Attributes should be declared at start-state level or task-node level

In our scenario we need to set the process level attributes at the creation of processInstance


Can any body help me for this solution


Scenario:


*In JPDL we are defining the attributes at the start-state tag with task tag
but we dont require to define with task tag

*With out tag we can define the process level attributes or not

*Is there any possibility of doing with out task tag


Thanks,
Suresh
