Webutil_file_transfer.AS_To_client

Hello,
The webutil_file_transfer.AS_To_client only works in ascii mode. Therefore on Unix we add the command unix2dos to workaround this problem.
The code is as follows:
if upper(get_application_property(operating_system))
not like '%WIN%'
then
host('unix2dos '||g_ap_directory||g_file_name
||' '||g_ap_directory||g_file_name);
end if;
if not webutil_file_transfer.AS_To_Client
( user_preferences.get_output_directory||g_file_name
, g_ap_directory||g_file_name
then
end if;
This works fine the first time the code is executed. The second time the code fails. The unix2dos does not do the job. When we do not do the file transfer it does work ok.
Looks like the webutil_file_transfer.AS_To_Client prevents other actions on the AS.
Any ideas?
Regards Erik

You may need to clear your variables and find some way to reset everything after the function is complete. That would be my first guess. Nothing is jumping out at me from the code at the moment.

Problem using webutil_file_transfer.AS_to_Client

I have configured webutil package successfully
I have made the following configuration to webutil.cfg:
transfer.database.enabled=TRUE

#List transfer.appsrv.read.<n> directories
transfer.appsrv.read.1=c:\temp

     ELSE
          message('Upload was successful');

Webutil_file_transfer.as_to_client WUT-121 error?!

I am trying to transfer a .csv file (22k) from my Apps Server using webutil_file_transfer.as_to_client('c:\temp/','c:\epsis/reports/serv.csv') command.
I have amended my webutil.cfg to allow file transfers and other webutil functions work fine so I am presuming the install is good.
I continue to get the WUT-121 error but don't understand why. Any suggestions?

To transfer from the App Server to another machine, you have several options:
1. Use the HOST command. This may be difficult depending on the server's platform and security configuration. If Windows, by default the process (Forms) will not have permission to access network resources (i.e. mapped/shared drives). You will need to refer to the Microsoft documentation in order to overcome these restrictions.
2. Use HOST to execute a ftp connection for transferring the file. Of course the remote machine must support ftp. If you have access to "My Oracle Support", see note 110531.1
3. Create a java class which could be imported into the form that can perform this task. Refer to the Forms Java Importer documentation for information about importing java for server side execution. Also, here is a starting place for the java information:

Problem reading file after using webutil_file_transfer.as_to_client

Hi all,
The Forms webapplication I'm working on has to talk with a cardreading-application on the client-PC. The communication is carried out by exchanging small files. Reading from the client by Forms on the AS goes well (using client_text_io from webutil). The problem arises when the application has to respond back with a file. The file is made on the AS and then transfered from the AS to the client using webutil_file_transfer.as_to_client. This file can not be read by the cardreading application when the AS is on Linux. Our developement AS server is on a Windows 2000 box and then the communication doesn't show this problem.
If I open the file from the AS on Linux , I can see that there is only 1 long line. The Windows version of the file contains 2 lines (as it should be). It seems that before/during/after the transfer some special characters like carriage return and tab are causing the problem.
Looking in web_file_transfer.as_to_client I see that the procedure reads lines from a temporary file into a buffer. The lines are separated by a CHR(10). Could the transfer from Linux to Windows(DOS) cause a problem with these characters ?
Has anyone experienced this problem ? If someone has a clue this would be very welcome.
We work with :
- Forms and AS 10.1.2.0.2
- Webutil 1.0.6
- Development OS: Windows 2000 (Service Pack 4)
- Production OS: Red Hat Enterprise Linux AS release 3 (Taroon Update 3)
- Client-PC OS: Windows 2000 (Service Pack 4)
Thanx,
Enrico

Without going into a long winded answer, the only thing I can really offer is to say this... If you feel as though your code has been correctly written and you simply cannot identify any other possible solution, add SYNCHRONIZE. In short, its execution acts similar to a reset or refresh button.
Another common place where SYNCHRONIZE has been helpful is when calling RUN_REPORT_OBJECT. For example, if you use the code we offer in the Forms/Reports Integration document you will find that it works very well - most of the time. However, sometimes it fails for what seems to be unexplainable reasons. If you message out the values being assigned you will see that some variable values are not being set even though the code execution has already passed the point where a value should have been assigned. Adding the SYNCHRONIZE just after the point where the value should have been assigned forces the assignment before executing the next line of code. For example,
     v_rep := RUN_REPORT_OBJECT(repid);
     rep_status := report_object_status(v_rep);
In the above code, a request for a report is made followed by a check of its status. At this point you would expect that the status would be something like one of the following:
     'RUNNING', 'OPENING_REPORT', 'ENQUEUED'
However, we have seen instances where the value assigned to the variable would actually be NULL, which of course will make the rest of the code likely fail. By adding SYNCHRONIZE the problem is correctable.
     v_rep := RUN_REPORT_OBJECT(repid);
     rep_status := report_object_status(v_rep);
     SYNCHRONIZE;
It is important to understand, however that using SYNCHRONIZE comes at a price. Each time it is executed a network round-trip occurs which will give the application the appearance of degraded performance. So use this built-in only when you know you must.

Problem with webutil_file_transfer.as_to_client

Hi all,
I am migrating some Forms/Reports from 6i to 10g, well, when i make a report sometimes i want to save some of those reports from server to client.
For doing this i am using the WEBUTIL functinality with webutil_file_transfer.as_to_client.
this works fine with some reports but doesn't work with other ones, but the problem is that no error appers, it just doesn't write the report, so i don't know what is the problem
thx in advance.

