Reading the output from a object running in the local machine.

Reading the output from a object running in the local machine.
By using a signed applet i am lunching a small application that returns an image object, how to read that without storing it in the hard disk.
Which means i need to read the image object return by the local application using applet or jsp .
i am using tomacat and an html page with an applet with it to lunch the application.

You can write that image in a binary format using OutputStream for System.out and then read it in your applet.

What is the best way to run two programs simulataneously using the output from one to run the other?

I just kind of wanted to get an opinion from some people on here. I have two main VIs. The first is a DAQ system that reads 99 different sensors and feeds that data into an array. The second is a real-time processing system that is designed to take the array and do numerous calculations. Both VIs output data to the front panel that I want to see, so I don't want to just use one as a SubVI.
Is there a simple way to run both VIs, using the output from the DAQ system to feed the processor so that you can easily see the front panels of both VIs? I had considered just copying the real-time processor code into the DAQ VI, but I'm worried the resultant VI will be very large and unsightly.
On a side note, am I over thinking this? Excuse me if this is a rather dumb question, it's been a long week...aaaand it's Wednesday.
Solved!
Go to Solution.

There are a number of ways that you can go about this, but having both front panels open isn't a problem (assuming there is screen space!). Both could be sub-vi's of another "calling" vi, with their front panels set to open when called. The data from the DAQ side can be sent to the other through a number of ways, "producer-consumer" (many threads about this topic, examples in the LabVIEW examples, etc.) is one of the more robust techniques. If created correctly it allows one to run at a different rate than the other, although if the producer is "producing" much faster than the consumer can "consume" it will end up with problems.

Need to fetch results as the output from QGA2

Hi Gurus,
My scenario is that i need to develop an interface in which I would send Material,Plant,MIC and Period from one system to SAP R/3 and I need to fetch the output as I get the output from QGA2 while i enter the above mentioned fields.
Input: Material,Plant,MIC and Period
Output:
1) Inspection Start Date
2) Inspection Lot number
3) Material
4) Material Description
5) UD code and code group
6) Quality Score( at inspection lot level)
7) UD code text
8) Valuation of characterstic
9) System Status of lot
10) Characterstcic description
11) Operation Number at which charaterstic was inspected
12) Characterstic Number inspected
Please let me know any BADI or FM which could help me in fetching out these values as standard QGA2 transaction does fetch out these values.
Thanks

Best regards,

Please note that I cannot seee the output from wndows command : del *.* and the java class execution does not finished.
I I will replace the above command with the dir command then the output of the command is visible.
Would you give me a hint about how to modify the above clases in order to parse the output of the del *.* ?
No - but I will give you a hint about ProcessBuilder and how to develop software properly.
Hint #1: Don't try to automate something that you don't know, or understand, how to do manually.
a. Do you know how to execute 'del *.*' manually in a command window?
b. Did you try that manually to see what happens?
My guess is 'no'. If you had you would know that the response to a 'del *.*' command is going to be this:
Are you sure (Y/N)?
And your 'java class execution' doesn't finish because the 'del' command is waiting for you to answer that question.
Hint #2: Don't try to use ProcessBuilder for an application that requires console input unless you first know how to provide that console input via your Java code.
Your code will wait forever since it does NOT answer that question.
Search the net and The Java Tutorials and you can find examples of executing command line utilities. Then try those examples first and make sure that:
1. They work for you
2. You understand HOW they work
Then you can modify those examples to do what you want to do.

Hello ejp,
First of all i thank you for the reply.
I explain the process which i am doing in side the thread.
After connecting to the remote machine, it asks another password.
so i read the output after connecting. if it equals "password:", then write the 2nd password. then i read the output. it will be like "system>" . if this prompt comes like this, then i write the super user name and super user password. then the prompt will be like "system#". then i write the command which i need to execute and read the output whether the command is success or not.
So after every output read, i interrupt the thread using interrupt() method. its working fine if i execute via GUI ie, click the button. But its not working when i scheduled this job in a scheduler ie, it will be executed when the time elapsed.
Give an idea to fix this bug please.

Reading the output from another program.

I haven't used Java in a good long while so I need someone to point me in the right direction. I have a C program that I call from a command line (windoze boxen) and it spits out some neat data. I can call it from inside a Java program, but how do I then read the output from the calling Java program? I'd just alter the C program, but I lost the source.

This article explains how to correctly execute another program from your
Java program, and read its output:

yes, that is correct that it crashes with the new code when i have both made it a separate library function node and when i incorporated it into an existing code. the odd thing is that it actually seems to work now. i believe that i was using the wrong environment to call the new codes, which is why whenever i tried to revert to the original code previously, it still crashed. it seems that in order to be called, i need to use Deployment rather than Development and ppc instead of i386 in the active configuration and architecture in Xcode, respectively. while playing around with the iphone app, it must have reset my defaults to a non-labview friendly form. so now that i've got that part of the code working, i need to find out why it's still crashing on me. at first, i thought it must be the random number generator, but testing that separately in the code works just fine, so there must be something internal in the code. probably a memory allocation fault. but now that i can actually get everything running once more, i should be able to sort that issue out myself.
thank you very much for the help. sorry i didn't actually have anything to fix, unfortunately. i'm going to spend some time trying to debug this section of code to find where the fault lays. i may come back if i cannot find it in there, but hopefully it will not come to that.
take care and many thanks,

