Java and batch files

i want to launch my application by a batch file, whit this script:
@echo off
"C:\j2sdk1.4.2_08\bin\java.exe" -cp "C:\Documents and Settings\Intrepido\Desktop\my tesina" BSServer 2103
pause
my application as first operation, read from a txt file some row just to configure himself.
if i launch my application from DOS, writing the path manually, my application does function correctly, instead, launching it from batch file, the first row read return a null value; (i use the RandomAccessFile class and the readLine() method to access file...)
moreover, since my application is a JFrame class, i've associate some icon to the buttons of the window. starting the application manually from DOS the icons are benn loaded, instead, launching the application from the batch file, the icons are not loaded...
Help me please...
and sorry for my bad english...

and sorry for my bad english...Since it is a java forum, I suppose that your app is a java app, isn�t it?
First, define the MANIFEST.MF of your application, that must call the class that contains the famous public static void main(String[] args) method. If you haven�t made this method yet, make it. This method must initialize your app. If you don�t know how to create or how to configure the MANIFEST.MF file, read the articles below:
http://java.sun.com/developer/Books/javaprogramming/JAR/basics/manifest.html
http://java.sun.com/j2se/1.3/docs/guide/jar/jar.html
Don�t forget to configure the reference of some jar files required by your app in the MANIFEST.MF if it is necessary.
Second, create the batch file. The content of this file is simple. It has has to be like below:
java -jar MyJarFile.jar
Where MyJarFile.jar is your jar file. Then, put this batch file in the same directory of the jar file and double click it. Finish! Your app will be executed as you want.
Of course, first of all, you have to configure the java environment variables in order to this app works well (JAVA_HOME, PATH, CLASSPATH, etc).
It is just one manner to do what you want. There are other ways to do it, of course.

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

Java and Batch File Issue - need urgent help

I have a java program which calls a batch file. This batch file calls another java program. I want an option so that I can close this java program from main program.
If i try process.destroy then it will call batch file and not java program.
I can't go away with batch file.
I will appreciate if someone can help me.

Hi, Thanks for the help but this doesn't seem solving my problem completely. I will appreciate if you can help more.
I will explain you the scenario -
1. There is java program provided as an external program to me.Only changes things slightly.
2. This java program is called using batch file. When batch file is started this java program starts and listens on a socket for incoming data.I would want to wrap the launch of this java program in another JVM so we can use process.destroy().
3. I am writing a program to check performance of the above java program. I want to call this java program from my program in a loop having some varying config data. When I run the loop first time I create a batch file at run time which executes the batch file provided by vendor. This batch file starts the socket. Once my message list is over then my loop goes to executing the batch file again with different config parameters. But this time I run into issue because my previous java program is not killed after message sending was over.Would it be acceptable to mung the 3rd party batch file to insert a wrapper JVM?
Even if i use threads I don't think I can get rid of batch file.I did not suggest getting rid of batch files.
So, I need to find a way so that when any iteration of loop is over then this socket program is killed. These 3rd party java programs - do they not have a "terminate" command you can put at the end of your message list?
Even if i closed the socket from my client program that doesn't help because server is still listening and waiting for new client.
I need to kill server which was started by batch file.On Linux it would be fairly simple to modify your batch file to determine what the process id is and send the process a signal to terminate it.
Not sure what you can do on Windows.

How do I start a batch file and check it's status?

First of all I want to say I am a beginner in Java.
I am working on an server side application that starts batch files (for database filling). After it starts the batch (.bat) file it has to check the status and write it in the database.
The problem I run into the combination of starting the batch and checking the status.
So far I have found out that I can run the batch file with starting up an process with the Runtime.getRuntime().exec command. What I haven't found out if it is posible to check the status of this proces in any way.
I also found out that with using thread commands like isAlive I can check the status of a thread, but not of an process. And I understand that a thread can't start an batch file.
So could anyone please help me on my way. Am I doing something wrong? Is any of the above info incorrect? Or am I on the right way? And if I am on the right way what is the next step? Thanx in advance.

The problem I run into the combination of starting
the batch and checking the status.The exit status is only set onve the process completes.
process.exitStatus()
I also found out that with using thread commands like
isAlive I can check the status of a thread, but not
of an process. And I understand that a thread can't
start an batch file.Everything run in java is run from a thread. Only threads can do anything. The default thread is called "main"

To catch exception from a batch file

Hi,
I am running a batch file using java,the batch file is used for running SQL Loader.It is working OK,but I am unable to catch any exception or sucess message.Can anyone help?
regards,
Anshuman

Have your Java main() catch Throwable and then use System.exit(an errror code); inside the catch. Your batch file can then examine the process return code.

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

Java.io.filepermission error while executing a batch file from java prog

Hi,
i want run a java program which executes a batch file, both are in a jar file. while am trying this using webstart it shows error:access denied java.io.filepermission <<ALL FILES>>execute. why this happens how to rectify this.

Vinod

Clearly, it would be a security vulnerability to be able to do such a thing from the web w/o user granting trust to the application.
Java Web Start applications run in the Java SE secure sandbox unless they have been granted all-permissions by the user:
1.) sign all jar files.
2.) add <security><all-permissions/></security> to the jnlp file.
The user would then be prompted to grant trust to the applications.

