Empty line handling in sender fileadapter FCC

Hi Al,
How do we ignore empty lines in the fixed length file by using FCC?
In my input file,i would be having emply lines at last and as per my curect FCC configurations,it is reading that emplty line also and due to this,message got failed in message mapping.How do we ignore this in sender file adapter?
I do not want to change any mapping condition.

Hi Rajesh,
Just a short in the dark . There is a parameter by the name of NameA.keepIncompleteFields
This parameter is only evaluated if you enter a value for NameA.fieldFixedLengths.
○ If you enter NO and the last field found in the structure is shorter than specified in NameA.fieldFixedLengths, processing is terminated with a corresponding error message.This is the default.
○ If you enter YES, the last field found in the inbound structure is transferred to the outbound structure, even if it is shorter than specified in NameA.fieldFixedLengths.
Caution
You use this parameter to control the behavior of the conversion routine for the last field in a structure.
Use the NameA.missingLastFields parameter to define the behavior at runtime when the structure contains less fields or no fields (as in your case a blank line) in total that specified in NameA.fieldFixedLengths.

Removing the empty line during Receiver FCC!

Hi, Guys,
I used file content conversion in receive FCC. My data type is like this:
<TextFromSAP_DT>
<FileName>
<FileName>abc.txt</FileName>
</FileName>
<Record>
<TEXT>dasfafaf</TEXT>
</Record>
<Record>
<TEXT>qqqqqqqq</TEXT>
</Record>
<Record>
<TEXT>fgfffff</TEXT>
</Record>
</TextFromSAP_DT>
I need to get file name from <FileName> and output a flat file with the value in <TEXT>. But I always got an empty line at the file beginning. And I tried to move <FileName> to the end. And I got an empty line at the file end. My custom said they are having trouble to read the file with the empty line no matter it is in the beginning or end.
I followed sample as link below but does not work.
https://wiki.sdn.sap.com/wiki/display/profile/2007/07/30/Removing%20the%20empty%20line%20during%20Receiver%20FCC!
Does any body can give a help?
Thanks a lot!

Hi Yang,
You create the value udf GetFileName with one input value say a. Add this code:
Imports: java.*;
Add this code:
//write your code here
DynamicConfiguration conf = (DynamicConfiguration)container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http:" + "/" + "/" + "sap.com/xi/XI/System/File", "FileName");
conf.put(key, a);
return "";
Map like this:
FileName --> GetFileName(udf) --> target_mt
Map other fields like:
Record --> Record
TEXT ---> TEXT
Save it and activate it. When you test in mapping you will get an error so dont worry. I go the error like:
RuntimeException in Message-Mapping transformation: Runtime exception during processing target field mapping /ns0:Target_MT. The message is: Exception:[java.lang.NullPointerException] in class com.sap.xi.tf._TestFileName_ method file1$[abc.txt, com.sap.aii.mappingtool.tf3.rt.Context@32dcebf1]
Dont worry about this activate and do the rest of the configuration.
In your receiver communication channel for file name put as FileName and check the file name in adapter specific message attributes. Then test it and it should work and you will get the file with file name abc.txt. I tested the whole end to end scenario and I am getting the file name abc.txt and the output what you want. If you still could not get it send me a m ail to my i d from my business card. I will send you the screen shots.

Issue with Sender File FCC

Hi Experts,
I have an issue with Sender File FCC Adapter. The file being picked is of type TXT and it is tab seperated. The first line contains the field names and from next line onwards we have values for those fields.
The field names and field values are tab seperated. Even inserting a single letter in some field value manually disrupts the whole setup & alignment of the TXT file and the Sender File CC is unable to pick up the file from the shared folder. If the first file is errorenous and after that a correct TXT file is posted, it fails to pick up the correct file as it is trying to pick the errorenous file first.
The Error thrown is :
"Conversion of file content to XML failed at position 0: java.lang.Exception: ERROR converting document line no. 2 according to structure 'ABCD':java.lang.Exception: ERROR in configuration / structure 'ABCD.': More elements in file csv structure than field names specified!"
I have two questions:
1. Is there a way to handle such a scenario? For e.g., the errornous TXT file gets picked but throws error in PI.
2. Is there an alternative that the sender FCC channel picks up the correct files and filter out the errorneous ones ? ?
Thanks,
Arkesh

