1> As a first step you need to implement Converter interface in a class to achieve the required column conversion. Check org.apache.tuscany.das.rdb.test.mappings.StringObfuscationConverter from the svn repository for example of converter. Make your converter class available in (Tomcat root)webapps/companyweb-webapp/WEB-INF/classes. 2> DAS functions based on external Configuration, e.g. CompanyConfig.xml file in companyweb sample. The purpose of this Config file to supply information for DataSource connection, Commands (SQL) (that DAS can execute against Database) and Database schema like - Table/Columns, Relationship and so forth. Please check Architecture Guide for complete details about Config.xsd () at http://incubator.apache.org/tuscany/rdb-das-architecture-guide.html |
