| <div class="block">Creates an unshared durable subscription on the specified topic (if one does not already exist) and creates a |
| consumer on that durable subscription. This method creates the durable subscription without a message selector and |
| with a <code>noLocal</code> value of <code>false</code>. |
| |
| <p> |
| A durable subscription is used by an application which needs to receive all the messages published on a topic, |
| including the ones published when there is no active consumer associated with it. The Jakarta Messaging provider retains a record |
| of this durable subscription and ensures that all messages from the topic's publishers are retained until they are |
| delivered to, and acknowledged by, a consumer on this durable subscription or until they have expired. |
| |
| <p> |
| A durable subscription will continue to accumulate messages until it is deleted using the <code>unsubscribe</code> method. |
| |
| <p> |
| This method may only be used with non-shared durable subscriptions. Any durable subscription created using this |
| method will be non-shared. This means that only one active (i.e. not closed) consumer on the subscription may exist |
| at a time. The term "consumer" here means a <code>TopicSubscriber</code>, <code>MessageConsumer</code> or <code>JMSConsumer</code> |
| object in any client. |
| |
| <p> |
| An unshared durable subscription is identified by a name specified by the client and by the client identifier, which |
| must be set. An application which subsequently wishes to create a consumer on that non-shared durable subscription |
| must use the same client identifier. |
| |
| <p> |
| If an unshared durable subscription already exists with the same name and client identifier and the same topic and |
| message selector, and there is no consumer already active (i.e. not closed) on the durable subscription, and no |
| consumed messages from that subscription are still part of a pending transaction or are not yet acknowledged in the |
| session, then this method creates a <code>TopicSubscriber</code> on the existing durable subscription. |
| |
| <p> |
| If an unshared durable subscription already exists with the same name and client identifier, and there is a consumer |
| already active (i.e. not closed) on the durable subscription, or consumed messages from that subscription are still |
| part of a pending transaction or are not yet acknowledged in the session, then a <code>JMSException</code> will be thrown. |
| |
| <p> |
| If an unshared durable subscription already exists with the same name and client identifier but a different topic, |
| message selector or <code>noLocal</code> value has been specified, and there is no consumer already active (i.e. not |
| closed) on the durable subscription, and no consumed messages from that subscription are still part of a pending |
| transaction or are not yet acknowledged in the session, then the durable subscription will be deleted and a new one |
| created. |
| |
| <p> |
| A shared durable subscription and an unshared durable subscription may not have the same name and client identifier. |
| If a shared durable subscription already exists with the same name and client identifier then a <code>JMSException</code> |
| is thrown. |
| |
| <p> |
| There is no restriction on durable subscriptions and shared non-durable subscriptions having the same name and |
| clientId. Such subscriptions would be completely separate. |
| |
| <p> |
| This method is identical to the corresponding <code>createDurableConsumer</code> method except that it returns a |

| <pre><a href="../../jakarta/jms/TopicSubscriber.html" title="interface in jakarta.jms">TopicSubscriber</a> createDurableSubscriber(<a href="../../jakarta/jms/Topic.html" title="interface in jakarta.jms">Topic</a> topic, |

| <div class="block">Creates an unshared durable subscription on the specified topic (if one does not already exist), specifying a message |
| selector and the <code>noLocal</code> parameter, and creates a consumer on that durable subscription. |
| |
| <p> |
| A durable subscription is used by an application which needs to receive all the messages published on a topic, |
| including the ones published when there is no active consumer associated with it. The Jakarta Messaging provider retains a record |
| of this durable subscription and ensures that all messages from the topic's publishers are retained until they are |
| delivered to, and acknowledged by, a consumer on this durable subscription or until they have expired. |
| |
| <p> |
| A durable subscription will continue to accumulate messages until it is deleted using the <code>unsubscribe</code> method. |
| |
| <p> |
| This method may only be used with non-shared durable subscriptions. Any durable subscription created using this |
| method will be non-shared. This means that only one active (i.e. not closed) consumer on the subscription may exist |
| at a time. The term "consumer" here means a <code>TopicSubscriber</code>, <code>MessageConsumer</code> or <code>JMSConsumer</code> |
| object in any client. |
| |
| <p> |
| An unshared durable subscription is identified by a name specified by the client and by the client identifier, which |
| must be set. An application which subsequently wishes to create a consumer on that non-shared durable subscription |
| must use the same client identifier. |
| |
| <p> |
| If an unshared durable subscription already exists with the same name and client identifier and the same topic and |
| message selector, and there is no consumer already active (i.e. not closed) on the durable subscription, and no |
| consumed messages from that subscription are still part of a pending transaction or are not yet acknowledged in the |
| session, then this method creates a <code>TopicSubscriber</code> on the existing durable subscription. |
| |
| <p> |
| If an unshared durable subscription already exists with the same name and client identifier, and there is a consumer |
| already active (i.e. not closed) on the durable subscription, or consumed messages from that subscription are still |
| part of a pending transaction or are not yet acknowledged in the session, then a <code>JMSException</code> will be thrown. |
| |
| <p> |
| If an unshared durable subscription already exists with the same name and client identifier but a different topic, |
| message selector or <code>noLocal</code> value has been specified, and there is no consumer already active (i.e. not |
| closed) on the durable subscription, and no consumed messages from that subscription are still part of a pending |
| transaction or are not yet acknowledged in the session, then the durable subscription will be deleted and a new one |
| created. |
| |
| <p> |
| A shared durable subscription and an unshared durable subscription may not have the same name and client identifier. |
| If a shared durable subscription already exists with the same name and client identifier then a <code>JMSException</code> |
| is thrown. |
| |
| <p> |
| If <code>noLocal</code> is set to true then any messages published to the topic using this session's connection, or any |
| other connection with the same client identifier, will not be added to the durable subscription. |
| |
| <p> |
| There is no restriction on durable subscriptions and shared non-durable subscriptions having the same name and |
| clientId. Such subscriptions would be completely separate. |
| |
| <p> |
| This method is identical to the corresponding <code>createDurableConsumer</code> method except that it returns a |
| <code>TopicSubscriber</code> rather than a <code>MessageConsumer</code> to represent the consumer.</div> |
