Event Releted Question
Can we call multiple services one after another as part of controller request-map entry
<request-map uri="createPracticePersonJavaEvent">
<security https="false" auth="true"/>
<event type="java" path="org.hotwax.mypractice.PracticeEvents" invoke="createPracticePersonJavaEvent"/>
<event type="java" path="org.hotwax.mypractice.PracticeEvents" invoke="createPracticePersonJavaEvent1"/>
<response name="success" type="view" value="CreatePracticePersonEventJ"/>
<response name="error" type="view" value="CreatePracticePersonEventJ"/>
</request-map>
The xsd allows this, but what should the first service return for the second event to be called. And how will this work if the first event is of type simple

You have three options (that come to mind):
1. You can chain request-maps together to call multiple events by using "request" typed response element.
2. You can call a single service which in turn calls two services, basically a wrapper.
3. You can use a service group which is essentially a shortcut for #2
You can find examples for 1 and 3 in the source code so I'm not going to explain them here unless you have specific questions. (#2 doesn't really need explaining)

You don't have to use view-map with screenfop type in order to generate. You
need that only if you want to return a pdf as response. Instead you should
use a service to generate the pdf and store it in a file. As a reference
for pdf generation you can check the pdf printing functionality order
manager.

No, No.

Just added another request map, which is called in case of success of
previous service (where u create save the pdf) and call the service to do DB
operations.
Return json instead of a screen and view-map

You don't need that

Some Scenario
Posted by Deepa Priolkar <de...@TechMahindra.com>.
I have a scenario which is to do the following
The web browser will call the server via ajax. At the server the system should produce a pdf file and store it in the file system. Next make a database update and return some data back to web browser using json
Below is the steps as per my understanding to do the same
· Front end to call a controller entry for a particular request map
· Request map to call a service and do some things and then kick off the view map of type screenfop to generate pdf.
· This screen fop is mapped to custom handler based on org.ofbiz.widget.screen.ScreenFopViewHandler which has code tweaked to store the pdf as file on hard disk and then call another request map entry in the controller.xml
· This request map to do the rest of things like update database row and then return data in json back to client
Is there a better way to execute the above scenario
Secondly from my customer ScreenFopViewHandler how do I call another request map entry in controller.xml. Will it via RequestDispatcher?