Discoverer report - Output from Discoverer plus is not the same as Discoverer desktop

As a part of Upgrade project we are migrating the discoverer reports from 11i (11.5.10.2) to R12 (12.1.3) .After migrating to R12, for a custom discoverer report the output given by discoverer desktop is correct (24 rows for a scenario). But the report output from Discoverer plus does not show the credit transactions (2 rows). The output from Discoverer plus shows only 22 rows (24 - 2), which is incorrect. The query is the same in Discoverer desktop and Discoverer plus.
Please let me know why these transactions that are appearing when the report is run from discoverer desktop are not appearing in discoverer plus. Is there any setup in discoverer plus for this?
Regards,
Brajesh

Pretty hard to answer a question like this. Best bet would be to copy the existing discoverer plus book and start removing conditions, fields, etc until those two rows from desktop show up and see if you can work it out.

Page breaks appear in the spool output of report when run in the background

Hi All,
Report is using fm 'REUSE_ALV_GRID_DISPLAY' to display the report. parameters passed to this fm for display are :it_fieldcat,is_layout,it_events,t_outtab.
Page breaks appear in the spool output when report is run in the background.These page breaks needs to be removed. When executed in the background, the excel extract should be the same as if pulling directly from the report itself.
How to remove the page breaks in background?
Thanks & Regards,
Abhishek Singh

Hi
You can use the below code , which the reprt run in background. If you run the report in background thenyou need to use 'REUSE_ALV_LIST_DISPLAY'
if sy-batch = ' '.
call 'REUSE_ALV_GRID_DISPLAY'.
else.
call 'REUSE_ALV_LIST_DISPLAY'.
endif.
if you are using OO alv then write this code..
CALL METHOD cl_gui_alv_grid=>offline
RECEIVING e_offline = off.
IF off IS INITIAL.
CREATE OBJECT g_custom_container
EXPORTING container_name = g_container.

Opening a text file in server from an applet running in the client

Friends,
I want to open a text file in the server(The server machine uses tomcat 4.1.12 server)from an applet running in the client machine;
The applet invokes a servlet that opens the text file;this text file is opened in the server machine; but I want it to be opened in the client machine where the applet is running.
Plese help me to get around this.

You can open the textfile on the servlet and then send the information to the client (applet) as stirngs. The must then applet convert the stirngs into some object or simply display the information in someway. But then the text file that you are opening must be stored in some relevant tomcat directory e.g. on the server. If you want to open a file on the clients computer, you get into signed applets.

What is the proper interpretation of the output from PID vi?

Can someone clarify the meaning of the output from the NI PID vi's? From the documentation for the PID control toolkit, it appears that the output is an absolute quantity and not a delta (change) to the previous output. The problem I have is that if I am running proportional control only, and the controller is moving into a steady cooling air flow rate to achieve my setpoint temperature, the error goes to zero and the output from the controller drops to zero. This completely ruins the temperature control.
Simply: assume that the output to the control valve I am using needs 12mA (4-20mA controlled) constant value (flow rate) to maintain my setpoint. When the error goes to zero, the controller output goes to zero. This, of course, leads to terrible oscillation etc.
Other PID implementations I have used are all delta (change) based. In other words, you calculate a P, I, and D correction to the previous output.
What am I missing? All of the NI labview PID examples use the output directly to drive I/O, and never use it as a change (delta).
I read this newsgroup's archives and found a similar question, but the answer was not helpful.
thanks much in advance!

Hi Darth,
You have read the documentation correctly. The output of the PID VI is an absolute value. If you are using a P algorithm then you will need to use the PID Output Rate Limiter VI to control the rate of the oscillation. Your other option is to use a PID algorithm rather than just the P algorithm. The I and D portion of the PID algorithm are based on the current and previous error and output respectively. For further information on how the PID output is calculated please reference chapter 2 of the LabVIEW PID Control Toolset User Manual
Hope this helps!

The Output Post-processor is running but has not picked up this request

Hi
We are getting the following error when running an XML Publisher report in 11.5.10
The Output Post-processor is running but has not picked up this request.
We have checked that the SQL query in the data template works fine. Also, the XML output if we remove the template looks fine. The XML data and template also work fine when merged manually in MS WORD, and also if we create a Java class and run the XDO classes explicitly.
In Manage Concurrent Managers, the OPP seems to be running fine.
How can we debug this issue in an acceptance test environment without sysadmin access?
The problem does not occur in other enviroments.
I think this is not the error described in MetaLink Note 352518.1. This is the ONLY XML Publisher report in the system, so the OPP cannot be busy with other reports, and it is not giving the processing timeout error message (so case 2 is out of question).

You can change the logging level of the OPP to statement to see more detail in the log file
(One problem we have is if you are running of a shared APPL-TOP environement where the conc manager job has to run on the physical node)

InputSream in = p.getInputStream();
b...
do
System.out.println(b);
while ((b = in.read()) > 0)
But there is no way that I get the output in the inputstream. If I use the command "cmd script.pl", the output is displayed in the Dos box, but also not in the inputstream.
I will appreciate any help.

Try this

Hi sg,
Research the DDE option.
Dynamic Data Exchange (DDE) is a mechanism by which applications can communicate and exchange data in Windows.
I have imported data into the excel spreadsheet using DDE built in functions. I am sure it can work with MS Acess as well. If not, then you need to create a 2 step process .. reports -> excel -> access.
