AppDynamics an application performance management solution for mission-critical Java applications. It can organize user requests and business transactions, monitor business transaction health, identify and diagnose slow requests, identify and diagnose errors, and drill down. It is built from the ground up for highly distributed service-oriented environments. It has fast root cause diagnostics at the method/class level, but creates no more than 2% overhead, even in high-volume production deployments. It can not only manage applications, but dynamically scale them in cloud and virtual environments.
Resty is a small, convenient API to talk to RESTful services from Java. Its focus is on simplicity and ease-of-use, often requiring only two lines of code to access RESTful Web services. It lets you use much less code than URLConnection, it's simpler than Apache HTTP client, and it's more reliable than Jersey client.
CRest (Client REST) is a lightweight library that simplifies the integration of third party RESTful services into Java applications. CRest is mainly annotation-driven, allowing the developer to focus on the essential aspects of the integration of a REST service, such as the definition of the Java interface that maps the remote REST methods and the data model the interface will deal with. The rest is achieved by annotating a plain Java interface with the relevant information such as the service end-point, the desired timeouts, URL formats, etc. CRest will handle everything else, including HTTP request generation, auto marshalling of the response, and more.
lzo-java is a Java port of liblzo2, a portable lossless data compression library. It provides block and stream interfaces to the lzo1x, lzo1y, and lzo1z algorithms, and it can handle raw and lzop file formats. The implementation is designed for high performance reading and writing, and simplicity of integration. It is integrated with Hadoop for high performance, and transparent compression is included.
ck-jsf-editor is an editor component for JSF 2 that uses the popular browser editor, CKEditor. Most JSF editors lack the functionality of CKEditor and require using an entire component library. ck-jsf-editor is a standalone rich text editor component that requires no real configuration or setup. The ck-jsf-editor.jar file can just be dropped into your project and used in your JSF pages.
Funcito is a Java library which simplifies access to your favorite functional programming APIs by wrapping Java methods as the function-type objects defined in those libraries. Rather than creating another functional programming API, Funcito makes it easy to define function-type objects which wrap existing methods. As a result, your code has less noise and clutter of anonymous inner classes, annotations, etc. Your code remains safe for automated refactoring, since there are no String-based reflection or forced naming conventions. The supported frameworks are Google Guava, Jedi, Functional Java, Play! Framework 2, collections-generic, and Netflix RxJava.
Unlike other Java to Objective-C solutions, Java-Objective-C Bridge doesn't require any code generation of class stubs. It allows you to use any Objective-C libraries and frameworks from Java without having to write any native code. In addition to being able to use Objective-C objects, it allows you to pass Java objects to the objective-c runtime as delegates, so that you can write an entire Cocoa application in Java. The bridge provides 3 levels of abstraction. At the lowest level, it provides wrappers around the Objective-C runtime functions. At a slightly higher level of abstraction, it provides a procedural API to send messages to the Objective-C runtime. At the highest level of abstraction, it provides a Proxy class that serves as a wrapper around any Objective-C object that allows you to work with it in Java almost the same as if you were in Objective-C.
JCabi is a collection of small, useful Java components. It includes a convenient static wrapper around SLF4J, a Sonatype Aether adapter, an Amazon Elastic Beanstalk Maven plugin for seamless deployment of artifacts, a Heroku Maven plugin, a Maven Log to SLF4J binding, and a few others.
