Execute batch file having gmake command

Hi, I am executing batch file having gmake command in it, when i run batch file directly it works correctly,
but when i try to execute it from LabVIEW using system Exec.vi
i got following error,
process_easy: DuplicateHandle(In) failed (e=6)
process_easy() failed to launch process (e=6)
Thanks in advance

What OS?
How are you calling it in LV?
What is in the batch file?

Execute Batch Files, DOS Commands etc. from my Java Application

Can someone show me how it works?
I dont need any return values, just execute a Batch File or a Command
Thx, Guardian

Hi Luke,
Just wanna add 2 things to what you've written. (your sample code)
Point 1pro.waitFor(); should be called before attempting the read anything from the process' InputStream if you don't want to lose anything your process might print out. When Runtime.getRuntime.exec("your_command") is executed, the resulting process is just another runaway thread unless you tell you calling thread to wait for this process to end before proceeding further. This is where waitFor() comes in.
Point 2Runtime.getRuntime().exec("C:\\command.com /C mybat.bat"); works but it is pretty platform dependent. If you need to write platform independent stuff, you could just drop the command.com stuff and go right to the batch file or the command you need to execute. I've managed to just survive with Runtime.getRuntime().exec("mybat.bat");Regards,
Noel

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

Unable to run a Batch File Operating System Command

Using XI 3.0, I am unable to run a Batch File Operating System Command After Message Processing.
My Batch file:
gpg -se -r BOA3RSKY --armor --passphrase-fd 0 %1 < C:\Progra~1\GNU\GnuPG\gpgin
My Command Line (ID scenario)
exec "cmd.exe /c C:\Progra~1\GNU\GnuPG\boagpg.bat %F"
If I execute
exec "cmd.exe /c type C:\Progra~1\GNU\GnuPG\boagpg.bat >xis.txt"
It displays the contents of boagpg.bat file in xis.txt.
I just don't understand why when I run the batch file, I would expect an %F.asc encrypted file in the same directory as the %F unencrypted file.
Any ideas?
or will I need Basis to create commands that will allow me to run GPG from XI Command Line?

How to execute batch file from JSP

hi frens !
i wanna know how to execute batch file from my JSP.i am using exec() method to get call the batch file. but its not working ....plz help
here mine code:-
File F = new File("C:/var.bat");
     try{
      if (F.exists())
        Runtime rt = Runtime.getRuntime();
        String url=F.getAbsolutePath();

}Thanks and Regards
Allwyn

You might improve your chances of getting help if you do two things:
1) Explain what "not working" means.
2) ChangeSystem.out.println(IOEx); to IOEx.printStackTrace(); (in the eventhat is in fact related to "not working").

Executing batch files from websevice using ODI OS Command

Hi,
Is it possible to execute the batch files using odi os command from webservices.
We have developed a webservice, which passess some parameters to one batch file and after that we executing the same batch file in package using odi os command. In opeartor is showing as running, it never ends.
But if we run the same package from designer, it is executing successfully. Also the same web service is working fine for executing non batch scenarios.
what could be the problem??
We got one possible reason for failure...
For executing the batch from web services, we need read and executable permissions on the drive where batch sits.
We are logging into ODI using SUPERVISOR. How to give the permissions to SUPERVISOR as we are having windows authentication.
Edited by: Naveen Suram on Dec 17, 2009 8:07 PM
As a work around, can we use ODIOSCommand instead of OS Command. But it is asking for starting event? Whether both the commands does the same functionality??

