Is it possible to execute SAPGUI scripts from java program?

Hi everyone..
     I need to develop an java applications that executes the SAPGUI script or any technique that execute set of transaction as client.
     Is it possible to execute SAPGUI scripts from java program? if so, how it can be achieved? is there any other technique to achieve above mention scenario?.
     it will be more helpful, if docs related to that are shared..
     Thanks in advance

Oh, bummer. Would be much more convenient if I could just use iTunes for everything. Can't stand WMP. I wonder if WinAmp might be a good compromise?
Thanks for this answer . . .

How to execute system command from java program

Hi all,
I want to change directory path and then execute bash and other unix commands from a java program. When I execute them separately, it's working. Even in different try-catch block it's working but when I try to incorporate both of them in same try-catch block, I am not able to execute the commands. The change directory command works but it won't show me the effects of the bash and other commands.
Suggestions??

The code I am using is....
try
String str="cd D:\\Test";
Process p=Runtime.getRuntime().exec("cmd /c cd
"+str);your str string is already having cd in it but again you ar giving cd as part of this command also please check this,i will suggest you to remove cd from str
Process p1=Runtime.getRuntime().exec("cmd /c mkdir
"+str+"\\test_folder");you should say mkdir once you change your path,but here you are saying mkdir first and then cd D:\Test(this is because of str)..please check this
Process p2=Runtime.getRuntime().exec("cmd /c bash");
Process p3=Runtime.getRuntime().exec("cmd /c echo
himanshu>name.txt");
catch(IOException e)
System.err.println("Error on exec() method");
e.printStackTrace();

How to execute .msi files from java program

Hi friends,
i have written a java program which invokes and thereby execute any executable files like .exe and .bat.
So its working fine with .exe and .bat files, but it is not working with .msi files.......can you please help me how can i execute .msi files as well??
public class Executeexe {
     public static void main(String ar[])
          try
          Process p=null;
          Runtime rt=Runtime.getRuntime();
          p=rt.exec("D:\\mysql-essential-5.0.83-win32.msi");
          p.waitFor();
catch(Exception e)
}here is the program

Make sure that the command that's being exec'd works from the cmd line.
Then read this article and do what it says:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
Then if you still are having problems explain what "...it is not working with .msi files..." really means, and provide a [SSCCE Example program|http://mindprod.com/jgloss/sscce.html]

Execute Unix command from Java program running on windows

Hello,
I need to write a java program that fetches file count in a particular unix machine directory. But java program will be running on windows machine.
The program should execute unix list command and fetch the output of that command.
Can anyone help me on this?
Thanks.

Hi there,
I had a similiar problem, though years ago. It was to have a java program execute any other. Lately, I've had to have a java program running on a unix machine execute a shell script. Entirely two different scenarios. I'm not sure what you will need for your app, but look into this:
Java Native Interface for executing C/C++ code.
C/C++ Code for launching the program you need to run.
java.lang.Runtime(?).exec(....)
With a combination of that stuff, you can make a launcher for any os that has Java running on it, and with Runtime, you can exec() pretty near any sort of unix shell or app command you'd like.
Good luck.

Execute ConcurrentRequest from java program

In order to execute concurrent request from java program are this 3 lines enough :
1)ConcurrentRequest concurrentrequest = new ConcurrentRequest(oadbtransaction.getJdbcConnection());
2)int i = concurrentrequest.submitRequest("some value", " some value", "some value", null, false, vector);
3)oadbtransaction.commit();
*******************************8
I am asking because while executing ConcRequest from PL/SQL I have to call a functin : fnd_global.apps_initialize(user_id ,resp_id, app_id) prior to executing FND_REQUEST.SUBMIT_REQUEST.
Is there any equivalent in java for apps_initialize?
thanks in advance.

hi
u can call the FND_global using callable statement
DBTransaction txn = getDBTransaction();
CallableStatement cs =
txn.createCallableStatement("begin fnd_global.apps_initialize(:1, :2,:3);end;");
try
cs.setString(1, getOADBTransaction().getUserId() );
cs.setString(2, getOADBTransaction().responsibilityId());
cs.setString(3, getOADBTransaction().getApplicationID());
cs.execute();
cs.close();
catch (SQLException sqle)
try { cs.close } catch (Exception(e) {}
throw OAException.wrapperException(sqle);

}Help please.

