Pressing ENTER in Command Prompt to solve hanging
Hi,
Does anyone know why sometimes Java hangs, unless you press ENTER in the
Command Prompt for Windows 2K? After pressing ENTER it continues execution.
It happens with WebLogic sometimes too. It will not print anything on the
console until I press ENTER.
I'm sure lots of Java developers have experienced this weird problem.
Thanks,
Duke

That is what we call a "feature" of an enterprise-class OS ;-)

On windows machines be very careful to turn off the "mark" option in
the shell preferences. It can halt the server.

because you marked something in the command prompt. Marking stops
execution. Enter means 'copy' and continues execution...

Module pool screen field should default without pressing enter
Hi
I have got a main module pool screen which has a tabstrip with four tabs.
There are 2 fields in the main screen when we select from F4 for the first field then the field 2 should default in case of a condition.
This happens only when i press enter. I want the second field to change as soon as the first field is selected.
How do I trigger the PAI as soon as the field 1 is selected.
eg: Field 1 : i/p
Field 2 : display
Field 3 : i/p
On F4 for field 1 say i select value 'A' then the valu for field 3 should default to value 'B'. Also field 2 should be displayed based on combination of field 1 and field 2. But now it does it only on pressing enter.
How do I solve this problem?Also if i select field 1 value A and dont press enter and go to the subscreen tab then it does not do any thing. It allows to go on the subscreen tab. But actually it should default the field 3 value. It does it only when I press enter.
Also the F4 is from dictionary that is the screen fields are from dictionary. I have not created any F4 for the fields.
Please help me solve this problem
Regards,
mozilaHi
You can achieve this using List Box only not by Input Field. Since Input field doesn't trigger automatic PAI/PBO
Go through the below thread
populate drop down menu based on entry in another field
or an alternative is--> In PBO use POPUP_GET_VALUES Fm to get the First input field based on that you can enter further values

Create theme path using Command prompt & telnet?
Hey guys I want my SMP to display linksheets. I have the latest firmware installed. I have been successfully running GBBM off of a usb (using the latest wdlxtv firmware) & my linksheets display fine. However, some films stutter & pause when using wdlxtv (they play fine when I unplug the usb stick & run the official firmware). So my aim is to change the theme path so that GBBM is booted from my usb stick & I can display linksheets but I will be using the official firmware. I have been following this guide found on the forum: http://community.wd.com/t5/WD-TV-Live-Streaming/Getting-around-the-30MB-theme-limit-and-repointing-the-SMP-to/td-p/631463 After attempting to set the theme path I reboot my SMP but it is still at the default theme.
When I look under 'appearance', it states my theme path that I entered in Command Prompt.
I think that I may be entering the theme path slightly wrong.
My USb is identified as: /tmp/media/usb/USB210/4489-F8EA
The folder that I created on my USB was: wdtv_themes
So I assumed my theme path would be: config_tool -c THEME_PATH=/tmp/media/usb/USB210/4489-F8EA.wdtv_themes
However, this doesn't seem to work.
Any help?this is all over my head, but KAD79 is about the only person that could help you with this but i did notice one thing, the path is missing a missing forward slash ? bird06 wrote:

Nokia 5610 new phone hang when press enter key; it...

I sent it to reinstalled the software and it looks ok now but, anyone know for new phone, how long the battery will last? My unit found only two days without playing music all the time.
Just an advise
On it's first time fully charge and discharge - vice versa for three times. After that don’t drain your battery every day to 10-20% of its charge. You can actually expect battery problems by draining the battery frequently.
Roughly every 30 charges, deliberately discharge your battery to 10-15%, and fully charge to 100% afterwards.
This will help maintain the accuracy of the “fuel gauge” on the device (your battery meter or scale). It has nothing to do with the battery memory but helps maintain the accuracy of the device’s percentage of battery charge left.
Good luck -
Running commands with powershell - randomly need to press Enter for the command to continue
Hi,
I have noticed quiet a few times now that when i run some commands in a powershell window, the execution seems to hang and if i press enter the rest of the command is executed.
It does it for such as simple thing as
xcopy \\source \\dest
repadmin /syncall /Adep
The commands are executed but i need to press enter at some point (and multiple times) for the command to complete.
Anyone have seen this kind of behavior?Something very similar to this came up recently, so I'll throw it out there. Do you have "QuickEdit Mode" enabled for your PowerShell console? If so, when you click your mouse somewhere in the window, it starts to select text to be copied or
pasted, and your window title will change from (for example) "Windows PowerShell" to "Select Windows PowerShell". When you press enter, you copy whatever was highlighted to the clipboard, and the console goes back to normal. -
Test Execution hangs while executing a test from Command prompt option
I have done the following
1) Created a script Test driver
2) Added different scripts as Script->Properties->Assets to the driver script
3) Call each of this asset script from TestDriver using command getScript("<<ScrptName>>".run(1, true, true, true);
4) Now calling this TestDriver script from command prompt with command
e:\\OracleATS\\agent
runScript.bat E:\\INTEGRATION_SERVICES\\Identity_management\\Automation\\Scripts\\MasterScripts\\TestDriver
TestDriver.jwg
The script execution hangs at "Initializing VU 1 for Script TestDriver. After few mintues of seeing this message i get error "Execution Timed Out".
Do I need to keep openscript UI open for script execution from command line ?
Is there any way to increase this Execution Time out ? May be it is taking time to load the internal script assets. AS other scripts are running fine on the same machine from command prompt itself.
Complete error is as follows

