How to generate sitemap for multi site environments? - Adobe CQ5/AEM

How to generate sitemap for multi site environments? - Adobe CQ5/AEM

This post will explain how to generate the sitemap for different sites(home pages) in multi site environment

Factory servlet to generate the sitemap.xml:

import java.io.IOException;
import java.util.*;

import javax.servlet.ServletException;
import javax.xml.stream.*;

import org.apache.commons.lang3.time.FastDateFormat;

public final class SiteMapGeneratorServlet extends SlingSafeMethodsServlet {

private static final Logger LOG = LoggerFactory.getLogger(SiteMapGeneratorServlet.class);
private static final FastDateFormat DATE_FORMAT = FastDateFormat.getInstance("yyyy-MM-dd");
private static final boolean INCLUDE_LAST_MODIFIED_DEFAULT_VALUE = false;

@Reference

@Activate
protected void activate(Map<String, Object> properties) {
this.incLastModified = PropertiesUtil.toBoolean(properties.get(INCLUDE_LAST_MODIFIED_PROPERTY),
INCLUDE_LAST_MODIFIED_DEFAULT_VALUE);
}

@Override
protected void doGet(SlingHttpServletRequest slingRequest, SlingHttpServletResponse slingResponse)
throws ServletException, IOException {

slingResponse.setContentType(slingRequest.getResponseContentType());
ResourceResolver resourceResolver = slingRequest.getResourceResolver();
PageManager pageManager = resourceResolver.adaptTo(PageManager.class);
Page pageObj = pageManager.getContainingPage(slingRequest.getResource());

XMLOutputFactory outputFactory = XMLOutputFactory.newFactory();
try {
XMLStreamWriter stream = outputFactory.createXMLStreamWriter(slingResponse.getWriter());

stream.writeStartDocument("1.0");
stream.writeStartElement("", "urlset", SITEMAP_NAMESPACE);
stream.writeNamespace("", SITEMAP_NAMESPACE);

// Current page
writeXML(pageObj, stream, slingRequest);

for (Iterator<Page> children = pageObj.listChildren(new PageFilter(), true); children.hasNext();) {
Page childPage = (Page) children.next();
// If condition added to make sure the pages hidden in search in page properties do not show up in sitemap
if (null != childPage) {
if (!childPage.getProperties().containsKey("hideInSearch")
|| (childPage.getProperties().containsKey("hideInSearch")
&& childPage.getProperties().get("hideInSearch").equals("false"))
|| (childPage.getProperties().containsKey("hideInSearch")
&& childPage.getProperties().get("hideInSearch").equals("")))
writeXML(childPage, stream, slingRequest);
}
}

stream.writeEndElement();
stream.writeEndDocument();

} catch (XMLStreamException e) {
throw new IOException(e);
}
}

private void writeXML(Page pageObj, XMLStreamWriter xmlStream, SlingHttpServletRequest slingRequest)
throws XMLStreamException {
xmlStream.writeStartElement(SITEMAP_NAMESPACE, "url");

String protocolPort = "http";
if (slingRequest.isSecure())
protocolPort = "https";

String locPath = this.externalizer.absoluteLink(slingRequest, protocolPort,
String.format("%s.html", pageObj.getPath()));

writeXMLElement(xmlStream, "loc", locPath);

if (this.incLastModified) {
Calendar calendarObj = pageObj.getLastModified();
if (null != calendarObj) {
writeXMLElement(xmlStream, "lastmod", DATE_FORMAT.format(calendarObj));
}
}
xmlStream.writeEndElement();
}

private void writeXMLElement(final XMLStreamWriter xmlStream, final String elementName, final String xmlText)
throws XMLStreamException {
xmlStream.writeStartElement(SITEMAP_NAMESPACE, elementName);
xmlStream.writeCharacters(xmlText);
xmlStream.writeEndElement();
}

}

Create new servlet configuration from the factory through OSGI console by providing the following details

Home Page Resouce Type - add the Home page resource types that should be considered for generating sitemap.xml

Include Last Modified Date - If selected the last modified date of the page will be included as part of the sitemap.xml

How to exclude the replication agent from manual replication actions - Adobe CQ5/AEM?

How to exclude the replication agent from manual replication actions - Adobe CQ5/AEM?

Exclude the replication agent from manual replication actions- Sometimes we may required to exclude the specific replication agents from manual action but only the actions through workflow or API.

Enable "Ignore Default" in Triggers tab of Agent configuration wizard.

How to display the dynamic popup in a page through GTM?

How to display the dynamic popup in a page through GTM?

This post will explain how to display the dynamic popup in a page through GTM.

The assumption is the required JQuery scripts are included as part of the page.

Define the cookie type variable: - this will help us to display the popup for every new browser session(this step is not required if the popup should displayed every time visiting the page)

  • Click on Variable in left hand side menu.
  • Go to user defined variables and select new.
  • Select variable configuration as 1st party cookie 
  • Give cookie name as popUpDisplayed and check url decode cookie option.
  • Save the changes and give the name as popUpDisplayed.

How to monitor the Replication Queues through Java - Adobe CQ5/AEM

Monitoring the Replication Queues through Java - Adobe CQ5/AEM

This post will explain the approach to monitor the Replication Queues through java

Enable the Remote JMX in the server:

Add the following configurations as part of CQ_JVM_OPTS in AEM startup file (start.sh or start.bat)

-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=50055

e.g.

CQ_JVM_OPTS='-server -Xmx6144m -XX:MaxPermSize=512M -Djava.awt.headless=true -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=50055'

Restart the server.

Configuration.txt

Email_From=xxxxxxx

}

Configure the data in Configuration.txt file accordingly.
Email will be triggered whenever the configured Queue is disabled, blocked, paused or the pending request is more than the configured threshold.

Executable jar file can be generated for the java class and scheduled for continuous monitoring.
