Example text

Writing database access code isn’t much fun, so persistence providers supply a nicer set of interfaces to manage the interaction between the application code and the database. This is a business application, and so transactions are usually involved—either buying and selling of goods and services, or some other business agreements. To ensure these “real” transactions proceed smoothly and consistently, even in the event of a communications problem, software transactions are used. With all this going on, these enterprise applications are starting to get pretty complex.

If you don’t specify a range, then your import runs to infinity, meaning that your bundle expects to be able to use any version of the package, regardless of how it changes! It’s good practice to always specify a range, using square brackets for inclusive or parentheses for exclusive versions. 1 would be compatible up to, but not including, version 2. Coexistence of implementations The most significant benefit provided by versioning is that it allows different versions of the same module or package to coexist in the same system.

One application will run with the version it expects, and the other won’t. In some cases, the “losing” application may terminate with a NoSuchMethodError because it invokes methods that no longer exist. In other, worse cases, there will be no obvious exceptions but the application won’t behave correctly. These issues are incredibly unpleasant and in Java have been given the rather self-explanatory name classpath hell. Although classpath hell is a bad problem in core Java, it’s even more pernicious in the enterprise Java domain.
