Java Service Classes

[Prabhakar Pandey]

Here is a snippet of my controller.xml

*<request-map uri="submit">
        <security https="false" auth="false" />
            <event type="java" path="org.mindtree.testapp.EmployeeEvents"
invoke="createEmployee"/>
            <event type="java" path="org.mindtree.testapp.EmployeeEvents"
invoke="viewEmployee"/>
            <response name="success" type="view" value="main" />
    </request-map>
*
can i have two events in it? and through Employee Events i am calling
viewEmployeeService in a EmployeeServices.java where i am getting values
from database and storing them in map.
while i am calling from service name from *EmployeeEvents *can i directly
call runsync without sending any map.??

Thanks

Hi Prabhakar,

The scenario you are given is not properly executed because, in this
case the second event(viewEmployee) doesn't works for either success or
failure of  event(createEmployee). Thus to successfully execute this you
have to provide response 'type=request' for first event which on success
invoke's another requests and executes second event, and on success of
it the response goes to specified view.

e.g:
<request-map uri="submit">
<security https="false" auth="false" />
<event type="java" path="org.mindtree.testapp.EmployeeEvents"
invoke="createEmployee"/>
<response name="success" type="request" value="submitSecond" />
</request-map>

<request-map uri="submitSecond">
<security https="false" auth="false" />
<event type="java" path="org.mindtree.testapp.EmployeeEvents"
invoke="viewEmployee"/>
<response name="success" type="view" value="main" />
</request-map>

Thanks&  regards

hi Prabhakar,
      In this scenario , your second event will not get executed because
after getting response success(or error) from first event it will not
return back to call the second event.
For achieving required functionality you can use response
type="request-redirect" in your first response
e.g

<request-map uri="submit">
         <security https="false" auth="false" />
             <event type="java" path="org.mindtree.testapp.EmployeeEvents"
invoke="createEmployee"/>
             <response name="success" type="request-redirect" value="submitAgain" />
     </request-map>

<request-map uri="submitAgain">
         <security https="false" auth="false" />
             <event type="java" path="org.mindtree.testapp.EmployeeEvents"
invoke="viewEmployee"/>
             <response name="success" type="view" value="main" />
     </request-map>

Prabhakar,

      You can't call runSync in this way because it is wrong
syntactically, you have to pass map as parameter while calling runSync.
Also you can pass empty map as parameter but in this case service will
return error : "IN parameter is missing".

Why dont you use "service-groups"

with that you can call a bundle of services, which run all together with just one call..


steps to archieve it:

1. create  a service group xml definition file
2. add this file into your ofbiz-component.xml
3. add the group element to your service group def. file (including all invokes you want to have)
4. call this service group out of your controller - request mapping

thats it.

Thanks everyone.
i want to fetch data from a table.
so how can i implement it using java event class and java service class i.e
first i go to event class and then call the service class so get the data?

This is really much to describe in detail. this is sth of the base understanding in ofbiz, with that understanding you can do most of the things...

so I please you to read the following:

http://www.amazon.de/Apache-Ofbiz-Cookbook-Ruth-Hoffman/dp/1847199186/ref=sr_1_cc_2?s=aps&ie=UTF8&qid=1342433161&sr=1-2-catcorr

there are good descriptions like how to's with examples and so on. If you really want to get steps forward with ofbiz, this is a must have for beginners!

It is not, cause we dont want to write the details down, its because otherwise you do not get the important base understanding...at the end, you save time with that!

Kindly

Robert

there are two different ways depending oh what you trying to do.
when you have data coming from a webpage you want process, use a event
or service to process the data. I suggest mini lang since it takes a lot
of coding out of the process.

when you want to display information you use the groovy to marshal the
data then pass it to the FTL to be rendered.

PS. if is best if you join the ofbiz mailing and include past
conversations so we can get a sense without hunting through the mailing
list.
