Running a Batch file Using Java

hi All ,
I am executing a DOS batch file using the Java .
I am using it as
Process P;
Runtime rt = Runtime.getRuntime();
P = rt.exec("C:\\X12TST\\BATCH1.BAT ");
But in case BATCH1.bat have call to some other Batch File Say Bactch2.bat , i am not getting the output of BATCH2.BAT .
My Java Program exits as soon as it enters to the point where BATCH1 is calling BATCH2 using (call BATCH2.bat).
Any help is resolving the problem is highlt appreciated .
Please advise me if you have any alternative to solve the problem .
Thanx in advace

The Runtime.exec() should'nt be used with a .bat or .cmd file since .bat and .cmd are not really executable. I think the expected behaviour you experimentred is a process hang at the last command line of the .bat file.
Insert "echo XXX" or "net send mycomputer XXX" debug messages in your .bat, you'll see the .bat executes until last line. But the last one NEVER terminates, resulting in a hang in the Java thread doing a process.waitFor().
The only workaround (or right use of exec) is to call the cmd.exe (with FULL PATH OF cmd.exe SPECIFIED in the exec() call). An exec() calling C:\WINNT\System32\cmd.exe /C mybatch.bat should return properly, cause cmd.exe is a standard Win32 program that will be launched to interpret mybatch.bat then terminate.
PLEASE UNIX/LINUX USERS : report if the behaviour you get is the same on your plat-form, or if it is -one more- bug in win32 OS. Can you exec() a shell script direcly or do you have to exec() a "bash" or "ksh" or "csh" with you shell script as command line argument ?

Error running batch files from java source file???

Dear Friends,
hi,
this is with response to a doubt i had earlier ,
i want to run batch files from the java source file ,i tried using this code (here batrun is the batch file name that contains commands to run other java files)
try
String [] command = {"c:\\vishal\\finalmain\\batrun"};
Runtime.getRuntime().exec(command);
catch(Exception e)
but i got the following error.
java.io.IOException: CreateProcess: gnagarrun error= 2
plz. help me, i tried all combination w/o success,
in anticipation(if possible give the code after testing)
Vishal.

hello there,
i solved the prob. by using
cmd /c start filename ,but i need to pass parameters ie
cmd /c start java "c:/vishal/runfile a b" where a and b are the parameters. but it is not accepting this in Runtime.getRuntime.exec(),
any solutions ?????????

How to run batch file using trigger?

Hi, i am trying run a batch file using a trigger on a table.
say i have a table XYZ(col_1 varchar2 primary key, col_2 varchar2)
the values of col_2 keeps changing and col_1 are constant

i did some searching but couldn't find any solution. Thanks in advance

>
the script will be started around 60-70 times a day

No - as marwim said the script will be executed every time the trigger is fired. And that trigger, depending on how it is written, might be fired several times for the same transaction.
And if the trigger is fired the script will be executed even if the transaction that caused the trigger to fire issues a ROLLBACK.
Triggers are non-transactional. You need to clearly define the business rules for when the script should run. Should it run only when the transaction is COMMITTED? Or should it run if the transaction executes even if the transaction performs a ROLLBACK?
A trigger is the wrong solution for your problem.
Please clarify what the business rules are that should control the execution of the script.

Running batch files from Java using exec method

Hi,
I want to run a batch file from my Java program like this:
try {
Process proc = Runtime.getRuntime().exec("C:\\Refresh.bat");
catch (Exception e) {
MessageBox.show(e.getMessage());
Refresh.bat file contains two commands.
First one unzips certain zip file.
Second one refreshes a SQL Server database using osql utility.
Problem is that when program is run it executes only the first command and hangs on the second one.
Please help.
TIA

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.

