This directory contains the Easysoft JDBC-ODBC Bridge.
The Easysoft JDBC-ODBC Bridge (JOB) provides zero installation JDBC access
from any Java platform to remote ODBC data sources on Unix, Linux and Windows
platforms. The main points to note about JOB are:
[1] You can connect to Microsoft SQL Server, Microsoft Access or any other
ODBC data source for which you have an ODBC driver. Access can be from Java
Applets, Applications, Servlets or Application Servers on any Java
platform.
[2] Unlike SUN's Bridge, JOB is Type 3, client server solution, allowing Java
applications and ODBC drivers to be on separate machines.
[3] JOB is J2EE compliant, as certified by SUN Microsystems.
[3] JOB supports core JDBC 2 methods in addition to all JDBC 1.22 methods.
[4] You can set and retrieve UNICODE data with ResultSet.getString() and
PreparedStatement.setString().
[5] On non-windows platforms JOB provides JDBC access to ODBC Data
Sources set up under the unixODBC ODBC Driver Manager.
[6] JOB ships with an simple, integral HTTP server to provide web based
remote monitoring and configuration of the JOB server.
The easysoft.sql.jobDriver package can be served by this web server
alongside applet code to achieve zero installation solutions.
[7] JOB provides outstanding performance when tested with JBench.
Demonstrations of Easysoft JDBC-ODBC Bridge in action are available at
http://www.easysoft.com/products/9999/demonstrations.phtml?product=2003
** You should only install this software onto a machine that has ODBC
** drivers that you want to access over the Easysoft JDBC-ODBC Bridge
** from other machines.
** If the ODBC data sources to which you would like to gain remote access
** from any Java platform reside on other platforms (such as Linux or Unix),
** please obtain and install the Easysoft JDBC-ODBC Bridge Server
** appropriate for those platforms.
** If you wish to gain access to your ODBC Data sources via JDBC from
** applets, you can use the built-in HTTP server to serve them.
** For production use it is recommended that you take the Easysoft JDBC-ODBC
** Bridge Driver classes from <install_path>/easysoft/job/EJOB.jar and make
** them available via your own Web server.
** If you are developing or deploying applications you can download
** the Easysoft JDBC-ODBC Bridge Driver classes directly from the machine
** that runs the server. See the page
** http://<your machine>:<EJOB HTTP PORT>/
On Unix and Linux systems you must be root to install the server properly
as it requires write access to /usr/local tree.
For information on installing the Easysoft JDBC-ODBC Bridge see the
INSTALL file.

09-Nov-2000
The registry entry [HKEY_LOCAL_MACHINE\SOFTWARE\Easysoft JDBC-ODBC Bridge\
Configuration\System\settings]"SingleStatement has been added. If it is
set to "y" or "Y" no attempt is made to overcome the backends restriction
to a single concurrent active statement. This is the default.
02-Nov-2000
The registry entry [HKEY_LOCAL_MACHINE\SOFTWARE\Easysoft JDBC-ODBC Bridge\
Configuration\System\settings]" Logging is set to 64 by default. It prints
statistics for each connection to stdout where the server is running.
Setting this flag to 0 disables this output.
Changes since 1.0.0.8
---------------------

Added patch to restrict connections to a specified DSN, the value of the
registry key HKEY_LOCAL_MACHINE\SOFTWARE\Easysoft JDBC-ODBC Bridge\
Configuration\System\Settings\DSN.
25-Oct-2000
JDBC URL in use is no longer printed out on stdout.

JDBC URL.
6-Oct-2000
JOB works well with JBuilder 3.5.

DatabaseMetaData.getTableTypes() generates a result set in which
getString(1) works. This is needed by JBuilder 3.5 and 4.
2-Oct-2000
Changed the default for the JOB Server configuration ReverseLookup
from on to off. Often customer networks do not have reverse lookups
working and it adds to the connection time. This change only affects
the statistics page where connecting clients IP addresses and names
are shown. With ReverseLookup off the machine names are shown as
"unknown".

Fixed bug in automatic switching from Smart Block Fetch Mode to getting
each column as a separate Remote Procedure Call (:fetchSize=0) and back.

DriverManager.setLogWriter() or with the :trace=on JDBC URL attribute
setting.

A single connection to the JOB server can be shared across several client
threads.
Changes since 1.0.0.7
---------------------
12-Jun-2000
Changes to the licensing now mean that the JOB Server
works out of the box for 1 connection without the installer applying
for a license key. The free 1 connection license is time limited
although no one is prevented from downloading a new time limited 1
free connection version at a later date.
12-Jun-2000

reused is now resolved.
15-Jun-2000
On server thread exit pending transactions are rolled back so that
inaccessible connections are not left open to the backend db.
09-Jun-2000

return the value of the first matching column name. (it used to be the last)
.
10-May-2000
Out of sequence, and repeated calls to ResultSet.getXXX calls now works
in Smart Block Fetch Mode (default) even if the underlying ODBC data source
does not support it.
Changes since 1.0.0.4
---------------------
5-May-2000
NULL status of columns was reported incorrectly.
4-May-2000
Second result set on a Statement object returned garbage in Smart Block
