Web Service; Error attempting to read from file

I'm trying to connect to a web service as outlined by the book "Creating Dynamic Forms with Adobe LiveCycle Designer" which is an excellent book by the way.
I'm receiving the following error "Error attempting to read from file. http://www.webservicex.net/BibleWebservice.asmx"
I've successfully created the Data Connection to
http://www.webservicex.net/BibleWebservice.asmx?wsdl
I dragged and dropped the bookTitle, chapter & Versie onto the form. I also dragged and dropped the GetBibleWordsByChapterAndVerseResult and the GetBibleWordsByChapterAndVerseBtn.
I Preview PDF and click the button I get the above error.
Does anyone have experience using Web Services with Adobe LiveCycle ES and have advice on how to resolve this. Any Suggestions would be greatly appreciated.
-Todd

Well, I have more news on the error I'm getting. - NO I didn't find the problem. Yet
I checked and made sure that web.config had "None" selected " in authentication mode. I.E. <authentication mode="None" /> This should eliminate any authentication problems since that turns off IIS's authentication checking.
At first I was thinking the form was generating the error trying to read the result coming back from the web service, but I put in some code that writes the result to a log file when the method fires off.
I noticed that when I clicked on the button on the form, the error message would pop up from Acrobat, but when I check the log file, there was NO entry. This means that Acrobat failed before it could execute the method.
Here is the web method:
[WebMethod(CacheDuration = 30,
Description="Returns the String 'True' or 'False' whether or
not you entered a 'T' or 't'.")]
public string TF(string Tf)
string result="False";
if(Tf.Substring(0,1).ToLower()=="t"){
result= "True";}
LogFile.Write("Sent: "+result);
return result;

BDC read from file!

Dear friends,
       I have one problem. When we are creating abap program by clicking on program button on recording screen it asks for the program name and there are 2 oprions..
1) read from file and
2)transfer from recording....second one is fine...but i am not able to use first option...how to use that and why it is used...
Thanks And Regards,
Bhavin Shah.

Hi Bhavin,
      The basic difference between read from file & transfer from recording is that...
    In transfer from recording you have to give a session name or you have to choose call transaction. Here you have to give the data manually.
    The Read from file will generate a dataset where who have to give that path of your flat file. When you execute it the data from the flat file will go into the necessary fields you have choosen before. You can process the job in the back ground which will be executed and a log file will be generated so that you can check whether it is updated correctly or not.
      In general we use read from file option when we know that the data are correctly arranged for recording.
      For eg. if you want to update the database with the file you have to know the datatype and length of each database-field so that you can specify the data in a file.
      i.e Assume that you are having 2 fields in db-table of type char and length 10 & 20. Assume that you are going to give values for these fields as mala & kala.
In the file... you should specify like this...
mala      kala                xxx
123456789012345678901234567890
<---Ten--><-----Twenty------->
In a Real Time scenario you have a very large table with 50 to 100 fields to update with a very large data like 1000 - 10,000 records and if you are not sure with the flat file data. Then you should not go for the file option.
Hope this helps you.

I will very appriciate if someone can help me solve it. I was trying to set Full control for my account in Properties/Security of root folder and try again but error is still.
Many thanks

Hi Foreverduy,
Before you run SQL Server 2008 express setup, make sure that you have installed Windows installer 4.5 and.NET Framework 3.5 SP1 manually. For more information about the process, please refer to the article:
http://msdn.microsoft.com/en-us/library/ms143506(v=sql.100).aspx. Moreover, please turn off all the third-party softwares which could prohibit the installation process.
According to your error message, the issue could be due to that your account has no rights to install SQL Server, or the corruption on the media.
Firstly, please ensure that your account has admin rights. Also make sure that you right-click the setup.exe and choose “Run as administrator” to complete the installation.
Secondly, please check if "msdbdata.mdf" file exists at d:\8268cd7b247d294de359c9\x86\setup\sql_engine_core_inst_msi\PFiles\SqlServr\MSSQL.X\MSSQL\Binn\Template. If it exists, please make sure that your account has read permission to the extracted
folder.
However, if the file doesn't exist in the extraction, the media could be corrupt. Please download the
media
again and check if the issue still occurs.
Regards,
Michelle Li

I want to read a file which is in a zip and this zip file is at ftp site

i am facing this problem and try to find the solution from last month please help me
i want to read a file which in ziped and this zip file is at ftp site. and i want to read this file without downloading this zip file to local machine. i have to read it from ftp location only

You can open an URLConnection to a file on an FTP server (search this forum to find out how). You can get the InputStream from the URLConnection and feed it to ZipInputStream. That should do the job.

