Configuring the Adobe CQ Dispatcher

Over the past couple of weeks, we’ve created content that addresses several top questions related to the Adobe CQ Dispatcher. This is in response to questions we’ve heard from you, our community. I encourage you to give a read and also check out the more in-depth documentation I link to further below.

Creating MBeans for your CQ5 application

-- Jörg Hoh

JMX is the de-facto standard for monitoring java processes and applications. A lot of monitoring systems have the ability to consume these data.

By default CQ 5.5 has a number of MBeans, which offer runtime information about internal state. Most interesting ones are the MBeans about the repository state and the replication MBeans. But it isn’t hard to create your own MBeans, so you provide information about the internal state of your application to the monitoring system; or you can monitor resources which are critical to your application and use case.

In Cq5 we are working in a OSGI environment, so we will use one of my favorite patterns, the OSGI whiteboard pattern. We will use the JMX-Whiteboard bundle of the Apache Aries project to register services to JMX. Also that implementation is very short and understandable and shows the power of the whiteboard pattern. (I already had a short blog entry on this last year.)

In this example I want to demonstrate it on an already existing counter, the total number of requests handled by sling.It requires CQ 5.5, where the JMX whiteboard bundle is already deployed by default; but if you install the JMX Whiteboard bundle yourself, you can also use older versions of CQ5.

Author server says Loading; for a long, long, long time

- Sensei Martin

When the Author server restarts, it can look, to the users, like it is hanging because as soon as they click on a node in the left hand nav tree they see "Loading" in the central pane. It just sits there saying "Loading" for a long, long, long time.

This can be caused by having lots of old Workflow instances hanging around (check /etc/workflow/instances). In which case, you should ensure that you install the Workflow purge tool from Adobe.

The purge tool by default will clear out any Workflow instances which are less than 14 days old (well the version I have says > 1 day but the code was actually > 14 days). It can be configured to only purge COMPELTED workflow, or ALL of them. However, beware that the default configuration (in my version 1.6.1 anyway) will only purge the following workflow models :-

  • "/etc/workflow/models/dam/dam_asset_syncer_and"
  • "/etc/workflow/models/dam/update_asset"
  • "/etc/workflow/models/dam/delete_asset"
  • "/etc/workflow/models/dam/delete_dam_asset"

Creating custom CQ email services

- Scott Macdonald

You can create a custom CQ email service that lets CQ users send email messages from a CQ web page. To create a CQ email service, you develop an OSGi bundle that uses the Java Mail API. You can also develop a JSP that uses JQuery that calls the OSGi service and passes data that is sent as an email message.

 Caption – A CQ email client

To follow along with this development article, you need to download the Java Mail API at the following URL:

http://www.oracle.com/technetwork/java/javamail/index.html

The Java Mail API is used within the OSGi bundle that sends email messages when the client initiates a request. The CQ email service comprises of a client (shown in the previous illustration) developed by using JQuery and an OSGi bundle.

CQ 5.5: Changes to the startup

- Jörg Hoh

See here for the major changes brought with this release.

Amongst the hundreds of new features I would like to point out a single one, which is probably the most intersting features for admins and operation people.

With CQ 5.5 the quickstart does no longer start a servlet engine with 2 webapplications deployed in it (crx.war for the CRX and launchpad.war for the OSGI container including Sling and CQ5 itself). But as now CRX has been adapted work inside an OSGI container it is possible to drop the artifical differentiation between CRX and the other parts of the system, but handle them alike inside Apache Felix. The same applies to the CQSE servlet engine; it’s now an service embedded into OSGI (so the server.log file is gone). So the quickstart starts the Felix OSGI container which then takes care of starting the repository services, the servlet engine and all other services introduced by Sling and CQ5. This streamlined the startup process a lot. And — finally — there is only 1 place where you need to change the admin password.

Integrating custom CQ widgets with third-party libraries

- Scott Macdonald, Senior Content and Community Lead @ Adobe

Have you ever wondered how to create a custom CQ widget that performs tasks not available with out of the box CQ components. In this situation, you can create a CQ widget that uses third-party libraries that lets your CQ application perform custom tasks. For example, assume that you want to create a CQ application that lets you view a specific street by using Google Map APIs.

Perhaps, you want your CQ component to accept latitude and longitude values and then show the results, as shown in the following illustration.

If you are interested in learning how to create CQ components that use third-party libraries, then check out the following article:  http://helpx.adobe.com/adobe-cq/using/integrating-custom-cq-widgets-third-party.html.