Problem wiht Running Batch File using Runtime.exec()

I am writting one program which will create a jar file using a windows Batch file.
The main program is in the folder "d:\CmdExec.java".
The other one to which a jar file to be created is in the folder "e:\folder\HelloWorld.class"
The contents inside the "e:\folder" are
e:\folder\HelloWorld.class
e:\folder\mainClass.txt
e:\folder\run.bat
The mainClass.txt contains "Main-Class: HelloWorld"
The Run.bat file contains "jar cmf mainClass.txt HelloWorld.jar *.class"
The coding for CmdExec.java is as follows
import java.io.*;
import java.awt.Desktop;
public class CmdExec {
public static void main(String argv[]) {
try {
Desktop desktop = null;
if (Desktop.isDesktopSupported()) {
desktop = Desktop.getDesktop();
desktop.open(new File("e:\\folder\\run.bat"));
catch (Exception err) {
err.printStackTrace();
When i double click the file e:\folder\Run.bat, it will create a jar file for HelloWorld.class.
But, i want to create that jar file using the java program CmdExec.java.
When i run CmdExec.java, the batch file is opened. But it shows error as "Can't find the specified file"
But when i copy the following files to "d:\",
e:\folder\HelloWorld.class
e:\folder\mainClass.txt
the jar file is created using the CmdExec.java.
But,
e:\folder\HelloWorld.class
e:\folder\mainClass.txt
these files should be in the folder"e:\folder" only.
Can anyone Help me this Problem?
Or Anyother way for creating a jar file for one program by using another program?
Help me soon.............

Try this. It's not running a bat file. You can say it almost is a bat file.
import java.io.*;
import java.util.Scanner;
public class CmdExec {
    public static void main(String argv[]) {
        try {
            Process p = Runtime.getRuntime().exec("jar cmf mainClass.txt HelloWorld.jar *.class");
            Scanner s1=new Scanner(new InputStreamReader(p.getInputStream()));
            while(s1.hasNextLine())
                System.out.println(s1.nextLine());
            p.waitFor();
            System.out.println(p.exitValue());
            if(p.exitValue()==0)
                System.out.println("Okay");
            else
                System.out.println("Error");
        catch (Exception ex) {
            ex.printStackTrace();
}Run it in the same folder as mainClass.txt

LabView equivalent to running batch files using the "shell" command (VisualBasic)

I'm converting a VisualBasic app to LabView and am having trouble figuring out how to run a batch file with LabView.
The VB code that I'm trying to replicate is:
'UNLOAD RTX DRIVERS
Dim ProcessId As Long
ProcessId = Shell(App.Path + "\UnloadReloadRTX.bat", vbNormalFocus)
Wait 400
I haven't found a LabView equivalent to the Shell command. Any suggestions will be appreciated.
thanks,
Todd

It seems as if this question pops up every week. Use the System Exec.vi found under Funtions - Communications palette. It is the equivalent of Shell.

Can we run the batch file using simple java application

Hello sir,
we want to run the batch file using simple java application. i tried with some example, we run the exe files but not batch file.
Runtime r = Runtime.getRuntime();
r.exec("D:\\jboss\\bin\\run.bat");
My application is server will run when we run the java appliation.
any suggestion? plz give me the solutions

yes you can run html file
WEB.SHOW_DOCUMENT is a built-in that is used in Forms to call URL from a Web Form. It works much like the similar way that a link on an HTML page works and it takes two arguments, one is URL and second one is TARGET, in your case use following.
WEB.SHOW_DOCUMENT('http://channas.iil.informatics.lk:8890/forms/frmservlet?config=abc.html', '_blank');
Hope this will work for you

HOw to create a Batch file for java application and whats the use of this ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.

Running files using java

Please help, how can i run files using java.
Files such as installers, batch files, or exe files....
thanx

Dear
To run an EXE or COM or (other types of files other than BAT) use
Runtime.exec("program-file-name.exe");
while for running BAT files, always use this syntax
Runtime.exec("bat-filenane", null, "bat-file-directory");
Thats all.
If your directory name or filename contains spaces, then surround the directoryname + filename within double quotes.
