Spring's `JtaTransactionManager` is the standard choice to run on Jakarta EE application
servers and is known to work on all common servers. Advanced functionality, such as
transaction suspension, works on many servers as well (including GlassFish, JBoss and
Geronimo) without any special configuration required. However, for fully supported
transaction suspension and further advanced integration, Spring includes special adapters
for WebLogic Server and WebSphere. These adapters are discussed in the following
sections.
For standard scenarios, including WebLogic Server and WebSphere, consider using the
convenient `<tx:jta-transaction-manager/>` configuration element. When configured,
this element automatically detects the underlying server and chooses the best
transaction manager available for the platform. This means that you need not explicitly
configure server-specific adapter classes (as discussed in the following sections).
Rather, they are chosen automatically, with the standard
`JtaTransactionManager` as the default fallback.
[[transaction-application-server-integration-websphere]]
== IBM WebSphere
On WebSphere 6.1.0.9 and above, the recommended Spring JTA transaction manager to use is
`WebSphereUowTransactionManager`. This special adapter uses IBM's `UOWManager` API,
which is available in WebSphere Application Server 6.1.0.9 and later. With this adapter,
Spring-driven transaction suspension (suspend and resume as initiated by
`PROPAGATION_REQUIRES_NEW`) is officially supported by IBM.
[[transaction-application-server-integration-weblogic]]
== Oracle WebLogic Server
On WebLogic Server 9.0 or above, you would typically use the
`WebLogicJtaTransactionManager` instead of the stock `JtaTransactionManager` class. This
special WebLogic-specific subclass of the normal `JtaTransactionManager` supports the
full power of Spring's transaction definitions in a WebLogic-managed transaction
environment, beyond standard JTA semantics. Features include transaction names,
per-transaction isolation levels, and proper resuming of transactions in all cases.

Currently, you cannot have explicit control over the name of a transaction, where 'name'
means the transaction name that appears in a transaction monitor, if applicable
(for example, WebLogic's transaction monitor), and in logging output. For declarative
transactions, the transaction name is always the fully-qualified class name + `.`

For declarative transactions, the transaction name is always the fully-qualified class

`handlePayment(..)` method of the `BusinessService` class started a transaction, the
name of the transaction would be: `com.example.BusinessService.handlePayment`.

Such an independent inner transaction can also declare its own isolation level, timeout,
and read-only settings and not inherit an outer transaction's characteristics.
NOTE: The resources attached to the outer transaction will remain bound there while
the inner transaction acquires its own resources such as a new database connection.
This may lead to exhaustion of the connection pool and potentially to a deadlock if
several threads have an active outer transaction and wait to acquire a new connection
for their inner transaction, with the pool not being able to hand out any such inner
connection anymore. Do not use `PROPAGATION_REQUIRES_NEW` unless your connection pool
is appropriately sized, exceeding the number of concurrent threads by at least 1.
