I need to call a batch file from java and pass arguments to that Batch file

Hi,
I need to call a batch file from java and pass arguments to that Batch file.
For example say: The batch file(test.bat) contains this command: mkdir
I need to pass the name of the directory to the batch file as an argument from My Java program.
Runtime.getRuntime().exec("cmd /c start test.bat");
How to pass argument to the .bat file from Java now ?
regards,
Krish
Edited by: Krish4Java on Oct 17, 2007 2:47 PM

Hi Turing,
I am able to pass the argument directly but unable to pass as a String.
For example:
Runtime.getRuntime().exec("cmd /c start test.bat sample ");
When I pass it as a value sample, I am able to receive this value sample in the batch file. Do you know how to pass a String ?
String s1="sample";
Runtime.getRuntime().exec("cmd /c start test.bat s1 ");
s1 gets passed here instead of value sample to the batch file.
Pls let me know if you have a solution.
Thanks,
Krish

Calling nested Batch files from Java

Hi,
I have a java program which loops through a list of batch files, executing each one. This works fine. My problem is that each batch file I execute contains a call to execute a further batch file.
The second(nested) batch file never gets run. The java program completes sucessfully though. Any ideas of a way around this?
Code:
while (batFileToken.hasMoreTokens()){
    String batFileName = batFileToken.nextToken();
    Process process = load.exec("cmd.exe /c "+batFileName);
    process.waitFor();
}Each batFileName it executes contains the below command:
call test.battest.bat never executes.

Check this link..
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
the way to make sure process is completed.. is
try{
Process proc = Runtime.getRuntime().exec(optimizer.exe);
StreamGobbler errorGobbler = new StreamGobbler(proc.getErrorStream(), "ERROR");
StreamGobbler outputGobbler = new StreamGobbler(proc.getInputStream(), "OUTPUT");
errorGobbler.start();
outputGobbler.start();
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
catch (IOException ex1) {
System.out.println("Error in Starting Optimizer");
catch (Throwable t) {
t.printStackTrace();
class StreamGobbler extends Thread {
InputStream is;
String type;
OutputStream os;
StreamGobbler(InputStream is, String type) {
this(is, type, null);
StreamGobbler(InputStream is, String type, OutputStream redirect) {
this.is = is;
this.type = type;
this.os = redirect;
public void run() {
try {
PrintWriter pw = null;
if (os != null)
pw = new PrintWriter(os);
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ( (line = br.readLine()) != null) {
if (pw != null)
pw.println(line);
System.out.println(type + ">" + line);
if (pw != null)
pw.flush();
catch (IOException ioe) {
ioe.printStackTrace();

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

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.

then i tried to run it in application server. its still not running.
can you tell me what i have to do within my bean class? or can you suggest any solution?

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.
