Overview / CRX 2.3 Documentation / 

First Steps in CRX

This page provides information about the latest CRX release in a nutshell. It is mostly intended for web developers and IT professionals, who would like to understand the basic product capabilities quickly.

You will only need minutes to get a good grasp of what CRX can do for you.

Step One: Watch Web Development with CRX Screencast

Watch the 15-minute Web Development with CRX Screencast on www.day.com.

The screencast walks you through the main product modules, while presenting our "CRX Bookstore" example application, which is an open source application presenting the main aspects of web application development on CRX platform.

The screencast has the following parts:

  • Developing with CRXDE Lite
  • Using Subversion (SVN) Integration
  • Understanding CQ5 Platform: RESTful, resource-oriented architecture of CRX's application platform based on Apache Sling
  • Understanding runtime application framework, running OSGi Service Framework based on Apache Felix
  • Understanding how CRX Bookstore application is built and how it can be extended
  • How to store content in the repository
  • Accessing data from desktop (WebDAV)
  • Understanding deployment: working with Content Packages

Step Two: Check out CRX Bookstore Example

Now check out the CRX Bookstore sample project yourself - literally!

Follow the screencast to export the project code and initial content from the CRX Bookstore project's svn server to your CRX.

In CRXDE Lite - the Develop button on the welcome screen - log in as administrator (admin/admin), go to Team > Checkout, and check out the following two projects into CRX:

  • Application will get installed into /apps/bookstore
    • URL: crxzon.googlecode.com/svn/trunk/apps/bookstore/
    • Path: /apps/bookstore
    • Click OK and wait for the console to show the summary of the operation
  • Initial / sample data will get installed into /products
    • URL: crxzon.googlecode.com/svn/trunk/products/
    • Path: /products
    • Click OK and wait for the console to show the summary of the operation

You can also use Svn Export command (Team > Export) to do the same if you do not need a SVN working copy in your repository.

Now, the only thing to have the running CRX Bookstore is to compile its executable library:

  • Go to /apps/bookstore/src/impl/com.day.crx.sample.bookshop.bnd - this is the OSGi bundle definition for our library
  • Use Tools > Build Bundle to build and deploy the code.

You are done with the development. Now, go to /products.html to see the running bookstore application.

  • localhost:7402/products.html

Your sample application is up and running. Explore its functionality - it is just a sample, but it offers all the major functionalities of an online store.

Next, go back to CRXDE Lite and discover, how the application is build.

Finally, you might try to change or extend the application slightly. There's no better way to learn than to try things out yourself. And if you an interesting enhancement, new feature, or idea, feel free to contact CRX Bookstore project team to discuss how you could contribute this to the project. Or, if you are a project committer - just Checkin your changes from CRXDE Lite.

Next Steps: Discover the Product

At this point, you should have a pretty good practical understanding of major technologies and how they work together in the product.

Next steps that we recommend are the following.

  • Use the product more, and discover its other features. Some prefer to do it by just clicking and trying things out. Try the "Learn More" link on the Welcome Screen, it has a few more simple example applications to check out to see how things work.
  • Or you could check the product documentation, we have some good introductory information there.
  • There is also a longer, more detailed Getting Started for Developers guide, with more information about technologies, and a detailed step-by-step example of how to create a simple blog application
  • Check out our Developer Portal, with blog, discussion groups, and a lot of interesting and fresh information

We hope you liked the product! Let us know your comment below on this page.

      Javier,
      Not sure what issues you were getting but here is what I am facing.
      1) After checking out the code and data I dont see it in a folder structure as shown in the screen shots. For example I dont have a bookstore folder under apps but folder structure like /apps/src/impl...
      2) When I try to build I get the following 3 errors:
      The method listChildren() is undefined for the type Resource. /apps/src/impl/src/main/java/com/day/crx/sample/bookstore/Account.java (line 46)
      The method listChildren() is undefined for the type Resource. /apps/src/impl/src/main/java/com/day/crx/sample/bookstore/Order.java (line 91)
      le cannot be resolved. /apps/src/impl/src/main/java/com/day/crx/sample/impl/RankingServiceImpl.java (line 140)

      Thanks

            Can you confirm which version(s) you are using?

            Also are you using the bookstore example package?

            According to the naming/filing in package share, the bookstore example was designed for CRX 2.1.0.

          Checkout of products from crxde lite was timing out. I used eclipse crxde for checking out products.

            Console Output upon trying to do import:

            IMPORT /apps/bookstore (2012-01-14 18:11:08)

            svn: MKACTIVITY of '/svn/!svn/act/c31d7dde-3401-0010-8fd9-9ff16f3d1a28': 405 Method Not Allowed (crxzon.googlecode.com) svn: MKACTIVITY request failed on '/svn/!svn/act/c31d7dde-3401-0010-8fd9-9ff16f3d1a28'

                Unfortunately Chrome is not a supported platform for CQ 5.4. It will be supported for 5.5. See dev.day.com/docs/en/cq/current/deploying/technical_requirements.html for 5.4 supported platforms.
