In Windows NT, your

CLASSPATH

is set through the

System icon in the Control Panel. If you do not know
how to change your environment variables, ask your
system administrator.

Examples of Good and Problematic

CLASSPATH

Settings

This minimal setting is required for Web
Management:

SET CLASSPATH=C:\3Com;

The following setting is also acceptable:

SET CLASSPATH=C:\3Com;C:\java\classes;

This setting can potentially cause problems:

SET

CLASSPATH=C:\java\classes;C:\myclasses;C:\3Com;

The next setting results in unspecified behavior,
because certain 3Com Web Management directories
are not included. An unspecified

CLASSPATH

has simi-

lar results. In either case, the installed Web Manage-
ment applications may fail to run:

SET CLASSPATH=C:Local Status Log
