Architecture Chaos of Web 2.0 Application

Struts, Spring, Seam, JSF, Hibernate, iBatis, Ajax and EJB, there are so many java technology, my question is which one should go for to mix and match out a wonderful J2EE Web 2.0 architecture for new project.


Model layer

Spring+Hibernate
Spring+iBatis (With skillful DBA or developers with advnaced sql skill)
EJB 3.0, forget about the EJB 2.1 (with developers expert in JDK 1.5 and annotation)

View & Controller layer

Struts1 + Ajax (zk/echo/gwt) + Tile (templating)
Spring MVC + Ajax (zk /echo/gwt) + Tile (templating)
JSF+Icefaces/Zk(AJAX)+Facelet / Tile(templating)
RichFaces / AJAX4JSF

Integration Layer

Web services
BPEL process (a collection of inter-related web services)
Enterprise Service Bus
JMS & MOM

Other than suggestion above, JBoss seam and Oracle ADF and Webcenter come with full technology stack for web 2.0 architecture.

As for which technology and plaftform should be used in the development, not only it depends on the value and benefits technology bring to the project, but available tools and people to support and accelerate the development play a part as well.

Only with good tools (development & testing) and big pool of talent people/developer, project can be delivered on time.

So, which tools should be chosen for the project development? Again, there are many open tools available in each phase of SDLC.

Someone can use a combination of tools below:

Eclipse with Checkstyle, PMD, Mylar, Subversion (Subclipse), JUnit plug-ins
Subversion version control
maven2
Jira issue tracking
Confluence wiki
Cobertura test coverage
QuickBuild Continuous Integration system
Enterprise Architect for requirements and design in UML, and document generation

But it may not fit your project and you will need to figure out your own tool set with some R&D work on it.

Here, i would like to suggest a book (not-yet-published, but coming-soon) called "Java power tools". It maintain a comprehensive open tools and I believe with this book, people can shorten the R&D work for development tools findings.

So, what is your voice for this confusion and chaos?
