Running .bat files from java applications

Has anyone tried to run a .bat file from a java application?
I know I can run java commands by getting the application's runtime, but I've a number of *.bat files I like to run from the application without having to extract the commands from the .bat files.
thks,

Crikey! You were answered very shortly after you posted your question, and you STILL haven't bothered to come back. And are you going to create a new userid the next time you ask a question, since bat2004 seems tied to this particular question?

Running exe files from java applications

Hello All,
Is it possible to run executable files from java applications?
I need to run an exe file on the client from the server machine, the exe could reside on either the server or any other machine on the LAN. Is it possible to specify the path of where the exe resides, and run it on a client machine?

HI,
I tried to launch a MS Word application using runtime.exec but it gives me some problem
The foll. code to launch a txt file using notepad works.
Runtime rt = Runtime.getRuntime();
String[] callAndArgs = {"notepad.exe","C:\\coo7\\wizard.txt"};
Process child = rt.exec(callAndArgs);
However, oif I try to launch a MS Word application, it asks for the entire path of WINWORD.exe, (unlike just specifying notepad.exe as the first argument in String[] callAndArgs) and this can vary from one machine to another.. how do I get around this?
The foll. code snippet works but the complete path of where WINWORD.exe might be installed on any machine, is not fixed:-(
Runtime rt = Runtime.getRuntime();
String[] callAndArgs = {"C:\\Program Files\\Office\\Office10\\WINWORD.exe","C:\\coo7\\wizard.doc"};
Process child = rt.exec(callAndArgs);
Any idea/suggestions pls..

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)

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.

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 file from Java

how would i go about calling a batch file in java?
a button is clicked that says "RUN" and then I want to run a batch file

Hi !!!
Im new to this forums but I think I can help you
You can execute a separate process by using the class Runtime. In this example I execute one batch file located on the same directory the Java App is in.
class Test
     public static void main(String a[])
          System.out.println("Executing Batch File");
          try{
          Runtime.getRuntime().exec("Runme.bat");
          catch(Exception ex){}
}I hope that could help

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 .EXE file from Java

Do you know, how run an .exe file, for example Internet Explorer or other program, from Java application?
It's very important for me.

Too run external program and pass string arguments see class java doc
of java.lang.Runtime method exec . You see online or download or
rename src.jar to s.zip EXTRACT and see
exec
public Process exec(String[] cmdarray,
String[] envp)
throws IOException
Executes the specified command and arguments in a separate process with the
specified environment.
This is a convenience method. An invocation of the form exec(cmdarray, envp)
behaves in exactly the same way as the invocation exec(cmdarray, envp,
null).
Parameters:
cmdarray - array containing the command to call and its arguments.
envp - array of strings, each element of which has environment variable
settings in the format name=value, or null if the subprocess should inherit
the environment of the current process.
Returns:
A new Process object for managing the subprocess
Throws:
SecurityException - If a security manager exists and its checkExec method
doesn't allow creation of the subprocess
IOException - If an I/O error occurs
NullPointerException - If cmdarray is null, or one of the elements of
cmdarray is null, or one of the elements of envp is null
IndexOutOfBoundsException - If cmdarray is an empty array (has length 0)
See Also:
ProcessBuilder
getRuntime
public static Runtime getRuntime()
Returns the runtime object associated with the current Java application.
Most of the methods of class Runtime are instance methods and must be
invoked with respect to the current runtime object.
Returns:
the Runtime object associated with the current Java application.
