File Adapter to read Zip file and send it as input to another webservice

Hi,
I have the below requirement:
1. A service will generate 3 attachments and place it in a particular directory.
2. SOA service has to pick those 3 files and send those files as input to another custom application which will email.
Design :
1. First SOA will create an archive file of those 3 attachements and then file adapter will poll for that zip file in that location and send that file as a whole to the custom application.
Query:
Now my question, is the above design feasible? If so, how to configure the file adapter to pass the file as input to that custom application?
Kindly do the needful
Thanks,
Priya

You can accomplish this via java embedding activity...Create a java embedding, which will create a zip file.. this java code is easy to implement..
You can also do away with un-necessary polling file adapter.. and you can use "Synchronous File Read" operation of File Adapter.. For Sync Read, you'll have to pass the zip file name, which you can easily fetch from java embedding activity..
Let me know, if this doesn't work.

File Adapter Not Reading Large Files

Dear Experts,
Enviornment :-
OS:-Linux
Jdeveloper:- 11.1.1.6
SOA:-11.1.1.6
Weblogic:-10.3.6
JDK:-SUN
Allocated RAM:-16GB
Currently we are in UAT Phase and now we are facingan issue in reading large file.Below is the Design details of the service
FileAdapter(Read)-->Bpel(Business login,Using FlowN)-->FileAdapter(Write CSV),JMS Adapter(AQ JMS topics)
In this case at the time of read itself we are facing issue. File adapter reading xml file but in receive activity receives input data as
xmlDocKey:1C135990067411E3BFA6B5087B629F9DI
I really couldn;t understand about the error. Even i tried reading as Opaque format and still end up with same error.
In order to make sure i have create mediator and tried reading the file, in case i was able to read file upto 15mb with out any error.Also i tried as "read as Attachment" in Bpel component and able to read the attachment upto 7 mb file, but this is hitting the performance side.
I request some one please let me know why the file adapter is giving XmlDOCKey rather then XMLContent to the inputvariable

Can you check your BPEL Properties in EM?
Go to Soa-infra > right Click > SOA Administration > BPEL properties
increase the Dispatcher Engine Thread = 10, Dispatcher Invoke Threads = 60 and Dispatcher Engine Threads to 90
Click on "More BPEL Configuration Properties"
Increase the DispatcherMaxRequestDepth from 600 to 1000.
Bounce the server and see if works..
Bounce the server and try again.
If this fails, try get a threshold by increasing the file size until it fails again.

File Adapter-Problem Reading Huge Files

Hi,
Here is the issue that i am facing
When reading huge file(csv file upto 6MB-8MB) the communication channel configured as File Adapter with a polling interval of 7 min(420 sec) is inconsistent in reading the complete file.Sometimes it reads the the complete file of 6 MB and sometimes it reads a part of the file say 3MB/6MB.Can this inconsistent behaviour be resolved.??
Your suggestions highly appreciated.
Regards
Pradeep

Hi Pradeep !
8mb is not a huge file for XI, I think it is a small one. Maybe your problem is not the size..please check if XI is not starting to read the file before it is completely written to the source folder. If you are creating that csv file from another application directly to the poll source directory of the XI scenario specified in the file adapter, and your poll interval is small, XI could start reading the file while you are still writing it. If this is the case, try to put the file with a different extension or filename than the specified in file adapter comm channel and when the file is completely written, rename it to its final filename and check if you are still having that misbehavior.
You can write the file to a temp directory and the move it to the XI directory once finished.

Matias.

Invoke File Adapter to read just once.

Hello all,
I want to invoke a partnerlink which is using File Adapter to poll for a file every fixed interval. I want the File adapter to read the file just once. In other words, what would be the behaviour of the File Adapter when i invoke it syn or asyn way? Would the file adapter read the file only once? Is there anyway to do this? I read in some post about it but i cannot find or recall the thread.
Thanks for your help.

