Icing

WHAT IS IT?

Icing is a collection of components that, taken together, form a simple web-development framework. Icing is a set of Scheme libraries, built atop SISCweb and making use of SXML and SXpath, that support servlet development within a J2EE environment. It includes:

a simple bean-like layer atop raw SQL, with an S-expression based SQL syntax and objects representing table rows
a small library (not quite the same as SISCweb's approach) to allow pattern-matching on the URLs of incoming requests, and to allow attaching handlers to matched URLs
libraries for using JavaMail to construct and send arbitrary MIME multipart message parts and for using BouncyCastle's PGP implementation with JavaMail to build PGP MIME email bodies and attachments
a XSLT-template-based Model-View-Controller-plus-Workflow framework for structuring applications. HTML templates (with special attributes and with optional embedded XSLT instructions) form the View; Scheme code forms the Controller; the DB layer referred to above forms the core of the Model; and SISCweb's support for continuation-based web programming forms the Workflow

The software is still very new; we're currently in the process of documenting it, packaging it conveniently for use in other applications, and deciding how to split it into separate individually-reusable components.

HOW DOES IT WORK?

WHERE DO I GET IT?

Icing is freely available under the liberal MIT open source license.

We've uploaded a snapshot of Icing, including its dependent xml.pipeline library. You'll need to have a Tomcat v4.1.30 installation available. Newer versions of Tomcat probably work, but are not guaranteed to.

Download icing-20060721.tar.gz, and unpack it somewhere convenient. Installation instructions are in the README file in the icing/icing-20060721 directory.

Do note that this is a snapshot release, and as such is full of rough edges!
