Place a command in the command queue through code

Question

our bussiness needs require that the oracle lite server may send a command to the olite client. such a command may be an upgrade or install or exec file.
we have a problem placing commands in the command queue of the device so that the device may later pick them up and execute them.
if the client is not connected to the server through the specified protocol (rapi, http etc) then the command is not placed in the queue but it is marked as failed. this happens when we send commands through our code, but if we attempt to do it through the mobile manager then when the client is not connected the command is placed in the queue and when the handheld connects, it pulls the command.
my question is how should we alter the code below so that the command (install in this example) is placed in the queue when a fail to connect happens.
code in java:
private void jButton12MouseClicked(java.awt.event.MouseEvent evt) {                                      
ResourceManager rm = null;
String url="...";
String user="myuser";
Command Installcmd = null;
try {
ResourceManager.initialize(url);
rm = ResourceManager.getInstance();
User usr = rm.getUser(user);
this.Installcmd = dm.getCommand ("Install");
for (Enumeration e = usr.getDevices(); e.hasMoreElements();) {
Device dev = (Device)e.nextElement();
list4.add("Device");list4.add("------------");
list4.add("Device Name:"+dev.getName());
list4.add("Device Type:"+dev.getType());
list4.add("User Id:"+dev.getUserId());
if (dev.isEnabled()) {
DeviceCommand dc = new DeviceCommand (cmd, dev);
dc.send (DeviceCommand.HIGH_PRIORITY,null );
rm.commit();
} catch (Throwable e) {
e.printStackTrace();
JOptionPane.showMessageDialog(null, e.getMessage(),"Error",0);} finally {
try {if (rm != null) ResourceManager.destroy();
our problem lies on how we place the command in the command queue of the particular device. thank you for your time and efforts