I think I need to explain the scenario in order to give you some more idea as to why i need to poll file just once.
I am trying to create a schedular using Quartz and If i have this BPEL process scheduled to trigger at say some time, the process would keep on polling. Whereas i just need to poll when the trigger is fired that is once per every trigger fired.
Can anybody throw some ideas on this?

FILE ADAPTER NOT READING FILE.

HI, GUYS.
I'M USING A FILE ADAPTER TO READ A FILE THAT HAVE 4 REGISTERS AND EACH REGISTER ONLY HAS ONE FIELD THAT IS NUMBER TYPE.
I CREATE THE FILE ADAPTER, AND I LET BPEL TO CREATE THE SCHEMA. THE IDE CALLS THES FIELD "C1". I ALSO CONFIGURE THAT THE FILE THAT MUST RAD IS THE PATTERN "*.TXT" AND EVERY 5 SECONDS.
THEN A CREATE A RECEIVE ACTIVITY THAT RECEIVES WHAT WAS READ FROM THE FILE ADAPTER IN A VARIABLE.
THEN I CREATE AN ASSIGN ACTIVITY AND I ASSIGN THE VALUE FROM THE RECEIVE ACTIVITY VARIABLE TO A NUMBER VARIABLE THAT IS THE INPUT OF A WEB SERVICE.
THEN I DEPLOY THE BPEL, AND I INITIATE IT, BUT I GOT AN ERROR THAT SAYS THAT THE FIELD "C1" IS EMPTY. SO LOOKS LIKE THE FILE ADAPTER IS NOT READING THE FILE. I WOULD THANK ANY HELP THAT YOU CAN BRING ME.

caps off
You're sure the interface of the fileadapter (client partnerlink) is the same as your data-file which needs to be picked up?
can you paste the content of the file and the content of the xsd of the process.

Reading .ZIP files using File Adapter

Hi,
I am using BPEL File Adapter to read files. The files to be read are XML files which are in zipped format.
so how should I read these .zip files and extract the XML files from that.
Thanks
/Kiran.

If the xml files are all in the same directory (not in any directory structure relative to the parent directory), you can do something like this.
- create a bpel process to read the zip files as it comes into the directory]
- Have a file adapter inbound for the receive
- Call windows .bat command within the bpel process to run an unzip command on that directory
- Have another bpel process that reads *.xml files and this will get kicked off.
There are so many ways of solving this: like having a cron job to unzip the files coming in etc. But, if you have a directory structure for these XML files and if the structure is dynamic, it is difficult to configure the file adapter for that.

XI Sender file adapter - How to process data and control files.

Hello all,
I have the following requirement to fulfill: I am using an FTP client (XI Sender file adapter) to retrieve data from an FTP site. To make sure I am not picking up a data file that is currently being written to, 2 files are actually present on the FTP site (for each data file):
1. abc.ctrl (control file with no data in it. Indicates that the data file has been completely written).
2. abc.dat (actual data file).
I want the file/ftp connector in XI to retrieve the data file (abc.dat) only if the control file (abc.ctrl) is present. After the processing of the data file is finished, both files (.dat and .ctrl) should be deleted.
Is there an elegant and robust way to accomplish this?
Thanks for your help.

Hi Yves,
in my opinion there's no problem with files currently being written in combination with a polling file adapter because the final file name should be available only when the file is transferred completely. I'm using different file sender adapters very often and never had any problems. After picking up the files I move them to the corresponding archive folders mentioned in the adapters so that a second processing cannot occur.
Regards
Ralph

Sener file adapter has read/pick the files first in first out method.

HI
In my Interface I am Using Sender as File adapter. As per my requirement Sender file adapter has to read the file from file directory. This directory having 1000u2019s of files with some files are same name (time stamp is different) and some files are different name here file adapter has to pick the file with mentioned name in File sender adapter like ZMPSMSGSTATUSMST-.xml .
But source file name is like <TABLENAME>-<TIME_STAMP>.XML (ZMPSWRKFLOWHIST-20090527-150522-628) in file directory.
The file adapter in XI will poll to this directory and picks the file in first- in first-out by sorting according to timestamp.
To do this configuration what I have to do in sender file adapter please give me your valuable inputs.

