ANN : JyRetic EAI Server 1.0RC3 released

Discussion in 'Python' started by Alexander DEJANOVSKI, Feb 27, 2004.

  1. JyRetic 1.0RC3 was just released.

    Changes are (I might have forgotten some bug fixes):

    - Bug fix : Scheduled events didn't work if no parameter file was required
    - Improvement : Speeded up SQL source when there were several records to
    extract (~x10)
    - Improvement : since JDBC drivers return rowcount on query execution,
    there's no need
    (as there was in Python) to execute a count(*) for each query (which was
    automatically done).
    This gives drastical speed improvements (and works for all types of query)
    - New : XindiceSource component. Perform XPath queries on Xindice
    Collections as data source.
    - New : DateMetadata preprocessor.
    - New : Jabber Postprocessor
    - New : SMTP Postprocessor
    - New : The adaptor class is now fully Java compatible and can thus be
    instantiated from a Java prog. (I'll bundle a Jar distribution to achieve
    this properly)
    - New : Adaptors execution tracking is now stored into a HSQLDB embedded
    server => faster and more reliable communications with server
    ===== Note =========
    - Improvement : SQLTree and SQLTreePlus sources have evolved in
    parent/child link strategy. Pre-existing adaptors won't work anymore.
    Please refer to the doc in order to know how to modify
    your adaptors.

    Retic Administrator 1.2 was released too !!

    Changes are :

    Note : Upgrade to JyRetic 1.0RC3 at least or expect problems in server/gui

    - Improvement : Use of hourglass cursor while performing communications
    with server
    - New feature : Added the "Copy periodicity" button on recurrent events
    - Improvement : Use of tabs in schedule and execution tracking to improve
    - Bug fix : Adaptors opened from server didn't display correctly
    (preprocessors, postprocessors)
    - Great new feature : Now the adaptor designer can open several adaptors at
    the same time, using tabs.
    - New : Added new informations about adaptors in execution tracking :
    Polls executed so far, Polls left, Messages treated so far, Messages left,
    Message treatment rate, Estimated poll end.
    - Improvement : GUI layout reworked a bit for better legibility (separated
    Adaptor/param lists and execution tracking)


    Retic is an EAI Server.
    The aim is to permit applications to communicate, even if they
    don't speak the same language (which means transport protocols
    as well as data structures).
    This is done by building adaptors. An adaptor is composed of :
    - One source
    - Several pipes (process data transformations)
    - Several sinks (destination of data)
    - Several loggers (using log4j)
    - Preprocessors (executed only once before adaptor execution - for
    example => drop/create a table through a SQL query)
    - Postprocessors (executed only once after adaptor execution - for
    example => creation of an index on a table through a SQL query)

    It is written in Jython and works 100% fine with only Java 1.3+ installed
    on your system (jython 2.1 is embedded in the releases).
    It provides connectivity with : JMS, HTTP, SOAP, UDDI, FTP, Xindice, JDBC,
    Jabber, SMTP and more...


    Enjoy !!

    PS : I'd need some help to restart the Python version of Retic. Anyone
    interested in contributing should contact me.
