All Implemented Interfaces:

Cloneable, ErrorFinalizing, Initializable, PropertySupplying, ResourceSupplying

public class MailFinalizer
extends AbstractErrorFinalizer

Handles error-notification by e-mail. The properties of the finalizer define whether it may be used for local or remote mail reporting, according to the error-event follow-ups ErrorEvent.MAIL_LOCAL and ErrorEvent.MAIL_HOME. Note that the type of error handled is defined in the KEY_FOLLOWUP property, in principle there is no difference in mailing to a local or remote person, except that the KEY_TO fields should differ.
The message sent back has the error event class name in its subject and the entire message in its body part. The sent date of the mail is set to the construction time of the error event.

This class relies on the mailin API provided by Sun. Ensure that the required extension, at time of writing mail.jar and activation.jar are in the CLASSPATH.

Method Summary

Modifier and Type	Method and Description
boolean	finalizeError(TargetDefinition ignore, ErrorEvent occur, CommandLaunching[] servers, Sequencing<?> dummy, ParameterClustering set) Handles a send-mail error follow-up.
String	getFollowUp() Returns the follow-up this finalizer deals with.
void	init() On init, we try to parse the from field.
boolean	isFinalizing() This error finalizer is threadless, so it's finalizeError(target.TargetDefinition, stella.ErrorEvent, stella.CommandLaunching[], stella.Sequencing<?>, stella.ParameterClustering) method is blocking.

Constructor Detail

MailFinalizer

public MailFinalizer(Map<String,String> prop)

Constructs a new mail-finalizer with the distinct properties. Make sure that the KEY_FOLLOWUP, the KEY_TO and the #KEY_SMTPHOST are present. The latter key's value is directly copied to the JavaMail required property mail.smtp.kost.

For efficiency, the mail session is initialized at finalizer construction, while the actual mail-transportation is done on error finalizing.

We use my properties to construct the Mailer instance to use.

Method Detail

init

public void init()

On init, we try to parse the from field. If that fails, we throw an IllegalArgumentException. We do not check, if a to-field exists, this is checked during error finalizing.

Specified by:

init in interface Initializable

Overrides:

init in class AbstractErrorFinalizer

getFollowUp

public String getFollowUp()

Returns the follow-up this finalizer deals with.

finalizeError

public boolean finalizeError(TargetDefinition ignore,
                             ErrorEvent occur,
                             CommandLaunching[] servers,
                             Sequencing<?> dummy,
                             ParameterClustering set)

Handles a send-mail error follow-up. The recipient list is derived from the appropriate KEY_TO, KEY_CC, and KEY_BCC keys, the mail subject is the class name of the error and the mail body the human-readable part of the error. The mail date is set to the error- occurence date. If the mail was sent correctly, true is returned.

isFinalizing

public boolean isFinalizing()

This error finalizer is threadless, so it's finalizeError(target.TargetDefinition, stella.ErrorEvent, stella.CommandLaunching[], stella.Sequencing<?>, stella.ParameterClustering) method is blocking. This method always returns false.
