What do you name a Java package when it isn't a part of a top level domain?

I've read the syntax conventions for naming Java packages, and I know the general rule of thumb, but what if you've just started building your application, you haven't chosen a license, and it is a personal project? It doesn't make sense 开发者_C百科to throw in "com.mycompany" or "org.myorganization" if that is not the case. Does anyone have suggestions for this?

Many Java books and online examples just use the name of the book or project, i.e., ejb3inaction.* or tutorial.*.

I usually just go with something like lastname.firstname.<other packages>. The package name should just be unique, and the combination of your last name and first name is probably unique enough (if you have a common name, throw in a middle initial or a middle name or something like that).

Perhaps org.{myname} ?

I don't think it particularly matters for personal projects. In fact I've seen commercial (in-house) projects flout this rule and simply call their packages {servicename} or similar (which I don't particularly like). The packaging rules are designed to prevent name clahes when sharing code cross-enterprise (or organisation) and consequently for personal projects you can use most anything.

Java packages are just for namespacing. Call it whatever you want! Think of something that will be useful to you later on when you want to remember what this code was supposed to do.

how about org.{projectname}? Think about some open-source projects (e.g. org.hibernate, org.springframework and org.junit) ... did they start this way because it was the name of the website, or the name of the project itself?

Besides, re-factoring is so trivial these days, just name it whatever you want.

What about name.yourname.myproject or net.sf.myproject or com.googlecode.myproject or simply myproject.

As long as you don't make your code public, it's not that important actually (and you can easily refactor it later before releasing your code if you need to). Once people start using your code, it's another story...

In the case you might also think about sharing the project (making it an open-source project), to open an project entry, in that case you can use something like 'net.sf.{project-name}.*', be careful here, that the project-name, must be the unix name, of the project (at least then you follow the rules correctly :)

I generally use nl.myname.myapp for all personal projects. There is no rule against open sourcing something that uses your personal name. If you decide to make the project bigger and create a web site for it you can always rename the packages if you really want to.
