| <forwardingBridge> | Forwards all messages from the local broker to the remote broker. |
| <imageBasedJDBCAdaptor> | Provides JDBCAdapter since that uses IMAGE datatype to hold binary data. The databases/JDBC drivers that use this adapter are: |
| <inboundQueueBridge> | Create an Inbound Queue Bridge |
| <inboundTopicBridge> | Create an Inbound Topic Bridge |
| <individualDeadLetterStrategy> | A {@link DeadLetterStrategy} where each destination has its own individual DLQ using the subject naming hierarchy. |
| <informixJDBCAdapter> | JDBC Adapter for Informix database. Because Informix database restricts length of composite primary keys, length of container name field and subscription id field must be reduced to 150 characters. Therefore be sure not to use longer names for container name and subscription id than 150 characters. |
| <jaasAuthenticationPlugin> | Provides a JAAS based authentication plugin |
| <jdbcPersistenceAdapter> | A {@link PersistenceAdapter} implementation using JDBC for persistence storage. This persistence adapter will correctly remember prepared XA transactions, but it will not keep track of local transaction commits so that operations performed against the Message store are done as a single uow. |
| <jmsQueueConnector> | A Bridge to other JMS Queue providers |
| <jmsTopicConnector> | A Bridge to other JMS Topic providers |
| <journalPersistenceAdapter> | An implementation of {@link PersistenceAdapter} designed for use with a {@link Journal} and then check pointing asynchronously on a timeout with some other long term persistent storage. |
| <journaledJDBC> | Creates a default persistence model using the Journal and JDBC |
| <kahaPersistenceAdapter> | |
| <lastImageSubscriptionRecoveryPolicy> | This implementation of {@link SubscriptionRecoveryPolicy} will only keep the last message. |
| <loggingBrokerPlugin> | A simple Broker interceptor which allows you to enable/disable logging. |
| <managementContext> | A Flow provides different dispatch policies within the NMR |
| <memoryPersistenceAdapter> | |
| <multicastNetworkConnector> | A network connector which uses some kind of multicast-like transport that communicates with potentially many remote brokers over a single logical {@link Transport} instance such as when using multicast. This implementation does not depend on multicast at all; any other group based transport could be used. |
| <networkConnector> | A network connector which uses a discovery agent to detect the remote brokers available and setup a connection to each available remote broker |
| <noSubscriptionRecoveryPolicy> | This is the default Topic recovery policy which does not recover any messages. |
| <oldestMessageEvictionStrategy> | An eviction strategy which evicts the oldest message first (which is the default). |
| <oldestMessageWithLowestPriorityEvictionStrategy> | An eviction strategy which evicts the oldest message with the lowest priority first. |
| <oracleJDBCAdapter> | Implements all the default JDBC operations that are used by the JDBCPersistenceAdapter. Subclassing is encouraged to override the default implementation of methods to account for differences in JDBC Driver implementations. The JDBCAdapter inserts and extracts BLOB data using the getBytes()/setBytes() operations. The databases/JDBC drivers that use this adapter are: |
| <outboundQueueBridge> | Create an Outbound Queue Bridge |
| <outboundTopicBridge> | Create an Outbound Topic Bridge |
| <policyEntry> | Represents an entry in a {@link PolicyMap} for assigning policies to a specific destination or a hierarchical wildcard area of destinations. |
| <policyMap> | Represents a destination based configuration of policies so that individual destinations or wildcard hierarchies of destinations can be configured using different policies. |
| <prefetchRatePendingMessageLimitStrategy> | This PendingMessageLimitStrategy sets the maximum pending message limit value to be a multiplier of the prefetch limit of the subscription. |
| <proxyConnector> | |
| <queryBasedSubscriptionRecoveryPolicy> | This implementation of {@link SubscriptionRecoveryPolicy} will perform a user specific query mechanism to load any messages they may have missed. |
| <queue> | An ActiveMQ Queue Destination |
| <quickJournalPersistenceAdapter> | An implementation of {@link PersistenceAdapter} designed for use with a {@link Journal} and then check pointing asynchronously on a timeout with some other long term persistent storage. |
| <rapidPersistenceAdapter> | An implementation of {@link PersistenceAdapter} designed for use with a {@link Journal} and then check pointing asynchronously on a timeout with some other long term persistent storage. |
| <roundRobinDispatchPolicy> | Simple dispatch policy that sends a message to every subscription that matches the message. |
| <sharedDeadLetterStrategy> | A default implementation of {@link DeadLetterStrategy} which uses a constant destination. |
| <simpleAuthenticationPlugin> | Provides a simple authentication plugin configured with a map of user-passwords and a map of user-groups |
| <simpleAuthorizationMap> | An AuthorizationMap which is configured with individual DestinationMaps for each operation. |
| <simpleDispatchPolicy> | Simple dispatch policy that sends a message to every subscription that matches the message. |
| <simpleJmsMessageConvertor> | Converts Message from one JMS to another |
| <statements> | |
| <streamJDBCAdapter> | This JDBCAdapter inserts and extracts BLOB data using the setBinaryStream()/getBinaryStream() operations. The databases/JDBC drivers that use this adapter are: |
| <strictOrderDispatchPolicy> | Dispatch policy that causes every subscription to see messages in the same order. |
| <timedSubscriptionRecoveryPolicy> | This implementation of {@link SubscriptionRecoveryPolicy} will keep a timed buffer of messages around in memory and use that to recover new subscriptions. |
| <topic> | An ActiveMQ Topic Destination |
| <transportConnector> | |
| <usageManager> | Used to keep track of how much of something is being used so that a productive working set usage can be controlled. Main use case is manage memory usage. |
| <virtualDestinationInterceptor> | Implements Virtual Topics. |
| <virtualTopic> | Creates Virtual Topics using a prefix and postfix. The virtual destination creates a wildcard that is then used to look up all active queue subscriptions which match. |
