Executing a .bat file from java code

Im writing a utility and i need to be able to create and execute a .bat file from my program. I can create the .bat file fine but when i try to execute it nothing happens. I tried to use the following line of code to try to execute the .bat file (called make.bat) :
try
String parameterString = "\"C:\\WINNT\\System32\\cmd.exe\" C:\\ITS_Test\\make.bat";
Runtime.getRuntime().exec(parameterString);
catch (Exception e)
System.out.println(e);
The Runtime.getRuntime()exec() method worked fine when trying to execute an excel file but for some reason it dosen't want to work for the DOS prompt. Any ideas?

Thanks everyone for all the replies.
I have tried all the above with no luck. Im using netbeans, does anyone think that it could be a problem with the IDE.
I tired the following code :
String parameterString = "cmd.exe /C \"C:\\ITS_Test\\make.bat\"";
Process pr = Runtime.getRuntime().exec(parameterString);
pr.waitFor();
This code does not throw any exceptions but just hangs. I also tried:
String [] parameterString = {"cmd", "/c", "C:\\ITS_Test\\make.bat"};
Process pr = Runtime.getRuntime().exec(parameterString);
pr.waitFor();
and:
String parameterString = "\"C:\\WINNT\\System32\\cmd.exe\" \"C:\\ITS_Test\\make.bat\"";
Process pr = Runtime.getRuntime().exec(parameterString);
pr.waitFor();
with the same result. Does anyone know why it just hangs and nothing happens (no exceptions thrown)?

Running .bat files from java code

Dear Forum,
I have seen numerous postings on the web about this question, still I have found no answer that works (for me)
I�m trying to run a simple .bat file from a piece of java code , however it does not work. No error message , but still.
Does anyone have a tip?
best regards
temuj
try{
String cmd = "cmd.exe C:\\mybat.bat";
Runtime.getRuntime().exec(cmd);
catch(IOException e){System.out.println("ERROR: "+e);}Message was edited by:
temujin

"cmd.exe C:\mybat.bat" is being passed to the OS for execution
what happens when in a terminal/dos window you execute letter for letter:
cmd.exe C:\mybat.bat
The output will be identical to what is happening when java makes this call.

How to run Executables or .bat files from Java?

Hi!
I need to open a Web Browser from Java App.
Please, help me to do this without calling JNI
-or-
provide me with sample which works with
Runtime.execute() method.
I have done full permission:
grant
     permission java.security.AllPermission "","";
};Thank You in advance!

To run any command from java code, the method is
Runtime.getRuntime().exec( myCommandString )
Where, myCommandString is something like "/full/pathname/command".
If the pathname contains spaces, e.g. "c:\program files\windows\notepad", then enclose it in quotes within the quoted string. Or pre-tokenize them into elements of an array and call exec(String[] cmd) instead of exec(String cmd).
From JDK1.3 there are two new overloaded Runtime.exec() methods. These allow you to specify starting directory for the child process.
Note, there is a gotcha associated with reading output from commands. When the runtime exec's the process, it passes to it 3 streams, for stdin, stdout, and stderr; the out and err are buffered but the buffer size isn't very big. When your process runs, it reads (if needed) from in, and writes to out and err.
If it doesn't write more than the buffer-size, it can run to completion.
But if it tries to write more data to one or the other stream than the buffer can hold, the write blocks, and your process hangs, waiting for you to empty the buffer so it can write some more.
So after the exec call, get the streams, and read from them in a loop until they both hit end-of-stream (don't block on either one, just read whatever is available from each, each loop iteration).
Then when the streams have ended, call the process.waitFor() method to let it finish dying.
Now, here is a code snippet how you achieve this.
String strCommand = "cmd.exe /c " + strCommand;
boolean bWait = true;
//execute the command
try
     Runtime r = Runtime.getRuntime();
     Process pr = r.exec(strCommand);
     Process pr = r.exec(callAndArgs);
     BufferedInputStream bis =new BufferedInputStream(pr.getInputStream ());
     int c=0;
     /** Outlet for IO for the process **/
     while (c!=-1)
          c=bis.read();
     /**Now wait for the process to get finished **/
     if(bWait == true)
          pr.waitFor();
          pr.destroy();
catch(Exception e)
     System.out.println("Could not execute process " + strCommand);
     return(false);

Running Oracle startup or shutdown bat file from Java code

I have two bat files for the startup and shutdown of Oracle instance which works fine from the command prompt. But my requirement is to run it through a Java program. Please reply with full Java code. Also mention how I would get the status of the bat files that it is successfully executed or not and if not what is the error.

