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 execute Unix script from java?

Can I execute Unix script from java?

Yes. Using ProcessBuilder. And read [When Runtime.exec() wont|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html]. It's old, but pretty much all of it is still true.

hi
how can i execute any batch files or any other exe files (vb scripts) from java programs

Hi,
You use Runtime.exec to execute commands / exe-files. See the documentation (and remember that it will only work on windows):

How to execute SAPGUI script from the command line?

I have created a script and would like to execute it from the command line. There must be some flag that goes with SAPGUI.EXE. Any help appreciated.
Thanks,
Jeff

Hi Jeff,
the best way to do this is to run the script using the Windows Script Host, for example like this:
cscript myscript.vbs
This will execute the script which in turn can access SAP GUI. You may however have to make sure the script attaches to the correct session.
Best regards,

Executing unix scripts from java...

Hi guys,
I'm pretty new at this java stuff, but can someone tell me if it's possible to have a java object that connects to a specific unix box through a given IP and Port and execute a Unix shell command? The shell script creates a file that will be later ftp'ed from the UX box back to the PC I ran the java program from. Any ideas?
Thanks in advance.

Yes I thank it can be done. I have not done it but you prob can do it through tcp/ip useing ServerSocket and socket class.Make a server with the ServerSocket class on the linux box that is listening to the port and when it gets the right signal from your client on your pc/win the server will activate the sell script with the Runtime.getRuntime().exec(shellscript);
Well just a thought GOOD LUCK

Error while trying to execute a unix shell script from java program

Hi
I have written a program to execute a unix shell script in a remote machine. I am using J2ssh libraries to estabilish the session connection with the remote box.The program is successfully able to connect and authenticate with the box.
The runtime .exec() is been implemented to execute the shell script.I have given below the code snippet.
try {
     File file_location = new File("/usr/bin/");
     String file_location1 = "/opt/app/Hyperion/scripts/daily";
     String a_mib_name = "test.sh";
     String cmd[] = new String[] {"/usr/bin/bash", file_location1, a_mib_name};
     Runtime rtime = Runtime.getRuntime();
     Process p = rtime.exec(cmd, null, file_location);
System.out.println( "Connected to the server1" );
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = br.readLine();
while(line !=null)
System.out.println(line);
line = br.readLine();
br.close();
p.getErrorStream ().close ();
p.getOutputStream().close();
int retVal = p.waitFor();
System.out.println("wait " + retVal);
//session.executeCommand("ls");
catch (IOException ex) {
I get an error message
Connected to the server

Hi, I am using a simple program to connect to a RMI server and execute shell script. I use the Runtime.exec aommand to do the same.
The script is sh /tmp/pub/alka/test.sh /tmp/pub/alka/abc/xyz/ul ul
The script when run from the server, gives no errors. But when ran using rthe above method in java, gives errors as follows,
Mycode:
String command = "/bin/sh /tmp/pub/alka/test.sh /tmp/pub/alka/abc/xyz/ul ul";
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec(command);

Error while executing unix shell script from java program

Hi All,
I am trying to execute unix shell script from a java program using Runtime.execute() method by passing script name and additional arguments.
Code snippet :
Java Class :
try{
     String fileName ="test.ksh";
     String argValue ="satish"; // value passed to the script
     String exeParam = "/usr/bin/ksh "+fileName+" "+argValue;
     Process proc = Runtime.getRuntime().exec(exeParam);
     int exitValue = proc.waitFor();
     sop("Exit Value is : "+exitValue);
catch(Exception e)
e.printStackTrace();
}Test.ksh
export -- application realated paths..
nohup abc.exe 1> test.log 2>&1;
$1
exit.By running the above java class , i am getting exit Value: 139 and log file test.log of 0 bytes.
when i am running the same command (/usr/bin/ksh test.ksh satish) manually, it's calling abc.exe file successfully
and able generate the logs properly.
Pls let us know where exactly i am stuck..
Thanks in advance,
Regards,
Satish

Hi Sabre,
As per the guidelines provided by the article, i had done below changes..
InputStream is = null;
InputStreamReader iStreamReader = null;
BufferedReader bReader = null;
String line = null;
try{
String fileName ="test.ksh";
String argValue ="satish"; // value passed to the script
String exeParam = "/usr/bin/ksh "+fileName+" "+argValue;
Process proc = Runtime.getRuntime().exec(exeParam);
is = proc.getErrorStream();
iStreamReader = new InputStreamReader(is);
bReader = new BufferedReader(iStreamReader);
System.out.println("<ERROR>");
while((line = bReader.readLine()) != null)
System.out.println("Error is : "+line);
System.out.println("</ERROR>");
int exitValue = proc.waitFor();
sop("Exit Value is : "+exitValue);
catch(Exception e)
e.printStackTrace();
Now , it's showing something like..
<ERROR>
</ERROR>

Problem executing Unix script from Java...

