Java exec spawns command window

Hello,
I am using JRE 1.4.2 (Eclipse runtime environment). Whenever I execute the following command:
System.getRuntime().exec("<some command>");
I am getting a Command Window that pops up while the process executes and closes afterwords.
Is there any way to prevent this command window from appearing. I have chained all Error and Output streams within the java program but no luck. I guess the only other solution is to not make the exec calls by making native calls from the java program, but that would be a huge undertaking.
Thanks in advance.

Yes, I think you are correct.
When I do the same with say calc.exe or notepad.exe, I do not get this dos command prompt.
The command that I am trying to execute here is PCLI.exe (for PVCS). Do you have an idea of how I can deal with this program so that I do not get that annoying comand prompt?

DOS Commands Used in Java Pgm, but command window should NOT be visible!

Need a solution for the following.
Problem: In a Java program, DOS Commands are used.
Hence while executing it, the command window is visible for few seconds and later it is hided i.e once the processing of that DOS Command is finished.
Solution Required: The Command Window should not be visible. The DOS Commands should be performed in the background with out making the command window visible.

Problem:
I am trying to run a executable file through java . But a command window always pops up. I want the command window not to pop up while the code is executed. Alternatively the rt.exec method should run in the background till the process is complete.
I am using the following code in Java Swing application , where in when a user clicks a button the following method is invoked , which is turns invokes a windows a rasdial.exe file .Ex: rasdial MyConnection;
Can someone help me on this. The below is a snippet of my code .

Again...Suppressing the Java Command Window

Hi,
My invoking my java application with "javaw", I'm able to suppress the command window.
None of the System.out.println() is now seen. Thanks for that.
But there is another problem that I see.
In my application, I run some batchfiles using the Runtime.exec
with the "cmd" parameter. This is making a separate command window
pop up from no where.
This pop up is happening for every call I make ? Can this be avoided at all ???
Or should I live with it ??
Many Thanks

You may have to live with that cause cmd runs with its own window. I haven't used this very much but for the little I have done, I can't ever seem to get it to hide, unless you decide to use START to run the activity and then call EXIT in the batch file so it closes as soon as it is done.

Supressing the Java command window ???

Hi,
How do I get rid of the command window from where I start my Java Application ?
Even if there is a way what will happen to all the System.out.println() calls in my applicatio ?
Thanks in advance.

You can just not start the Java application from a command window or batch file. The easiest way to do this is to create an executable JAR file which a person (on Windows) can just double-click. Do a search on "executable JAR".

Minimizing the java command window?

I'm running a excutable jar file:
'java -jar myExe.jar'
i leave the command window open, and task manager window open next to it. when i minimize my command window, i see the CPU usage for the java process go down. why does it do that?

Nobody has experienced this before?

The trouble is although this script works great for commands that can be run is the 'background' as SYSTEM is I want to pass a command to actually open something e.g. notepad in the above example nothing seems to happen. As far as I can make out the command line is running but not as %username% so it's not running notepad.exe in the foreground.
I'm happy to clarify more if necessary.
Can anyone help with this?
Cheers

Bill,
Thank you for the quick answer. I believe you are right in your assumption.
I have been searching but found nothing so far.
I need to be able to run this line "wmic
Product where name='XXX XXX XXX' call uninstall"
in an elevated command prompt to uninstall the program.
I was looking for a VB script or PowerShell to execute it remotely on non domain roaming PCs.
Th3e command can be run remotely against stand-alone workstations but you must supply credentials. Post in the platform forum for you version of Windows for help in using the WMIC utility. WMIC /? will give you all of the command options fro
remote execution. UAC only affects local systems. You cannot use WMIC to remote back to the local system. WMIC does not allow impersonation to the local system.
Most installers will not automatically allow an unattended uninstall. If there is any dialog at all the uninstall will fail and can hang.
I recommend contacting the vendor of the application to get more information.
In all cases you cannot bypass UAC as Bill has noted. I am only noting that, sometimes, in a workgroup, you can use WMIC to remotely uninstall an application.
¯\_(ツ)_/¯

Ant task poping up command window

Is there any way to have ant stop poping up command windows for every 'java' execute task ?

You can work around it by invoking JDeveloper using jdev.exe instead of jdevw.exe. You'll still have a command window, but only one, and it will stay permanently.
This was a bug in java's Runtime.exec() functionality, and has been fixed in 1.4 (and consumed in JDeveloper 9.0.4).

Cannot run command window

In Windows I would expect to call up a seperate command window with the following, but it appears to freeze up. What am I doing wrong?
import java.io.*;
public class command {
public static void main(String[]args) {
    try {
      Process runprogram = Runtime.getRuntime().exec("C:\\windows\\system32\\cmd.exe");
      try {
        runprogram.waitFor();
      catch(InterruptedException e){}
    catch(IOException e) {
      System.err.println("Cannot run command window");
}

What about this...
    Process proc = null;
    try
      proc = Runtime.getRuntime().exec("start cmd");
      proc.waitFor();
    catch(Exception e)
      e.printStackTrace();
    }Some dukies would be nice next time ;-)

Runtime exec opens new window

Hi, I am using Runtime.exec to run an external application in Windows2000. � can read its output and i can destroy it without any problems.
But when i run my java application with javaw , the external application i run with rt.exec opens new window(without output texts, empty) . just output command windows which opens when i run the external app. from a command prompt.
If i run my java application with java.exe then then external application DO NOT open new window and run correctly. But this time my java window stays on desktop, and that's not any good for a Windows Application.
In both cases everything runs OK. The only problem is the command prompt windows.
Is there a solution when working with javaw.exe ? or hide the window when running with java.exe
Thanks all.

