A.3.1 Additional Servlets

If non-blank, this is a whitespace-separated list of Java class names. Each class name is a custom
class that extends javax.servlet.http.HttpServer. Custom servlets can be used to extend the
functionality of the Publisher channel Web server.
Additional information about custom servlets is available in
Publisher Channel," on page
A.4 Subscriber Channel Policies
The configuration of the Subscriber channel policies depends on what a particular installation wants
to accomplish with the Manual Task Service driver. However, there are certain guidelines that might
be helpful.
In general, the best place to construct a <
Transformation policy. The reason for this is that most Metadirectory engine processing has been
completed by the time commands reach the Command Transformation policy. This means that
Create policies have been processed for Add events (allowing vetoing of Add events for objects that
don't have all the attributes necessary for constructing the e-mail, for example). This also means that
Modify events for objects without associations have already been converted to Add events.
The XSLT style sheet that constructs the e-mail message might or might not need to query
eDirectory for additional information.
For example, if the e-mail message is simply a welcome message to a new employee, the Add
command can contain all the information necessary: Given Name, Surname, and Internet E-mail
Address. This is accomplished by specifying in the Create policy that Given Name, Surname, and
Internet E-mail Address are required attributes. This ensures that only add commands that contain
the necessary information can reach the Command Transformation.
However, if the e-mail message is a message to the manager of an employee, the style sheet needs to
query eDirectory. The manager DN can be obtained from the Add event for the employee's User
object, but a query must be made to obtain the manager's e-mail address because that information is
an attribute of the manager's User object.
In addition, if e-mail notifications are being generated as the result of Modify commands for objects
that are associated with the driver, queries must be made to obtain information not contained in the
modify command.

A.4.1 Blocking Commands from Reaching the Subscriber
Channel
If e-mail messages are to be generated from events other than Add events, the Add events must be
allowed to reach the Subscriber channel for those objects that are to be monitored. Allowing Add
events to reach the Subscriber channel results in a generated association value being returned to
Identity Manager from the Subscriber channel.
