Hello Avijit,
It looks like you are getting confused from the concept of Events and
Services in java. It is very well explained in the OFBiz tutorial:
https://cwiki.apache.org/confluence/display/OFBIZ/OFBiz+Tutorial+-+A+Beginners+Development+Guide+for+18.12
Now talking about your code snippet:
You are calling an event from a controller so you need to get all the
parameters from the method request.getParameter("html_form_elements_name").
And once you have read all the values in events then from here you should
pass these values to the service where you can take care of business logic
and CRUD operations. Basically events are used to do the validations and
extra manipulations with the form parameters.
If you don't want to go with the Events route then you should change your
controller.xml entry as shown below:
<request-map uri="createStudent">
<security https="true" auth="true"/>
<event type="service" invoke="createStudent"/>
<response name="success" type="view" value="newStudent"/>
<response name="error" type="view" value="errorPage"/>
</request-map>
Here you will notice that I have used the event type as "service" where you
don't need to specify the path of the service. You can specify the service
definition and implement your service either in Java/Groovy/XML(Minilang).
Services in OFBiz are session-less, so if you wish to do handling of
HttpSession object then you need to do it in the Events.
All these things are very well explained in the tutorial link which I have
shared above. There is also a very good reference available for the
comparison between Events and Services. Please take a look at it.
Thank you.