Hi Michael,
I have found what it's the problem.
As i said i am upgrading reports from 6i to 10g,
when i run the report in 6i, the report is generated always with data, for example, if the result of the query is nothing, the report is created with the date, name of the report, and some other information that appears in all of my reports by default, so the report is created and then transferred.
when i run the report in 10g, and the result of the query takes back some data, the report is created in the the server and then transferred properly, but when i create the report as a txt file, it's created without the default data, i don't know why, but those data doesn't appears, but only in .txt files, it works perfectly with .pdf file.
So the problem comes when the user run's a report with no query result, then in the OracleAS it says it's has been created, but as it's empty, it doesn't tranfer the file to the client machine.
It's a very strange thing, i don't understand why in 6i it adds the default data to the report, and in 10g it doesn't add that default data...
P.S: As my english is not very good, when i say default data, i mean eveything that is not returned with the querys of the report, for example the date, the name of the report...
Do you guys have any idea of why this could happen only with txt files?
thx for your time!

WebUtil AS_TO_CLIENT Problem

<9iDS 9.0.2 RedHat 8.>
I am running a procedure from a shared library, pretty much copied from Frank Nimphius' RUN_REPORT_OBJECT_PROC procedure. This library, and the WEBUTIL
library, as well as the WEBUTIL object group is attached to my form. If I comment out the call to XXXX.RUN_REPORT_OBJECT_PROC my WEBUTIL_FILE_TRANSFER.AS_TO_CLIENT function works fine, but as soon as I put the RUN_REPORT_OBJECT_PROC before the AS_TO_CLIENT call, it runs the report ok, then when it gets to AS_TO_CLIENT the form crashes and I get this in the Java Console:
oracle.forms.net.ConnectionException: Forms session <16> aborted: unable to communicate with runtime process.
     at oracle.forms.net.ConnectionException.createConnectionException(Unknown Source)
     at oracle.forms.net.HTTPNStream.getResponse(Unknown Source)

     at oracle.forms.net.HTTPNStream.flush(Unknown Source)
     at java.io.DataOutputStream.flush(Unknown Source)

I tried switching the order of the attached libraries.

Webutil file transfer problem

I have a problem, I am using webutil_file_transfer.AS_To_Client to copy a file in a directory, but when I want to delete the original file with webutil_file.delete_file I get the error that the file is in use and it remains blocked until I close the application and the console of Java is closed too.
How can I solve this?
Thanks in advance.

v_origen := 'C:\archivo.pdf';
v_destino := 'D:\archivo.pdf';
l_success := webutil_file_transfer.client_to_As(v_origen,v_destino,false,null);
if l_success then
SET_ALERT_PROPERTY('ALT_INFO',ALERT_MESSAGE_TEXT,'File saved);
ALERTA := SHOW_ALERT('ALT_INFO');
else
SET_ALERT_PROPERTY('ALT_INFO',ALERT_MESSAGE_TEXT,'ERROR File not saved);
ALERTA := SHOW_ALERT('ALT_INFO');
end if;
-- delete de original file
l_success := webutil_file.delete_file(v_origen);
if l_success then
SET_ALERT_PROPERTY('ALT_INFO',ALERT_MESSAGE_TEXT,'Deleted OK);
ALERTA := SHOW_ALERT('ALT_INFO');
else
SET_ALERT_PROPERTY('ALT_INFO',ALERT_MESSAGE_TEXT,'Deleted NOT OK);
ALERTA := SHOW_ALERT('ALT_INFO');
end if;
The first message is l_success=true, the second message is l_success=false.
I want to copy the file of a directory to other one and to delete the original one (to move the file).

Webutil_file.copy_file slow in copying files

Hi All,
I've read about this problem previously and I'm finally suffering from it myself.
It took between 5 and 10 minutes to copy a 500k file between two network drives connected to my client. How slow is it going to be for the 100Mb files we will want to copy?
Has anyone found a solution? IS the only speedy alternative to use client_host and the copy command? I was hoping that the webutil_file.copy_file was a more elegant solution to the file copying process!!!
TIA
Tony

Hello Tony,
That would be fine if I wanted to transfer from the AS to the client.
But I want to transfer between two network drives on the client,
these drives are not visible to the AS at the moment.My understanding is that the functions are executed on the client and therefor the network drives have to be visible to the client and not to the AS.
But currently i'm working in the OC4J and my server and client are the same.
So it is not really tested.
Is the AS to client copy much faster than the copy_file on the client?
Why would that be? Is it access to network drives on the client that is slow?Yes it is faster. The procedures use different implementations. Files don't get divided in chunks when webutil_file_transfer.AS_to_Client is used.

Disregard my last. I see what you are doing. You are using file transfer to move the file to the local machine. It was confusing because the paths are the same.
I would suggest adding a SYNCHRONIZE after the file transfer and before the attempt to print. It might even be a good idea to add some error handling code to verify that the file has been copied and can be found. This will allow you to better deal with situations where the file doesn't get written for some reason. WebUtil offers some functions to check for file existence and size.
Also, if you are using Java 7U21, this may cause some issues with your CLIENT_HOST call.
