Problem in calling rsh command Please help......

hi,
I want to execute some commands on unix through java, for this i want to run my program simulataneously on differnt machines so that i get data to compare.
I think i have to invoke the rsh command with the machine name for it but it is giving error as follows:
java.io.IOException: rsh eric52: not found
at java.lang.UNIXProcess.forkAndExec(Native Method)
at java.lang.UNIXProcess.<init>(UNIXProcess.java:71)
at java.lang.Runtime.execInternal(Native Method)
at java.lang.Runtime.exec(Runtime.java:582)
at java.lang.Runtime.exec(Runtime.java:505)
at java.lang.Runtime.exec(Runtime.java:471)
at RunCommand.get(RunCommand.java:18)
at RunCommand.main(RunCommand.java:80)
what should i do?
How do i run a command on a remote machine?
Please help me

Well you could always get your programs to talk to each other via RMI (for example)
Otherwise I would script this using ant and use ssh since rsh is insecure.

Greetings,
Questions:
1. What version of the Mac OS are you running (Apple > About this Mac)?
2. What version of the iOS are you running (Settings > About)?
3. Do you use MobileMe/ iCloud or another server based sync solution like Google or Yahoo?
4. Do other changes to synced information like Address Book content sync successfully back and forth?
Based on your description it sounds like you have a 1 way sync issue. Events sync fine between the iOS devices and fine from the computer to the iOS devices but not from the iOS devices to the computer.
Try:
Backup your computer and iOS devices before doing anything else:
http://support.apple.com/kb/HT1427
http://support.apple.com/kb/ht1766
Ensure all the devices in use are fully up to date: Apple > Software Update / Settings > General > Software Update
Make separate backups of critical data:
Backup your computer Addressbook: http://docs.info.apple.com/article.html?path=AddressBook/4.0/en/ad961.html
Backup your computer iCal: http://support.apple.com/kb/HT2966
Reset syncing on your Mac: http://support.apple.com/kb/TS1627
Reply back if that does not resolve your issue.
Hope that helps.

PLEASE CAN U GIVE ME EXACT CODE FOR CHANGES TO BE MADE IN THIS BADI ..AS IT IS NOT WORKING...
Can anybody help me regarding how to debug the BADI in R3.
Thanks in Advance...

Hi Ravi,
You can transfer the standard SRM catalog ID field to R/3 tracking number field (if not already used for another purpose) in the R/3 PO.
This will avoid to implement the R/3 inbound bapi.
Here is an extract of the code.
The ECS PO badi example was here used to transfer the unlimited delivery flag to R/3 PO for a Z combination of criteria as well as the transfer of <b>catalog ID</b> to <b>tracking number field</b> in R/3 PO :
method IF_EX_BBP_ECS_PO_OUT_BADI~BBP_B46B_PO_OUTBOUND.
update unlimited delivery flag in R3 PO for combination of vendor +
Product Category maintained in the bespoke table ZUD_PC_VNDR ..
LOOP AT ct_bapi_poitem INTO ls_bapi_poitem.
    lv_tabix = sy-tabix.
    IF ls_bapi_poitem-po_item IS NOT INITIAL.
      READ TABLE it_item INTO ls_item
           WITH KEY number_int = ls_bapi_poitem-po_item
                      del_ind    = ' '.
      IF sy-subrc = 0.
Set Unlimited delivery Flag
        read table li_zud_pc_vndr into ls_zud_pc_vndr
                        with key partner       = ls_partner-PARTNER_ID
                                   category_id = ls_item-category_id.
        if sy-subrc eq 0.
          ls_bapi_poitem-UNLIMITED_DLV = 'X'.
        endif.
Set the Dummy catalog.. entry..
        if ls_item-catalogid eq c_dummy.
          ls_bapi_poitem-TRACKINGNO = c_noncat.
        endif.
        ls_bapi_poitem-GR_BASEDIV = ' '.
        modify ct_bapi_poitem from ls_bapi_poitem index lv_tabix
                      transporting UNLIMITED_DLV TRACKINGNO GR_BASEDIV.
      ENDIF. "READ TABLE it_item ..
    ENDIF.   "IF ls_bapi_poitem-po_item ..
ENDLOOP.   "LOOP AT ct_bapi_poitem ..

I was able to use the findmyiphone app last week, but now I have been getting an error message "Can't load findmyiphone. There was a problem loading the application." please help as we are trying to locate an ipod with pics of a no deceased loved one.

Had the same problem and the same message -- was suddenly unable to access icloud apps on my pc, also using Windows 7 and Internet Explorer. After several days of pulling my hair out, decided to try a different browser and was able to get in by using Firefox instead of Internet Explorer. Hope this helps.

Problem with simple drawing program - please help!

