<div class="jive-rendered-content"><p>hi ,</p><p>I am new to workflow. Appreciate any pointers on this design question. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>1. is it normal or best practice to design workflows such that they can be run with UI input supplementing the data and also the workflow can be run as a batch job with data supplied to the workflow by non UI means ? </p><p>   If so, should I have script tasks which will undertake UI handling when run in the UI context and pull the data by some other means [xml, db etc] when run in batch mode ? </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>  In general when you design a workflow, is it the case that you almost always know at design time whether you are going to have certain action hnalded by user or some other script ?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>2. In my problem, I have some backend java objects that do the actual work. I need to call a specific method on them as part of my workflow actions. When I use "script task" and java as the script option, the designer takes the java code snippet. can I do something like this : </p><p>     Service service = ServiceLocator.getService("some identifier");</p><p>     // access some state data from the workflow</p><p>     service.invoke("data retrieved from workflow");</p><p>    Is this the correct usage ?</p><p>    Is there a standard interface that jbpm would recognise that my service objects can implement , thereby , my service objects are first class workflow handlers. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>appreciate any help.</p><p>thanks</p><p>Joe</p></div>