Hi Arkesh,
I think you are passing more number of fields than expected. Please check paramters defined and send the data accordingly.
In the processing parameters tab of sender file adapter, you have an option called Archive faulty source files, below to that you would have option to enter the " Directory for Archiving files with Errors".
I hope this helps you....
Thanks,

Empty Lines are not taking

Hi all,
    I am doing the scenarios File-File with FCC. My source file is as follows. But it is not picking the Empty lines which are there in the source file
So My structure as follows:
MT_BNK01 1..1
RECORD 0..Unbound
--Record_data 0..Unbound
So in the Sender CC i written as follows
Recordset Structure:: RECORD,1
FCC paramtetrs as follows
RECORD.fieldNames     RECORD_DATA
RECORD.fieldSeparator     '0x0D''nl'
ignoreRecordsetName     true
What i need to do extra to capture the empty lines from my source.
Thanks in Advance,
Best Regards,
Vijay

Hi Rajesh,
I did that one also. There is no effect. Currently i am using all the these FCC paramters:
RECORD.fieldNames     RECORD_DATA
RECORD.fieldSeparator     '0x0D''nl'
RECORD.endSeparator     '0x0D''0x0A'
ignoreRecordsetName     true
RECORD.fieldContentFormatting     nothing
RECORD.enclosureConversion     YES
The problem here , we given the 'nl' as the fieldSeparator. So if 2 consucutive 'nl' comes then there no value between them so it is suppressing. How to overcome this.
Warm Regards,
Vijay

How to get rid of empty lines in a file?

How can read a file "text.txt", delete all the empty lines and restore it to same filename "text.txt" without using a temporary file?

Ages ago I ruined an 8" floppy disk drive by doing something similar to
this: let b1 b2 ... bn nl be a series of blanks followed by a newline
character (nl) and let c1 ... cm be a sequence of other characters. Let
the total relevant sequence be:
b1 b2 ... bn nl c1 ... cm
Reverse the entire sequence: cm ... c1 nl bn ... b2 b1 and then
reverse the first m bytes: c1 cm nl bn ... b2 b1. Now repeat the entire
thing for the sequence c1 ... cm by checking for more blank lines in it.
After this has all finished, simply truncate the file.
The advantage of this method was that I only needed to be able to swap
two bytes in a file; the disadvantage was that the floppy disk drive
couldn't handle it ;-)
kind regards,
Jos

Receiver File adapter - 'Empty Message Handling' option to ignore not worki

Hi,
I am trying to create the Files in receiver based on condition.But I am gettiung error in communication channel when there is no payload. Receiver I am usuing FCC and processing tab I selected -'Empty Message Handling' option to ignore .
one source -> Target 1 (0..1 occurance in signature tab changed, message mapping and operation mapping)
and Target 2 (0..1 occurance in signature tab changed)
and I put the message type level condition. While creating first message If did not create the Message type in my maaping still my Receiver File communication channel is giving error. even thow I my receiver interface occurance is 0..1
Right now I am in PI7.1 and SP7 is the bug for support pack do I am missing any thing. and do I need to upgrade any nwe patch. appreciate your help.
Regards,
Venu.

Hi,
here is the my requirment one source -> two target interfacess (0..1)
If u have 2 target interfaces,then this is not suffice..... u should make it as 0..unbounded both in operation mapping and message mapping.
But based on ur requirements posted above i guess u have only one inbound interface at a time based on some conditions....
But,
<messages>
<messages1>
based on condition first message type not created in mapping.
<messgaes2>
The error u r getting is because.... u want only one interface in target at a time....
Then u should not generate Message1 also in the target.
So avoid mapping to message1 if u want only message2.
If both message1 and message2 are created in target means... it is triggering for two interfaces.... so avoid one message1 or message2... based on some conditions u have..
Still nt solved do post...

