Claudio Sacerdoti Coen has announced the release of version 1.2.0 of UWOBO, an open-source (GPL'ed) Java servlet for performing XSLT transformations (using Xalan) over the Web.

The UWOBO site provides a browser-based "control panel" [source code] you can use to control any local or remote UWOBO servlet, including instances of the servlet running on the project webserver at the University of Bologna. So you can use it to try out the servlet (without needing to download and install it locally).

UWOBO appears to be an extension of the HELM (Hypertextual Electronic Library of Mathematics) project, which has as its stated purpose is the development of

a suitable technology for the creation and maintenance of a virtual, distributed, hypertextual library of structured mathematical knowledge, eventually passing through the eXtensible Markup Language. The final aim is to allow mathematical documents to be served, received and processed on the Web, just as HTML has enabled this function for the text

The HELM library is rendered "on the fly" using the UWOBO servlet