From the FAQ:
2. How do you launch an external program on a Microsoft Windows platform from a program developed on the Java [tm] programming language?
The following will launch notepad in Microsoft Windows NT:
Runtime.getRuntime().exec("cmd /c notepad.exe");
To launch a program in Microsoft Windows 95/98 use:
Runtime.getRuntime().exec("c:\\windows\\notepad.exe");
The Runtime class allows interaction between a program and its environment. The first string command instructs the command line interpretor, cmd to open up the calculator application.
The exec() methods do not use a shell; any arguments must have the full pathname to the shell as well as the command itself.
For example, to run a shell on the UNIX� platform, type:
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("/usr/bin/sh -c date");
To run a batch file under Microsoft Windows 95/98:
Process p = rt.exec("command.com /c c:\\mydir\\myfile.bat");
To run a batch file under Microsoft Windows NT:
Process p = rt.exec("cmd /c c:\\mydir\\myfile.bat");
where 'cmd' and 'command.com' are the command-line interpreters for Microsoft Windows machines.
The Runtime.exec() methods might not work effectively for some processes on certain platforms. Special care should be taken with native windowing, daemon, WIN16/DOS process or some shell scripts.

Error executing batch file within web application

Hi all,
I am trying to execute a batch file from within my web application (struts 1.2).
The batch file is being kept inside the 'src' folder. The batch file contains only one command to open NOTEPAD.
The code inside my Action class is:
URL url = getClass().getResource("/test.bat");
java.io.File file = new java.io.File(url.getPath()) ;
String path = file.getCanonicalPath();
r.exec(path);
I have deployed this on tomcat and get an error like this:
java.io.IOException: Cannot run program "C:\Program%20Files\Apache%20Software%20Foundation\Tomcat%206.0\webapps\CIGTAFAPP\WEB-INF\classes\test.bat": CreateProcess error=2, The system cannot find the file specified
The problem is not with the batch file because when I try to execute the file directly from the classes folder, it opens up the notepad editor.
I have a specific requirement where I need to create/read this batch file from within the project structure.
Can someone please help me with this?
Regards

The entire content of the file is as below:

Two questions: Executing batch files and executing a JAR on boot-up.

I'm working with Windows XP and and currently I'm having a friend test this on Vista as well. I can't seem to find how to execute a batch file using Runtime.exec(). So far I've been passing the absolute pathname of the batch file as the argument to exec(), but it doens't seem to run, so I'm assuming there's another way.
Second question, how do I get a JAR file to start running whenever the user turns on the PC?
Thanks.

Execute batch file

Hello,
I have a simple and short batch file I am trying to execute from SQL server. The SQL database I am connected to is my local instance. The script I am using is as below:
EXECUTE [master].[dbo].[xp_cmdshell] 'C:\Users\Jdoe\Desktop\Test.bat'
The batch file is located at the path listed above and contains the below:
SchTasks /query /fo csv > I:\Schedtask.txt /v /s reports.xyz.org
The above command line code connects to a remote machine and gets the list of all scheduled tasks. Please note that executing the batch file by double-clicking on the icon works without issues. When I try however to run the SQL listed above, I get the below:
output
NULL
C:\Windows\system32>SchTasks /query /fo csv /v /s reports.xyz.org 1>I:\Schedtask.txt
The system cannot find the path specified.
NULL
What am I doing wrong. I am expecting the SQL to execute de batch file which should create a output file at the specified location but it doesn't.
Thanks for helping

Try to use UNC path (\\server\share\file_path). Also make sure that the doamain account used as task owner has the proper rights on the source and destination

Can Java execute batch file outside of current JVM in separate process tree

Hi,
Does anyone know how to run programs from Java as separate processes that will not die when the spawning java program exits (JVM exits).
The problem I have with using Runtime.exec is it spawns only child processes under the current running JVM, thus when the origonal program that called Runtime.exec ends so does all child processes.
Basically I want to start a DOS batch file from my Java application, my Java application will then immediately exit (calling System.exit(0) ). The batch program will continue to run, its does some file clean up, create's some new files and deletes the old jar (containing the main app), it then rebuilds the main app jar and and executes the main class and then exits itself.
I've also tried the apache.tomcat.jni.Proc :-
long pool = Pool.create( new Long(0).longValue() );
long pa = Procattr.create( pool );
Procattr.dirSet( pa, "c:\\temp\\updater\\");
Procattr.cmdtypeSet( pa, Proc.APR_SHELLCM );
Procattr.detachSet( pa, 1 );
long proc = Proc.alloc( pool );
Proc.create( proc, "test.bat", new String[]{"test.bat"}, null, pa, pool );
System.exit(0);
The detach option doesn't work, if I take it off then the bat file runs and stops the JVM exiting, if I leave it in the batch file never gets called.
Is this possible in Java. Can java start master process on Windows XP JDK1.5+?
Cheers
Chris.

