Castor

Castor is a data binding framework for Java with some features like Java to Java-to-XML binding, Java-to-SQL persistence, paths between Java objects, XML documents, relational tables, etc. Castor is one of the oldest data binding projects. Process flow Basic process flows include class generation, marshalling, unmarshalling, etc. Marshalling framework includes a set of ClassDescriptors and FieldDescription to describe objects. Class generation Class generation is similar to JAXB and Zeus. Castor supports XML Schema instead of DTDs (DTDs are not supported by Castor). Unmarshalling and marshalling Unmarshalling and marshalling are dealt with marshall and unmarshall methods respectively. During marshalling, conversion process from Java to XML is carried out, and, during unmarshalling, conversion process from XML to Java is carried out. Mapping files are the equivalent of a binding schema, which allows to transforms names from XML to Java and vice versa.
