Hi Peter,
Can someone please how I can execute an operating
system command or another program from Java. Example I
want to execute the Unix command ls from Java.I think you could use the following code:
try{
Runtime.getRuntime().exec("ls");
}catch(IOException ioe){
// some exception handler...
}Hope that helps

How to execute dos command in Java program?

In Perl, it has System(command) to call dos command.
Does java have this thing?
or any other way to execute dos command in java program?
Because i must call javacto compile a file when the user inputed a java file name.

Look in the Runtime class, it is implemented using the Singleton design pattern so you have to use the static method getRuntime to get its only instance, on that instance you can invoke methods like
exec(String command) that will execute that command in a dos shell.

How to execute system command from java program

Hi all,
I want to change directory path and then execute bash and other unix commands from a java program. When I execute them separately, it's working. Even in different try-catch block it's working but when I try to incorporate both of them in same try-catch block, I am not able to execute the commands. The change directory command works but it won't show me the effects of the bash and other commands.
Suggestions??

The code I am using is....
try
String str="cd D:\\Test";
Process p=Runtime.getRuntime().exec("cmd /c cd
"+str);your str string is already having cd in it but again you ar giving cd as part of this command also please check this,i will suggest you to remove cd from str
Process p1=Runtime.getRuntime().exec("cmd /c mkdir
"+str+"\\test_folder");you should say mkdir once you change your path,but here you are saying mkdir first and then cd D:\Test(this is because of str)..please check this
Process p2=Runtime.getRuntime().exec("cmd /c bash");
Process p3=Runtime.getRuntime().exec("cmd /c echo
himanshu>name.txt");
catch(IOException e)
System.err.println("Error on exec() method");
e.printStackTrace();

Execute Unix command from Java program running on windows

Hello,
I need to write a java program that fetches file count in a particular unix machine directory. But java program will be running on windows machine.
The program should execute unix list command and fetch the output of that command.
Can anyone help me on this?
Thanks.

Hi there,
I had a similiar problem, though years ago. It was to have a java program execute any other. Lately, I've had to have a java program running on a unix machine execute a shell script. Entirely two different scenarios. I'm not sure what you will need for your app, but look into this:
Java Native Interface for executing C/C++ code.
C/C++ Code for launching the program you need to run.
java.lang.Runtime(?).exec(....)
With a combination of that stuff, you can make a launcher for any os that has Java running on it, and with Runtime, you can exec() pretty near any sort of unix shell or app command you'd like.
Good luck.

Executing system command (third party program) from extend script without showing console on windows

I am using following code on mac:
app.system("/path/to/external/executable &");
It runs external program in background (without showing console/terminal).
On windows I tried many things like:
app.system('start "" "/path/to/external/executable"');
app.system('start "" /B "/path/to/external/executable"');
And I was also trying to solve it using visual basic.
Unfortunately everytime I use app.system(...) then windows console is showed on the screen for half of the second, then it disappears and progrm runs in background. Is it possible to avoid showing console window? Maybe there is another way of executing third party program?

You can try to save a vbscript :
Dim objShell
Set objShell = WScript.CreateObject( "WScript.Shell" )
objShell.Run("""\path\to\external\executable"""), 0, True
Set objShell = Nothing
than just execute it from javascript:
var vbFile = new File("path to your vbscript file")
vb.execute();

Executing external command and program in background

Hi,
how to execute external command and external program in background.
please provide me some tips on the same.
while creating external command, what is the significance of "operating system command" and "parameters for operating system command".
Thanks,
Dinesh.

Hi,
You can define external commands using transaction code SM69.
External commands are commands which would be executed at your operating
system with or without parameters.
Operating system commands are those which you execute at OS level like
mkdir, cat, rm, cp, ls
Parameters are options that you add to os commands to get more functionalities.
like, < ls -l > : will give you a long listing of files where " l " is the parameter
< ls -lt > : will give you a long listing with last changed file at top where " lt " is the parameter.
You can mention these in SM69 when you define the external commands.
Now, in order to execute these in your background job. In the steps click on "external command" and give your command name in SM36 while creating your job.
" Points for solution ".
Thanks and Regards,
Sandeep.

i have modified the code again.but still no result.....

