Why Run Java EE Applications in the Cloud with the Payara Platform datasheet.

A blog about Java, Spring, Hibernate, Programming, Algorithms, Data Structure, SQL, Linux, Database, JavaScript, and my personal experience.

I’ve been programming in Java for over half a decade, and thought I knew how overloading and overriding worked. It was only once I started thinking of and writing up the following corner case…

A new JEP draft proposes to improve G1 garbage collector performance when concurrent refinement is disabled by introducing a simplified post-write barrier.

The Java platform has become one of the most widely used platforms, with a huge ecosystem in the world of technology. Java lets developers create applications for several platforms, such as Windows, Linux, embedded systems, and mobile. Java also has received criticisms, such as: Java is fat; Java takes a lot of memory; Java is verbose. But, …

The advent of blockchain shows we have to change how we think about development and how typical roles are changing, overlapping and becoming more fluid.

It should go without saying that in any piece of development testing is important. While unit testing can (and should) be used to test the individual components which make up a piece of software, there always comes a point where the software has to have a set of integration tests ran. Mocking of components can allow code to be tested in isolation, however if overdone all that has been achieved is testing the mocks. Integration tests should be ran in as close to a realistic deployment as possible, as the more differences which exist between the test environment and a production deployment, the more scope there is for bugs to slip through. Testing of a deployed component makes getting code coverage metrics more difficult than in regular unit tests, but is still possible. Frameworks such as the Jersey Test Framework can allow unit testing of JAX-RS REST endpoints that have been created, but this is not equivalent to a truly deployed component and so features such as CDI and the MicroProfile features I am looking into cannot easily be tested this way. While not related to MicroProfile, testing of DAO code is another area which has traditionally been an integration approach, as it required a running database server, but there are now libraries available that can allow this to be tested as unit tests.

A Java cloud IDE can prove largely beneficial for developers. But the choice isn’t a simple one. Explore these four options for cloud-based development, and pay special attention to cost and flexibility before you make a decision.
