private com.sun.enterprise.web.PEWebContainer
webContainer
The WebContainer instance.
Constructors Summary
public TomcatApplicationLoader(String appID, ClassLoader parentClassLoader, com.sun.enterprise.instance.AppsManager appsManager)
TomcatApplicationLoader loads one application.

param
appID the name of the application
param

Methods Summary
protected booleandoLoad(boolean jsr77)
Called from ApplicationManager. Called to load an application. This loads the web modules of this application on top of its super loader creating the EJB and MDB container.

return
true if all modules were loaded successfully
