Hi,
we are migrating forms 6i to 10g..we need to upload contents of a file to database..this was working fine where app server and dev suite are on single machine..If we want to do it with a separate apps server before uploading to database the file is to be transfered from client to a folder in server and then upload asusual..i came to know abt this function .. WEBUTIL_FILE_TRANSFER.CLIENT_TO_AS_WITH_PROGRESS()

not knowing how to code it exactly..can any 1 tell me the code to use it if my source file is in c:/devsuit/forms/xx.out and to transfer to c:/devsuit/forms/datafile/xx.out. and delete this file from temp folder after uploading

Hi,
I use a similar coding to download a pdf report from App server to client.

lv_ret := WEBUTIL_FILE_TRANSFER.AS_To_Client_with_progress(lv_clnt_file, lv_srvr_file,
'Download from Application Server in progress', 'Please wait');

IF lv_ret = TRUE THEN
--Open the file from client machine
Web.Show_Document('file://'||lv_clnt_file,'_blank');
ELSE
PROC_SHOW_ALERT('ERROR','REPORT ERROR','Error in generating Rating Reports',lv_alrt_bttn);
END IF;


Is there anyway to catch the WUT error in particular (e.g error due to not enough space in H:\) from my oracle forms? Please explain.

Hello,

I got error when try to upload few file at one time.
Here is the error WUT - 116. From the help it asks to Check that one transfer is complete before starting the next.

My question is how to check that.

Here is my procedure.
PROCEDURE PR_INS_ATT(NEW_ATT varchar2) IS
	att_id2 number;
	result boolean :=false;
	RESULT2 boolean :=false;
	att_path2 varchar2 (1000);

		commit;
	
		--:isr_main.new_att := null;
		commit_form;
  
END;

Here is how I call the procedure.
	if :isr_main.new_att1 is not null then
		PR_INS_ATT('NEW_ATT1');
	end if;
	if :isr_main.new_att2 is not null then
		PR_INS_ATT('NEW_ATT2');
	end if;
	if :isr_main.new_att3 is not null then
		PR_INS_ATT('NEW_ATT3');
	end if;
	if :isr_main.new_att4 is not null then
		PR_INS_ATT('NEW_ATT4');
	end if;
	if :isr_main.new_att5 is not null then
		PR_INS_ATT('NEW_ATT5');
	end if;

There was only one file could be transfer when I save.
For info records were inserted in my table but only one file transfered.
Any suggestion is much appreciated.

Thanks and regards,
dayang

Hi,

One of my friend told me to do looping to check if the file has been transferred or not. So I modify the code to this.
PROCEDURE PR_INS_ATT(NEW_ATT varchar2) IS
	att_id2 number;
	result boolean :=false;
	--RESULT2 boolean :=false;
	att_path2 varchar2 (1000);
	DIR_SUCCESS BOOLEAN :=false;
	ISR_DIRECTORY VARCHAR2 (200);
	ISR_DIR2 VARCHAR2 (200);
	mkdirc_path2 VARCHAR2 (200);
	mkdirc_name2 varchar2(50);
	cd_test varchar2(200);
	s_FILE_PATH varchar2(200);
	s_NEW_ATT varchar2(100);
	
BEGIN
	select isr_dir, mkdirc_path, mkdirc_name
	into ISR_DIR2, mkdirc_path2, mkdirc_name2
	from isr_info;
	
	ISR_DIRECTORY := (ISR_DIR2||:ISR_MAIN.INC_NUM) ;
	cd_test := 'cd '||mkdirc_path2||'; '||mkdirc_name2||' INC'||:ISR_MAIN.INC_NUM||'';
	HOST(cd_test);
	Synchronize; 
	
	case
  when NEW_ATT = 'NEW_ATT1' 
  	then s_NEW_ATT := :isr_main.new_att1;
  	s_FILE_PATH := :PARAMETER.FILE_PATH1;
  			message(s_FILE_PATH);
		message(s_FILE_PATH); 		
  when NEW_ATT = 'NEW_ATT2'
  	then s_NEW_ATT := :isr_main.new_att2;
  	s_FILE_PATH := :PARAMETER.FILE_PATH2;
  			message(s_FILE_PATH);
		message(s_FILE_PATH);	
  when NEW_ATT = 'NEW_ATT3'
  	then s_NEW_ATT := :isr_main.new_att3;
  	s_FILE_PATH := :PARAMETER.FILE_PATH3; 	
  when NEW_ATT = 'NEW_ATT4'
  	then s_NEW_ATT := :isr_main.new_att4;
  	s_FILE_PATH := :PARAMETER.FILE_PATH4;
  else
  	s_NEW_ATT := :isr_main.new_att5;
  	s_FILE_PATH := :PARAMETER.FILE_PATH5;
  	
  end case;
	
  	select (max(att_id)+1) into att_id2 
		from isr_att
		where inc_num =:ISR_MAIN.INC_NUM;
		
		if att_id2 is null then
			att_id2 :=01;
		end if;
		

