Business Process Context and JBPM Process Variables

[coolex]

Hello!

Is there any difference between the Business Process Variables I define in my process definition like:

<task name="This is my Task" swimlane="xyz">
               <description>
                    Description of Task
               </description>
               <controller>
                    <variable access="read,write" name="variable1"></variable>
                    <variable access="read,write" name="variable2"></variable>
               </controller>
</task>

and variables I define in my POJO classes with the help of Business Process Context Annotations like:

@Out(scope=ScopeType.BUSINESS_PROCESS, required=false)
String variable1;
@Out(scope=ScopeType.BUSINESS_PROCESS, required=false)
String variable2;

Or maybe there is no difference?

Thanks.
Axel

So, as I understand the first alternative is related to a form you can generate for the process. The variables in the second variant are not related to a special form but can be used anywhere in process.

Are you sure?
Does anybody else have an idea about the connection of Business Process Context and JBPM Process Variables? I mean using

@Out(scope=ScopeType.BUSINESS_PROCESS, required=false)
String variable1;

is it the same like

<controller>
    <variable access="read,write" name="variable1"></variable>
</controller>

in a process definition?
Please help me to get an idea.