I found the installActions file in the installer folder and I think this could be the problem

though I am attaching the log file for more details do you think the installer is corrupt :(

Read from file and plot data against timestamp

Hello,
I know that there are already many posts regarding the question I m about to ask. But, I somehow dont seem to achieve what I want using the suggestions given in the other posts.
My problem is that, I have a file with the first column as a time stamp containing hour, minute, second and millisecond. The second column in a set of pressure values. I want to plot a graph of these pressure values against the timestamp recorded in this .txt file. Whatever I do, the timestamp values seem to skip by a couple of seconds.
How do i do this correctly?
Also, Is it advisable to use the read from file or the read from spreadsheet file vi? Kindly help me out.
Thanks and regards.

Hey, I was having a similar issue the other day. The first problem I had was how to open the file and actually get the timestamp information. Since I'm using LabView 8.0, I had to go into Read Spreadsheet File and create a new vi to open strings (in an array form). That's the Read Spreadsheet File (string) vi below. Then, I had to figure out how to convert the string of a timestamp to something meaningful to me. The Timestamp2.vi is how I did that below. I'm also including a little test file. So, to run Timestamp2.vi, you will have to input the right base path, and have the Read Spreadsheet File (string).vi in the same place as Timestamp2. Hope that helps. I think I'm finally getting this stuff, so let me know if it doesn't work.

Is there is abetter performance to read from file than my code for longfile

Hi
This is my code to read from file and show it in a text area ,but for long file it wait for along time to show the file ,Is there is better performance code?
chooser=new JFileChooser();
                    chooser.showOpenDialog(sav);
                    File fe=new File(chooser.getSelectedFile().getAbsolutePath());
                    //out = new PrintWriter(new FileOutputStream(f));
                     in2 = new BufferedReader(new FileReader(fe));
                     str=in2.readLine();
                     if(str!=null)
                         nn2=str;
                     str=in2.readLine();
                    try{
                     while((str)!=null)
                     { nn2=nn2+"\n"+str;
                         str=in2.readLine();
                     }}catch(NullPointerException e){}
                     jta2.setText(nn2);
                      in2.close();
                   // in2 = new BufferedReader(new FileReader(fe));
                } catch (IOException ex) {
          }catch(NullPointerException e){}
              nn1=str;

Yes you code would be slow because you are continually creating new string by concatenating one string to another.
The easiest way is to simply use the read(...) method of the text area.

Read from file at a particular rate

hi
could anyone tell me if its possible to read from a previously stored text file at some required rate?
( for example if i have 100 entries in my file i wish to read one value every 5 seconds)
thanks in advance
Solved!
Go to Solution.

First, you'll have to learn not to use Express VI's. (Look in example finder for examples on file I/O)
1. You have no good control over the way it accesses the data.
2. It puts out the annoying dynamic datatype which hides what the data is, and makes you jump through hoops to get the real data out of it.
Second, you need a loop. Right now your code is set up to just run as a single shot.
Here is how you would read one line at a time with a 2 second delay. (Note that the read text file was set in its right click menu to "read lines".)
Another alternative, (and probably better), would be to read the whole file at once, and then just index the values out of the resulting array in a loop with a 2 second delay.
The formula express VI's are doing some operations that could be handled easily with native LabVIEW code. I would get rid of those express VI's. The first formula node has some pretty basic operatons as well. The bigger formula node could also be done with basic LabVIEW operations, but the coding logic going on in there is complicated enough that I would probably leave that formula node as it is.