Eliminating the Command window in Windows

I had thought I had found a way to make the command window (the black command interpreter window in Windows that comes up when you run the JVM) go away. I used the following code:
public class StartApp {
     public static void main( String[] args ) {
          String command = "java";
          for ( int n = 0; n < args.length; n++ )
               command += " " + args[n];
          if ( args.length > 0 ) {
               try {
                    Runtime.getRuntime( ).exec( command );
                    System.exit( 0 );
               catch ( Exception e ) {
                    System.err.println( e );
                    System.exit( 1 );
          else
               System.out.println( "Format: java StartApp [-options] <filename> [arguments]" );
          System.exit( 0 );
When I run this Java app and put in another app for it to run, it runs that app just fine (it's a Swing app so I don't need the command window visible). Not only that, but it gives me the command line right after starting it (meaning the original app exited). So, theoretically, you would think I could just type "exit" to close the command window. Well, when I do type that, the command window waits until the program exits before actually closing. Manually closing the command window closes the whole program. The odd thing was, an older version (I think Java 1.1) of the JRE would allow the command window to close. But, with 1.3, it does not. Does anyone have any idea about how I could change this, or of another way to get rid of the command window?
-Sam Fahmie

Sorry, didn't put the code tag in right...
public class StartApp {
     public static void main( String[] args ) {
          String command = "java";
          for ( int n = 0; n < args.length; n++ )
               command += " " + args[n];
          if ( args.length > 0 ) {
               try {
                    Runtime.getRuntime( ).exec( command );
                    System.exit( 0 );
               catch ( Exception e ) {
                    System.err.println( e );
                    System.exit( 1 );
          else
               System.out.println( "Format: java StartApp [-options] <filename> [arguments]" );
          System.exit( 0 );

Workflow 2.6.4.0.0 configuration problem - Command window does not close

I am trying to install Oracle Workflow 2.6.4.0.0. as part of Warehouse builder using the details mentioned in this link
http://www.oracle.com/technology/obe/10gr2_owb/owb10gr2_gs/owb/lesson4/etl-mappings.htm

Is this installation complete? How to resolve this?
Please can any one help?
Thanks very much
Allan

I ran into this problem. And it took me while to get it fixed, but It does work.
First the TNS Desc is misleading. One would think that it would be host:port:sid. What it is really looking for is host:port:servicename. But if you want to use the "Change Tablespace" drop down list you need to, enter the sys password, change it to host:port:sid - Then use the drop list. And change it back before you press submit.
The second thing that I found is that it wants to use the SYSTEM tablespace as temporary tablespace. THis is becuase it is looking for a temp tablespace called TEMP. If you look a the line default_temp = SYSTEM. And if you dont supply a tablespace it wanted to change it in the wfsysgnt.sql script in the $OH\wf\sql directory. You would think that what ever the default database tbs and temp tbs is - that owf would use that. No, it wanted to change it. Oracle needs to fix this.
So here is how i fixed it. I had to create a temporary tablespace called TEMP, does not need to be big as I dropped it after it was done. Then i had to modify the wfinstall.csh script and use the install options. Not the /tablespace this option is obayed but it will try to use the SYSTEM as the temp tbs. Here is my example that I appended:
/wfacct "owf_mgr" /wfpasswd "my_owf_mgr_pwd" /debug "true" /tnsConnDesc "my_host_ip:my_port:my_servicename" /syspasswd "change_on_install" /tablespace "OWF_TBS"

Output jframe information to command window

Hi all I have a program that tracks the assets of a customer, kind of like a cart that holds cds, appliances, etc...
I wanted to be able to print out the results to the command window after they enter the number of how many items from what the user enters after they press "current status" or if they "delete" their current items. I want it to keep doing this until they close the window and exit the program. People have told me to add the System.out.println to where it says "delete" or "current status" but Im not sure how to add it in I will attach the code here. Thanks

I don't understand the question. Are you telling us you don't understand how to use System.out.println(...);? How do you debug programs without using this method?
Usually the first program someone learns to write is something like:
public static void main(String[] args)
    System.out.println("Hello World");
after they press "current status" or if they "delete" their current itemsYou want to do some activity when the above actions occur. You must already have code in your program to do something in the above cases. So simply add the System.out.println(..) statements in the same part of code.

If you want to print out to the commmend line all you need to do if put in
System.out.println(....whatever......);Add this line of code to whereever you click the button to display the users "current Status". In hte brackets is whre you put the details of what you want ot print out e.g. boxes purchaesd etc.
