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.

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)?

Using FDM can we execute the .bat file

Hi,
I am trying to automate the load process, ie I want to load data through FDM into essbase and once the data is loaded I want to run a bat file through which in the essbase the agg scripts will run.
So Can I write it in the Aftload a script to call the .bat file which has the agg scripts in it.
Is it possible to do?
Can anyone help me giving idea to me on this?
Thanks,

If i may, i would like some help on this subject.
i tried both methods and they both work from the WB. but as soon as i tried to use them on the web, nothing happens. i tried to write that in an event or as a stand alone task in task flow but no results
API.DataWindow.Utilities.mShellAndWait CStr("C:\Hyperion\products\FinancialDataQuality\SharedComponents\export.bat"), 0
this bat file works as a cmd, a bat in win explorer or in the WB, but i can not seem to find a way to include it in a script that i can use from the web. i tried batch, Importaction,...any suggestion?

Where to find out the log file under java developer role

Hi,
I have some application created in NWDS. While running it after the PAR deployment and all. some exception is thrown. the exception iD is given. I was trying to find out wher the log files are located in the portal so that I can analyze the exception.
I think it is under the java developer role....but under that......I checked the log viewer tool and all.....but exactly where the log files would be located. so that with the exception ID , I can search and find out the log for the particular exception.
any ideas?
Thanks in advance.

Hi Steelman,
Use the search option in log viewer for this purpose. In the server it would be located in
<i>usr/sap/sid/jc00/cluster/server0/logs</i>
Hope this helps.

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);

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

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

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

How to execute .bat file through java?

I already create a batch file to pull & push file. Now, i want to execute this .bat file java.I got this example but it doesnt work. Did i missed something or do we have the better one?
import java.lang.*;
import java.io.*;
public class Loadfile
public static void main(String args[]) throws IOException
Runtime load = Runtime.getRuntime();
r.exec("C:\\pull.bat");
}

For Runtime,i'd change it to:
Runtime load = Runtime.getRuntime();
        String cmd = "C:\\javaclass\\copytemp.bat";
        Process proc = load.exec(cmd.toString());Is it right? But still can't work.
Here is the .bat file:
@echo off
c:
cd "c:\Inetpub\ftproot\Debitin"
C:\Inetpub\ftproot\Logrecord\pullscript.txt echo open localhost

Not able to execute startEclipse.bat file in Eclipse (Oracle utilities SDK)

In Eclipse installation, i am not able to run "startEclipse.bat" file in this path "C:\SPLSDK\SDK\shortcuts" which comes under Oracle Utilities Software Development Kit 4.0.0.
once i start installing startEclipse.bat, i get a error message "windows cannot find /eclipse.exe, make sure you typed correctly and try again"
and how do i find the eclipse.exe on the installables? also in error message it shows backslash "/"eclipse.exe while executing "startEclipse.bat" file.
jdk and hibernate paths are located in "c:\spl". Is that fine?
And When I click “eclipse” in this path “C:\SPLSDK\SDK4.0.0.4\eclipse\eclipse-jee-galileo-SR2-win32\eclipse”, I get error "java runtime or jdk should be available in order to run eclipse. and no JVM was found after searching for the folder "C:\SPLSDK\SDK\4.0.0.4\_jvm\bin\javaw.exe" ". I have installed Jdk in “C:\spl\jdk1.6.0_18”. And to install Eclipse, should I change the path of installing jdk to support Eclipse installation?
what could be the reason?
Please give me suggession that how to install eclipse?

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.

.bat files and java program

I know that I have posted something just like this before, but I just can't get this to work. I want to have my application call a .bat file and execute it. Can anyone please supply me some code (maybe just a small program) that executes a .bat file from within the program itself. This would be very helpful. I just can't get it to work at all.

To open notepad in a windows system:
import java.io.*; // Needed for IOException
public class Notepad
public static void main(String[] args)
try
Runtime.getRuntime().exec("notepad");
catch (IOException ioExc)
System.out.println("Something has gone horribly wrong!");
Notes:
1) notepad is usually in the path system variable. You will probably have to type in the entire path to the .bat file you want to execute.
2) The .exec(programName) will block until the program is terminated.
3) You are losing any semblance of system independance by doing this.

Problems with calling a Bat file in java...

i'm having some issues when i try to call my bat file within java...
here is the code
Runtime.getRuntime().exec("cmd.exe C:\\dev\\CMIC\\components\\client\\bin\\startup.bat");
it starts up the bat file but it seems to only execute the first line in the bat, then it shuts it down... i dont get it. cuz if i call that bat from another bat it works fine.. if i click on it, it works fine why would java have a problem with it?

text-decoration: none;
h1{

They are working fine. However, it just does not execute the css file in the show_email_entry.jsp. Another word, the headerColumn should show some color as I coded it in the css file. But it shows only white background and black text. I have the file named DisplayData.css in the same directory as the file named show_email_entry.jsp. But it still does not work.
if I create a test.jsp and use with the DisplayData.css file above then it would work fine. But when I used it with the servlet file, then it would not work.
Anyone knows why ?
Thanks
