hi, all
I haved designed one student screen
i can able to enter ID and Save it.
now before saving the record i want to check that the ID is present or
not (duplicate ID)
and then i want to save it otherwise throw an error that 'Code already exists.'
how to do this?

Thanks
Vinayak

it is really important you look through the code to find these answers.
there are many examples.
it will also get you familiar with how ofbiz works.

First, you need an event on request-map (controller) that match your
sent uri
After you define a java service.

If you know service and controller and if the engine of your service is
java you can use this :

*****
GenericValue myObject = delegator.findByPrimaryKey("MyObject",
UtilMisc.toMap("id", id));
if (UtilValidate.isNotEmpty(myObject)) return ServiceUtil.returnError(
"id already exist");

myObject = delegator.makeValidValue("MyObject", context);
myObject.create();
******

It's the greate line ;)

just to clarify ofbiz does not use objects but entities.
so you should use MyEntity

The problem has been resolved, i have to include the following library

import org.ofbiz.service.ServiceUtil;

now how to show or display the error message  to the user

[BJ Freeman]

in the controller that called this, the return would be an error
check the controller.xml for error.jsp.

unless your using the action section of the widgets.
then you can use the conditions
look for
<if-compare field-name=

you can only do that in ofbiz, if your using javascript.
other wise you need to use the controller.xml a request-map to call you
code and and request-views to display the results.
this is covered in the videos, specifically #7
