Unzip using PayloadZipBean

Hi,
I was looking to use PayloadZipBean module to unzip a zipped file with three text files inside.
From the receiver adapter Audit log files, I see that the PayloadZipBean,is unzipping all the three files(first file as main payload and rest of the two files as additional payloads), but while writing the files, it only writes one file with the Main Payload content and the file name from File Name Scheme parameter.
In module configuration, i gave name as zip.mode and value as unzip. Are there any other parameters where we can specify the names for additional files and also how do we extract other two files.
Already looked at 'SAP Note:965256 - XI 3.0 Adapter Framework Zip Module' where not much information is available on unzipping piece.
Thanks in advance.
Pradeep

I dont think you can use all the unzipped files as payloads. You might want to crate two scenarios where it writes all the unzipped files to disk (using receiver file adapter) then another file to X scenario as per your requirement.

Unzip using Payloadzipbean/file content conversion

Experts,
I have a scnario, I get a zip file with .gz extension, unzip it read th file using file adapter.
I am using Payloadzipbean module to unzip(zip.mode = unzip).
The problem is File adapter converting the zip file into xml and unzipping the file.
How do I force File adapter to unzip first and do content conversion.
thanks

Hi man.
How did you solve this. I have to pick up a zip file with a .txt file then I need to convert this file to xml with module MessageTransformBean but Im getting this error:
com.sap.aii.messaging.adapter.trans.TransformException: Error converting Message: 'sun.io.MalformedInputException'; nested exception caused by: sun.io.MalformedInputException
This is my structure
row (1..n)
>TRANSPORTES (1)
>ENTREGAS (1..n)
I have configured the module tag in this way:
AF_Modules/PayloadZipBean - zip
AF_Modules/MessageTransformBean - transform
CallSapAdapter - 0
zip - zip.mode - unzip
transform - Transform.Class - com.sap.aii.messaging.adapter.Conversion
transform - xml.ENTREGAS.endSeparator - 'nl'
transform - xml.ENTREGAS.fieldFixedLengths - 1,30
transform - xml.ENTREGAS.fieldNames - TIPO,NUM_ENTREGA
transform - xml.ENTREGAS.keyFieldValue - E
transform - xml.TRANSPORTES.endSeparator - 'nl'
transform - xml.TRANSPORTES.fieldFixedLengths - 1,30
transform - xml.TRANSPORTES.fieldNames - TIPO,NUM_TRANSPORTE
transform - xml.TRANSPORTES.keyFieldValue - T
transform - xml.keyFieldType - CaseSensitiveString
transform - Transform.ContentType - text/plain;charset=utf-8
transform - xml.conversionType - StructPlain2XML
transform - xml.documentName - MPrueba_Zip
transform - xml.documentNamespace - http:/XXXXXX.es/XXXX/sap/prueba
transform - xml.keyFieldName - TIPO
transform - xml.processFieldNames - fromConfiguration
transform - xml.recordsetName - row
transform - xml.recordsetStructure - TRANSPORTES,1,ENTREGAS,*
If I use only the MessageTransformBean directly from .txt everything works ok!!!
What am I doing wrong???
Thanks a lot!!!

Unzip file using PayloadZipBean in Sender FILE adapter

I am trying to unzip a flat file in Sender FILE adapter using PayloadZipBean.
I am getting mapping error. The problem is File adapter is reading data without unzipping. I am getting weird characters/data, so mapping error.
I searched all the blogs/ forum threads and help.sap.com, everywhere the focus is on zipping, not unzipping.
the file I have is with .gz extension, but I tried with .zip extension also.
Please help in resolving this issue.

Gopal,
GZIP and ZIP format are slightly different, as stated here :
"GZIP compresses only one file and does not have a header. ZIP contains header information about what files are contained in the file."
So I'm not sure the PayloadZipBean supports GZIP format ... Try to ungzip and then zip its content and see if the bean works for it

Error while using PayloadZipBean module

hi,
For sending the data in zipped format in JDBC Adapter i used "PayloadZipBean" module.
While Communication channel Monitoring at Receiver end I am getting this Error:--
"Message processing failed. Cause: com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Path to object does not exist at loacalejbs, the whole lookup name is localejbs/loacalejbs/AF_Modules/PayloadZipbean."**
Is there any need to write this module in adapter engine?

