MDIFramework provides a ready-to-use architecture to ease the creation MDI-style applications in Java. It takes care of the overall architecture of the main window of the application, with a tabbed architecture, the presence of an HTML printable message area, and so on. It provides a generic API to manage lengthy actions, keeping the interface responsive, and taking care that actions are performed one at a time, without having to bother about it. It can add metadata to already opened files. It manages loading and unloading of external plugins at runtime.
VectorGraphics2D can export Java painting operations to Encapsulated PostScript (EPS), Scalable Vector Graphics (SVG), or Portable Document Format (PDF) files. It supports the rendering of all geometric shapes provided by the Java language. More advanced features like transparency or clipping paths can be used as well. It has a very small footprint and can be easily used as a replacement for Java's java.awt.Graphics2D class.
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.
SDMetrics Core is a Java library to calculate metrics of structural design properties such as coupling, size, and complexity for UML designs. It also checks design rules to automatically detect incomplete or incorrect design, and adherence to style guidelines such as circular dependencies or naming conventions. The library provides an XMI parser for import of XMI 1.x files with UML1.3/1.4 models, and XMI 2.0/2.1 files with UML 2.x models. Design metrics, rules, and XMI import are highly customizable.
Simple Java Mail aims to be the simplest to use lightweight mailing framework for Java, while being able to send complex email messages including attachments and embedded images. The Simple Java Mail framework essentially is a wrapper around the JavaMail SMTP mailing API that allows users to define email messages on a high abstraction level without having to deal with terminology such as "multipart" and "mimemessage".
jRapidRPC is a Java RPC library that allows you to create client-server applications that talk in objects. It is small, fast, and extensible. Its smallness helps you learn how to use the library quickly. jRapidRPC is fast due to its compact size and lack of complexity. Also, it uses the ProtoStuff serializer by default. jRapidRPC's extensibility allows you to can write a new client-server or a new serializer.