HI Abhi,
Thank you for your spot replay.
I tested now but i am geting below error.
Putting message into send queue failed, due to: com.sap.aii.af.ra.ms.api.DuplicateMessageException: Message ID f4ca4f86-9c5d-4bdd-1fb1-a6bd7cda99a8(OUTBOUND) already exists in database: com.sap.sql.DuplicateKeyException: [NWMss][SQLServer JDBC Driver][SQLServer]Violation of PRIMARY KEY constraint 'PK__XI_AF_MSG__491A1D0B'. Cannot insert duplicate key in object 'dbo.XI_AF_MSG'..
Could not archive file 'E:\file\in\ZMPSMSGSTATUSMST-20090527-150522-628.xml' after processing
but i am able to see this file in Archive foleder. once file is archivied sucessfully the same file is delted from source directory?
I given processing parametes queue name is TEST.

Sender File adapter not picking the file ABCD.PRN extension file

Hi
Am doing File to Abap Proxy scenario. My source will be in text format of fixed length of fileds 7.
My souce file will be generated by a third party machine with the extension EEE150809.PRN. In my scenario my file adapter should pick the file and update the same in ECC via a Proxy.
I have configured the Sender File adapter with Message Protocol - Content Conversion but file adapter is not picking the file. I have checked the Communication channel and status is fine. But the same Communication Channel works for .XML file.
What are the parameters that I have to consider with the file extension .PRN using File adapter?
Thanks.
S.

Hi Swarna,
You dont need to worry about the extension when picking the file. You can try using EEE* so that is picks all the files starting with EEE. If you have the fixed name then you can try giving EEE150809.*. Also EEE150809.PRN should not have any issue. Try to see in sender commu ication cahnnel for anyerrors. Probably there might be some network issues or authorisation issues. If you are reading with NFS then ask them to give necessary permissions. If you are reading through FTP check the user id and pwd you are using.

Sender File Adapter stop processing all files

Hello all,
the file adapter pick up all files in the directory by default.
if a large number of files are in the directory then this could slow down the pi processing.
is there any way to process only one file per polling??
regards

I do not have any proble if you have got the answer. BUT this blog says how to exclude the other files from the same folder.
Your Case: For example, Your Sender CC wants to pick up file ABC.txt from /xyz dir, now suppose there are 10 thousand files of same name in the dir and you want ABC.txt should be picked up one by one, So how this blog is going to help you. Can you Plz explain to me and others too?
@Sachin may be you can throw some light on this... may be I am missing something.

I have an async bpel process.
I have to read file name in this process... so i have used file adapter sync read operation.
How can we get the file name with out payload using sync read.
For normal read (Inbound Spec)we have UseHeaders="true" property.
Is there any property for sync read to read the file name.
Please help me

Alternative APIs for reading Zip files?

Hi all.
At the moment, our application handles zip files by copying the zip file to the temp directory and then creating a new ZipFile. However, the larger the zip file we encounter, the slower this copy becomes. We also need random access to the Zip file, so the usual workaround of using ZipInputStream is also slow, although slightly faster for random access than copying the entire file.
I raised a bug requesting a better constructor for ZipFile, but it was turned down as they seemed to think I didn't want random access.
But does anyone know of any alternative APIs which can access Zip files in a more random access fashion? I've discovered a few other alternative implementations of ZipFile, but all of them so far have had this issue of requiring a File.

intensive. I am basically searching through zip
files to find a file and then taking that inputstream
for processing. I am basically looping through the
zip file until i match the filename....pretty crazy.I think it is pretty I/O intensive...hence slower
to see what I can do to increase performance. I am
using the following parameters:
-Xms512m -Xmx1024M -Xss16M -XX:ThreadStackSize=256
-XX:MaxPermSize=256m
Parameters look ok. I am not sure what -XX:ThreadStackSize will do as -Xss also sets the stack size? you can also try to pass -server and keep both Xms and Xmx to 1024 and see if it brings any improvement.