Hi there, I'm having trouble executing a unix script from a java program. The script receives multiple parameters and it seems that one of them ( or more ) is not well interpreted. When I run the script directly from a shell, the script executes without any errors. But, when I run the exact same script with the exact same parameters, it does not work.
Here is the command to execute the script with all the parameters that is executed from the shell ( with success ) and also from the java program ( with errors ):
/z/opus/dcap/intfu001.csh 'NODEBUG^NOTKPROF^NOSTACK' opus dcap JACQUES JACQUES '2625781' 'ORA$PIPE$001D00D70001' JOB^DEBUG^SINISIMU^STATPROD^DECTIDANC^81^503^4080^86^87^151^97^98^99 BUT^N^N^SPRI^0^13^24^3^J^05^N^19^19^19 >> /tmp/switcher8.999.null.pgm.test
And here is my portion of code that executes the script:
Runtime wShell = Runtime.getRuntime();
Process wProc = wShell.exec(cmd_unix_final);
wProc.waitFor();
return wProc.exitValue();
Please give me your thoughts on this!
Thanks in advance!

Ok.
Let's proceed surgically, else we'll never solve or overcome anything.
In the last your reply you wrote:
the normal output is what I get when the script runs successfully, the script first prints a few things
and then does stuff that takes at least 2 or 3 secondsWhat do you mean?
-Finally have you got your script correctly executed?
The stuffs you spoke of are really performed?
If this is the case I can't see the prob.
Is your concern only about exitValue() for it doesn't let you distinguish programmatically
the success or failure of the script execution?
Of course you surely already have a routine in your java code to handle
exceptional situations of errors from the script.
And the "normal output" is just what you must parse to detect those errors.
Then who cares about exitValue() in this case?
Don't invoke it, relay on the stdout and stderr of the script.
-Or you get only a deceiving standard output
that let you think the script execution went alright, while instead it didn't.
In this case we have to investigate some other thing.
I can't still exclude that the problem isn't related with the buffer size of the stdout
allocated by the environment to the subprocess. You spoke of few things printed out.
Be explicit. What's the size of the output you get?
And is the "normal output" complete till the very last char
or is it truncated from somewhere on?
Also it's important that you hit a ps command after the java main process terminates
(or simply when waitFor() returns) and see if the script subprocess hung up.
As an alternative approach directly call your pro*C code from Java through JNI, instead of translating it.
1. Exec.java
public class Exec{
     static{
          System.loadLibrary("Exec");
     public static native void proCFunct();

I need to call the SAP GUI related exe file from java.
i tried with a small java prog which executes the exe files.
it works fine with notepad.exe,javac.exe . But i am unable to execute the SAPgui.exe.
This is my java code
try{
     Runtime rt=Runtime.getRuntime();
//String str= "C:

BufferedReader br=new BufferedReader(new InputStreamReader(pp.getErrorStream()));
                     String line;
                     while ((line = br.readLine()) != null) {
                         System.out.println(line);
          }catch(Exception e){
               System.out.println(e);
and may i pass any additional parameters inorder to invoke this exe.
Please share your ideas abt this problem.

hi Rajesh,
here my complete code:

//               String str= "C:\Programmi\SAP\FrontEnd\SAPgui\saplogon.exe";
               String str= "C:\Programmi\SAP\FrontEnd\SAPgui\Sapgui.exe 10.113.10.201 00";

               }catch(Exception e){
               System.out.println(e);
Please note that system number is only two digit and in your case is 00.
Another important think, i'm using the italian version of windows, so the program directory is c:\programmi, please change into c:\program files, or you can modify your code to be language indipendend using an system environment variable (if exist).
Hope this help

Is it Possible to Run SQL Script from Java prog

Hello
Is there any API by which we can run SQl Script file ,
Just by giving database configration parameters and SQL Script file Path ,it will execute that script automatically

You can excute SQL statemetns throught JDBC, but that doesn't have a facility to read those statements from a file. You'd have to write code to read the file and create and execute statements through JDBC. That should be pretty straightforward though.
It's conceivable that there's a third party library out there that does it, if you know what to look for.
If you're not familiar with JDBC, check out http://java.sun.com/developer/onlineTraining/Database/JDBC20Intro/

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.

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:

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]
