When an ATG server instance is started, the framework data that is stored in XML files is unmarshalled for conversion. The unmarshalling process first combines the XML framework object definitions using the xml-combine XML attribute. For detailed information on xml-combine and data binding, refer to the ATG Platform Programming Guide.
Once the XML files are combined, the data is then unmarshalled. The unmarshalled data is available as a framework-template, which is the root element for all framework objects and is used to access all framework and other related elements.
When the data is unmarshalled, the ObjectFactory class creates various instances of framework objects. The following components are used to catalog framework object servlet bean instances in a map, and provide a finder method to obtain framework definition objects:
The
FrameworkHomeDefinitionXMLHomeobjects such asatg.svc.framework.or
xml.CellDefinitionXMLHomeContentDefintionXMLHomecontain methods that find framework objects based on application requirements. These are known as finder methods. In the following example, framework object servlet bean instances are cataloged into acacheMapproperty. The key value pairs are created and initialized based upon the application’s requirements. The finder methods then access the data from thecacheMapproperty:public class FrameworkDefinitionXMLHome extends
_FrameworkDefinitionHome_BeanImpl
implements FrameworkObjectInitializer {
protected Map mCacheMap = new HashMap();ServiceFrameworkXMLHomesholds references to theFrameworkHomeDefinitionXMLHomeobjects home definition. TheFrameworkDefinitionHome.propertiesfile contains theFrameworkDefintionXMLHomeinstance. For example:$class=atg.svc.framework.repository.beans.ServiceFrameworkXMLHomes