Hi,
I've only just started using Java and would appreciate some help with a drawing tool application I'm currently trying to write.
The problem is that when the user clicks on a button at the bottom of the frame, they are then supposed to be able to produce a square or circle by simply clicking on the canvas.
Unfortunately, this is not currently happening.
Please help!
The code for both classes is as follows:
1. DrawToolFrame Class:
import java.awt.*;
import java.awt.event.*;
public class DrawToolFrame extends Frame
implements WindowListener
DrawToolCanvas myCanvas;
public DrawToolFrame()
setTitle("Draw Tool Frame");
addWindowListener(this);
Button square, circle;
Panel myPanel = new Panel();
square = new Button("square"); square.setActionCommand("square");
circle = new Button("circle"); circle.setActionCommand("circle");
myPanel.add(square); myPanel.add(circle);
add("South", myPanel);
DrawToolCanvas myCanvas = new DrawToolCanvas();
add("Center", myCanvas);
square.addMouseListener(myCanvas);
circle.addMouseListener(myCanvas);
public void windowClosing(WindowEvent event) { System.exit(0); }
public void windowOpened(WindowEvent event) {}
public void windowIconified(WindowEvent event) {}
public void windowDeiconified(WindowEvent event) {}
public void windowClosed(WindowEvent event) {}
public void windowActivated(WindowEvent event) {}
public void windowDeactivated(WindowEvent event) {}
2. DrawToolCanvas Class:
import java.awt.*;
import java.awt.event.*;
public class DrawToolCanvas
extends Canvas
implements MouseListener, ActionListener {
String drawType="square";
Point lastClickPoint=null;
public void drawComponent(Graphics g) {
if (lastClickPoint==null) {
g.drawString("Click canvas first",20,20);
} else {
if (drawType.equals("square")) {
square(g);
else if (drawType.equals("circle")) {
circle(g);
public void actionPerformed(ActionEvent event) {
if (event.getActionCommand().equals("square"))
drawType="square";
else if (event.getActionCommand().equals("circle"))
drawType="circle";
repaint();
public void mouseReleased(MouseEvent e) {
lastClickPoint=e.getPoint();
public void square(Graphics g) {
g.setColor(Color.red);
g.fillRect(lastClickPoint.x, lastClickPoint.y, 40, 40);
g.setColor(Color.black);
public void circle(Graphics g) {
g.setColor(Color.blue);
g.fillOval(lastClickPoint.x, lastClickPoint.y, 40, 40);
g.setColor(Color.black);
public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void mouseClicked(MouseEvent e) {}
Any help would be appreciated!

Some of the problems:
1) nothing calls drawComponent(Graphics g)
2) Paint(Graphics g) has not been overriden
3) myCanvas is declared twice: once as an instance variable to DrawToolFrame, and once local its constructor. Harmless but distracting.

create user abc identified by abc!
ERROR at line 1:
ORA-00922: missing or invalid option

Problem with touch screen. Please help!!!

Ok I bought an iPad about a month ago now. At first it worked perfectly, runs apps smoothly, etc. But then something happened to the touch screen, it just randomly like pressed itself, it went into apps on its own and zoom in and out while on safari just randomly. For about 3 weeks this issue disappeared, but now it happens again but more constantly and for more time please help. I think this video will explain my issue more clearly. http://www.youtube.com/watch?v=e1qyvHV43yg Please I just don't want this issue anymore. Any help will be appreciated.

OK...so it seems that many iPad owners have the same issue with the screen "self registering touches". You'll see multiple posts on the forums from "self touching" to "self registering" to "freaking out".
Well, I also have this annoying problem.
Trust me when I say that cleaning the screen, resets, charging, deleting apps, static, and so on haven't anything to do with causing or resolving this issue.
Here is a little tip to show you what is actually going on. Download a free app that shows you "screen touches". Harbor Master is one that I've heard of that led me to this...but I prefer to use that pocket pond app...only because I can just sit back and watch without having to move boats around.
...When you notice the problem, open up the app. I've noticed on mine that it only self registers touches along the side. Exact location is (when holding iPad in landscape position, home button on left) along the top of the screen...from top middle to the top right corner.
I have called Apple...the tech was polite and tried to help. ...But the only suggestions were to reset (as i've already done) then if that didn't work I was to do a reload while sync'd. He stated that if none of that worked then to take it to the store...
Since I am in Florida for the month and the nearest Apple store is 6hrs away...I will wait until I go back home HI and visit a store that is close by.

description: DLL function call crashed: QTInstallcode. QuictimePostInstallProc
for that complication of a broken quicktime, the following treatment usually works.
download and install the Windows Installer Cleanup utility:
Description of the Windows Installer CleanUp Utility
use it to remove existing Quicktime installation registry entries. then use the QT component of the uninstall instructions given in the following document as a guide to a manual uninstall of the existing QT program files and folders:
Troubleshooting iTunes, iPod Software, and QuickTime installation on Windows
reboot the PC. then let's try another standalone QT 7.0.3 install. we'll take some additional precautions this time.
download and save the QT 7.0.3 installer to your hard drive. (we'll run the install from there rather than on-line.) switch off any antivirus and antispyware applications prior to the install.
reboot and try to launch itunes again.
keep us posted.

SQL*PLUS using START command - please help me to understand

Hello dear friends,
I met one issue that i can't understand. Could you please explain me what is wrong in my logic.
I have created sql file called DUMMY.sql
the file context is:
SELECT dummy
FROM dummy_tbl
WHERE dummy_col=&dummy_var;
I go to SQL*Plus DB version (10.2.0.4.0).
I promt command: START DUMMY 1
and expecting *&dummy_var* to be replaced with *1* and query be executed as it is described in Oracle SQL*PLUS reference ([http://download-west.oracle.com/docs/cd/B12037_01/server.101/b12170/ch6.htm#sthref1058|http://download-west.oracle.com/docs/cd/B12037_01/server.101/b12170/ch6.htm#sthref1058] ).
But instead i'm getting Enter value for dummy_var:
please help me to understand
thanks in advance.

You need to use &1 instead of &dummy_var.
The number references the position of the parameter to use;&1 is the first parameter, &2 would be a second parameter and so on.
SELECT dummy
FROM dummy_tbl
WHERE dummy_col=&1;
