Sapon is a minimalist fork of selected Apache webservices projects, most notably Axis2 and Synapse. Where Axis2 offers a full-featured webservices framework, and Synapse aims to provide a complete Enterprise Service Bus, Sapon is primarily intended for simple filtering and redistribution of SOAP messages.
Some differences between Sapon and the upstream projects include:
-
Sapon specifies a minimum of Java 6. Sapon has the explicit goal (not yet completed) of transitioning to Java 6 idioms where they improve readability, type safety, performance, or resource management.
-
Sapon projects use Maven's default layout consistently. Poms are generally kept small and easy to understand, and intentionally do not take advantage of many of Maven's features.
-
Sapon has the explicit goal (not yet completed) of no compilation warnings.
-
Sapon's port of axis2-kernel replaces the MessageContext class with an equivalent interface, and is able to save some per-message memory by moving the bookkeeping needed for serialization to a lazily-initialized helper object. This is part of a larger goal to isolate a core set of interfaces that can peeled out into a stable api, so that projects based on that api can minimize the versioning deadlock that's a pain point of the current upstream projects.
-
Sapon drops functionality that is not needed for its limited aims, when doing so allows dependencies to be removed. Sapon has the explicit goal of shipping smaller deployables and reducing the effort required to understand and manage the project's dependencies.
-
Sapon uses Git for SCM. Fork away!
