A quick demonstration

The architecture

How it’s wired together

The WQS API

How requests are handled

Creating and using a new page template

Primary goal:

• To equip you with knowledge of how the web tier of WQS works so

that you can start building your own websites based on it

What we’ll cover

Transfer Service

WQS API WQS API

web.xml

web-application-config.xml

wcmqs-webapp-context.xml

surf-config.xml

Creates Spring

dispatcher servlet

Loads up surf-config and

wcmqs-webapp-context

Bootstraps Surf itself and

defines new default request

handler and interceptors

Other request handlers, view

resolvers, Freemarker

directives, and interceptors

• API wired with “wcmqs-api-context.xml”

• Auto-bootstrapped when dropped into a Surf application

• Properties that can be adjusted (with their defaults):

• wcmqs.api.alfresco=http://localhost:8080/alfresco

• wcmqs.api.user=admin

• wcmqs.api.password=admin

• wcmqs.api.alfresco.cmis=%{wcmqs.api.alfresco}/service/cmis

• wcmqs.api.alfresco.webscript=%{wcmqs.api.alfresco}/service/api/

• Override in a file named “wqsapi-custom.properties” in the

“alfresco/extension” folder on the classpath

8

• Bean “webSiteService” is

a good starting point:

9

10

• Executes before the default controller is reached

• Uses the requested URL to find the website, section, and

asset that are being addressed

www.example.com/news/global/financial_outlook_good

• Stores the API objects on the request context with the

names “website”, “section”, and “asset”.

website

section

asset

11

• Wired in to respond

whenever an asset has

been resolved

• Discovers the page name

to be used to render the

asset

• Each section may define

template mappings from

asset type to view name

• Searches up the type

hierarchy first, then the

section hierarchy

12

• org.alfresco.wcm.client.controller.StreamedAssetController

• Provides support for simple-to-generate, permanent URLs

for assets:http://localhost:8081/wcmqs/asset/de2f9b66-6bbd-4347-8f24-4ed06299ad8a

• Slightly faster to generate

• Remains the same when the asset is renamed or moved

• Supports renditions:…/asset/de2f9b66-6bbd-4347-8f24-4ed06299ad8a?rendition=mediumNewsThumbnail

• Still looks for the appropriate template

• Is mapped to the path “/asset/**” (in wcmqs-webapp-

context.xml)

13

• org.alfresco.wcm.client.controller.SearchFormController

• An example of a Spring

Annotation Handler

Search RSS

• org.alfresco.wcm.client.controller.RssController

• Another annotated handler

• Mapped to “**/rss.xml”
