Charles, you may be interested in mvExec. It will execute any command or program on any MV system from anywhere in your network. In your case, you don't need to be concerned about connectivity. All exchanges with Universe are done by executing a local command and reading local files that contain the results. This can be used by any language or tools that you choose and there is no need to learn any new language or protocol. Example: DOS Command: mvexec mvreaditem Uses configuration file mvreaditem.mv0 in a local windows directory to read a customer record from a production server account. Results are stored in \temp. Config file has 4 lines written at runtime: productionserver<--- name any server here EXEC.GET.ITEM <--- call your own program here |CUSTOMERS|12345<--- data for the program c:\temp\mvreaditem.mv1 <--- store results here Software download and full documentation with code samples is on our Freeware page: remove.pleaseNebula-RnD.com/freeware mvExec is completely free and can be used by anyone who already has mv.NET installed. [AD] If you don't have mv.NET you can purchase a single license from Nebula R&D or any other mv.NET reseller. Once you have an inexpensive license it can be used for many other purposes. HTH Tony Gravagno Nebula Research and Development TG@ remove.pleaseNebula-RnD.com Nebula R&D sells mv.NET and other Pick/MultiValue products worldwide, and provides related development and training services --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] Setting return code when a Universe process terminates
That is similar to what we are doing now, wxcept the web server is Linux so I use XMLHttpRequests to call a PHP module that calls a Java routine that uses Uniobjects for Java to get the results from Unidata. An open source product called JavaBridge is used to allow php to call Java. Works well, but pretty complex to setup. Thanks for the info.

RE: [U2] Setting return code when a Universe process terminates
Hi Any javascript will run in the browser and not on the server. What the javascript calls using XMLHttpRequest will exist on a server somewhere. XMLHttpRequest is the javascript DOM API that is the keystone of AJAX. You probably use that now to contact a webservice written in asp.net that then uses uniobjects to connect to u2. The same XMLHttpRequest call could also use my example php code to do a similar thing, but the php is fairly unsophisticated compared to uniobjects and will not work well if you have heavy load, no licences left etc + does not manage any pooling or device licencing. If you want to connect to a web page/service direct from within your asp.net - well here is a very simple example vb.net function to do just that - tho there are of course many ways to do this Private Function getWeb(ByVal url As String) As String Dim URI As Uri = New Uri(url) Dim webPage As String = String.Empty Dim WebRequest As HttpWebRequest = HttpWebRequest.Create(URI) WebRequest.Timeout = 8000 Try Dim WebResponse As WebResponse = WebRequest.GetResponse() Dim Stream As Stream = WebResponse.GetResponseStream() Dim StreamReader As StreamReader = New StreamReader(Stream) webPage = StreamReader.ReadToEnd Catch ex As WebException Err = ex.ToString End Try Return webPage End Function -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: 18 November 2008 14:46 To: u2-users@listserver.u2ug.org Subject: RE: [U2] Setting return code when a Universe process terminates >> Using whatever programming language you run to power your iis web site >> asp/asp.net/php etc. Or your iis web server dishes up static html which has >> a script it in that contacts the u2 server via ajax. .

RE: [U2] Setting return code when a Universe process terminates
Sorry - in reply to your statement "I am interested in finding a way to get to the U2 data more directly than we do currently" Then perhaps what you should do is use the u2 web services module to write and deploy a simple webservice that runs a basic subroutine, and you then code your XMLHttpRequests to use that url rather than going through your java bridge. The stack would be Browser runs XMLHttpRequests -> u2 web services -> u2 subroutine -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: 18 November 2008 14:46 To: u2-users@listserver.u2ug.org Subject: RE: [U2] Setting return code when a Universe process terminates >> Using whatever programming language you run to power your iis web site >> asp/asp.net/php etc. Or your iis web server dishes up static html which has >> a script it in that contacts the u2 server via ajax. .

Ahh subtle difference our udt box is A web server but not our main one. Our

by default. So no rexec but to do it remotely you just call the web page
from your other app/website/javascript etc.

RE: [U2] Setting return code when a Universe process terminates
What about if you had a unix directory call ../truefalse If the output of UD/UV program is good, then "touch ../truefalse/PID" If the output of UD/UV program is false, then "/bin/rm ../truefalse/PID" then RUN BP $udtProgram ; cat ../truefalse/`method-of-returning-current-pid` I can't remember how to return your current PID. The idea is that if the UV program is ok, create a file so the cat command returns a 1 (successful), if the UV program output needs to be not ok then make the output of the cat command unsuccessfull (file non existant).

Again a similar thing in php - I look for a certain string in the output and
use that as a return code
$udtCmd="LANG=en_US.UTF-8;export LANGcd

$result = array();

Ian, I tried for a long time to figure out a way to do this entirely from
within UD. Couldn't figure it out. I hit two walls. First, the exit code
that nix receives is the status of the udt command. If you're program runs
at all, you get a '0'. The second wall was when I tried setting an
environment variable from within my code. The issue there is that shelling
out starts a new shell that is closed as soon as you return to UD. The
only way I could make it work was to echo a status code to an ascii file.
I ended up using a shell script to call my UniBasic program and pass in a
location and name of an ascii file. The program determines exit status and
echoes it to the ascii file. After the program completes, the shell script
checks the contents of the ascii file and does an 'exit #'. I've had this
working for a couple years with no issues. I'd be willing to discuss
