Launching External programs from an addon cause Client to stop

Hi.
We have an add-on that allow via configuration to launch other programs/files from SAP (Remote desktop, PDF-documents, etc.).
Launching other processes from an add-on is easy with the System.Diagnostics.Process.Start(file, arguments);
This has worked since SBO2004A, but since we began working with SBO2005A SP01 launching external programs cause the SAP Client to freeze every 5-10th time or so...
Nothing except stopping the add-on-process works.
When the add-on is terminated the Client "Wakes up" to inform that add-on has been disconnected.
Anyone else have had a similar problem?
<i>Kind Regards
Rasmus Wulff Jensen | http://www.b1up.net</i>

Regarding the thread, I whought about it, but since it is a process.Start, it a whole different process and threads should not have anything to do with it...
As always, yes I've created a message for this.... And got the normal response from SAP Support "We cant reproduce the issue... please send sample code"... sigh.... Hate random error that can't be reproduced... and sample code is hard to produce when you have created a whole framework above the SDK... I almost never do any "Core" SDK...

Calling an external program (*.exe file) on the client

Hi,
I use 9iDS and I'd like to call an external program (*.exe file) on the client, but this exe file is located on the server not on the client.
So it should be something like a mixture between host and client_host(webutil) command. Is it possible to use client_host where a virtual path is passed to?
Regards Sören

Are you saying you want to run on the exe on the client but its located on the server???
In that case you would have to do a webutil file transfer to move it to the client before executing. Or, if you are calling a DLL, webutil will download it automatically from the server to the client (see the C API example on the webutil page).

How to call Operating System commands / external programs from within APEX

Hi,
Can someone please suggest how to call Operating Systems commands / external programs from within APEX?
E.g. say I need to run a SQL script on a particular database. SQL script, database name, userid & password everything is available in a table in Oracle. I want to build a utility in APEX where by when I click a button APEX should run the following
c:\oracle\bin\sqlplusw.exe userud/password@database @script_name.sql
Any pointers will be greatly appreciated.
Thanks & Regards,

Hi Guys,
I have reviewed the option of using scheduler and javascript and they do satisfy my requirements PARTIALLY. Any calls to operating system commands through these features will be made on the server where APEX is installed.
However, here what I am looking at is to call operating systems programs on client machine. For example in my APEX application I have constructed the following strings of commands that needs to be run to execute a change request.
sqlplusw.exe user/password@database @script1.sql
sqlplusw.exe user/password@database @script2.sql
sqlplusw.exe user/password@database @script3.sql
sqlplusw.exe user/password@database @script4.sql
What I want is to have a button/link on the APEX screen along with these lines so that when I click that link/button this entire line of command gets executed in the same way it would get executed if I copy and paste this command in the command window of windows.
Believe me, if I am able to achieve what I intend to do, it is going to save a lot of our DBAs time and effort.
Any help will be greatly appreciated.
Thanks & Regards,

How can I execute an external program from within a button's event handler?

I am using Tomcat ApacheTomcat 6.0.16 with Netbeans 6.1 (with the latest JDK/J2EE)
I need to execute external programs from an event handler for a button on a JSF page (the program is compiled, and extremely fast compared both to plain java and especially stored procedures written in SQL).
I tried what I'd do in a standalone program (as shown in the appended code), but it didn't work. Instead I received text saying the program couldn't be found. This error message comes even if I try the Windows command "dir". I thought with 'dir' I'd at least get the contents of the current working directory. :-(
I can probably get by with cgi on Apache's httpd server (or, I understand tomcat supports cgi, but I have yet to get that to work either), but whatever I do I need to be able to do it from within the button's event handler. And if I resort to cgi, I must be able to maintain session jumping from one server to the other and back.
So, then, how can I do this?
Thanks
Ted
NB: The programs that I need to run do NOT take input from the user. Rather, my code in the web application processes user selections from selection controls, and a couple field controls, sanitizes the inoputs and places clean, safe data in a MySQL database, and then the external program I need to run gets safe data from the database, does some heavy duty number crunching, and puts the output data into the database. They are well insulated from mischeif.
NB: In the following array_function_test.pl was placed in the same folder as the web application's jsp pages, (and I'd tried WEB-INF - with the same result), and I DID see the file in the application's war file.
        try {
            java.lang.ProcessBuilder pn = new java.lang.ProcessBuilder("array_function_test.pl");
            //pn.directory(new java.io.File("K:\\work"));
            java.lang.Process pr = pn.start();
            java.io.BufferedInputStream bis = (java.io.BufferedInputStream)pr.getInputStream();
            String tmp = new String("");
            byte b[] = new byte[1000];
            int i = 0;
            while (i != -1) {
                bis.read(b);
                tmp += new String(b);
            getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + tmp);
        } catch (java.io.IOException ex) {
            getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + ex.getMessage());
        }

Hi Fonsi!
One way to execute an external program is to use the System Exec.vi. You find it in the functions pallet under Communication.

