Hi Sudipto,
Sorry - I dropped this one - I meant to reply to you earlier.
But you have already done what I had to do, albeit slightly differently. I
wrote my own logon servlet and controller servlet by extending
LogonServlet and ControllerServlet, respectively, and specifying them
in the web.xml file (, editting "<servlet-name>Logon</servlet-name>"
and "<servlet-name>Controller</servlet-name>", respectively).
I also had to make minor mods to, I think, the getters:
@Override
protected WebController getWebController(PathBuilder pathBuilder)
{
return new SaipWebController(pathBuilder);
}
// //////////////////////////////////////////////////////////////////
// doGet, doPost
// //////////////////////////////////////////////////////////////////
@Override
protected HtmlComponentFactory getHtmlComponentFactory() {
return new SaipHtmlComponentFactory(getPathBuilder());
}
I have not committed those changes, it seems.
In the "SaipHtmlComponentFactory", I could provide any of my own
components, as required:
@Override
public LogonFormPage createLogonPage(final String user, final String
password, boolean registerLink, String error) {
return new SaipLogonFormPage(pathBuilder, styleSheet, header, footer,
user, password, registerLink, error);
}
@Override
public Component createInlineBlock(String style, String text, String
description) {
return new SaipSpan(style, text, description, false);
}
public Component createSaipBlock(String style, String text, String
description) {
return new SaipSpan(style, text, description, true);
}
public Component createFile(String style, String description, String
fileName) {
return new SaipFileHtml(style, description, fileName);
}
Where Saip* are my custom classes.
Regards,
Kevin
