Calling external scripts from Process Flow

Hi,
I'm trying to pass a list of parameters to a unix shell script using the parameter list in the process flow external process activity. However the parameter list is not being correctly passed. What is the correct format, delimiter & use of quotes ?
Examples:
Parameter List : REPORT_GROUPS,IGA,QLD,1
Unix receives : EPO T_G OUPS,IGA,QLD,1 (3 parameters)
and
Parameter List : REPORT_GROUPS IGA QLD 1
Unix receives : REPORT_GROUPS "" IGA "" QLD "" 1 (7 parameters - "" = null parameters received)
Quotes just seem to be ignored.
Can anyone give me the correct format or the where the format is documented ?
In using OWB 9.0.4 with Oracle 9.2.0.2 on a HP UX server.

Hi Pavel,
The process flow editor interprets the first character in the parameter list as a separator (the 'R' in 'REPORT_GROUPS...' in your case).
Check out OWB User Guide chapter 9, which says :
Parameter List The list of parameters to be passed to the external process. Type the path
and file name such as ?/c?c:\\temp\\run.bat .
The Process Flow Editor interprets the first character you type to be the
separator. For example, the Process Flow Editor interprets the following
entry as /c and dir.
?/c?dir?
Use the backslash as the escape character. For example, the Process Flow
Editor interprets the following entry as -l and -s and /.
/-l/-s/\//
Hope this help.
Regards
Rolf

Calling .exe file from process flow

Hi All,
I want to call an executable file from my process flow. What should I do for this. Please tell me. Eg. I want to call RUN.exe located in "c:\myfolder\run.exe" what should I do?
Please help.
Thanks,
Danish

I have had trouble with the user defined operator.
Instead I use SQLPLUS operator to do these types of things.
Use this for the Script Value:
host c:\myfolder\run.exe
exit;

Calling external programs from within a Tomcat application

I've got a fairly complex existing Tomcat application (which is packaged and built as a .war file) which I'm trying to edit so that it calls a Perl script part way through the processing, which will generate an XML file used later on. I think I've worked out how to call external scripts from within Java, but at the moment when I try and access the application via Tomcat the application either hangs or bails out (I don't know which, as the log files unhelpfully don't give any error messages).
The code which is causing the problem looks like this:
System.err.println("Calling runtime...");
Runtime runtime = Runtime.getRuntime();
System.err.println("Executing process...");
Process process = runtime.exec("/path/to/ysearch.pl 'News' '\"search query\"' 'file");
System.err.println("Waiting for process...");
int exitVal = process.waitFor();
System.out.println("Exited with error code: " + exitVal);The code gets as far as "Executing process..", beyond that there is nothing in the log file so I presume the runtime.exec() call is where the problem is. I'm not interested in reading the output from the script (there shouldn't be any), so that's not an issue, and the permissions on it allow anyone to read or execute ysearch.pl so I don't think there's a problem in that area.
Does anyone have any suggestions which I could try to get this to work? I've only been using Tomcat for a week (I'm picking up on someone else's code) so I might have made a beginner's mistake. I'm using Tomcat 5 on Fedora Core 7, and Java 1.5.0_01 (I can't easily change any of those).

I'm not sure, but I thing that overhead caused by calling du cannot be big enough to matter even on older machines.
But, when calling du from Perl script you are also invoking shell, and this can be a little bit more 'heavy'.

Calling SAP scripts from WEBDYNPRO

Hi
We need to call SAP scripts from WebDynpro application. As per my understanding we need to do following steps
Create a new RFC function module and create sap script output in PDF format.For this
    - use OPEN_FORM , by assigning TDGETOTF='X' in the Options(Structure
      ITCPO).
    - call function module CLOSE_FORM with option OTFDATA
    - convert OTF data to PDF by using function module CONVERT_OTF_2_PDF
Now I would like to know how to display the PDF string from WebDynpro.
Please help....

Hi,
You can call by creating external window method.
create LINK to URL or LINK TO ACTION according to requirement, for this. write code in onaction of that.
data: iv_url type string value 'http://<server>:<port>/sap/bc/gui/sap/its/webgui?~transaction=*se38 RS38M-PROGRAMM=rsparam;DYNP_OKCODE=SHOP'.
data: api_component type ref to if_wd_component,
          window_manager type ref to if_wd_window_manager,
          window type ref to if_wd_window.
api_component = wd_comp_controller->wd_get_api( ).
window_manager = api_component->get_window_manager( ).
window = window_manager->create_external_window(
                 url = iv_url
                 modal = abap_false ).
window->open( ).
Cheers,

Calling shell script from apex application

Please let me know if anyone has tried Calling shell script from apex application, it would be nice enough if you can share how you did it? Thanks

Hi,
Requirements
* CREATE JOB (10g Rel.1)
* CREATE EXTERNAL JOB (10g Rel.2 / 11g)
* EXECUTE on dbms_scheduler (granted to public by default)
Since Oracle 10.2.0.2 the commands are executed as user nobody.
Code:
--Create a Program for dbms_scheduler
exec DBMS_SCHEDULER.create_program('RDS2008','EXECUTABLE','c:\ WINDOWS\system32\cmd.exe /c echo 0wned >> c:\rds3.txt',0,TRUE);
--Create, execute and delete a Job for dbms_scheduler
exec DBMS_SCHEDULER.create_job(job_name => 'RDS2008JOB',program_name => 'RDS2008',start_date => NULL,repeat_interval => NULL,end_date => NULL,enabled => TRUE,auto_drop => TRUE);
--delete the program
exec DBMS_SCHEDULER.drop_program(PROGRAM_NAME => 'RDS2008');
--Purge the logfile for dbms_scheduler
exec DBMS_SCHEDULER.PURGE_LOG;
This is one way as suggested by Trent.
We can also achieve as follows.

Calling ASP script from APEX button passing Bind variable

I am looking for some examples or best form for calling asp script from apex button that will pass apex bind variable to asp script to process.
Thanks,s
Bob

I am surprised by the degree of no replies. I have solved this by using asp redirects such as:
Response.Redirect("test.aspx?UserName="&user)
My formulated solution contains a page with a manually built interactive report. I have a number of bind variables at the top of the reoprt where users can query the information they want based on desginated database columns for this particular report. Once they have the "manual" interactive report displaying what they want, they click a button where a asp script is called with parameters passed that calls a Java based Crystal Reports plugin with the called correspnding report displayed with passed parameters.
Works like a charm!
This solves our reporting needs without having to resort to Bi Publisher (much too expensive) and other third party applications that kinda indicate it can work with apex but provide limited help or best form for doing so.

Calling external programs from Java?

Hi All,
Is there a way of calling external applications from Java without using Runtime.exec(). That method seems quite messy when you are dealing with streaming data from an input file to an output file. Basically what I'm asking is there a way to run a command the same way you would type it in a command shell?
Thanks

LeWalrus wrote:
Ok, I've an external application that I want to be called inside a Java GUI. It has several input arguements, which the format looks something like:
programname inputfile > outputfile
Simple enough.

Works fine from a shell command line. From what I understand, this won't work using Runtime.exec() because that method will just start the application. Works fine from Runtime.exec(). Since you are'>' to write stdout to a file you need to us a shell to execute the command.
String[] command = {"sh", "-c","programname inputfile > outputfile"};
Process process = runtime.exec(command);
You need to read, digest and implement the recommendations given in http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html .
File input and output from the application has to be taken care of programatically (java.io stuff). Fine if you've only one input and output. But if you have several input files and hundreds of output files, where does this leave you. It would be much easier if you could pass a string command to the shell directly as if you typed it in the command line yoursel!

Call PERL script from JAVA

I am facing a problem in running a PERL script in JAVA in UNIX box..
I am able to call ther perlscript.
Perl script has
#! /usr/local/bin/perl
print "\nEnter Your Name :";
$name = <>;
print "\nYour Name is : $name\n";
exit 0;
Perl script request for the INPUT(name) .
My Java program is
File perlfile = new File("test.pl");
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("perl "+perlfile);
Here is the problem tat IT IS says error =2 ..What has to be the solution so tat i can CALL PERL SCRIPT as similiar to running it separatly in prompt { >perl test.pl }
PLEASE help me on this....

In the PERL SCRIPT (test.pl)
LINE 1 : #! /usr/local/bin/perl
LINE 2 : print "\nEnter Your Name :"; .
LINE 3 : $name = <>;
LINE 4 : print "\nYour Name is : $name\n";
LINE 5 : exit 0;
When i run this script in perl test.pl in prompt (UNIX BOX), i am gettin the request for name "Enter Your Name:____ " but when i call this script from Java it doesn't request for name and moreover the process doesnt ends (use ctrl+c to come out of the process).When i come out forcefully it shows the ERROR=2.
My requirement is such tat need to call a PERL SCRIPT from java so tat java process give the control to PERL script and it will continue the process..
Sample scenario:
Java move a file and store it in a new FOLDER
MY perl script will read the file in new FOLDER.
here the perl script will get the file name for processing... My issue comes here .$name is not be prompted while calling thro java..

Calling GUI Scripting from ABAP program

Is it possible to call GUI Scripting from ABAP and thus to use GUI Scripting as an alternative to CALL TRANSACTION?
Is the class CL_JAVA_SCRIPT suitable to access GUI Scripting engine? Accessing ABAP data object would work as well in this case as i think. What SAP Logon and WAS releases are required? Is the 6.20 release sufficient for this case?
I would appreciate if somebody could post an example.

Hi,
CL_JAVA_SCRIPT has nothing to do with SAPGUI Scripting.
Calling SAPGUI Scripting API from ABAP could be possible for programmes experienced with OLE automation calls from ABAP coding.
The hardest thing will be, to access the scripting engine handle as an entry point. Once you have a handle in your abap session, any api function can be invoked.
Best regards
Jens
BTW: SAP testtool eCATT does call SAPGUI-Scripting from ABAP.

Calling Ant script from Jdeveloper

Hello Gurus,
I am trying to call Ant script from Jdeveloper.
I am able to call it when i don't use any javac in ant script.
But as soon as i include a javac command

I get below error
C:\ant\windows\svn\AntJava\Project1\build.xml:20: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.

Needless to say i already have implemented all the steps mentioned in the internet.
I have my JAVA_HOME correctly set in my PATH environment variable.
I have tools.jar in the CLASSPATH
Please give a solution from JDeveloper perspective and not a generic one as i am done with all the steps provided in internet.

Calling PERL script from scheduler

Hello All,
I am trying to call PERL script from dbms_scheduler which makes the database connection using DBD module to read some values to perform the operation. My scheduler job kept failing with the following error:
ORA-27369: job of type EXECUTABLE failed with exit code: No such file or directory
STANDARD_ERROR="install_driver(Oracle) failed: Can't load '/usr/lib/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.10.1: cannot open shared object file
It can't open libclntsh.so.10.1 file when I run the job, I guess because in job session, it creates a new shell and doesn't inherit the .profile and none of the environmental variables get set. When I run the PERL script manually it works because of all the env variables, so I put all those variables from my .profile into PERL script itself using ENV function but it still doesn't work, failed with very same error. And yes I do set LD_LIBRARY_PATH to point to $ORACLE_HOME/lib directory. Moreover, if I run the PERL script manually from a shell where I dont inherit .profile, it fails with very same error, so it is related to the environment issues but I have no idea how to fix it. I read somewhere the setting those env variable in PERL script itself doesn't help because by the time PERL get executed all the compilers are already initialized and and they don't use those environement variables anymore then. So the question is how to make it work?
I would really appreciate if someone can help me fixing this, it's gonna change my life here :)
DB Version: 10.2.0.2 (also tested on 11R2, same problem)
OS: SUSE Linux 64 bit
