DAC External Program

When launching an external bath file task the task hangs. Is there a command that needs to be run to communicate back to the DAC server that the batch file is complete? If so what is it? I haven't found anything in the command line references that would suggest a command to do so.

You need Runtime.exec() and you can save yourself a lot of grief and time by reading http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html.
Once you have read it, read it twice more!

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.

System exec, How I say to open one file and make operation in external program?

Hi,
I got called an external program with the system exec.vi, but i would like the program open the file saved in the other window, i can get the file path, but how Can I put the file path in the external program and the program open the file and I tell (in this case compile), since i open one file code c and only i must to open and say to the program 'compile' and then close external program.
Any help?. Thanks.

Hi Fonsi,
System Exec.vi will allow you to run commands like launching a program easily but it is difficult and many times not possible to execute commands within an application.
A better way maybe to approach this though ActiveX. Please look at the following example that uses ActiveX to communicate with Excel.
Writing Rows to Excel 97 and Excel 2000 Using ActiveX
If you are not familiar to ActiveX and LabVIEW, please read the document below:

I hope this
helps.

How can I display files in external program like Word?

Using NetBeans 6.5, IE7, Windows XP
I have not had any luck attempting to get a PDF file to display in a separate browser window,
so I thought I might try to combine that with a new issue.
I have 3 file types - jpg, rtf and pdf that should be able to be displayed in external programs like Word or Adobe.
Is there a way to start an external application and pass the file name from a backing bean?
The files would be located on the server in a directory that is mapped to the client and the applications (Word, etc.) would reside on the client.
Can this be done from within the confines of a JSF application?
Thanks

I was kind of hoping that someone could point me to an example of how to do this.
I've tried the servlet approach, but can't seem to get the file to display in a separate browser window.
That is why I thought about maybe launching a separate application, if that is possible.

How can an add-on like Firesheep access and execute an external program like Winpcap? Is that a security flaw in Firefox?

I have been reading about the Firesheep add-on that allows the user to hijack sessions of users on the network by stealing the cookie. I understand that to prevent any application from stealing the cookie, the cookie should not be passed by the site without SSL. However, my understanding of how Firesheep works is that it interfaces with Winpcap (a network sniffer). So my question is "How can an add-on execute an external program or operating system command like Winpcap?" Can any add-on do this and should I be extremely afraid of downloading any add-on because of the potential that it could have complete access to my system?

Hi Scott-L.
You asked a very good question and it turns out you're right.
However, one must be aware that download an Addon on another website that Mozilla may be dangerous. Indeed, the Addons found on the Addon Center are checked (roughly).
In addition, Firefox includes a blacklist that blocks addons identified as malicious.
More information here: [http://www.computerworld.com/s/article/9193420/Mozilla_No_kill_switch_for_Firesheep_add_on?taxonomyId=17&pageNumber=1]

How do I call an external program

When I call an external program from Labview, how can I embed the interface into the front panel?

I'm running Labiew 6i for Linux. I'm using a system exec.vi to call an external program to do image manipulation (since there is no IMAQ for linux). How can I embed the user interface of the external program into the front panel of Labview?

As far as I know, the only way to embed other GUIs in LabView is an ActiveX in a container.
As long as you are using Linux, try to place (moving them on the desktop ) the two windows linked (like those 3 of WinAmp).

How can I run an external program without quitting Firefox?

I want to run an external program from within Firefox, much as Outlook express is run from the email button. How do I set this up?
Firefox doesn't import my Bookmarks from the listed html file. Any cure for this?

I don't want to run the mail program, I want to run another program.
Maxthon allows me to do this using External Tools. Does Firefox allow me to run other programs without leaving Firefox?
2. Firefox allows me to load an html file which contains my bookmarks, but it doesn't load the bookmarks file. is there a solution?

Returning Error Status back from Form to external program

Question,
I am trying to run a form essentially from the command line. I need to programatically catch any error codes that might have occured in the form by an external program. I can find nothing about returning errors back from the form or how to display it.
Any assistance is appreciated.

Hello Andreas,
Ah, sorry, there was so much talk about user decisions that I assumed you were using a standard decision task.
Still, I would be extra careful of changing the way workflow usually works because you have an unknown target audience that are based on the standard.
The standard SAP philosophy is quite simple: cancel/F3 or do nothing and it stays reserved. If you do not want it reserved, you need to perform an action. This is based on a majority of processes: in most cases when you execute a work item you will also be the one who is going to completed it. Replacing it is the lesser used of the two alternatives, therefore it is the only one that requires an action on the part of the user.
Again, this is intended as constructive input. Strange quirks and unusual behaviour tend to add a black mark to software if they do not make things easier to use. In many environments users are not even aware of the reserve/replace business, so there you would be adding an additional layer of complexity.
Personally I would find an exit popup annoying as a regular workflow user - regular decisions can be approved with one click, or I can back out with a single click if I need to make a phone call or look up some info before approving - but with this new-fangled thing I've got an extra button to click and an extra thing to think about. This is especially the case in a payment approval scenario where you may have users in some departments who may approve hundreds of payments each week.
My suggestion would be to leave it like that. By all means put an option into the user decision to put it back or to 'un-reserve' it (and loop round if the user chooses it). That way you are adding value and not clicks.
Cheers,
Mike

Insert into SAP table from external program

Hi Gurus,
I need to perform an insert of several records into a couple of SAP tables from an external program.
Do you know of an RFC (if it is remote enabled the better) that allows me to specify the table and records to perfom an insert?
Many thanks
Mauricio Pego

I don't know ABAP and wanted to avoid writing my own function if one standard exists.
My requirement stands like this, I have a few z tables that need to populate from my C# application by use of the .Net connector.
I haven't found a BAPI or RFC that allows me to add records to any table, but I don't know all the RFCs.
May be one of you passed throu this already.

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).

Call external program in background mode

Hi,
I am creating a PO using bapi BAPI_PO_CREATE1 in exit USEREXIT_SAVE_DOCUMENT_PREPARE.
I dont want to write the code in my exit. Instead I want to write the code in a Z program and call it in my exit.
My Problem.
How do I call my z program in my exit so that I can pass internal tables from my exit to the z program. Also I want to schedule the call of my external program for background processing.
I am trying with SUBMIT ZPROG AND RETURN. But not able to pass an internal table.
I tried PERFORM BAPI_PO_CREATE IN PRGRAM ZPROG, but in this case not able to schedule it in background.
Please advise.

How to execute external program in java?

My question is how to execute an external program in java.
I need to call a unix command in java.
Thanks.

it depends on what you are trying to do. Following are the two methods
1. Runtime.exec() : this method allows you just to call an external program as a seperate process
2. JNI (Native Interface) :- As of right now only C and C++ are supported by this method. This method allows you to directly call the C/C++ methods from JAVA
