Hello all,

A new release of JASMQ, v01.10, is now available. The new release takes into account a number of remarks that I have received, as well as some personal suggestions. Do not hesitate to send me (or post on this site) further suggestions about JASMQ.

Download the new release from this site (current version is 01.00 but will soon be updated by Brandon):

What is JASMQ?

JASMQ is an easy-to-use message-driven application framework, used to process messages retrieved or browsed from a queue. JASMQ runs with J2SE (Standard Edition), with minimum configuration, and does not require experience of Enterprise Java development.

JASMQ saves a significant amount of repetitive development time, saves testing time, is tuned for high performance processing, and brings consistency and predictability to your enterprise applications.

What is new in JASMQ 01.10?

Registration:

* There is no more restriction on the unregistered version of JASMQ 01.10.

Platform support:

* In addition to Windows NT/2000, JASMQ has been successfully tested on AIX (v4.3.3 and v5.1) and SunOS (v5.7).

New features:

* In addition to consumer mode (destructive get), JASMQ can now process messages in browse mode, with the same ease of implementation. All you need to do is call setBrowse(true) or setBrowse(false). For compatibility with the previous release, the default mode is the consumer mode.

* Two new classes ApplicationServerController and ApplicationServerStatistics simplify the sending of command messages (trace on, trace off, stop) and collecting statistics from an application server.

* Statistic messages are now enriched with the application server configuration parameters (queue manager name, application queue name, application dead-letter queue name, browse mode, wait interval, repeat wait interval, maximum retry message, maximum consecutive reject message, syncpoint frequency, trace flag).

* The class ApplicationServer contains a new method setRepeatWaitInterval() to repeat consecutive wait intervals instead of stopping the application server after one single wait interval. The default value is 1, by compatibility with the previous release of JASMQ. The IApplication interface contains a new onWait() method. The application server calls onWait() between two consecutive wait intervals. The AApplication abstract class contains an empty implementation of the new onWait() method.

New samples:

* "MoveQueue" is a utility to move messages from one queue to another (discarding source messages).

* "CopyQueue" is a utility to copy messages from one queue to another (preserving source messages).

* The "JASMQ controller" swing application is a simple interface to send command messages to an application queue.

New documentation:

* The installation and configuration chapter contains distinct Windows and Unix sections.

New packaging:

* The package now contains a "scripts" directory to set the correct CLASSPATH, for both Windows and Unix platforms.

Changed features:

* The ApplicationServer class now closes the queues and disconnects from the queue manager when an exception is thrown (i.e. the Java code contains a finally clause).

* The ApplicationServer class now writes trace messages to standard error instead of standard output.

* The ApplicationServerException class has been renamed JASMQException.

Changed samples:

* The "PrintQueue" sample now displays the queue contents in browse mode (i.e. without discarding messages from the queue), to illustrate the new browse feature.

* The "FFServer" and "RRServer" samples are adapted to illustrate the usage of the onWait() method.

* The "CommandTraceOn", "CommandTraceOff" and "CommandGetStatistics" samples are adapted to illustrate the usage of the class ApplicationServerController.

* All the samples are adapted to write usage and banner to standard error instead of standard output.

* All the samples are adapted to call printStackTrace() on exception.

Changed documentation:

* Documentation correction, clarification, simplification and partial rewrite.
