Two articles about JavaServer Faces (JSF) and AJAX where recently published on java.sun.com...

Recently, two useful articles on JSF and AJAX have been released on java.sun.com to appeal to a developer who is experimenting with AJAX enabled JSF components.   They are as follows:


The articles depict advanced techniques in a way that should be understood by a developer that has limited experience developing JSF components.

More advanced write-ups on JSF, AJAX and the Java Persistence API can be found in the Java BluePrints Solutions Catalog.  There are also useful AJAX enabled JSF component libraries available for use in your own applications.

Hope this helps - Mark

The Java BluePrints Team has just corrected and unintentional omission in the Java BluePrints Solutions Catalog Java EE 5

The Java BluePrints Team has just corrected and unintentional omission in the Java BluePrints Solutions Catalog Java EE 5 version.  In the previous versions of the Java EE 5 Solutions Catalog, only the Java EE 5 components had their source code included.  The J2EE 1.4 components binary library was included, but the source was accidently omitted. 

We have just created a second distribution that includes the J2EE 1.4 component's source and a simple ant build system, so the components can be built and the resultant jar can be used in your application or the jar can replace the J2EE 1.4 library that the Java EE 5 Solutions Catalog uses.

The second distribution entitled "bpcatalog-14-ea-0.6-installer.jar" includes the following components' source:


Future versions of the Solutions Catalog will include these bits.

Sorry for any inconvenience - Thanks - Mark

The Java BluePrints Petstore 2.0 Reference Application that uses Web 2.0 technologies like AJAX, RSS and client-side/server-side mashups is now available for download...

The  Java BluePrints Petstore 2.0 Application is a reference application designed to illustrate how the Java EE 5 platform can be used with Web 2.0 technologies.  It shows real-world examples of AJAX, RSS and client-side/server-side mashups that can be used with Java EE 5 technologies like JavaServer Faces (JSF) and Java Persistence APIs.  The application comes with full source-code that utilizes the Google Maps service for location specific searches of pets, the PayPal service for purchases, an RSS feed as a data source, and much more.

Many of the AJAX enabled JSF components, like the Popup Balloon, FileUpload with Progress Bar, Auto-Complete, Rating, PayPal mashup, Google Map mashup, Yahoo GEO Code Mashup, and RSS Bar came from the Java BluePrints Solutions Catalog that can also be downloaded and used in your web applications.  The components and write-ups that the Solutions Catalog contains are described in more detail in a previous entry from my blog.

All that needs to be done to get started is to download and install Sun's Open Source Application Server, Glassfish and then download, configure, and deploy the Petstore 2.0 reference application.  This is a great opportunity to jump start you and your web application with Web 2.0 functionality with a minimal learning curve.

Below are some screen shots of the main pages in the application with brief descriptions of the pages functionality.

Hope this helps - Thanks - Mark


Main Catalog Page

Catalog Screen

This screen shot is of the main catalog page that contains a large amount of functionality and is the center of the Petstore 2.0 reference application.  Some of the main functionality it includes is as follows:


PayPal Page

PayPal Mashup

This is a screen shot of the PayPal Developer sandbox page that is populated with the catalog item data from the Petstore's database.  This page is presented when the "PayPal" button is clicked on from the Petstore's Catalog Page.


Apache's Lucene Search Engine Page

Search Page

This page is the front-end search page that utilizes the Apache's Lucene Search Engine on the server.  This page searches the indexes and displays a list of results that matches all the entered words in the search string. The AJAX Popup Balloon component that shows more detailed information is triggered when the user mouses-over the name for more than a second.  This page is also a lead- in to the Google Maps client-side mash-up page.  The user can select the items that they want shown on the map and by entering an optional center-point address with a search area (in miles), can further restrict the map to show only the items in the specific area around the center point.

More information about our experiences using the Apache's Lucene Search Engine can be found in a previous entry from my blog.


Google Map Search Page

Map Search Page

This page is the front-end map page that utilizes the database through the Java Persistence APIs to retrieve catalog items by category.  This page leads into the Google Maps client-side mashup page and displays the catalog items on the map for the selected category.  By entering an optional center-point address with a search area (in miles), the user can further restrict the category to show only the items in the specific area around the center point.


Google Map Mashup Page

Map Page

This screen shot is of the Google Maps client-side mashup page and shows the selected items, either from the Lucene Search page or the Map Search page.  Some of the main functionality it includes is as follows:

Seller Catalog Item Upload Page

Seller Page

This screen shot is of the second pane of the Seller Catalog Item Upload Page and shows the item's image being uploaded to the server while displaying the status of the upload to the user.  Some of the main functionality it includes is as follows:
