Package javax.mail
The JavaMailTM API provides classes that model a mail system.See: Description
Interface Summary | |
---|---|
MessageAware | An interface optionally implemented by DataSources to
supply information to a DataContentHandler about the
message context in which the data content object is operating. |
MultipartDataSource | MultipartDataSource is a DataSource that contains body
parts. |
Part | The Part interface is the common base interface for
Messages and BodyParts. |
QuotaAwareStore | An interface implemented by Stores that support quotas. |
UIDFolder | The UIDFolder interface is implemented by Folders
that can support the "disconnected" mode of operation, by providing
unique-ids for messages in the folder. |
Class Summary | |
---|---|
Address | This abstract class models the addresses in a message. |
Authenticator | The class Authenticator represents an object that knows how to obtain authentication for a network connection. |
BodyPart | This class models a Part that is contained within a Multipart. |
FetchProfile | Clients use a FetchProfile to list the Message attributes that it wishes to prefetch from the server for a range of messages. |
FetchProfile.Item | This inner class is the base class of all items that can be requested in a FetchProfile. |
Flags | The Flags class represents the set of flags on a Message. |
Flags.Flag | This inner class represents an individual system flag. |
Folder | Folder is an abstract class that represents a folder for mail messages. |
Header | The Header class stores a name/value pair to represent headers. |
Message | This class models an email message. |
Message.RecipientType | This inner class defines the types of recipients allowed by the Message class. |
MessageContext | The context in which a piece of Message content is contained. |
Multipart | Multipart is a container that holds multiple body parts. |
PasswordAuthentication | The class PasswordAuthentication is a data holder that is used by Authenticator. |
Provider | The Provider is a class that describes a protocol implementation. |
Provider.Type | This inner class defines the Provider type. |
Quota | This class represents a set of quotas for a given quota root. |
Quota.Resource | An individual resource in a quota root. |
Service | An abstract class that contains the functionality common to messaging services, such as stores and transports. |
Session | The Session class represents a mail session and is not subclassed. |
Store | An abstract class that models a message store and its access protocol, for storing and retrieving messages. |
Transport | An abstract class that models a message transport. |
UIDFolder.FetchProfileItem | A fetch profile item for fetching UIDs. |
URLName | The name of a URL. |
Exception Summary | |
---|---|
AuthenticationFailedException | This exception is thrown when the connect method on a Store or Transport object fails due to an authentication failure (e.g., bad user name or password). |
FolderClosedException | This exception is thrown when a method is invoked on a Messaging object and the Folder that owns that object has died due to some reason. |
FolderNotFoundException | This exception is thrown by Folder methods, when those methods are invoked on a non existent folder. |
IllegalWriteException | The exception thrown when a write is attempted on a read-only attribute of any Messaging object. |
MessageRemovedException | The exception thrown when an invalid method is invoked on an expunged Message. |
MessagingException | The base class for all exceptions thrown by the Messaging classes |
MethodNotSupportedException | The exception thrown when a method is not supported by the implementation |
NoSuchProviderException | This exception is thrown when Session attempts to instantiate a Provider that doesn't exist. |
ReadOnlyFolderException | This exception is thrown when an attempt is made to open a folder read-write access when the folder is marked read-only. |
SendFailedException | This exception is thrown when the message cannot be sent. |
StoreClosedException | This exception is thrown when a method is invoked on a Messaging object and the Store that owns that object has died due to some reason. |
Package javax.mail Description
The JavaMailTM API
provides classes that model a mail system.
The javax.mail
package defines classes that are common to
all mail systems.
The javax.mail.internet
package defines classes that are specific
to mail systems based on internet standards such as MIME, SMTP, POP3, and IMAP.
The JavaMail API includes the javax.mail
package and subpackages.
For an overview of the JavaMail API, read the JavaMail specification included in the download bundle or available on the JavaMail web site.
The code to send a plain text message can be as simple as the following:
Properties props = new Properties(); props.put("mail.smtp.host", "my-mail-server"); props.put("mail.from", "[email protected]"); Session session = Session.getInstance(props, null); try { MimeMessage msg = new MimeMessage(session); msg.setFrom(); msg.setRecipients(Message.RecipientType.TO, "[email protected]"); msg.setSubject("JavaMail hello world example"); msg.setSentDate(new Date()); msg.setText("Hello, world!\n"); Transport.send(msg); } catch (MessagingException mex) { System.out.println("send failed, exception: " + mex); }The JavaMail download bundle contains many more complete examples in the "demo" directory.
Don't forget to see the JavaMail API FAQ for answers to the most common questions. The JavaMail web site contains many additional resources.
The JavaMail API supports the following standard properties,
which may be set in the Session
object, or in the
Properties
object used to create the Session
object.
The properties are always set as strings; the Type column describes
how the string is interpreted. For example, use
props.put("mail.debug", "true");to set the
mail.debug
property, which is of type boolean.
Name | Type | Description |
---|---|---|
mail.debug | boolean | The initial debug mode. Default is false. |
mail.from | String |
The return email address of the current user, used by the
InternetAddress method getLocalAddress .
|
mail.mime.address.strict | boolean |
The MimeMessage class uses the InternetAddress method
parseHeader to parse headers in messages. This property
controls the strict flag passed to the parseHeader
method. The default is true.
|
mail.host | String |
The default host name of the mail server for both Stores and Transports.
Used if the mail.protocol.host property isn't set.
|
mail.store.protocol | String |
Specifies the default message access protocol. The
Session method getStore() returns a Store
object that implements this protocol. By default the first Store
provider in the configuration files is returned.
|
mail.transport.protocol | String |
Specifies the default message access protocol. The
Session method getTransport() returns a Transport
object that implements this protocol. By default the first Transport
provider in the configuration files is returned.
|
mail.user | String |
The default user name to use when connecting to the mail server.
Used if the mail.protocol.user property isn't set.
|
mail.protocol.class | String | Specifies the fully qualified class name of the provider for the specified protocol. Used in cases where more than one provider for a given protocol exists; this property can be used to specify which provider to use by default. The provider must still be listed in a configuration file. |
mail.protocol.host | String |
The host name of the mail server for the specified protocol.
Overrides the mail.host property.
|
mail.protocol.port | int | The port number of the mail server for the specified protocol. If not specified the protocol's default port number is used. |
mail.protocol.user | String |
The user name to use when connecting to mail servers
using the specified protocol.
Overrides the mail.user property.
|
The JavaMail API also supports several System properties;
see the javax.mail.internet
package documentation
for details.
The JavaMail reference
implementation from Sun includes protocol providers in subpackages of
com.sun.mail
. Note that the APIs to these protocol
providers are not part of the standard JavaMail API. Portable
programs will not use these APIs.
Nonportable programs may use the APIs of the Sun protocol providers
by (for example) casting a returned Folder
object to a
com.sun.mail.imap.IMAPFolder
object. Similarly for
Store
and Message
objects returned from the
standard JavaMail APIs.
The Sun protocol providers also support properties that are specific to
those providers. The package documentation for the
IMAP
, POP3
,
and SMTP
packages provide details.
