Class AFormProcessingServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

de.xima.fc.servlet.AFormProcessingServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

Direct Known Subclasses:

FormProcessServlet, FormVerifyServlet, InboxWorkflowServlet

public abstract class AFormProcessingServlet
extends javax.servlet.http.HttpServlet

Base class for workflow-servtes. They both need to initiate the workflow, with the main difference being that the former allows skipping workflow actions and setting a different state on the form. This requires special permissions. To make it easier to check for the appropriate permissions, these two servlet were separated.
