public class SMTPTargetFactory

extends AbstractTargetFactory

SMTPTargetFactory class.

This factory creates SMTPOutputLogTarget's. It uses the context-key attribute to locate the required JavaMail Session from the Context object passed to this factory. The default context-key is session-context.

 <smtp id="target-id" context-key="context-key-to-session-object">
   <format type="raw|pattern|extended">pattern to be used if needed</format>
   <to>address-1@host</to>
   <to>address-N@host</to>
   <from>address@host</from>
   <subject>subject line</subject>
   <maximum-size>number</maximum-size>
   <maximum-delay-time>seconds</maximum-delay-time>
 </smtp>
 

The Factory will look for a javax.mail.Session instance in the Context using the specified context-key. If your needs are simple, then it is also possible to define a Session within the configuration by replacing the context-key attribute with a session child element as follows:

 <session>
   <parameter name="mail.host" value="mail.apache.com"/>
 </session>
 

The Session is created by calling Session.getInstance, providing a Properties object whose values are defined in the above block. Any valid name value pair can be specified.

<format>

The type attribute of the pattern element denotes the type of Formatter to be used and according to it the pattern to use for. This elements defaults to:

%7.7{priority} %5.5{time} [%8.8{category}] (%{context}): %{message}\\n%{throwable}

public SMTPTargetFactory()

Method Detail

createTarget

public final LogTarget createTarget(Configuration config)
                             throws ConfigurationException

Creates an SMTPOutputLogTarget based on a Configuration

Parameters:

config - a Configuration instance

Returns:

LogTarget instance

Throws:

ConfigurationException - if an error occurs

getFormatter

protected Formatter getFormatter(Configuration config)

Helper method to obtain a formatter for this factory.

Parameters:

config - a Configuration instance

Returns:

a Formatter instance

getSession

protected javax.mail.Session getSession(Configuration config)
                                 throws ContextException,
                                        ConfigurationException

Helper method to create a JavaMail Session object. If your session object has simple needs, you can nest a configuration element named session containing name-value pairs that are passed to Session.getInstance(). If no configuration is found, a Session will be loaded from this factory's context object. You can override this method if you need ot obtain the JavaMail session using some other means.

Returns:

JavaMail Session instance

Throws:

ContextException - if an error occurs

ConfigurationException - if invalid session configuration

createAddress

protected javax.mail.Address createAddress(java.lang.String address)
                                    throws javax.mail.internet.AddressException

Helper factory method to create a new Address object. Override this method in a subclass if you wish to create other Address types rather than InternetAddress (eg. NewsAddress)

Parameters:

address - address string from configuration

Returns:

an Address object

Throws:

javax.mail.internet.AddressException - if an error occurs