Closing Console window while running Java application from Batch file

Hi all,
I have made a small application using Java swings,now i have made a jar file of my application and calling this jar file through batch file,when user clicks on that batch file it runs "java -jar applicationname.jar" command,but problem is that when i run that file from batch file it opens Dos console window at baclk of the screen which looks weird for a desktop application,i dnt want that Dos console window visible at the backend while my application is running,i have searched regarding this on google but found nothing usefull,if anybody can please help regarding that it will be a great releif for me,i have been stuck on this problem from last two days.
Thanks.

That'll pop up another consoleI'm under the impression that the console window he is seeing is the one which cmd.exe opens when it is executing the batch file. And that batch file won't return until the java process has completed because he didn't start it in the background to let the batch file continue and terminate.
So I don't think just simply substituting java with javaw will do much good either. Still think he needs a "start" command in that batch file.
So now he can try:
start java -jar ...
or
start javaw -jar ...Fair point

How to pass arguments to a batch file from java code

Hi
I have a batch file (marcxml.bat) which has the following excerpt :
@echo off
if x==%1x goto howto
java -cp C:\Downloads\Marcxml\marc4j.jar; C:\Downloads\Marcxml\marcxml.jar; %1 %2 %3
goto end
I'm calling this batch file from a java code with the following line of code:
Process p = Runtime.getRuntime().exec("cmd /c start C:/Downloads/Marcxml/marcxml.bat");
so ,that invokes the batch file.Till that point its ok.
since the batch file accpets arguments(%1 %2 %3) how do i pass those arguments to the batch file from my code ...???
%1 is a classname : for ex: gov.loc.marcxml.MARC21slim2MARC
%2 is the name of the input file for ex : C:/Downloads/Marcxml/source.xml
%3 is the name of the output file for ex: C:/Downloads/Marcxml/target.mrc
could someone help me...
if i include these parameters too along with the above line of code i.e
Process p = Runtime.getRuntime().exec("cmd /c start C:/Downloads/Marcxml/marcxml.bat gov.loc.marcxml.MARC21slim2MARC C:\\Downloads\\Marcxml\\source.xml C:\\Downloads\\Marcxml\\target.mrc") ;
I get the following error :
Exception in thread main java.lang.Noclassdef foundError: c:Downloads\marcxml\source/xml
could some one tell me if i'm doing the right way in passing the arguments to the batch file if not what is the right way??

1 - create a java class (Executer.java) for example:
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
public class Executer {
     public static void main(String[] args) {
          try {
               for (int i = 0; i < args.length; i++) {
                    System.out.println(args);
               Class<?> c = Class.forName(args[0]);
               Class[] argTypes = new Class[] { String[].class };
               Method main = c.getDeclaredMethod("main", argTypes);
               // String[] mainArgs = Arrays.copyOfRange(args, 1, args.length); //JDK 6
               //jdk <6
               String[] mainArgs = new String[args.length - 1];
               for (int i = 0; i < mainArgs.length; i++) {
                    mainArgs[i] = args[i + 1];
               main.invoke(null, (Object) mainArgs);
               // production code should handle these exceptions more gracefully
          } catch (ClassNotFoundException x) {
               x.printStackTrace();
          } catch (NoSuchMethodException x) {
               x.printStackTrace();
          } catch (IllegalAccessException x) {
               x.printStackTrace();
          } catch (InvocationTargetException x) {
               x.printStackTrace();
          } catch (Exception e) {
               e.printStackTrace();
2 - create a .bat file:
@echo off
java -cp C:\Downloads\Marcxml\marc4j.jar; C:\Downloads\Marcxml\marcxml.jar; Executer %TARGET_CLASS% %IN_FILE% %OUT_FILE%3 - use set command to pass variable:
Open MS-DOS, and type the following:
set TARGET_CLASS=MyTargetClass
set IN_FILE=in.txt
set OUT_FILE=out.txt
Then run your .bat file (in the same ms dos window)
Hope that Helps

How to exit batch file after launching java application

hello, I have created a simple java application and a batch file to launch the application. but when execute the batch file the application execute but the batch file still
appear. I want to launch the application and immediately close the batch file after the application appears.
Best Regards,
Boulebtina

In the batch script use the "START" command to start the program. To use it you need to have the script browse to the application directory first as shown below:
c:
cd MyApplication\ApplicationFolder
START myApp.exe
exitThis will start an application that is stored in C:\MyApplication\ApplicationFolder\myApp.exe. I use this quite a bit and works well for me.

How to execute java batch file in JSP

Ain't gonna happen.
its taking more time to execute .... that's y is there any other option to execute .exe file other than Runtime.getRuntime().exec("filename");Write proper English and you may be taken more seriously.
1) it's not "taking more time to execute", whatever that's supposed to mean.
2) there's no other way to execute something. Not that you should every use even that way anyway
3) whenever you start thinking of executing external programs from Java, start thinking of not using Java in the first place.

Batch file to start and stop

Hi All,
Can we create a batch file to start and stop the services. I need to start all the services like shared, essbase, eas, planning, webanlysis and financial reporting, and at also need to stop them using windows batch file.(Using windows 2003 server....service pack 1). Any help would be appreciated.
Thanks

Hi,
The simplest script would be something like this. Save it as a .bat file, set all your services to manual and then set up a scheduled task to run this script when the computer starts.
