ANNOUNCE xmlBlaster release 0.78

[Marcel Ruff <ruff at swand.lake.de>]

Buon giorno,

release 0.78 is out.



Changes for 0.78 [Jul, 14 2000]
==============================
  - Added generic database access from James to xmlBlaster core.
    The JDBC gateway uses now the native interface to xmlBlaster.
    Added advanced JDBC connection pooling. Every user has
    its own pool, allowing heavy load server simultaneous
    database access (thread save).
    See online requirements for more informations/examples:
      
http://www.xmlBlaster.org/xmlBlaster/doc/requirements/engine.service.rdbms.html
      
http://www.xmlBlaster.org/xmlBlaster/doc/requirements/engine.service.rdbms.jdbcpool.html

  - Michele Laghi added complete C++ client support for MICO and
ORBacus.
    He implemented all necessary C++ client helper classes for easy and
cool
    xmlBlaster access.

  - Moved xmlBlaster/src/idl/xmlBlaster.idl to directory
    xmlBlaster/src/java/org/xmlBlaster/protocol/corba/xmlBlaster.idl

  - Changed package names:
    org.xmlBlaster.engine.persistence.I_PersistenceDriver ->
org.xmlBlaster.engine.I_PersistenceDriver
    org.xmlBlaster.engine.persistence.FileDriver          ->
org.xmlBlaster.engine.FileDriver
    org.xmlBlaster.util.MessageUnit                       ->
org.xmlBlaster.engine.helper.MessageUnit
    org.xmlBlaster.util.Destination                       ->
org.xmlBlaster.engine.helper.Destination
    org.xmlBlaster.util.CallbackAddress                   ->
org.xmlBlaster.engine.helper.CallbackAddress
    NOTE: You need to replace your xmlBlaster.properties
    with the new xmlBlaster.properties.template!

  - Changed classes:
    MessageUnit now contains the qos
    MessageUnitContainer is removed.
    Note that there is a CORBA MessageUnit and a
engine.helper.MessageUnit
    class (same name, same members).

  - xmlBlaster.properties allows variables ${...} replacement.
    see util.property.args.xml, util.property.env.xml, util.property.xml
    NOTE: You need to replace your xmlBlaster.properties
    with the new xmlBlaster.properties.template!

  - The "+" for command line options (e.g. +trace) is not supported
    any more, use for example '-trace true' instead.

  - There is now RMI support for xmlBlaster available.
    The Servers are in
       xmlBlaster/src/java/org/xmlBlaster/protocol/rmi
    A simple demo client is in
       xmlBlaster/demo/javaclients/rmi
    Read the INSTALL file about how to use RMI support.
    This is an alpha release, no test suite etc. yet.
    The reason for RMI support is a future support
    of JINI (which is based on RMI).
    The Discovery and Lookup of Jini are very fault tolerant
    and could be a base for xmlBlaster replication,
    load balancing and master/slave operation.

  - Added XmlBlasterException.java in org.xmlBlaster.util package.
    This allows Corba independend Exception handling.
    The xmlBlaster.idl defined XmlBlasterException
    is not removed and still resides in package
       org.xmlBlaster.protocol.corba.serverIdl
    NOTE: You need to change the package of XmlBlasterException
    in your code as well (if not thrown from Corba).

  - Added new package org.jutils to the xmlBlaster distribution.
    This replaces org.xmlBlaster.util over the time.
    You need to set the environment variable JUTILS_HOME to:
      export JUTILS_HOME=${XMLBLASTER_HOME}
    Changed package names:
       org.xmlBlaster.util.Log          -> org.jutils.log.Log
       org.xmlBlaster.util.FileUtil     -> org.jutils.io.FileUtil
       org.xmlBlaster.util.Queue        -> org.jutils.collection.Queue
       org.xmlBlaster.util.Args         -> org.jutils.init.Args
       org.xmlBlaster.util.Property     -> org.jutils.init.Property
       org.xmlBlaster.util.Memory       -> org.jutils.runtime.Memory
       org.xmlBlaster.util.StringHelper -> org.jutils.text.StringHelper
       org.xmlBlaster.util.StopWatch    -> org.jutils.time.StopWatch
       org.xmlBlaster.util.Timeout      -> org.jutils.time.Timeout
    rm Args.java FileUtil.java LogListener.java Log.java Memory.java
Property.java Queue.java StopWatch.java StringHelper.java

  - Compiled successfully xmlBlaster with JDK 1.3 for Linux.
    Performance enhancment for CORBA access ~ 80%

  - Compiled successfully xmlBlaster with TowerJ native compiler.
    Performance enhancment for CORBA access ~ 30%
    See .bashrc for used settings

  - Added protocol plugin possibility in xmlBlaster.properties
    Default settings are Corba drivers, example for RMI is provided as
well:
     
#------------------------------------------------------------------------------
      # List of all xmlBlaster access protocol drivers (I_Driver and
I_Callback implementations)
      # <protocol-type>:<driverClass>,<protocl-type>:<driverClass>,...
      # For protocol types see I_Driver.java
      Protocol.Drivers=IOR:org.xmlBlaster.protocol.corba.CorbaDriver
     
Protocol.CallbackDrivers=IOR:org.xmlBlaster.protocol.corba.CallbackCorbaDriver

  - Added native interface for xmlBlaster: I_XmlBlaster.
    All plugged in protocol drivers need to use this interface.
    The authentication is checked there in a controlled way.

  - The package org.xmlBlaster.authenticate is now CORBA independend.
    It uses or generates a unique sessionId string to track a login
session
    of a user. This allows easier integration of other
    protocols like xml-rpc.

  - Bug fix in PoolManager.erase() method

  - ClientConnection: removed deprecated logout(server)
                      Added killPing() in logout()




enjoy,

Marcel