Running an External Program from Batch on Windows Server 2008R2 Failing

Hi,
I am trying to run an external program from a batch job and it is failing with this error message:
Ext. prog.: ERROR: Input redirection is not supported, exiting the process immediately.
Ext. prog.: External program terminated with exit code 1
The program I am trying to run is: timeout
This command works on the OS: timeout -t 30
I have setup the step to look like this:
Under External Program:
-Name: timeout
-Parameter: -t 30
I have also tried:
-Name: timeout -t -30
-Parameter:
I am running ECC 6.04 on top of Windows Server 2008R2 with SQL Server 2008R2.
When we were running in Server 2003 on ECC 6.0 I was able to use the Sleep program just fine in the same manner. I have found out that sleep is not available in server 2008. It was replaced with timeout.
After an update to EHP4 and moving to Windows Server 2008R2, Is there any pre-work that needs to be done on the SAP or Windows side before we can run external programs?
Thank you,
Neil

No - this is no more true like that since Windows 2008, it's a bit more complex:

Add the policy using group policy editor (gpedit.msc)

[Solved] Launching Graphical Programs From The Terminal

Occasionally I launch graphical programs from the terminal and they usually spit out what they're doing in the background, I know you can send this output to /dev/null but is there a way to have that is the default setting (ex. not having to type &> /dev/null each time) and then somehow turn console output back on when I want to debug something? I tried creating an alias but that didn't work.

Invoke External programs from inside App Server

hi,
How can I invoke an external program from a session bean (or from an MDB)?
Can I use Runtime.exec() directly from a bean?
If so, are there any security considerations?

Adobe Updater requires password when I launch any program from the suite

It is very annoying, but not a destructive issue.
When I launch any program from Creative Suite 3 Design Premium (6 programs) the Adobe Updater pops out and asks for a password. I can either provide a password and proceed, or deny the password and still proceed with the program.
Is there any way to stop the Updater from popping up?
I have it on my two machines Mac Pro (2x 2.66 GHz, 11GB RAM) and Mac Book Pro (2.33 GHz, 3GB RAM).
I am sure that there is some settings which I simply overlooked. Can anyone point it to me?
I would appreciate that. Thanks.
Jack

Unfortunately when Adobe products are restored from backup, especial CS4 and especially Mac, it breaks licensing.
There is a python script included in the license recovery kit that should work if you are familiar with Terminal.
If not, you must reinstall your CS4 suite. You don't need to delete your preferences, so it should be the same as before.

How to launch a program from Director?

Hi, I'm new to Director.
I want the user of my Director movie to click on a button
that launches Adobe Acrobat and a help file (external to the
Director movie).
How do I do this?

I have a similar question... can Director be used to launch a
program? I understand that you can tell it to open a file, in which
case the default application is automatically launched, but can you
give it a specific command line to execute?
I have SCALA MM200, and it can execute command lines from
within Windows, but as I recall it wasn't a very seamless
transition between the presentation and the launched program. I
hesitate to keep using MM200, since it was designed for Win 98/NT,
but rather than buy new software it might be best to stick with
what I've got if it still works under XP.
Seems to me a lot of current "multimedia" software is great
for animations and presentations, but there's little consideration
for creating a true GUI with it that will do stuff outside of the
presentation itself. I suppose I should go with VisualBasic or
something like that, but my programming days are 20 years behind
me, and there's still the issue of buying new software (unless VB
is free, which I doubt).
I plan to try MM200 under XP, but if it doesn't work, or
doesn't perform quite as I'd like it to, it would help to know that
Director could work. However, if there's no way to execute a
specific command line, it probably isn't the right choice for me.
A quick summary of my planned application is to present a
menu of choices to the user, and then execute certain programs
depending on the choice. The presentation will probably hide in the
background while these programs run, so another consideration is
avoiding any conflicts. The programs are video game emulators, and
certain options are set in the command line, so simply telling
Director to open a game file may not work, even if the emulator is
set as the default application to open that file. I'll still need
to pass certain command line switches to the app, and I'm not sure
I can do that in Director.
Thanks in advance for any help! :) (I never visit the forum,
so it's best to e-mail me at [email protected])

Can you Launch External Applications From Within InDesign Ebook?

Hi all,
I was wondering if it is possible to open an external application from within an ebook (created with InDesign) e.g. click on a link and have an external ssh client open up for instance?
Thanks in advance for any advice.
Regards,
RG

It's possible to include hyperlinks in an InDesign file and export them in an EPUB file. Since I'm not familiar with working with SSH clients (in fact, I just had to Google it to have a clue what you're talking about), is this something that can be invoked in a standard URL format? If so, you could probably include it.
The next issue is whether the link would work. The link couldn't be used directly in any eBook reader I know of, but at least the iBook on an iPad or iPhone would switch to to Safari to let you follow a URL to its destination. But I don't think that's possible on most eBooks.
