JGrapes is an event driven component framework written in Java. It includes support for asynchronous I/O and provides some complex components such as an HTTP server and a portal. It was inspired by the “circuits framework” written for Python.
JGrapes makes full use of the Java 8 SE environment. The core framework has no dependencies on additional libraries. The component libraries extending the core have as few dependencies as possible.
The documentation of the framework and its components can be found in the JavaDoc. Make sure to check the package descriptions. They tend to be overlooked because they come after the sometimes rather lengthy list of packages or classes (though the standard layout does put a link to the description at the top of the page). To get started, read the framework’s architectural description on the overview page. This provides an introduction to the concepts, the main classes and links to the details.
The JavaDoc for the portal components is available here.
All jars have the required information in
to use them as (library) bundles in an OSGi environment, without
introducing a dependency on this environment. Built on top
of these libraries, there are some
components that fully integrate with OSGi (often just adapters for
the basic components). Because they are built in an independant
workspace, they have their own
