Turns out to not be such a big deal. I added the following:
===================
to my Properties
===================
ticoon.replacement.classes = (PageWrapper, ticoon.web.LoginPanel)
===================
to my Application class
===================
public void initializeTicoon(NSNotification event)
{
// startup
NSArray classesToReplace = PropertyTool.ArrayValue
( "ticoon.replacement.classes" );
if ( ArrayTool.IsEmptyArray( classesToReplace ) == false)
{
/** install patch components that must be 100% API compatible with
each other */
String baseclasspath = "ticoon.clients." +
sponsorShortName() + "." +
applicationName();
for ( int i = 0; i < classesToReplace.count(); i++ )
{
String item = (String)classesToReplace.objectAtIndex(i);
String itemName = item;
/* class to replace may be 'ticoon.report.Something' we want
to make that into 'ticoon.clients.sponsor.AdvisorSomething'
not 'ticoon.clients.sponsor.Advisorticoon.report.Something' */
int lastdot = item.lastIndexOf(".");
if ( lastdot > 0 )
itemName = item.substring(lastdot+1);
String fullpath = baseclasspath + itemName;
try
{
// example ticoon.clients.bank.AdministratorMain
Class replacement = Class.forName( fullpath );
com.webobjects.foundation._NSUtilities.setClassForName(
replacement, item);
}
catch ( ClassNotFoundException e )
{
/* not found, no replacement, use the default */
Log.Error( "Failed to replace " + item + " with " + fullpath );
}
}
}
}
/** override parent implementation to redirect component definitions
to patched class names. Superclass will use the full class name, and
strip off the package name when resolving the component name */
public WOComponentDefinition _componentDefinition(String s, NSArray
nsarray)
{
if ( StringTool.IsBlankContent(s) == false )
{
Class pageClass =
com.webobjects.foundation._NSUtilities.classWithName( s );
if ( pageClass != null )
{
/** this ensures that if we patch PageWrapper with
ticoon.clients.sponsor.AdvisorPageWrapper that the
AdvisorPageWrapper.wo is parsed instead of the original */
s = pageClass.getName();
}
}
return super._componentDefinition(s, nsarray);
}