Execution Timed Out.Hi e_raja_sekar,
You wrote:
public static void main(String args){should be
public static void main(String args[]){Granted, the below code was tested on Windows XP using J2SE SDK 1.4.1_02 (and not 1.2.2 like Sridhar is using), but when I compiled and executed this code:
public class BadMain {
public static void main(String args) {
System.out.println("Hello World");
}The output I got was:
Exception in thread "main" java.lang.NoSuchMethodError: mainSo I don't think this is Sridhar's problem (but I could be wrong) since he says that he gets no error message.

I am having mac book air 2012model i had installed mavericks and use it, i long press command and power button at a same time and i saw the command prompt, from that i had formated the total hard disk. how to i want to install the OS again ?
i tryed with download mavericks but finally its saying a error message like cant conect to istore like that its saying and every thing is clear like internet and other stuf i tryed with 3times no progress same error pls help.. i bought this lap for my bro with his apple id only we use it now he got a new mac book pro so he gave to me so i formated and use it i use my apple id is that problem come because of changing apple id ? pls eplainFirstly, what is the source of the 10.6.4 disc? Is it the original installation disc for your MacBook, or one 'borrowed' from another computer?
It isn't the retail version, because that's 10.6.3.
Assuming it's the correct disc (i.e. the one that shipped with your Mac), you need to boot from it again.
OK the language page.
From the installer screen, ignore the continue button, go to the menu bar and choose Disk Utility from the Utilities menu.
In DU, select your internal drive in the sidebar (the top item with the makers name and serial no.).
Run Repair Disk. If that comes up as disk OK, click the partition tab. Select the partiton from the drop-down above the graphic; 1 partiton is all you need.
Go to the options button and ensure that the partition scheme is GUID and the file system to Mac OS Extended (Journalled). Name the partiton (usually Macintosh HD), click Apply.
When the Macintosh HD volume appears below the drive name, quit DU and see if you can then install.
If the screen after the language screen doesn't show the menu bar, it may be necessary to use another Mac to do the job with the MB in Firewire Target Disc Mode. If it won't boot in TDM, or the MB doesn't have FireWire then it's getting very difficult. -
Wait for command prompt - Enter-PSSession
Enter-PSSession -ComputerName ServerName
Restart-Service DNS -PassThru
Exit-PSSession
I am trying to restart the DNS Server service on several remote machines using a foreach loop. The problem is the the script does not wait until the command prompt shows up after executing the "Enter-PSSession -ComputerName ServerName".
I have not been able to fine a way to tell the script to wait for the prompt before continuing the script. Thank you for any assistance that can be provided.You can use
Invoke-Command rather than entering a PS-Session.
Something like this may do what you need:
$servers = @("Server1.fqdn.example.com","Server2.fqdn.example.com","Server3.fqdn.example.com")
$scriptblock = "Restart-Service DNS"
foreach ($server in $servers) {
Invoke-Command -ScriptBlock $scriptblock -ComputerName $server
Replace the server names in $servers with your actual server names. This assumes of course you have PSRemoting enabled which you would need for the PSSessions.

I have problem with iTunes story (secure link to itunes store failed). I make In the "Command Prompt" screen, type in netsh winsock reset the itune story is solve but after i close itunes the problem is back
The results show that you have a proxy server set and this can often cause problems with iTunes.
The proxy setting can be accessed in Internet options>>Connections>>LAN Settings.
Try un-checking the proxy server check box.
It might also be a good idea to run a malware check if you didn't know you had the proxy server set.

Invoking a command link's action from a javascript, on pressing enter key
i have the foll java script function. on pressing enter within an input field i want a certain commandlink's action to be automatically performed:
function checkKeycode() {
alert("entered");
var keycode;
if (window.event) keycode = window.event.keyCode;
//else if (e) keycode = e.which;
if(keycode==13){
alert("keycode: " + keycode);
var x=document.getElementById("form10:link1");
alert("about to click");
x.click();
//document.forms[0].link1.click();
//if(validate('form1:_system_username,form1:_system_password','form1:_id0,form1:_id1','2'))
//alert("about to submit page");
//submitPage();
}This fn is being called from the input text as follows:
<h:inputText styleClass="inputText" id="text1" size="32" onkeypress="checkKeycode();"></h:inputText>And the code containing the command link who's action i want to be called is:
<h:commandLink styleClass="commandLink" id="link1"
action="#{pc_Test.doLink1Action1}">
<hx:graphicImageEx border="0" styleClass="graphicImageEx"
id="imageEx1" url="../../images/search.gif"></hx:graphicImageEx>
</h:commandLink>
The javascript is being entered as i get an alert saying that enter key was pressed. However it is not performing the action requried, saying that "null is null or not an object"
could sumone please help????Hi
From your javascript , it is known that this is only work in IE,
And indeed it works fine, mybe there is another button which the default in your jsp
Change your code like this:
onkeypress="return checkKeycode();"
and at end of your javascript return false when you call x.click