Your code is probably good to run a program, that does not use terminal capabilities.
Program "top" is a little bit more complicated - you have to run it with a real terminal.
Try to run "xterm -e top". You can find an example how to run an external program
from java code in cnd/gdb module on http://cnd.netbeans.org
For example, take a look at openExternalProgramIOWindow() method on this page:
http://cnd.netbeans.org/source/browse/cnd/gdb/src/org/netbeans/modules/cnd/debugger/gdb/proxy/Attic/GdbProxyCL.java?rev=1.1.2.6.2.5&only_with_tag=release551_fixes&view=markup
It runs a command with external terminal.
Thanks,

Problem while running dos command from java program

Dear friends,
I need to terminate a running jar file from my java program which is running in the windows os.
For that i have an dos command to find process id of java program and kill by using tskill command.
Command to find process id is,
wmic /output:ProcessList.txt process where "name='java.exe'" get commandline,processid
This command gives the ProcessList.txt file and it contains the processid. I have to read this file to find the processid.
when i execute this command in dos prompt, it gives the processid in the ProcessList.txt file. But when i execute the same command in java program it keeps running mode only.
Code to run this command is,
public class KillProcess {
     public static void main(String args[]) {
          KillProcess kProcess = new KillProcess();
          kProcess.getRunningProcess();
          kProcess = new KillProcess();
          kProcess.readProcessFile();
     public void getRunningProcess() {
          String cmd = "wmic /output:ProcessList.txt process where \"name='java.exe'\" get commandline,processid";
          try {
               Runtime run = Runtime.getRuntime();
               Process process = run.exec(cmd);
               int i = process.waitFor();
               String s = null;
               if(i==0) {
                    BufferedReader stdInput = new BufferedReader(new
                           InputStreamReader(process.getInputStream()));
                    while ((s = stdInput.readLine()) != null) {
                     System.out.println("--> "+s);
               } else {
                    BufferedReader stdError = new BufferedReader(new
                           InputStreamReader(process.getErrorStream()));

          return pixieLoc;
}     when i remove the process.waitFor(), then while reading the ProcessList.txt file, it says "No such file".
if i give process.waitFor(), then it's in running mode and program is not completed.
Colud anyone please tell me how to handle this situation?
or Is there anyother way to kill the one running process in windows from java program?
Thanks in advance,

Hi masijade,
The modified code is,
class StreamGobbler extends Thread
    InputStream is;
    String type;
    StreamGobbler(InputStream is, String type)
        this.is = is;
        this.type = type;
    public void run()
        try
            InputStreamReader isr = new InputStreamReader(is, "UTF-16");
            BufferedReader br = new BufferedReader(isr);
            String line=null;
            while ( (line = br.readLine()) != null)
                System.out.println(type + ">" + line);
            } catch (IOException ioe)
                ioe.printStackTrace();

            } else {

                StreamGobbler(proc.getInputStream(), "OUTPUT");
                      // kick them off
            errorGobbler.start();
            outputGobbler.start();
            // any error???
            int exitVal = proc.waitFor();
            System.out.println("ExitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}when i execute the above code, i got output as,
Execing cmd.exe /C wmic process where "name='java.exe'" get commandline,processid
and keeps in running mode only.
If i execute the same command in dos prompt,
CommandLine
ProcessId
java -classpath ./../lib/StartApp.jar;./../lib; com.abc.middle.startapp.StartAPP 2468
If i modify the command as,
cmd.exe /C wmic process where "name='java.exe'" get commandline,processid > 123.txt
and keeps in running mode only.
If i open the file when program in running mode, no contents in that file.
If i terminte the program and if i open the file, then i find the processid in that file.
Can you help me to solve this issue?

How to call 'WordPad' from java program........

The following code will open 'Notepad'
Runtime runt = Runtime.getRuntime();
Process pr = runt.exec( "notepad" );likewise, I want to open 'Wordpad'
Runtime runt = Runtime.getRuntime();
Process pr = runt.exec( "wordpad" );The above two line code, compiles successfully, but it doesn't give the correct result.
If I give 'wordpad' in start->run->'wordpad', in windowXP means, the Runtime executer opens 'WordPad',
can anyone give the solution to open WordPad from Java Programming.
thanks
Sarwan_Gres

Try this:
Runtime runt = Runtime.getRuntime();
Process pr = runt.exec("cmd /c start wordpad");