Reading from file one at a time

I am trying to read from an Excel file one cell at a time, and am having some trouble. I have included my VI. Any help would be greatly appreciated.
Attachments:
demo.vi ‏165 KB

Your first problem is that you are using the Read file function. This doesn't work with Excel. Native Excel files have their own special format and you have to use ActiveX to read them. If you have the report generation toolkit, you can use that or look at the examples on the Excel Board. You can also save the Excel file as comma or tab separated text and then the Read From Spreadsheet or Read File will work.
Second, if the file is static, you would be much better off to read the file all at once to an array and then just index out the values inside the while loop. It looks like you are getting temperature values from a file. Is the Excel file being generated at the same time as your program? If it is, what is generating the file? Maybe that program can be controlled by LabVIEW and you can get the temp values directly from it. If it's a file that is constantly being updated, then the reading is going to be somewhat comlpicated if you care at all about getting the most recent value.

How to read a file which has header and without header

Hi,
I have a file to file scenario wherein there are txt files in the source system, some of which has header and some without header.
How does the sender adapter dynamically identify a file with header and without header.
I knew that File content Conversion in the sender adapter with "Recordsets per message = 1" can read the header. But how to handle dynamically.
Thanks in advance for suggestions and advice.
Regards.
Praveen

Hi,
Let me give a more clear picture:-
One of my file which has header and the corresponding values is listed hereunder:
PERNR;KID;PNALT;NACHN;NAME2;VORNA;TITEL;TITL2 and so on.....
;1200;1200;Angus;; and so on.........
Other file which has no header but only values in it:-
1200;1200;;Werner;Angus and so on.......
The structure remains same for all the files. The only difference is that some of the file has header in it and some without header. The Message Type is mentioned hereunder:-
DT_LegacyEmployee (Category - Complex Type)
     Employees (Category - Element, Occurence - 1)
          Employee (Categroy - Element, Type - DT_LegacyEmployee_Row, Occurence - 0...unbounded)
               PERNR
               KID
               PNALT
               NACHN
               NAME2 and so on......
I read the file in record row. The file conversion parameters in the file sender adapter are mentioned hereunder:-
Document Name - MT_LegacyEmployee
Document Namespace - http://abc.com/xi
Recordset Name - Employees
Rescordset Structure - Employee,*
Recordsets per Message - 1
Key Field Type - String (Case Sensitive)
Employee.fieldSeparator - ;
Employee.endSeparator - 'nl'
Employee.fieldNames - PERNR,KID,PNALT,NACHN,NAME2,VORNA,TITEL,TITL2 and so on........
How do we dynamically identify whether the file has header or not. Even if the file has header or without header, the file needs to be picked and transferred to the target system. Kindly clarify.
Regards.
Praveen

HT1338 i have tried to update the iPhoto in an iMac from 2010 which i have updated from Snow Leopard to to Mountain Lion but its impossible.What can i do?

i have tried to update the iPhoto in an iMac from 2010 ( in which i have updated the OS from SnowLeopard to Mountain Lion 10.8.3) but it doesnt work,why? Is my iPhoto too old to update do i have to buy and install a new version of i Photo ?

You may need to buy the newest version from the App Store. If you cannot update via the App Store then you are using the version from a DVD. Updates for that can be downloaded from support.apple.com/downloads/.

Java Applet that reads from file

I'm quite new to java, I'm fiddling around with it for a nonprofit organization.
I have a java program that reads from a specified file and generates output but my final goal is a search box on the website that will take user input, run it through my program which searches through a prespecified file, and generate output.
I'd appreciate any help.

What can I do with this? I need it to be a String because I'm breaking it down to Tokens.
Thanks,
-Grant
Scanner input = null; //input is going to be the Scanner object
input = new Scanner(new BufferedReader(new FileReader("test.txt"))); /*setting up the Scanner object "input" to read the file "test.txt"*/

while (input.hasNext()) { //Puts ALL the file's data into one string
words = words + " " + input.next(); /*Without that space the string "words" contains is all just one word making it unTokenizable*/
}
