How to call a shell script in Java ?

Hi there,
i try to call a shell script in java but it wont work.
please can anybody help me.
my Code :
import java.io.*;
public class SendMessage{
Runtime rt;
public SendMessage(){
rt = Runtime.getRuntime();
public void send(){
try{
rt.exec("sendMessage.sh");
System.out.println("Message was Send");
catch(IOException ex)
ex.printStackTrace();
the file called sendMessage.sh is also stored in the same directory as the class File.
the exception never cames up but the script also never starts.
what is wrong ??? :-((
need help !
}

rt.exec("sendMessage.sh");Oh, sorry, I didn't see that you tried under UNIX.
BTW you should check for the OS - this stuff is very os and os release dependent.
I have not experimented with this under unix.
But something must interpret that sendMessage.sh file.
Perhaps the hash bang info is used by exec() (did you put a
#!/bin/sh as first line in your .sh file?
If not, try
rt.exec("/bin/sh sendMessage.sh");Regards,
Marc

How to call shell scripts

Hi,
Please let me know how to call shell scripts from WDA
Thanks
Bala Duvvuri

Hi Bala
You can not call any client side funcitons using Web Dynpro ABAP, it is possible in BSP using JavaScript.
You can use Suspend and Resume Plugs to navigate to a BSP page and perform the shell script and return to WDA using Resume Plug.

Invoking a bash shell script from Java code

Hi All
I am trying to invoke a Bash shell script using java code. The arguments required are "source wmGenPatch <source dir> <destination dir> no_reverse.
in the code I have specified the arguments considering the cannonical paths of the files as the code may run on Unix or windows platform.
I am getting a error while invoking Runtime.getRuntime().exec(args). The error is as follows :
"The Error Occurred is: CreateProcess: source D:\Package4.0\workspace\DiffEngineScripts\v4a02\wmGenPatch D:\Package4.0\workspace\fromImageFilesDir\ D:\Package4.0\workspace\toImageFilesDir\ no_reverse error=2"
It seems that error=2 indicates that the 'file not found' exception. But i can see the directories referred to in the error at place in the workspace.
Kindly advice.
Thanks in advance.

Hi All
I am pretty new to invoking bash shell scripts from java and not sure if i am progressing in right direction.
The piece of code tried by me is as follows
try {
               currentDir = f.getCanonicalPath();
          } catch (IOException e) {
          if (currentDir.contains("/")) {
               separator = "/";
          } else {
               separator = "\\";
          String args[] = new String[7];
          args[0] = "/bin/sh";
          args[1] = "-c";
          args[2] = "source";
          args[3] = currentDir + separator + "DiffEngineScripts" + separator
                    + "v4a02" + separator + "wmGenPatch";
          args[4] = sourceFileAdd;
          args[5] = destFileAdd;
          if (isReverseDeltaRequired) {
               args[6] = "reverse";
          } else {
               args[6] = "no_reverse";
          try {
               Process xyz = Runtime.getRuntime().exec(args);
               InputStream result = xyz.getInputStream();
               InputStreamReader isr = new InputStreamReader(result);
               BufferedReader br = new BufferedReader(isr);
               String line = null;
               while ( (line = br.readLine()) != null)
                    System.out.println(line);
               int exitVal = xyz.waitFor();
               System.out.println("Leaving Testrun.java");
          } catch (Throwable t) {
               t.printStackTrace();
and on running the same i am getting Java.io.IOException with the stack trace
java.io.IOException: CreateProcess: \bin\sh -c source D:\Package4.0\workspace\DiffEngineScripts\v4a02\wmGenPatch D:\Package4.0\workspace\fromImageFilesDir\ D:\Package4.0\workspace\toImageFilesDir\ no_reverse error=3
kindly advice
Thanks in advance

How to run unix shell script from java web applet

hi all
i have created one java applet. my apache web server is on unix server.
i have created one shell script in same directory where my .class and .htm files reside...
how to run this shell script from applet? it should search this .sh file on server and not on the client browser machine...

I suppose you could make the shell script into a CGI, configure the server to execute CGIs, and then make the applet open the URL of that CGI.

But my code is something look like thisWell unless I've completely lost my marbles (possible) or Java Runtime.exec() does something I've never heard of, I can't even see how that will execute. For a start, assignments in the Bourne shell take the form ofinfile = $inputFilename;orinfile = "inputFilename";not what you've got; and the first form would only work if you've set the appropriate environment variables.
Are you sure you're not confusing this with a Javascript script?

And BTW, you don't need to put ';' at the end of each statement, unless there's more than one on a line.
Edited by: YoungWinston on Apr 18, 2011 12:54 PM
BTW2: 'printf "%d", inpath' also looks very dodgy, since 'inpath' is unlikely to be a number (in fact, it's unlikely to be anything).
I think you might want to get a book on scripting.

Pass in date from shell script to java program

Hi,
I need to pass in some parameter to my java program.
eg 'java SomeProgram yyyy mm dd hh mm ss'
How do i use the shell script to generate the valeus for the year, mth day etc?
The program is running once everyday.
I tried $argu0 = `date+%y`
java SomeProgram $argu0
but not working... thanks for your help!

Then, why would you want to use 'date' to provide
'now' to a Java program when you could just use new
java.util.Date() which probably makes the same call
as the Unix 'date' command?That works until you need to use a date other than 'now.'
    public static final String ISO_DATE = "yyyy-MM-dd HH:mm:ss";
    public static void main(String[] args) {
        SimpleDateFormat sdf = (SimpleDateFormat) SimpleDateFormat
                .getDateTimeInstance();
        sdf.applyPattern(ISO_DATE);
        try {
            Date d = sdf.parse(args[0]);
            // rest of code here
        } catch (ParseException e) {
            // handle exception
    }Users will have to enclose there input with quotes otherwise the JVM will consider their input as two parameters, or you can change the pattern to include a character between dd and HH.
