Setting up Environment Variables
Hi all,
I am trying to set up some variables in a shell script. The variables contain values of various paths needed to run a java module. The problem is the variables dont seem to be setting at all.

here is what i am trying to do :

JAR_HOME=/home/was5/bdcms/scheduledjobs/lib
export JAR_HOME

JAVA_HOME=/usr/java131/bin
export JAVA_HOME

SOURCE_HOME=/home/was5/bdcms/scheduledjobs/src
export SOURCE_HOME

CLASS_PATH=.:/home/was5/bdcms/scheduledjobs/src/classes12.jar
export CLASS_PATH

echo $CLASS_PATH



------------END of code -------------

This echo prints the value correctly. Where as if i do the same from unix prompt after executing the script, the variable is always empty. I have tried all kinds of things here(including export CLASS_PATH=value and export SET CLASS_PATH=value among others) and am not able to figure the problem.

Any help or pointers are appreciated.
Thanks

pam_xauth

pam_xauth(8)						   System Administrator's Manual					      pam_xauth(8)

NAME

       pam_xauth - forward xauth keys between users

SYNOPSIS

       session optional /lib/security/pam_xauth.so arguments

DESCRIPTION

       pam_xauth.so is designed to forward xauth keys (sometimes referred to as "cookies") between users.

       Without	pam_xauth,  when xauth is enabled and a user uses the su command to assume another user's priviledges, that user is no longer able
       to access the original user's X display because the new user does not have the key needed to access  the  display.   pam_xauth  solves  the
       problem by forwarding the key from the user running su (the source user) to the user whose identity the source user is assuming (the target
       user) when the session is created, and destroying the key when the session is torn down.

       This means, for example, that when you run su from an xterm sesssion, you will be able to run X programs without  explicitly  dealing  with
       the xauth command or ~/.Xauthority files.

       pam_xauth will only forward keys if xauth can list a key connected to the $DISPLAY environment variable.

       Primitive access control is provided by ~/.xauth/export in the invoking user's home directory and ~/.xauth/import in the target user's home
       directory.

       If a user has a ~/.xauth/import file, the user will only receive cookies from users listed in the file.	If  there  is  no  ~/.xauth/import
       file, the user will accept cookies from any other user.

       If  a  user has a .xauth/export file, the user will only forward cookies to users listed in the file.  If there is no ~/.xauth/export file,
       and the invoking user is not root, the user will forward cookies to any other user.  If there is no ~/.xauth/export file, and the  invoking
       user is root, the user will not forward cookies to other users.

       Both  the  import  and export files support wildcards (such as *).  Both the import and export files can be empty, signifying that no users
       are allowed.

ARGUMENTS

       debug  Turns on debugging messages sent to syslog.

       xauthpath=/usr/X11R6/bin/xauth
	      Specify the path the xauth program (the default is /usr/X11R6/bin/xauth).

IMPLEMENTATION DETAILS

       pam_xauth will work only if it is used from a setuid application in which the getuid() call returns the id of the user running the applica-
       tion,  and for which PAM can supply the name of the account that the user is attempting to assume.  The typical application of this type is
       su.  The application must call both pam_open_session() and pam_close_session() with the ruid set to the uid of the  calling  user  and  the
       euid set to root, and must have provided as the PAM_USER item the name of the target user.

       pam_xauth  calls  xauth as the source user to extract the key for $DISPLAY, then calls xauth as the target user to merge the key into the a
       temporary database and later remove the database.

       pam_xauth cannot be told not to remove the keys when the session is closed.
