement(By.xpath(".//*[#id='login-signin']")).click();
oYahoo.findElement(By.xpath(".//*[#id='Compose']/button")).click();
oYahoo.findElement(By.xpath(".//*[#id='yui_3_16_0_1_1448364357109_2222']")).sendKeys("abcdefgh#gmail.com");
oYahoo.findElement(By.xpath(".//*[#id='subject-field']")).sendKeys("Hi This is my first automated mail");
oYahoo.findElement(By.xpath(".//*[#id='yui_3_16_0_1_1448364357109_1966']")).sendKeys("Hi This is my first automated mail");
oYahoo.findElement(By.xpath(".//*[#id='yui_3_16_0_1_1448364357109_2465']")).click();
oYahoo.quit();
Scripts fine till it clicks on "Compose" button, Once i get Mail editor, Script does not enters email-ID,Subject, and Message body.
What other action i should perform to achieve the same so that script will enter these parameters and can send a mail to particular user.
Do we need to create some class which will maps the locators to "compose-Email" screen?
If yes, how we can map/assign x-path to particular web element of Compose-Email page.
Thanks in Advance.

Well you should try by using the xpath and enter the required text. Something like this (it works for me)-
oYahoo.findElement(By.xpath(".//*[#id='to-field']")).sendKeys("xxxx#xxx.com");
oYahoo.findElement(By.xpath(".//*[#id='subject-field']")).sendKeys("My first automated email");
oYahoo.findElement(By.id("rtetext")).sendKeys("Hello....Hi....This is my first automated email");
