Sorting Workflow Inbox by priority

I’m trying to sort the workflow inbox HTML page as per the priority and not the create date. I checked the Workflow User’s Guide and found that I have to add the property
com.wm.zesus.pd.client.servlet.inboxSortBy=<priority/name/description/date>
to the process that hosts the servlet.

I don’t know how to find this process. Any idea what it could be ?

Please can any one let me know.

Thanks,

Abhijeet
