It might seem like a vague definition, but I want to tell you that this is a very productive Java library that can solve many of typical IT problems! You can think of it as a very light weight ESB framework with "batteries" included. In every jobs I've been to so far, folks are writing their own solutions in one way or another to solve many common problems (or they would buy some very expensive enterprisy ESB servers that takes months and months to learn, config, and maintain). Things that we commonly solve are integration (glue) code of existing business services together, process data in a certain workflow manner, or move and transform data from one place to another etc.

The Java™ Platform, Standard Edition (Java SE™) is used for a wide variety of applications, from small applets on desktops to web services on large servers.

In support of this diverse range of deployments, the Java HotSpot™ virtual machine implementation (Java HotSpot™ VM) provides multiple garbage collectors, each designed to satisfy different requirements. This is an important part of meeting the demands of both large and small applications. However, users, developers and administrators that need high performance are burdened with the extra step of selecting the garbage collector that best meets their needs.

A significant step toward removing this burden was made in J2SE™ 5.0: the garbage collector is selected based on the class of the machine on which the application is run.

Hadoop. Tropical Software Observations: Testing Grails Service class. Testing Grails service classes is easy if the service does not call any domain persistence methods.

Meaning if your service class does cause some domain object to persist to database, it's going to be painful to try to mock the calls and check the result. And I'm not even sure if it's worth it to try. The problem is that grails-testing newbies like me will want to try to do unit testing for services. In short, don't do that unless your service classes are simple and easy. Koding. CodePen - Front End Developer Playground & Code Editor in the Browser.