How can you avoid the empty line?

hi all,
i looked around quite a bit and didn't found an answer to this very common problem.
i used this blog:
Solution to the problem encountered using Variable Substitution with XI-SP12
for using a dynamic filename.
the problem i get is the file adapter create a empty line instead of the FILENODE which i need to be suppressed and not written to the file.
is it possible?
regards,
roi grosfeld

Hi,
Well thats good question. you can't test it in test tab of mapping.
It will give you exception like something below
RuntimeException in Message-Mapping transformation: Runtime exception
Here you can create the file name in Mapping either by using various APIs as well as Sender side filed values and can pass to the UDF that you will create for dynamic filename.
File with same name will be created. This is specific to DynamicConfiguration class which deals with the values at runtime.
Thanks

Problem with „Empty-File Handling" in PI 7.11

Hi,
Iu2019m working in PI 7.11 with file adapter, Sender CC, option: Empty-File Handling: Process Empty Files.
What I want to do is giving target file the system-date, if the source file is empty.
But I always get a mapping error in RTWB: Premature end of file.
It seems that the payload is empty.
Any idea?
Thanks a lot in advance!
Rene Dong
Edited by: Rene Dong on Aug 31, 2010 4:20 PM

What I want to do is giving target file the system-date, if the source file is empty.
The error you are getting makes sense. You should do a check in the mapping, if the payload is empty then use brute force to pass the system date.

Empty File Handling in xLink adapter

Helloo Experts
I am doing a scenario, which creates an empty file(when some mapping condition doesnt satisfy).
I dont want to write this empty file in the target directory.
This can be handled if a file adapter is used, but I am using a SOAP AXIS adapter, so I dont know how to handle this here.
I alaso tried using the StrictXml2PlainBean to avoid the creation, it creates 0 documents and a 0kb empty file.
Can anyone please let me know how this can be solved????
Also if some one has done this empty file handling in J2SE file adapter...can you tell how it was done.
Thanks a lot!!!!!!
Regards
Shobha

Hi Gabriel,
You can write a simple script to copy a file from source folder to target in case the fiel size is ZERO bytes. The script will not copy the file if the filesize is more than zero bytes, This will be processed normally by PI server. You can call the script from sender communication channel parameter : "RUN OS command before message processing". Could you please specify the Operating System (OS) you are using in your PI server.

Empty File Handling : Do Not Create Message

Hi,
I have set this option in Sender CC - file.
Parameters --> Processing.
I dont want to pass file to reciever , when file is empty.
Will the above option "Do Not Create Message" do the trick.
OR do i need to choose something else??
-santosh.

Santosh,
Yes. The trick will work for empty file handling.
When your incoming file is empty then will be no xml message posted to IE and hence receiver will not get any message.
FYI: Also you can use skip empty files which will do the same but here the files will remain in your source directory.

Prasanthi.

Hi,
I think we could handle this with may be usage of Advanced UDF in Graphical mapping only.
Here as per the condition you are deleting the particular record but unknowingly blank value i.e. " " is getting passed so on target side blank node is created for this record.
You need to just avoid this blank Node.
If you can share the logic you have applied for Middle field as well the source and target structure I will be able to try the UDF code..based on it
Thanks

