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 servlets. 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.
