Oracle classpath

Oracle Database Tips by Donald Burleson

The CLASSPATH specification is important for Oracle Java J2EE programs to find your defined classes.  Also see the LD_LIBRARY_PATH and LD_LIBRARY_PATH_64 path locations.

There are two environmental variables that will effect the operation of your JAVA programs such as java, javac and appletviewer, these are PATH and CLASSPATH.

On UNIX the CLASSPATH can be set in the ".profile" file for each user or through a global setup ".profile" (file name may differ depending on the shell you use under UNIX). On a Windows platform a simple addition to the autoexec.bat file in the boot directory is all that is required to specify the CLASSPATH.

It can be difficult to get the various browsers to recognize new CLASSPATH variables, so getting some expert help to add this data to your browser path is suggested.

* CLASSPATH - Used to provide the system a path to user-defined classes. Directories are separated by semi-colons, for example,


* PATH - Used to tell the operating system what path to traverse to search for executables