Empty lines at the end of the payload generated in FTP server

Hi All,
I am facing an issue in one of the use cases that I am trying to implement.
I am getting a purchase order from one of the trading partners through Oracle B2B.
B2B forwards this B2BM (B2B message ) to AIAB2BInterface. From AIAB2BInterface my BPEL process gets invoked, which in turn invokes the AdapterComposite which has a FTP adapter that writes the purchase order to a FTP server. PFB the end to end flow.
PurchaseOrder from ABC trading pertner--> Oracle B2B --> AIAB2BInterface --> TestInputProvABCS --> TestInputAdapter -> Host trading partner picks up the file from FTP location
In the ProvABCS I retrieve the actual payload from the B2BM and convert it into a string using ora:getContentasString. I am then invoking the adapter composite and sending the string as the input to FTP adapter. At the adapter composite I use a simple native schema (for validation of the input string) which has only one element PO_Info of the type string. But when the file gets generated in the FTP server there are empty lines and junk characters at the end of the file.
Need some advice on this. Why are the empty lines coming in the end of the file? Please help!
Thanks

OK, I cannot figure out a way to modify the JTable (in an extended class) directly.
So, what I did was to add a wrapper around the TreeTableModel which shows an empty row at the end.
For those of you who are in a similar situation, the methods that I had to modify are
public boolean isCellEditable(Object node, int column);
public int getIndexOfChild(Object parent, Object child);
public int getChildCount(Object node);
public Object getChild(Object node, int i);
These other methods are required if you are using a TreeTable instead of just a table (see http://java.sun.com/products/jfc/tsc/articles/treetable2/index.html)
public Object getValueAt(Object node, int row, int column);
public Object getValueAt(Object node, int row, String columnName);
public void setValueAt(Object node, int row, int column, Object newValue);
public void setValueAt(Object node, int row, String columnName, Object newValue);
The signature of above methods is slightly different than the ones at: http://java.sun.com/products/jfc/tsc/articles/treetable2/src/TreeTableModel.java
This is due to the fact that, if you want to display the serial no. (as in row number), then getValue() can just return the row number. IndexedTreeTableModel is another wrapper around the TreeTableModel which can add an extra column to display the serial number.

Extra empty lines in java code

Hello
I am experiencing a strange behaviour of SJSC 2.1 (Windows XP) after insttalling the last performance fix
When manipulating components in a page, the .java file gets corrupted. An extra empty line is including after each line. Code still compiles but obviously the code becomes unreadable. This happens if you add a new component to the page o double-click in a component (to edit the action or valuechange methods
Editing-only (in the java window) works ok.
An additional problem found. International characters are not handled properly anymore by the design editor (or the properties window). Changes to them are translated to question marks in the JSP. Only wokaround is to directly edit the JSP
All this happened just after installing the hotfix.

I had the same problem, and pointed out to the Creator, who were able to reproduce it. So, they know about it now.
A very undesirable effect of this problem is that as the Java files grows in size, JSC becomes very slow, and can sometimes hang.
Also, I've noticed that this problem happens only with JSC1 created pages, not with JSC2 pages.
My workaround is the following:
1). Download and install the text editor - TextPad
2. Go to the folder containing the java files with the extra lines, select them all, and open with TextPad.
3). Fix the extra line problem with the following regex:
^[[:space:]]*\n
The above regular expression, will take care of the extra lines.
4). Do a search and replace all for all active documents, and save and close.
But obviously, this is a serious problem, and I urge the Creator team to please fix it at the earliest, so as not to cause further confusion and loss of time and effort!

Haroon

TS3276 I cannot get my outgoing SMTP server togo "On-Line" and cannot send out emails.

I cannot get my outgoing SMTP server togo "On-Line" and cannot send out emails.

I had this problem too but I fixed it today.
Go to the mail menu preferences.
Click on account in question.
Select the outgoing SMTP mail server (the one offline), this has a drop down list, click on the edit server list.
Click on the advanced button.
Make sure use default port is checked.
Make sure SSL is unchecked (unless your provider requires it, mine does not work with it checked).
Have authentication set to password.
User name should be your email address for that account.
Make sure correct password is entered (for some strange reason my password box was blank on this account).
Push the ok button.
For me the SSL box was checked and the password was missing. This is strange to me considering I have unchecked the SSL Box on the mail preference advance page. Also, I went through the complete set up account when I first created the account, why was my outgoing server password box empty?
I hope this helps.
