Java is considered as an platform independent development and application, or better known as WORA, which stand for Write Once, Run Anywhere. You can always develope your application on Windows, but run it on Linux, or maybe Solaris, or maybe AIX. As long as you have the correct version of JDK or JRE for that particular platform, any java application will run.
But yet, 1 basic rule for java development, never ever deploy to a platform that you never test your application on. In other words, if your production server is running on Linux, please test your application on Linux environment before moving into the production.
Why did I say so? Because, there are many different mechanism in different platform. For example, if you use your application to execute a Windows command, most probably you won't find that command in Linux. But the worse case is that you might not aware of that when writting the codes. Another fine example is the real path that you might use. You may use "\" in writting real path codes in Windows, but then, unix environment does not recognise this character as a path.
So, remember to test fully on the actual, or more to actual environment before planning moving into production.
