cvs commit: jakarta-struts/src/share/org/apache/struts/upload package.html

rleland     2002/11/05 20:48:29

  Modified:    src/share/org/apache/struts/action ActionMapping.java
                        DynaActionForm.java
               src/share/org/apache/struts/config ActionConfig.java
                        ApplicationConfig.java
  Added:       src/share/org/apache/struts/config ModuleConfig.java
               src/share/org/apache/struts/config/impl
                        ModuleConfigImpl.java
               src/share/org/apache/struts/upload package.html
  Log:
  Bug 14054
  Initial limited checkin of ApplicationConfig->ModuleConfigImpl rename
  and ModuleConfig Interface.
  All classes except ActionServlet will use the ModuleConfig Interface.
  Initially ActionServlet will directly use the ModuleConfigImpl class
  when creating. Later a ModuleConfigFactory
  will be introduced.
