Call .bat file from java code

I need to call an application that uses a .bat file to execute from a java program. Is that possible?
This is the .bat file:
importcli.exe ciaf2735 C:\Importcli\files\SAI2735*.txt
importcli.exe ciaf2735 C:\Importcli\files\CI2735*.txt
importcli.exe ciaf2735 C:\Importcli\files\SC2735*.txt
importcli.exe db1800 C:\Importcli\files\*.mdb

Hmmm, I wonder what would happen if there were a web search engine and you could research like this:

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.

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 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.

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 Call .XDO file From Java Program

Hi,
I have developed a report in using BI Publisher version 10.1.3.
I created the report and it only created XDO files. If I want to call XDO file from Java program how I can do that.
What are the APIs available to do that.
Thanks
-Ashutosh

Hi,
the JavaAPI didn't work with the xdo-Files. But you can create a proxy stub for the Web Service API of BI Publisher which uses the xdo's in the repository.

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

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)
