driver.findElement(By.id("password_h")).sendKeys((CharSequence[]) Sheet.getCell(1, i));
driver.findElement(By.id("health_btn")).click();

The problem is that you try to instantiate the FileInputStream with a com.gargoylesoftware.htmlunit.javascript.host.file.File which is indeed undefined. If you need that import then you should change the problematic line to

FileInputStream file = new FileInputStream (new java.io.File("C:\\Documents and Settings\\Deepa\\Desktop\\testdata.xls"));
