Where's the Documentation?
The complete HTML documentation can be accessed from the file
index.html in your InterClient docs directory. On Windows, the
InterClient program group contains an icon for the InterClient
documentation.

What is InterClient?
InterClient is an all-Java JDBC driver for InterBase.
InterClient is a networked driver, meaning that it incorporates a
JDBC remote protocol for exchanging and caching data between
client and server. This allows for a browser enabled client with
no preinstalled client libraries (such as ODBC) to access
InterBase data across the net. This differs from a JDBC bridge
which maps from the JDBC API to some native RDBMS client API or
ODBC. A JDBC bridge implementation relies on the RDBMS client
library for the actual exchange and caching of data between
server and client.
The advantage of a networked driver over a bridge implementation
is that the client is 100% pure Java, thereby providing for
cross-platform, robust, and secure applets. Whereas a bridge
implementation requires some binary code to be pre-loaded on each
client machine, contrary to the notion of an applet.
The JDBC remote protocol employed by InterClient is streamlined
for JDBC data access, and is database independent except in cases
where InterBase access can be optimized or proprietary InterBase
features may be leveraged.

How Does InterClient Differ from DataGateway and Other Drivers
The DataGateway Broker was derived from InterClient. But
DataGateway's server speaks BDE on the backend or middle tier.
InterServer speaks ISC on the server backend or middle tier.
Also, since InterClient/InterServer is middleware intended only
for InterBase, it can be, and is, streamlined for InterBase.
Being an all Java type 3 driver provides much more flexibility than
a type 4 jdbc driver (which is pinned to a legacy protocol).
These things give rise to a driver which we believe to be the fastest
driver on the market today, often being orders of magnitude faster
than drivers such as jConnect and dbANYWHERE.
__________________________________________________________________
Compatibilities
Neither InterBase nor InterServer need to be installed on
the client machine, nor even InterClient if running applets.
InterClient 1.50 is compatible with the
Java Runtime Environment (JRE) 1.1
InterServer 1.50 and InterBase 5.x
InterServer 1.50 has been tested with
Windows 95/98 and NT 4.0
Solaris 2.5.x
HP-UX 10.x

How to Obtain InterClient Updates
Periodic revisions are made available on the InterBase web site
at http://www.interbase.com.
__________________________________________________________________
Configuration
On both Windows and Unix, the following
entry must appear in the services file.
interserver 3060/tcp
The TCP/IP services file was modified as a part of the
installation. You can add the above line manually if you
decided not to have setup make the modifications for you.
The services file can be located as follows:
* Windows NT <WINDOWS_DIR>\system32\drivers\etc\services
* Windows 95/98 <WINDOWS_DIR>\services
* Unix /etc/services or an NIS services map
For Unix only, an entry in the /etc/inetd.conf file is also required:
interserver stream tcp nowait root /usr/interclient/bin/interserver interserver
The CLASSPATH environment variable should be updated to include
<INSTALL_DIR>\interclient.jar
These configurations should be performed automatically by the
Windows install program. The class path configuration for
Unix must be performed manually.

Testing Your Configuration
See the Troubleshooting section of the InterClient Help html for
detailed instructions on testing your machine configuration for
running InterClient applications using
java interbase.interclient.utils.CommDiag
and for instructions on testing your applet configuration using
CommDiag.html
