running your "exec" script in the background is not sufficient?

Then you want a crontab to make sure 'exec' is running?
The screen is interactive and the only way to view the output.
The exec script covers keeping the Java server running only if it doesn't consume all available memory and the OS doesn't kill all of the processes.
The exec script is executed in the screen to run, view, and interact with the server with ./exec .
When the machine the server is on is rebooted, I would like a script to cd to the server dir, start a screen with screen -S server1, then execute the exec script within the screen with ./exec . Then have the script check to make sure all of the processes are running. If not, restart them.
Sorry for not being able to explain everything very precise or easily.

dmxchangescreensattributes
DMXChangeScreensAttributes(3) Library Functions Manual DMXChangeScreensAttributes(3)
NAME
DMXChangeScreensAttributes - change back-end screen attributes
SYNOPSIS
#include <X11/extensions/dmxext.h>
int DMXChangeScreensAttributes(Display *dpy,
int screen_count,
int *screens,
int mask_count,
unsigned int *masks,
DMXScreenAttributes *attr,
int *error_screen);
DESCRIPTION
DMXChangeScreensAttributes() changes the geometries and positions of the DMX screen and DMX root windows on the back-end X servers.
screen_count specifies the number of screens to be changed. For each screen, the screen number is placed in screens, an attribute mask is
placed in masks, and a DMXScreenAttributes structure is included in attr.
An explanation of the DMXScreenAttributes structure is given in DMXGetScreenAttributes(3).
The values that are used to compute each value in masks are as follows
DMXScreenWindowWidth
DMXScreenWindowHeight
DMXScreenWindowXoffset
DMXScreenWindowYoffset
DMXRootWindowWidth
DMXRootWindowHeight
DMXRootWindowXoffset
DMXRootWindowYoffset
DMXRootWindowXorigin
DMXRootWindowYorigin
In general, mask_count should be equal to screen_count. However, as a convenience, mask_count may be less than screen_count, and the last
entry in masks will then be used for all of the remaining screens. For example, this allows identical changes to be made to several
screens using only one mask.
RETURN VALUE
On success, 0 is returned. Otherwise, error_screen is set to the value of the first screen in the list that caused the error and a non-
zero value is returned. If screen_count or mask_count is less than 1, or if any of the attribute values are not within the appropriate
bounding boxes, DmxBadValue is returned. If a protocol error occurs, DmxBadReply is returned.
DMXChangeScreensAttributes() can generate BadLength (if the data provided does not match the data implicitly required by the screen_count
and mask_count values), BadValue (if the values in screens are not valid), and BadAlloc errors.