Your program is working fine, but there is another problem. What's happening now is I have to open the Login screen after the startup of oracle server is complete, but the next line of my program after Runtime.exec is the LoginScreen.show which immediately shows the login screen after executing Runtime.exec and when I am giving the login name and password and press enter, it shows Oracle not available exception, because the startup process is still in progress. I want to stop the execution of my next line of code until and unless my process of Oracle startup is complete.

How can I execute a .bat file from inside a java application

I have a .bat file which contains an executable file(.exe) and some input and output file names. What commands can I use to execute this bat file from my java application.

After raeding tkleisas' reply; i am trying to invoke another application (which can be invoked from the command line) by using a batch file and trying Runtime.exec for executing a batch file.
My current code is:
Runtime runtime = Runtime.getRuntime();
Process trialProcess;
trialProcess = runtime.exec("cmd.exe /C start C:\\guns.bat /B");
And my guns.bat looks like:
cd C:\CALPUFF
echo trial
start calpuff.exe CALPUFF.INP
This is not working for me and i get the following in the error stream of the trialProcess:
Error :
The system cannot execute the specified program.
Process finished with exit code 1
Has anyone come across something like this and know what's wrong with this one??
thnx

Starting exetutable java file from java code

Hi I was wondering how I can start a executable java file from java code?
thanks

Hi Mkaveli,
Yes, it's possible. If you have a JAR executable, you've just to call the main method of its starter class. For a simple executable class, just call its main method.
This way :
SomeStarter.main(null); // if there's no argumentSmall precision : the executable JAR or class must be specified in the classpath of your application.

How to modify an existing xml file from java code.

Hi
I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
For example if xml file(studlist.xml) is as below:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
Now suppose i have set name to victor using student.setName,
and set age to 20 using setAge from javacode,
the new xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
<Student>
          <Name>victor</Name>
          <Age>20</Age>
     </Student>
As observed this is not a valid xml file.But how can i modify without any errors?

I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
// gets the root element of the specified file (code not shown)
Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
// write a new student element
Element student = document.createElement("Student"); // creates the new student
rootElement.appendChild(student); // ***appends it to the root element***
Element name = document.createElement("Name"); // creates the name element
name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
student.appendChild(name); // appends the name to the student
Element age= document.createElement("Age"); // creates the age element
age.appendChild(document.createTextNode("26")); // adds the age text to the age element
student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file

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

Bat files from java application..its urgent pls help me

hi
My java application tries to execute the bat file, the code followes
Runtime runs = Runtime.getRuntime();
runs.exec("e:/customisation/test.bat");
The bat file contains commands to copy files from one folder to another
and some dos commands, but the commands are not executing. If i tried the bat file with some exe's like notepad its working well, but not working with dos commands.
thanks in advance
nisam

Hi
Your batch file will be working actually. But no output will be seen in the console window.
For example I had created a batch file with the folowing code
echo This is test
copy test.bat test1.bat
pause
Even though I can't see the messages in the console, it executed when called using
Runtime runs = Runtime.getRuntime();
runs.exec("hi.bat");
where hi.bat contains the above code.
If you want to see the output messages also in the console, you have to redirect the outputstream to the current console. One such class this does is available somewhere in Java(I don't exactly remember :-( ). I think it is StreamPluginThread.java

Running bat-files from Java

Hello,
I have been trying to launch a bat-file from my Java code, running under windows, but with no success.
Here is my simple code:
Runtime.getRuntime().exec(new String[] {
"C:\\temp\\test.bat"
});This does nothing at all and generates no exception. Any suggestions?

It seems java has a real problem with this... if you
want to run another java program, for instance, you
cannot do that either with String cmd="cmd.exe /C
java myProgram"
I need to pass parameters from one program into the
program I'm going to open using java, that is why I
need to call it from my first program. It can open
executables and shortcuts, but has a real big problem
doing things with the command line.No it doesn't have a problem with it. You just must be doing something wrong. By the way, since "java(.exe)" is already an executable, there's little value in wrapping that by the "cmd.exe" shell (unless you want to use the command shell for some reason such as passing the redirector (>) symbols to it to let it redirect stdout / stderr to a file)

Executing the .bat file under java

Hi,
I have a batch file which will do some useful stuffs
like compilation of jar file, deploying the ejb's under
WebLogic container etc.
I called the batch file under windows environment, it
used to display the console without any processing
on it.But similar stuff with shell script works fine on
Linux OS.
How do I execute the batch file from Runtime?

We use
Runtime.getRuntime().exec("c:\\path\\to\\batch.bat");
If that doesn't work, try "cmd /c c:\\path\\to\\batch.bat".
You might have to capture the output from the process from Java to make sure it works correctly. And yes, the downside is that it will bring up an empty command prompt when you run it under Windows 95,98,Me... not a lot you can do about that, it's avoidable under NT,2K,XP with a bit of trickery though.
