Interactively the user can select views, sort data, drill down through distribution or
other levels and display list and graphic output. The Java applet takes control of the
user actions. Users are having interactive access to SAS data without having
SAS TM software installed on the client pc.
The client can be a so-called thin client (e.g. a Net Computer), but must have
network access to the Web server . A Java enabled Web browser (e.g. Netscape
Navigator 3.0 or higher or MS Internet Explorer 3.02 or higher) must be installed. No
hard disk space is required but a minimum of 32 MB RAM.
On the Web server the Java tools must be installed. Using JTunnel a directory for
CGI-programs (e.g. \cgi-bin\) must have been setup.
The SAS TM release 6.12 or higher must be installed on the SAS TM server, including
SAS/ IntrNet TM software, SAS/Share TM and SAS/Connect TM software.
TM
dib-eisa/WWW is using Java tools being components of SAS/IntrNet TM Software:
Two drivers (set of Java class libraries that communicate with a SAS TM server) are
used to write Java programs:
ä JDBC (a „reduced“ ODBC-driver) is written in Java and gives users interactive
access to view and update data without having SAS TM software installed on the
client machine.
ä JConnect that enables to write Java programs to let you use the computing and
processing power of SAS TM software. It delivers SAS TM server functionality to
Java applets and applications.
ä Depending on the environment JTunnel is needed additionally when the SAS TM
server and the Web server are placed on different machines. JTunnel provides
access to network-wide resources. It is eliminating the restrictions on where your
SAS software runs in relation to your Web server and firewall.
