CL_GUI_FRONTEND_SERVICES => EXECUTE doesn't execute a command.

Hello!

Yesterday when using CL_GUI_FRONTEND_SERVICES => EXECUTE method I ran into a weird problem. The problem is that I cannot correctly run a .bat batch file that is located in a client computer. I created a .bat file with few input parameters and when running it from my Windows computer then everything works spectacularly but when I try to run this using EXECUTE then it just doesn't run correctly. For testing purposes I hardcoded these parameters into the batch file and when running from Windows it runs a java utility. (The reason why I don't use EXECUTE to run the java utility directly is that the parameter string to this utility is more than 255 characters long but most of the parameter string is just static information and really only 20 characters change every run and that's why I created a .bat file). The problem is that when I execute this batch file from SAP then a file has to be created as a result and then I upload this file to server. When running locally this file is created correctly without any hassle but when calling it from SAP then it calls this java utility at client computer but it stops at some place and doesn't create the required file. This utility wasn't created by me so I cannot locate the place where it stops.

The code I use to execute the .bat file is:

CONCATENATE '"' xml_dl_path '" ' PIN2 INTO sign_params RESPECTING BLANKS.

CALL METHOD CL_GUI_FRONTEND_SERVICES=>EXECUTE

EXPORTING

application = 'launch.bat'

default_directory = 'C:\Tools\jdigidoc\'

parameter = sign_params

synchronous = 'X'

minimized = 'X'

EXCEPTIONS

cntl_error = 1

error_no_gui = 2

bad_parameter = 3

file_not_found = 4

path_not_found = 5

file_extension_unknown = 6

error_execute_failed = 7

synchronous_failed = 8

not_supported_by_gui = 9

OTHERS = 10.

Could it be that there are some weird authorization loopholes I have to jump thorugh before I can successfully run this bat file?

Hello,

Have you tried with examples in note 77075?

Thanks.

Yes I did that and nothing changed.

That would be very useful note but this function is obsolete and as I stated in the question I don't even use it so I don't really see the importance of this note.

Do you have check about variable environment ? example : the path of the executable prog, the directory ...

Do you have created a log file to store some important value of the script .. ?

As I said the execute command executes the .bat script. But it doesn't finish correctly. It searches for some dll files from the system and after that it stops working. Those dll files are essential to the java utility I'm acttivating from the batch script. When I run the same script from the client computer directly then it finds the dll files and runs as it should.

I'm not a Microsoft addict, but, when you create a batch, at first you have to define the environment variable. Because when you connect to a computer the system give you a set of variable. I'm not sure you have the same variable when you use the SAP method.

try to open a commande prompt, and launch the "set" command, you will understand

The thing is that this batch file finds the environment variable. When the java utility starts looking the dll then this thing pops up into the cmd screen:

JDigiDoc - 3.7.2.652

Reading config file: jdigidoc-pkcs11.cfg

Creating digidoc: DIGIDOC-XML / 1.3
