Professional services


As already explained, Castor is an open-source product. This means that the source code is available at no charge and may be obtained from github using git. Due to the open source nature of the project, there is no guaranteed level of support (of commercial quality) offered by the project and its community.

Still, there are a growing number of third party individuals/companies providing such support in the form of professional services. This page provides you with a directory of individuals/companies offering commercial services related to individual or all areas of Castor.

We hope that the information provided is of value to you, our users, and the individuals/companies displayed below will be more than happy to discuss any suggestions/recommendations related to this offerings.

CODA: Financial Intelligence (

Contact: Andrew Fawcett (

As a developer of international financial management and procurement systems, CODA started a project to XML-enable our Financials application server,“ noted Andrew Fawcett of CODA. ”We made two major technology decisions. The first was to use the W3C XML Schema to describe our XML messages. The second was to facilitate the use of an XML Data Binding framework. This allows our developers to process XML messages in a more productive and intuitive way within their programs, without requiring extensive training and experience with XML or its traditional APIs such as SAX or DOM. In performing an analysis of XML Data Binding frameworks, we found that Castor was the only implementation at the time that met our needs in terms of its support for W3C XML Schema and its ability to integrate with our Web infrastructure.

In addition, we use Castor internally within our Web client-enabling framework (based on the Java Servlet API). Java source code produced by the Castor source code generator is used to dynamically bind data to our Web forms. The resulting data can then be marshaled directly between our Web applications and application server."