Well I found the answer elsewhere (java.net) thought I'd post it here for future visitors who might be experience the same problem.
Basically Runtime can do this however it must be done the following way :-
The java:-
public class Main {
    public static void main(String[] args) throws Exception {
        Process p=Runtime.getRuntime().exec("cmd /c c:\\test.bat");
        System.out.println("done");
        System.out.println("quitting");
        System.exit(0);
}The batch:-
@echo off
PING 1.1.1.1 -n 1 -w 5000 >nul
java -cp "c:\ " MainThe important line that makes the whole thing work is :-
@echo offIf this line is missing then the whole things locks up (must be the io streams getting used)
Also this code can not be run from an IDE (well at least not from Intellj) as it also locks up.
It must be run from a command prompt or jar.
Also note that any commands in the batch file must have there output redirected to "nul" otherwise Windows kills the cmd as soon as it trys to output to a dead stream (dead because the Java has exited). for example :-
@echo off
PING 1.1.1.1 -n 1 -w 10000 >nul
cd %1
del /F /Q *.* >nul
move /Y new\*.* >nul
RD /Q /S new >nul
PING 1.1.1.1 -n 1 -w 1000 >nul
java -cp "c:\ " Main
exit

Problem Executing Batch File

I wrote out a java class that I tried using cfobject to call. It didn't work. So I wrote a batch file to call the java class. The batch file works, but NOt when I have coldfusion call it. Nothing happens, no error... nothing. I thought it might be a permissions issue, but I tried changing permissions for coldfusion although I may have doneit wrong since I'm not too familiar with Vista. Can anyone offer advice on what I can do. Its a simple java class and I can't get it to run. no errors in the log. There isn't much for me to go on. All I know is that the class and batch file work fine if Coldfusion doesn't call them.

Amosl wrote:
To limit the problems with the class itself and cfobject, I've created a batch file to run the class. The batch file runs the class fine, so long as I execute the batch via command line. But coldfusion doesn't execute the batch with cfexecute. the same exact problem with absolutely no error messages.
Unfortunately, cfexecute is not the easiest tag to debug. In my experience sometimes it confuses more than clarifies. But trying it is not a bad idea from a troubleshooting point of view.
However, if I create a java class in the same folder that doesn't write to the system and only returns variables, it works fine. This indicates the class path is set correctly and that cfobject does work.
Yes, I would agree.
It does sound like it might be a permissions issue. But I have little experience with Vista, so there may well be another cause. Since it sounds like you are just testing a very simple java class, can you post the code for the class itself as well as the exact cfexecute code you are using? I could test it on another operating system. Just to see if there is some obvious problem.
Amosl wrote:
From the 100's of pages I've read online with people with similar problems, this seems to be a permissions issue. however, I've set Coldfusion to run as me, the administrator and only person who uses this computer. It is no longer running as local system.
However, this didn't fix anything. My only guess is that perhaps I've no set it to run as me correctly. But I have no way of testing this. Windows logs show no error messages either. Is there any way to have coldfusion show me what user its trying to execute the batch as.
I believe the user account can be obtained from the java system properties. Try:
<cfset sys = createObject("java", "java.lang.System")>
<cfoutput>
user.name = #sys.getProperty("user.name", "not found")#<hr>
coldfusion.classPath = #sys.getProperty("coldfusion.classPath")# 
</cfoutput>

Executing batch File from Jsp

I want to execute a batch file which is located at d:\build from a jsp
I also want to give parameters to batch file.
Actually my batch file is demo.bat and i want to execute this command via jsp
demo Compile dev

in a word - don't. that's not what jsps are for.
you sound confused about where jsps actually run. get client and server straight in your head and then think about it again.
