In practice, this requirement means that even after removing the reference implementation concept, GlassFish is still one the few implementations that can be used to ratify specifications. It also puts implementations that don’t include optional features at a disadvantage because they can’t be used to ratify the specification. This requirement puts a burden on the implementation because it cannot drop the feature if it’s not needed. The implementation that’s used to ratify the specification must implement all optional features. However, there is an exception to this rule. The Digest authentication mechanism in Jakarta Servlet is an example of such a feature. Jakarta EE includes a number of optional features that are specified, but don’t need to be implemented for a product to be deemed compatible with the specification. Addressing the Optional Features Limitation The work on the porting kit and reference implementation are ongoing, and may not be complete when Jakarta EE 10 is released. At some point, it should be possible to use any compatible implementation, or perhaps the entire concept of interoperability testing should be removed. Currently, GlassFish is always the reference implementation in the TCK. The full TCK also includes tests for communications between application servers, which means it supports the concept of a reference implementation and a vendor implementation. For example, the TCK allows developers to redefine a URL using a kind of factory. It also provides implementations of various TCK interfaces that developers can include in their code. ![]() This porting kit provides resources such as the above-mentioned files to deploy test archives. GlassFish is currently supported out of the box, while other implementations need a porting kit. The dependency was removed by turning the TCK into a regular Maven project and referencing all of the various Jakarta EE APIs using their official Maven coordinates. This was always a less-than-optimal dependency that was conceived out of convenience rather than any solid engineering principles. Specifically, the dependency on GlassFish for building the TCK has been almost entirely removed. For the Jakarta EE 10 version of the TCK, the team has been working incredibly hard to remove these dependencies, and has made considerable progress. The Jakarta EE TCK has GlassFish dependencies in several places and includes many files that are specific to GlassFish, such as files that tell the TCK how to deploy test archives. It’s now a Jakarta EE implementation at the same level as all other implementations. This change means Eclipse GlassFish no longer has special standing in the specification process or any special designation. With the compatible implementation concept, any implementation can be used to ratify a new specification release. ![]() When GlassFish moved to the Eclipse Foundation and Java EE became Jakarta EE, the Eclipse Foundation Specification Process replaced the concept of a reference implementation with the concept of a compatible implementation. Among other things, that meant an update to a Java EE specification could not be officially released until GlassFish implemented it and passed the associated Technology Compatibility Kit (TCK) tests. GlassFish was the reference implementation for Java EE for many years. From Reference Implementation to Compatible Implementation Today, the GlassFish technology is flourishing at the Eclipse Foundation, and is being updated to strengthen its merits as an application server. Indirectly, GlassFish can be traced all the way back to the Kiva Enterprise Server from 1996. The GlassFish technology can be directly traced back to the Sun ONE Application Server 7 (S1AS 7), which was Sun Microsystem’s primary server product in 2003. ![]() In a maven based project you can use the following: įor Jersey 2.x you don't need to setup anything in your web.xml, it is sufficient to supply a class similar to this: import .rs.The Eclipse GlassFish application server is a compatible product for every Jakarta EE release, and it has very deep roots in the Java world. ![]() If you instead want to use Jersey 2.x then you'll have to supply the Jersey 2.x libs. Indicates that you try to use the Jersey 2.x servlet, but you are supplying the Jersey 1.x libs.įor Jersey 1.x you have to do it like this: Ĭom.servlet.ServletContainerįor more information check the Jersey 1.x documentation.
