How to execute SAPgui.exe from java code

[Former Member]

Hi All,

Can any one provide me the exe file name of SAP GUI related.

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:
WINNT
system32
notepad.exe";

//Process pp=rt.exec("C:
j2sdk1.4.2_08
bin
javac");

Process pp=rt.exec("C:
Program Files
SAP
FrontEnd
SAPgui
SAPgui.exe");

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.

Its Urgent PLZ

Hi rajesh,

to laungh sapgui.exe end logon into a sap system you have to use this string:

String str= "C:\Programmi\SAP\FrontEnd\SAPgui\Sapgui.exe hostName systemNumber";

you can use also the complete connection string:

sapgui /H/<SAP router 1>[/S/<SAP router service 1>][...]/H/<host>/S/<service>

Or if you want only to launch saplogon.exe you can use

String str= "C:\Programmi\SAP\FrontEnd\SAPgui\saplogon.exe";

Hope this help

hi Rajesh,

here my complete code:

		try{
			Runtime rt=Runtime.getRuntime();
//			String str= "C:\Programmi\SAP\FrontEnd\SAPgui\saplogon.exe";
			String str= "C:\Programmi\SAP\FrontEnd\SAPgui\Sapgui.exe 10.113.10.201 00";
			//			Process pp=rt.exec("C:\j2sdk1.4.2_08\bin\javac");
			Process pp=rt.exec(str);
			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);
			}

	}

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

Hi Rajesh,

i'm not completely sure, but i don't think it's possible logon and call a transaction from command line.

In this thread there is a discussion on how to open the gui, logon and call a transaction from a web page...

Hope this help

Francesco

Happy new year!!!!!
