Seam / GWT Blogging Demo, version 0.2

This demonstration application is the Seam blogging demo, with a GWT browsing/editing interface integrated through JSF.

Key technologies used in this demo:

Seam 1.2.0-PATCH1 running with JSF 1.2
GWT 1.4 preview release source, including refactored RPC
A revised version of the G4JSF integration package, allowing direct invocation of service interfaces from a GWT module encapsulated in a JSF component
A bridge phase listener that couples the GWT and Seam phase listeners, allowing seamless invocation of service interfaces on Seam components
A simple code generator that creates JDK 1.4-compliant beans from JDK 5 source (to work around GWT's incompatibility with Java 5)

To view the application, unzip this archive, locate build/jboss-seam-blog.war, and drop it into a Tomcat webapp instance (tested on Tomcat 5.5.12 / JDK 1.5.0_11). Then visit http://localhost:8080/jboss-seam-blog, scroll to the bottom of the page, and click "[Browse with GWT]" The resulting page is a JSF XHTML template containing a GWT module, invoking service methods on a Seam "GwtBlogService" component to get data from and post data to the server.

See the included readme.txt for more information, including known bugs. Also see this explanatory article: article_0.2.html

Here is the demo (all source and compiled build included, please pardon the 41MB download): seam-blog-gwt-0.2a.zip

There is a problem running this under JDK 6; this problem is actually in the original Seam example. A bug has been filed in Seam JIRA: JBSEAM-1276.

I am planning to attend the Seam BOF at JavaOne (Tuesday May 8, 9 pm) to discuss this work. I will also be at Google's Mountain View developer day. All comments welcome, there, elsewhere, or by email :-)

Cheers!
