net.sf.appinfo
Class ChainedApplicationInfo

java.lang.Object
  net.sf.appinfo.AbstractInitAwareApplicationInfo
      net.sf.appinfo.ChainedApplicationInfo

All Implemented Interfaces:

ApplicationInfo, InitAwareApplicationInfo

public class ChainedApplicationInfo
extends AbstractInitAwareApplicationInfo

ApplicationInfo implementation which can use the first initialized ApplicationInfo in a chain. Class intended to be directly used in application. It collects one or more ApplicationInfo objects in a chain and returns data from the first initialized (or able to initialize). The first in a chain could be a ApplicationInfo object which reads data from manifest file in JAR/WAR. Later instance using default application info given is static artifical manifest file placed in resources for use in development versions run from IDE. To be at the end of a chain FallbackApplicationInfo class was designed. Its initialization cannot fail nad therefor there is no risk to prevent IoC context from start. There is a default appInfo's Spring bean configuration in resources (appInfoDefaultContext.xml). It can be add to application's Spring conext configuration. More information is placed inside xml.