[SOLVED] Adding users with command prompt
I'm doing as the beginers guide says for adding non-sudo users to my installation. I'm using
adduser
to do this. For the bash bit is pressing enter to just have /bin/bash, which I assume is default ok? I also pressed enter to have default for user ID. The longer way around it had this as an example:
useradd -m -G users,audio,lp,optical,storage,video,wheel,power -s /bin/bash archie
I'm looking in particular at the /bin/bash archie bit at the end. Do I leave it or make sure it's got the name of the user at the end e.g. in my case
/bin/bash ben
? It's just when I tried to do that the first time It gave me some message about it not being there.

[Solved]SSH messed command prompt
Hello,
I try to describe what is my problem. [CURSOR] - is my cursor
I connect to SSH. OK
I type command. OK
I can correct beginning of command. OK
I execute command. OK
$ echo 11111111111111111111111111
$ echo 0000000000000000000000000
I go to history - first command shows OK
$ echo 0000000000000000000000000
second history command when I try correct beginning(click home button or left arrow), I simply can't, I can access only 11-th letter of command.
$ echo 11111[CURSOR]111111111111111111111
now I go back to first history command
$ echo 11111echo 000000000000000000000000[CURSOR]
command prompt stay messed, and command can be executed successfuly only if I dont touch it.
I can go to beggining, but only 11th character
$ echo 11111[CURSOR]echo 000000000000000000000000
I press once more arrow down to get "live" clear command prompt.
$ echo 11111[CURSOR]
prompt stay messed, I cant delete string, only ctrl+c helps.
I tried urxvt and xterm. Generally it will happen If I execute command which has more than 30 letters.
Thanks for help.

[SOLVED] Bash: Append file contents to command prompt
Hi,
is there a way to append the contents of a file to the command prompt? Say I have defined an alias and I want to change it on the fly. So I'd do
$ which <my_alias>
then mark it with the mouse, and paste it to the command line. What I would like to do instead, would be:
$which <my_alias> > some_temp_file
$vim some_temp_file #edit the command the way I want it
$ # somehow get the file contents into the prompt here
I did try to google it, but to no avail and I know, I could just create a script from some_temp_file but I want the content to appear at the command prompt instead. So is there a way?
regards,
mox

Why do you want to have the command in a prompt twice? "read -er COMMAND && eval "$COMMAND"" creates a prompt-like environment and then executes the input string. What the options do you can read in the bash-internal help, e.g.:
$ LC_ALL=C help read
-e use Readline to obtain the line in an interactive shell
-i text Use TEXT as the initial text for Readline
-p prompt output the string PROMPT without a trailing newline before
attempting to read
-r do not allow backslashes to escape any characters
Here is an example:
[progandy@pamobile ~]$ alias some_test='echo -e Hello WORLD"!"'
[progandy@pamobile ~]$ command_to_edit="some_test"
[progandy@pamobile ~]$ read -erp "Edit and execute: " -i "$(command -v $command_to_edit)" COMMAND
Edit and execute: echo -e Hello WORLD"\t!"
[progandy@pamobile ~]$ ####### in the line above you edit the command and bring it in the final form with all necessary paramters.
[progandy@pamobile ~]$ echo -E " *~* Now running: $COMMAND"
*~* Now running: echo -e Hello WORLD"\t!"
[progandy@pamobile ~]$ eval "$COMMAND"
Hello WORLD !
[progandy@pamobile ~]$

Running a GUI application without holding command prompt
Hi there ,
I have developed a GUI application using Swing. After compiling the same successfully , when I run the same , presently , I am running it like ,
c:\> java xxx
where c:\ is the general command prompt on a Windows machine where I can type in my commands like javac or java and xxx is the class file name . Now till I complete using my GUI application and exit from the same , the command prompt will also be there ( and probably displaying the output of my System.out.println ) . So , two sessions are running , one is just the command prompt and another is the actual GUI application.
How can I avoide this ? e.g. when I type command "notepad" and press enter , notepad is started and the command prompt returns after starting notepad i.e. the notepad and the command prompt are not related now , I can close the command intrepreter and still notepad is running . What should I do to create such a Java GUI application ? Please advice .If I understand you correctly this is something that happens in linux also. And I believe that you can solve this by creating to shortcut to this program.
And the shortcut or link to application will be the command line that you use to run the Java Application.
i.e.
java c:\javadir\subjavadir\application.class
And I believe that this will allow it to run without the command prompt. Just showing the GUI and no additional command prompt window. Freeing the command prompt is something that I don't know how to do in either OS.
I use the Link To Application method because I ultimately don't need to have multiple windows for one application. Even though it is nice to be able to kill the Application by destroying the command-prompt session (in case your app causes lock-ups during testing).
Post your results . . . I'm not even sure that I'm being clear at all with my explanation to your question.