		
	--	att_path2 := (ISR_DIRECTORY||'/'||att_id2||''||:isr_main.new_att||'');
	att_path2 := (ISR_DIRECTORY||'/'||att_id2||''||s_NEW_ATT||'');
	
		BEGIN
		message(att_path2);
		message(att_path2);
	RESULT := webutil_file_transfer.client_to_as_with_progress
		                                              ( s_FILE_PATH
		                                              , att_path2
		                                              , 'Proses Muatnaik'
		                                              ,'ke'
		                                              , TRUE
		                                              , null );
		SYNCHRONIZE;
		
		  	
			IF RESULT = true THEN
				message('done trnasfer');
				message('done trnasfer');
				RESULT := false;
				insert into ISR_ATT(att_id, inc_num, att_date, att_by, att_details, att_path) 
				values(att_id2, :ISR_MAIN.INC_NUM, sysdate, :parameter.P_LOGIN_USER, s_NEW_ATT, att_path2);
				commit;
				RETURN;
			ELSE
				PR_INS_ATT(NEW_ATT);

			END IF;
			EXCEPTION WHEN OTHERS THEN
				message('error');
				message('error');
			END;
		
  
END;

Both file could be transferred. However the first file is 0 byte and I got this error WUT-125 which I checked in Help it says:
Quote:
Checksum error closing file on application server. Type: User Description: When an upload to the application server completed the file size was not the value expected. Resolution: Retry the upload operation and check for sufficient disk space / access on the middle tier


For info, I tried to use the same code and trigger the procedure from a button for each file. All files could be transferred successfully.

Could anyone help me regarding this.
Any suggestion is much appreciated.

Thanks and regards,
Dayang

The webutil documentation says Quote:
Note: Asynchronous mode offers better re-drawing of the Forms screen while the transfer takes place, but will not offer the ability to carry out significant work while the transfer is taking place. The webutil.cfg parameter transfer.appsrv.enabled must be set to true to use this function, and if the transfer.appsrv.accessControl parameter is also set to true, the upload target directory must be listed in the transfer.appsrv.write list. It is sensible to call the WebUtil_File_Transfer_IsASWritable function with the target filename before starting the upload to ensure that you will be able to write to this location on the application server.

Have you tried these other commands?

Why not throw a 'message;pause;' when the 'result' is 'false' instead of running the procedure again?

Hi,

Thanks David for the info. I was not yet try to use WebUtil_File_Transfer_IsASWritable since I succeed transferred the file using webutil_file_transfer.client_to_as_with_progress.

May I jump to conclusion that multiple transfers are not allow using webutil? So that I can say it is the limitation of the application. So that user should upload the file one by one.

Here in my webutil.cfr configuration:

transfer.appsrv.enabled=TRUE
transfer.appsrv.accessControl=FALSE

When I changed transfer.appsrv.accessControl=TRUE , I still got the same error.

If I throw 'message;pause;', how can I make sure that the previous transfer already success since that it return true already at the first transfer. Then, when should I resume the program.

Thanks & regards,
Dayang

Your code contains
  IF RESULT = true THEN
          message('done trnasfer');
          message('done trnasfer');
          RESULT := false;
          insert into ISR_ATT(att_id, inc_num, att_date, att_by, att_details, att_path) 
          values(att_id2, :ISR_MAIN.INC_NUM, sysdate, :parameter.P_LOGIN_USER, s_NEW_ATT, att_path2);
          commit;
          RETURN;
  ELSE
          PR_INS_ATT(NEW_ATT);

  END IF;
Why not have a 'pause' after the 'message' so that the user has to press 'enter' to go to the next file for transfer and why do you have "PR_INS_ATT(NEW_ATT);" hwne the transfer fails? Why not tell the user that the transfer failed?
