If you are using JRE or jView instead of JDK, see the
documentation for those products for instructions on setting the
CLASSPATH variable.
CLASSPATH is the location of the jConnect runtime classes and/or jar files, and the Java home library for JDK 1.2.x or later. This section describes what you need in your CLASSPATH depending on which versions of JDK and jConnect you are using.
On Windows NT, Windows 95, and older Windows systems,
make sure that file and directory names are no longer than eight
characters plus a three-character suffix (“8.3 format”),
or that you use abbreviated (“mangled”) names as
displayed in a DOS directory listing (for example, progra~1 instead
of program files).
To use jConnect 5.x with JDK versions 1.2 and later, set the CLASSPATH:
On UNIX or Linux:
$JDBC_HOME/classes/jconn2.jar
On Windows:
%JDBC_HOME%\classes\jconn2.jar
JDK versions 1.2 and later do not require you to set the location of the Java runtime classes in your CLASSPATH.
To run the samples or the TDS-tunnelling servlet, set the CLASSPATH environment variable:
On UNIX or Linux:
$JDBC_HOME/classes/jconn2.jar:$JDBC_HOME/classes
On Windows:
%JDBC_HOME%\classes\jconn2.jar;%JDBC_HOME%\classes
Sybase does not recommend running JDK 1.1.x with jConnect
5.x.
In addition, the CLASSPATH should include the location of any application classes you have defined.
As explained in the next section, if you use Netscape, some restrictions may apply to the way you set your CLASSPATH environment variable.
The Java VM security manager will not allow a version of jConnect installed in your local file system to create a connection to a server, even if the server is your local system. This can create a problem if you use Netscape to run an applet that uses jConnect.
When Netscape needs to load jConnect to create a connection to a server, it looks for a CLASSPATH defined in its environment to find the jConnect classes. If it finds a CLASSPATH that you have defined to point to your local jConnect installation, it loads jConnect directly from the local file system, rather than from the server, and tries to create a connection. This generates a security error and the connection fails.
Therefore, if you are using Netscape to run jConnect applets, do not set the CLASSPATH to the local jConnect directory.
