How exactly It happens !!!!!!!

[Prashant Baviskar-2]

Hi,

I am new to struts.

Can any one explains when we submit the form,

How the struts-config.xml is read,

How form bean is populated,

>>>>>How validator plug-in is read from deployment descriptor.

>>>>>How validation is performed

& how execute method gets called.

 

Question indicated with arrow are more important.

As I want to explicitly call validator framework of struts (Without using
struts framework & web/app server).

I want to know the classes in struts framework which are responsible for
this

 

--Thanks & Regards

Prashant Baviskar

Hi Prashant

I recomend you to read the starting guide, it comes with the struts bundle
and explains everything you've asked, you can read it online here:
http://struts.apache.org/1.3.9/userGuide/index.html

Prashant,

If you want to know how exactly Struts handles the request, you can
use MaintainJ Eclipse plugin to generate the runtime UML sequence
diagram. It clearly shows the object interaction at runtime, which
would give you a quick overview.

Check the http://maintainj.com/userGuide.jsp?param=jar#runningApps for
a sample Struts application using Struts 1.1 jar files.

For a quick look, check these sample sequence and class diagram
snapshots that deal with the form validation.

Struts validation sequence diagram -
http://maintainj.com/samples/StrutsValidatorSequence.jpg

Struts validation class diagram -
http://maintainj.com/samples/StrutsValidatorClass.jpg

MaintainJ can be used to generate simple and useful runtime sequence
and class diagrams for any Java application with either source code or
jar files. It takes a very different approach than existing reverse
engineering tools and answers exactly the kind of questions you just
asked - 'What exactly happens when I click this button?'.

Regards,
Choudary Kothapalli.

Struts validation uses apache commons validation. If all you want is
the validation techniques you want the apache commons validation. The
code called by the struts validator is the code of apache commons
validator. If you don't want the struts framework or any kind of
web/app server, then why would you care about how struts does
anything. If you need to validate a value apache commons wil help you.

http://commons.apache.org/validator/

I get the feeling you want to define an xml file with validation rules
and plug this into an app. Apache commons validator is what you want
to use. It has everything you need. What is it about struts that you
want that isn't covered by apache commons validator?