Why am I being told that a JPEG file that I made changes to in Photoshop 6 (CS6) can't be saved? The message I get says that either the file is locked and I don't have permission to execute this or another program is using this file.

i recently purchased a 21.5 iMac with Yosemite (10.10.1) and was disappointed to discover that my CS6 programs are not functioning correctly. I am unable to use the "Save As" command when making changes to a JPEG file in Photoshop. The message I get says that either another program is using the file or it is locked and I don't have permission to execute that command. I'm experiencing a similar problem in Bridge when trying to move an unwanted file to the Trash. Again, I get a message telling me that i don't have permission to do this. Lastly, I'm unable to open any Camera Raw files. Any suggestions? I had no problems with the Mavericks OS on my old iMac and although it's much slower, I'm tempted to go back to using my old iMac. At this point, I feel as if I've just wasted $2300+ (tax included).

Back up all data before proceeding.
This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Triple-click anywhere in the following line on this page to select it:
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
resetp
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Executing another program with Java?

I'm relatively new to Java. I'd like to build a process-monitoring program that will allow me to determine the status of certain processes on the machine. In order to do this I need to know if Java can execute (and then of course read the output of) another program, in this case, the Unix 'ps' command.
Thanks.
David

yeah: look at the java.lang.Runtime and java.lang.Process APIs, specifically Runtime.exec . There are a ton of discussions about those APIs in this forum, so you can probably find some code examples as well, if you do a search... Take care.

Executing a report program in background from another program

Hi Experts,
I developed a report to display material change history based on change date range. Report is taking much time (around 15-20 mins) as I'm hitting CDPOS and CDHDR tables. User wants to execute the report in foreground because he/she can give selection criteria that is required everytime.
So, my requirment is now to create another program with same selection screen elements which will execute the original program in background. In the new program, we will be just capturing the selection elements and will pass them to original program to run in background and display a message to user without wait for the background job to complete. Original program should send an email to an fixed email id with the report output as attachment (for example excel file).
Please suggest.
Thanks in Advance,
Siva Sankar

Regarding a Change Document Function Module ----- VERY VERY Urgent
When using function modules , I dont think you can directly get data based on material and plant . these function modules usualy works with object class and creation date .
Once you retrieve the data using the function modules you have to filter out the unncecessary data based on your selection screen conditions .

Could not save Preferences because the file is locked, you do not have necessary access permissions, or another program is using the file. Use the 'Get Info' command in the Finder to ensure the file is unlocked and you have permission to access the file.

Execute a command in an external program.

Hi all,
I have a little question. I want to execute a command (ctrl+F1) in an external program. This program is already open, so i dont need to execute it. Is there a way to get the focus in this program and automaticly execute my command? I have checked around and all i found was how to execute the program.
Thanks alot
Alex

I want to execute a command (ctrl+F1)Thats a key stroke, not a command.
in an external program.I always ask this, but what is an internal program?
Is there a way to get the focus in this program and automaticly execute my command?Kind of. java.awt.Robot provides methods to simulate mouse and keyboard events. If you know where the window is on the screen, you could focus it using the Robot (move the mouse over it and click) and then issue a key event.
Not too easy.

Execute Command fron Java Program

Hi All,
I am trying to execute a command from Java Application, but iam not getting any result. My problem is:-
1- Open a terminal.
2- execute command.
The same is working fine in windows , the step for windows are:-
1- execute cmd.exe
2- go to prompt
3- execute command.
How to do it for Solaris 10 ??? Any cmd.exe equivalent for solaris terminal???

This is done in the exact same way. You open a terminal (depending on your gui its called "console" or "this computer" (CDE), and "Gnome console" (iirc) in the Java desktop) and then you're home free. "javac", "java", etc. should all be in your search path.
If not look in /usr/java.
