AConnectionFactory
object encapsulates a set of connection configuration parameters that has been defined by an administrator. A client uses it to create a connection with a Jakarta Messaging provider.A
ConnectionFactory
object is a Jakarta Messaging administered object and supports concurrent use.Jakarta Messaging administered objects are objects containing configuration information that are created by an administrator and later used by Jakarta Messaging clients. They make it practical to administer the Jakarta Messaging API in the enterprise.
Although the interfaces for administered objects do not explicitly depend on the Java Naming and Directory Interface (JNDI) API, the Jakarta Messaging API establishes the convention that Jakarta Messaging clients find administered objects by looking them up in a JNDI namespace.
An administrator can place an administered object anywhere in a namespace. The Jakarta Messaging API does not define a naming policy.
It is expected that Jakarta Messaging providers will provide the tools an administrator needs to create and configure administered objects in a JNDI namespace. Jakarta Messaging provider implementations of administered objects should be both
javax.jndi.Referenceable
andjava.io.Serializable
so that they can be stored in all JNDI naming contexts. In addition, it is recommended that these implementations follow the JavaBeansTM design patterns.This strategy provides several benefits:
- It hides provider-specific details from Jakarta Messaging clients.
- It abstracts administrative information into objects in the Java programming language ("Java objects") that are easily organized and administered from a common management console.
- Since there will be JNDI providers for all popular naming services, this means that Jakarta Messaging providers can deliver one implementation of administered objects that will run everywhere.
An administered object should not hold on to any remote resources. Its lookup should not use remote resources other than those used by the JNDI API itself.
Clients should think of administered objects as local Java objects. Looking them up should not have any hidden side effects or use surprising amounts of local resources.

Method Detail
-
createConnection
Connection createConnection() throws JMSException
Creates a connection with the default user identity. The connection is created in stopped mode. No messages will be delivered until theConnection.start
method is explicitly called.- Returns:
- a newly created connection
- Throws:
JMSException
- if the Jakarta Messaging provider fails to create the connection due to some internal error.JMSSecurityException
- if client authentication fails due to an invalid user name or password.- Since:
- JMS 1.1
-
createConnection
Connection createConnection(String userName, String password) throws JMSException
Creates a connection with the specified user identity. The connection is created in stopped mode. No messages will be delivered until theConnection.start
method is explicitly called.- Parameters:
userName
- the caller's user namepassword
- the caller's password- Returns:
- a newly created connection
- Throws:
JMSException
- if the Jakarta Messaging provider fails to create the connection due to some internal error.JMSSecurityException
- if client authentication fails due to an invalid user name or password.- Since:
- JMS 1.1
-
createContext
JMSContext createContext()
Creates a JMSContext with the default user identity and an unspecified sessionMode.A connection and session are created for use by the new JMSContext. The connection is created in stopped mode but will be automatically started when a JMSConsumer is created.
The behaviour of the session that is created depends on whether this method is called in a Java SE environment, in the Jakarta EE application client container, or in the Jakarta EE web or EJB container. If this method is called in the Jakarta EE web or EJB container then the behaviour of the session also depends on whether or not there is an active JTA transaction in progress.
In a Java SE environment or in the Jakarta EE application client container:
- The session will be non-transacted and received messages will be acknowledged automatically using an
acknowledgement mode of
JMSContext.AUTO_ACKNOWLEDGE
For a definition of the meaning of this acknowledgement mode see the link below.
In a Jakarta EE web or EJB container, when there is an active JTA transaction in progress:
- The session will participate in the JTA transaction and will be committed or rolled back when that transaction is
committed or rolled back, not by calling the
JMSContext
'scommit
orrollback
methods.
In the Jakarta EE web or EJB container, when there is no active JTA transaction in progress:
- The session will be non-transacted and received messages will be acknowledged automatically using an
acknowledgement mode of
JMSContext.AUTO_ACKNOWLEDGE
For a definition of the meaning of this acknowledgement mode see the link below.
- Returns:
- a newly created JMSContext
- Throws:
JMSRuntimeException
- if the Jakarta Messaging provider fails to create the JMSContext due to some internal error.JMSSecurityRuntimeException
- if client authentication fails due to an invalid user name or password.- Since:

JMSContext createContext(String userName, String password)
Creates a JMSContext with the specified user identity and an unspecified sessionMode.A connection and session are created for use by the new JMSContext. The connection is created in stopped mode but will be automatically started when a JMSConsumer.
The behaviour of the session that is created depends on whether this method is called in a Java SE environment, in the Jakarta EE application client container, or in the Jakarta EE web or EJB container. If this method is called in the Jakarta EE web or EJB container then the behaviour of the session also depends on whether or not there is an active JTA transaction in progress.
In a Java SE environment or in the Jakarta EE application client container:
- The session will be non-transacted and received messages will be acknowledged automatically using an
acknowledgement mode of
JMSContext.AUTO_ACKNOWLEDGE
For a definition of the meaning of this acknowledgement mode see the link below.
In a Jakarta EE web or EJB container, when there is an active JTA transaction in progress:
- The session will participate in the JTA transaction and will be committed or rolled back when that transaction is
committed or rolled back, not by calling the
JMSContext
'scommit
orrollback
methods.
In the Jakarta EE web or EJB container, when there is no active JTA transaction in progress:
- The session will be non-transacted and received messages will be acknowledged automatically using an
acknowledgement mode of
JMSContext.AUTO_ACKNOWLEDGE

JMSContext createContext(String userName, String password, int sessionMode)
Creates a JMSContext with the specified user identity and the specified session mode.A connection and session are created for use by the new JMSContext. The JMSContext is created in stopped mode but will be automatically started when a JMSConsumer is created.
The effect of setting the
sessionMode
argument depends on whether this method is called in a Java SE environment, in the Jakarta EE application client container, or in the Jakarta EE web or EJB container. If this method is called in the Jakarta EE web or EJB container then the effect of setting thesessionMode
argument also depends on whether or not there is an active JTA transaction in progress.In a Java SE environment or in the Jakarta EE application client container:
- If
sessionMode
is set toJMSContext.SESSION_TRANSACTED
then the session will use a local transaction which may subsequently be committed or rolled back by calling theJMSContext
'scommit
orrollback
methods. - If
sessionMode
is set to any ofJMSContext.CLIENT_ACKNOWLEDGE
,JMSContext.AUTO_ACKNOWLEDGE
orJMSContext.DUPS_OK_ACKNOWLEDGE
. then the session will be non-transacted and messages received by this session will be acknowledged according to the value ofsessionMode
. For a definition of the meaning of these acknowledgement modes see the links below.
In a Jakarta EE web or EJB container, when there is an active JTA transaction in progress:
- The argument
sessionMode
is ignored. The session will participate in the JTA transaction and will be committed or rolled back when that transaction is committed or rolled back, not by calling theJMSContext
'scommit

methods. Since the argument is ignored, developers are recommended to usecreateContext(String userName, String password)
instead of this method.
In the Jakarta EE web or EJB container, when there is no active JTA transaction in progress:
- The argument
acknowledgeMode
must be set to either ofJMSContext.AUTO_ACKNOWLEDGE
