Release Notes for 3.6.2

30004: Improve JAX-WS handler config on server-side

The JAX-WS demo showed an XML-based handler config mechanism that did not support init preferences for the handler. This has now been fixed by including a programmatic configuration mechanism.

30108: Update documentation to new handler config

The documentation now mentions the new handler configuration mechanism instead of the old one.

Release Notes for 3.6.1

29311: Demo for JAXWS

Added demo for JAXWS transactions; see examples/jaxws.

29313: Add documentation for web services

Added more documentation for web services.

29592: Remove obsolete module: transactions-jetty5

Removed some obsolete legacy modules (jars).

29596: Implement unexportEndpoints

Added unexport of the SOAP endpoints during shutdown.

29905: Include TransactionsEssentials 3.5.4

Upgraded to 3.5.4 of TransactionsEssentials.

30005: activeRecovery init parameter is obsolete for handlers

Its value is now inferred by the other handler settings.

30013: Change URI scheme to atomikos://

The URIs created for transaction IDs are now prefixed with atomikos://

Release Notes for 3.6

28661: Change URI format

The URIs for transactions are now of the form fake:// because they are not really accessible in a REST-style (via http).

29510: Add JAXWS support

We now support transactions that span multiple JAXWS (SOAP) services.

Release Notes for 3.5.1

27885: QueueConnectionFactoryBeanBeanInfo inconsistent: xidFactory

The xidFactory attribute had been removed from the bean class but not from the bean descriptor; this is now fixed.

28665: Shrinking pool: should check whether connection is being used or not

The connection pool would not always check if a connection was in use before destroying it. Under high loads this would lead to problems, and this bug has now been fixed.

28678: ConnectionPool borrowConnection: exception causes destroy of last pooled connection!

An error while checking for available connections would lead to the improper destroy of the last connection in the pool - this has now been fixed.

28623: jms connection pooling bug

Fixed a threading issue reported in the forums: http://fogbugz.atomikos.com/default.asp?community.6.506.0

28843: Connection in use after timeout in nonxa JDBC

In some cases (notably a transaction timeout in between borrowing and first using a connection) the connection state would get corrupted, leading to subsequent messages like: "Connection accessed by transaction ... is already in use in another transaction:... Non-XA connections are not compatible with nested transaction use." This has been fixed.

28388: Resource already registered using JMS

Fixed a bug in the JMS JNDI mechanism - for details see this forum post: http://fogbugz.atomikos.com/default.asp?community.6.460.1

28680: Refactor borrowConnection in pool

Improved the logic for borrowing a connection.

29060: NPE when checking pool connections under high load

Fixed a bug where race conditions could lead to NullPointerExceptions in checking a non-xa connection's reusability.

Release Notes for 3.5

26833: Refactor startup properties (moved out of TSInitInfo)

The startup properties are no longer in the API but are now in the implementation-specific UserTransactionServiceFactory classes.

23398: CommitServer: reuse core thread pooling?

Commits are now done with the more recent core thread pooling mechanism. This deprecates the init parameter 'com.atomikos.icatch.soap_request_threads'.

27524: Update javac in build.xml: add source="1.4"

We now again allow Java 1.4 to be used at runtime.

27857: Transaction timeout in JDBC results in autoCommit mode

Fixed a bug in the connection state handling: timeout and rollback could result in a JDBC connection with autoCommit on.

27885: QueueConnectionFactoryBeanBeanInfo inconsistent: xidFactory

The xidFactory attribute had been removed from the bean class but not from the bean descriptor; this is now fixed.

27920: Default timeout property wrong name

The property name in the sample jta.properties file was wrong - this has been corrected.

27793: Non-xa proxy: useCount incremented twice when reusing exisiting proxy

When the same thread called getConnection() twice then there was a reuse bug as reported here: http://fogbugz.atomikos.com/default.asp?community.6.411.0

27614: Deadlock in JMS during onTerminated callback of PooledJMSConnection

Fixed a deadlock case between the connection pool and the JMS pooled connection, due to a synchronized observer callback.

21459: Maven POM support

We now offer a maven POM structure as a separate download.

21576: XAResourceTransaction: improve heuristic message

Improved (clarified) heuristic log comments for XA branches.

21689: Improve recovery problem across XA drivers

Improved recovery when the JDBC/XA drivers are upgraded between shutdown and restart.

26426: Add option to unsubscribe on close of topic receiver

The MessageDrivenContainer now supports unsubscribe on close - meaning that closing the container will also unsubscribe for any durable subscriptions (if this option is set).

21574: JmxLogAdministrator: option to show only heuristics

The JmxLogAdministrator can now be configured to show only heuristic transactions (i.e., the real problem cases) instead of all active transactions.

23486: Move startup properties out of TSInitInfo and into AbstractUserTransactionServiceFactory

Refactored the TSInitInfo interface to move out implementation-specific startup properties. These are now in the factory class(es) for the UserTransactionService corresponding to the implementation.

23693: Optimize roots: don't log prepared state

We have optimized logging even more for root transactions: prepared states do not generate any logging overhead any more. This cuts down logging costs by 30% or more.

21350: Add support for destinationName in JMS utilities

The JMS utility classes (in package com.atomikos.jms.extra) now support setting the (provider-specific) destinationName; this facilitates Spring (or other) configuration because you no longer need to obtain a reference to a Destination object first...

26045: Make build work for Java 5

The build now works for Java 5 also. Previously, the build could only be done on JDK 1.4

26911: Improved handling of heuristic hazard problems

Heuristic (hazard) exception states are now managed even better - this includes improved retry handling and better resolution after recovery.

26976: Deadlocks

Fixed a deadlock in the JMS pools.

24071: Simplify nonxa with new connection recycling

Simplified the thread-specific reuse of non-xa JDBC connections, by exploiting the newer 'connection recycling' that is now built-in into the pools.

24109: Heuristic messages: improve clarity

Heuristic log comments were improved for extra clarity.

24579: Support commit ordering

If single-threaded two-phase commit is enabled (in the jta.properties
file) then commits are now executed in the same order as the resources were
accessed by the transaction.

26240: Create Hibernate ConnectionProvider

We have added a Hibernate ConnectionProvider implementation to facilitate Hibernate 3.3+ configuration of the DataSource.

26398: Allow resume of transaction with status MARKED_ROLLBACK

It is now possible to resume a transaction after it was marked as rollbackOnly.

25809: Refactor MessageDrivenContainer to allow hot property change detection

The MessageDrivenContainer now allows (re)setting most of its properties after initialization.

New as from release 3.2.2

Bug fixes:

22436: RMI export/import: properties are not included?

RMI export/import: fixed a bug where properties were not included - leading to an independent root transaction on the importing side.

22437: RMI demos: don't work if rebuilt?

Fixed build.xml for j2se demos so that rebuild doesn't make the RMI demos crash.

22440: RMI demo fails: non-xa datasource incompatible with sibling transactions

Upgrade Guidelines For Users of Transactions 2.x

Users of the RMI/IIOP functionality in the Transactions 2.x editions should take the following changes into account. Due to refactoring, this product will not work as a drop-in replacement for the 2.x series.

Configuration changes

The value of the startup property com.atomikos.icatch.rmi_export_classMUST be set in your startup properties, or RMI/IIOP transactions will not be available (this features was enabled before, but is now disabled by default to make the software easier to use in most of the practical scenarios). See the sample properties file included in the release for possible values of this property.

The properties file can now also be called 'transactions.properties' instead of just 'jta.properties'. Extra properties were added to support new features (see the sample properties file included in the release).

Moved from package com.atomikos.icatch into package com.atomikos.icatch.config:
