In an ideal world, sun would prefer that when upgrading to a new version of a specification that that upgrade path is as easy as possible and that the new version is fully backwards compatible.
By and large, except for minor discrepancies, that is the case, at least for the j2se. One of the reasons why they do not want to change the name of a jar between versions is because then it would make upgrading a lot harder because you would have to change all the places where the jar names are specified (in the class paths for instance). Maven, fortunately, handles the versioning for you (it's not so difficult to go to a new version of a jar with maven). I guess it's also because, as has been mentioned, the licensing of java does not allow it to be placed on a repository library and thus the need for versioning is not so fundamentally important. It is essential that versioning is incorporated into a repository of jars because many people might be using it and therefore require all the different versions of the jars. Besides, when you upgrade your version of java or j2ee, it's not simply a case of changing the jars, it's got more implications than just that. -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Mutonho Sent: 13 April 2006 09:26 AM To: [email protected] Subject: [CTJUG Forum] Re: Question about Sun jars On 4/13/06, Clint Lewis <[EMAIL PROTECTED]> wrote: > > Hi, > > On the same issue if you take a look at > http://www.ibiblio.org/maven2/javax/j2ee/j2ee/1.4/ you will see that > they version J2EE... since we all now that J2EE is on version 1.4. Well , but still the jars that you get from Sun do not have version numbers and that's what my question is about. Read our disclaimer at: http://www.picknpay.co.za/pnp/view/pnp/en/page5093?
