How to Customize/Configure the 404 error handler for multi sites in AEM/Adobe CQ5?

This post will explain how to configure the 404 error handler in multi site scenario for Adobe Experience Manager(AEM) - This will configure different 404 pages for different sites..

If the error handler is configured for first time then copy /libs/sling/servlet/errorhandler to /apps/sling/servlet (create the folder structure before copying )

Modify /apps/sling/servlet/errorhandler/404.jsp file to modify the 404 error handling rules.

<%  
//setting response code as 404
response.setStatus(HttpServletResponse.SC_NOT_FOUND);
try {
    String uri = request.getRequestURI();
         
    if(uri.matches("(/content/Sample/en/)(.*)"))
    {
        pageContext.include("/content/Sample/en/404.html");
    } else if(uri.matches("(/content/Sample/es/)(.*)"))
    {
        pageContext.include("/content/Sample/es/404.html");
    } else if(uri.matches("(/en/)(.*)"))
    {
        pageContext.include("/content/Sample/en/404.html");
    }
    else if(uri.matches("(/es/)(.*)"))
    {
        pageContext.include("/content/Sample/es/404.html");
    } else
    {
        pageContext.include("/content/Sample/en/404.html");
    }

} catch (Exception e) {

%>
        Page Not Found
<%
}

%>

The conditions can be added to handle different sites, if the sites are running on different virtual host names then get the server name from the request
(request.getServerName()) and add the condition based on the server name.

This will redirect the user to site specific 404 pages.

How to get the child Pages of a root Page through Java API - AEM/Adobe CQ5

This post will explain how to get the child Pages of a root Page through Java API in Adobe Experience Manager(AEM)

public static PageFilter getPageFilter() {
PageFilter pf = new PageFilter();
return pf;
}

public static Iterator<Page> getPageIterator(Page page){
Iterator<Page> children = page. listChildren(getPageFilter());
return children;
}

Filter can be changed to restrict child pages e.g Get the child pages created only with the template "/apps/sample/templates/samplePage"

public static PageFilter getPageFilter() {
PageFilter pf = new PageFilter() {
public boolean includes(Page p) {
ValueMap props = p.getProperties();
String templatePath = props.get("cq:template",String.class);
if("/apps/sample/templates/samplePage".equals(templatePath))
{
return true;
} else
{
return false;
}
}
};
return pf;
}
