Special thanks to Mridul Pathak for inspiring me to write this tutorial. 

This  This document is meant for OFBiz  beginners. It will help to come up with the most basic knowledge of OFBiz application development process. Aim behind the creation of this tutorial is to acquaint a developer with best practices, coding conventions and the control flow.

Step - 4 : Show labels in screens above the form like "New Person --- Simple Event"  and  "New Person --- Java Event" so that it will be easy to identify the purpose of that form.

...

Step - 2 :  Now you have to create a file by name "eecas.xml" in "entitydef" directory, which will be in your component directory "practice". Eeca definition will come here. (Take reference from eecas.xml of "accounting" component). This will be :

    <!-- To create party role whenever a party is created -->
    <eca entity="Party" operation="create" event="return">
        <condition field-name="partyId" operator="is-not-empty"/>
        <action service="createPartyRoleCustomer" mode="sync"/>
    </eca>

...

 Create a group service by name "partyGroup" like :

<!- - Group service -->
    <service name="partyGroup" engine="group" auth="true">
        <description>Creates a party, person and party role Client</description>
        <group>
            <invoke name="createPracticePerson" result-to-context="true"/>
            <invoke name="createPartyRoleClient"/>
        </group>
    </service>

...

Step - 2 : Create new screen, form and service for creating a person. Here service will implement the interface. (For creating interface take reference from services_fixedasset.xml of accounting component) it will be like :

<!- - Peson Interface - ->
    <service name="createPersonInterface" engine="interface" location="" invoke="">
        <attribute name="firstName" mode="IN" type="String" optional="false"/>
        <attribute name="middleName" mode="IN" type="String" optional="true"/>
        <attribute name="lastName" mode="IN" type="String" optional="false"/>
        <attribute name="suffix" mode="IN" type="String" optional="true"/>
    </service>
   
    <service name="createPracticePersonInterfaceService" engine="simple" location="org/hotwax/practice/PracticeServices.xml" invoke="createPracticePersonInterfaceService" auth="false">
        <description>Creates a new Person</description>
        <implements service="createPersonInterface"/>
        <attribute name="partyId" mode="OUT" type="String" optional="false"/>  
        <override name="suffix" optional="false"/>
    </service>
