    eBus

    Publish/Subscribe, Request/Reply Messaging API for Java.

    A Java middleware API supporting broker-less, type+topic-based publish/subscribe and request/reply messaging for both intra- and inter-application, object-level communication. Broker-less: messages are transmitted directly between eBus applications. There is no message broker (i.e. server) in between. Type+topic addressing: eBus clients subscribe to a message class (type) and message topic, providing stronger typing than just topic-based subscriptions. Object-level communication: eBus delivers messages directly to client objects, not to a client process.

    You know the component scanning feature of Spring? You'll love this: component scanning as easy as select(javaClasses()).from("your.package").returning(allAnnotatedWith(YourAnnotation.class)). Can support any language running on the JVM. ---------- eXtcos is now also available from Maven Central. To include it into your Maven project just add this dependency: groupId: net.sf.extcos artifactId: extcos version: 0.4b Unfortunately Sourceforge doesn't support XML snippets in the description, so you'll have to build it yourself if needed. ----------- To read the user manual click the website link below.

    Hibersap

    A Java library to communicate with SAP

    Hibersap helps developers of Java applications to call business logic in SAP backends. It defines a set of Java annotations to map SAP function modules to Java classes as well as a small, clean API to execute these function modules and handle transaction and security aspects. Hibersap's programming model is quite similar to those of modern O/R mappers, significantly speeding up the development of SAP interfaces and making it much more fun to write the integration code. Under the hood, Hibersap either uses the SAP Java Connector (JCo) or a JCA compatible resource adapter to communicate with the SAP backend. While retaining the benefits of JCo and JCA like transactions, security, connection pooling, etc., developers can focus on writing business logic because the need for boilerplate code is largely reduced.

    MythCore

    Myth Framework Core Libraries (part of MythSDP)

    MythCore is a PHP framework that allows the developer to use a C# .NET like object oriented programming approach. It provides the essential classes that the MythSDP platform and the MythFramework builds upon. The goal is to create a library that enables the programmer to use a fully object oriented approach that has the "feel" of .NET and Java programming. Our main goal is ease of use and rapid application development. However, performance and small-footprint are some of the main design goals as well.
