Experiences on integrating cforms and other frameworks like hibernate

[Rice Yeh <ri...@gmail.com>]

Hi,
  I am starting to use cform to implement web application and I have applied
MVC design pattern to the domain problems based on cocoon and cforms. I
separate sitemaps into 2 types. The first type is the controller which
invokes functions in javascript. The second type is the view that is invoked
by functions in javascript to show gui to users. Then I come to a problem
that although cocoon 2.2 has spring  framework in place but I cannot use it
to set  transaction attributes declaratively supported by spring framework
because I cannot use functions in javascript as join point. Actually, I like
to write flow-like business logics in javascript functions. It is so
straight with the help of flowscript. I treat each function in javascript
like a flow in a use case. However, many techniques used to work in java
language has to be reconsidered like to the above example. For the above
example, I am considering to use aspectj or spring aop to advice the
map:call (of coure, its java implememtation) to begin a transaction and the
sendPage() to commit the transaction based on a parameter passed within
map:call which tells the code in the advice whether the javascript function
needs a transaction.

The most examples I can get in cform are not needed to access db. So could
you guys share your experiences on integrating cforms and other frameworks
like hibernate and springframework?

Regards,
Rice

You should write services with help of spring and make them 
transactional. Your controller does not need make use of transactions.