Controlling filenames using PayloadZipBean

Hello
I am struggling with names of the zipped files using payloadzipbean. The Scenario is as follows: we want to transfer an invoice including attachments to an external partner consisting of an xml message and one or more pdf files as attachments. the attachments are added to the message in an ABAP proxy on the sending R/3 system. The message is transferred to PI,where it si routed to an ftp communication channel. The xml message is zipped using the payloadzip bean and transferred to the external partner using ftp. The partner requires an approriate file extension to identify the types of files on the receiving side. Originally we managed this pay using the parameter zip.filenameKey and set it ContentType. The files inside the zip file are then named "untitled.xml" for the xml message and "untitled.pdf" for the attachments. However when there is more than one attachment the zipping of the file crashed, as both attachments have the same filename. We can fix this by adding an unique name to the attachment when it is attached to the proxy, and changing the zip.filenameKey to payloadName. The problem then is that the main payload file is called MainDocument without the .xml extension. I need to change the name of the payload or find another way to make the attachment filenames unique with zip.filenameKey set to ContentTyoe, Any suggestions ?
Eivind Langsæter

it is a bit tricky.
You might have to code a module to build the attachments and then use zipbean to zip it for you.
to set the name of the main document you can have a look into the sinppet of code below;
Vector_attachementFileName contains the name for the attachment
attachmentFileMainPayload has the data of the main payload
XMLPayload MainDocumentPayload = message.createXMLPayload();
        MainDocumentPayload.setContent(
          this.attachmentFileMainPayload.getBytes());
        message.setDocument(MainDocumentPayload);
        Audit.addAuditLogEntry(
          this.auditMKey,
          AuditLogStatus.SUCCESS,
          "Main Document Successfully Set");
        TextPayload txtpayload = message.getDocument();
        txtpayload.setContentType("text/plain");
        txtpayload.setName(
          this.Vector_attachementFileName
          .elementAt(lengthOfVector - 1)
          .toString());
        Audit.addAuditLogEntry(
          this.auditMKey,
          AuditLogStatus.SUCCESS,
          "File Created: " +
          this.Vector_attachementFileName
          .elementAt(lengthOfVector - 1)
          .toString());

How do I estimate time takes to Zip/Unzip using java.util.zip ?

If I am compressing files or uncompressing zips using java.util.zip is there a way for me to tell the user how long it should take or for perhaps displaying a progress monitor ?

For unzip use the ZipInputStream and pass it a CountingInputStream that keeps track ofr the number of bytes read from it (you write this). This CountingInputStream extends fileInputStream and as such can provide you with information about the total number of bytes available to be read and the number already read. This can give a crude idea of how much work has been done and how much work still needs to be done. It is inaccurate but should be good enoough for a progress bar
As for zipping use the ZipOutputStream and pass it blocks of information. Keep track of the number of blocks you have written and the number you still need to write.

Problem using payloadZipBean to unzip a file

I would like to run OS command to zip large amount of xml into one zip file before XI pick it up, then use unzip option in payloadZipBean to unzip all the xml files so XI can process them one by one from memory, this will reduce lots file I/O time.
But I am getting this warning message:
Warning Zip: message is empty or has no payload
But if I display this message in RWB, the only payload is this zip file.
Why the payloadZipBean is not unzipping this file as supposed to.

Did you check this blog

Zipping multiple Payloads to single Zipfile using payLoadZipBean

Dear Friends,
Can you help me in doing this sceanrios:
I'm trying to send multiple payloads from source (selection
of multiple payloads is done by checking Advance selection for
Source file) to PI, that inturn Zip all Payloads in to a single Zip FIle.
(note: payLoadZipBean is giving individual zip file for every single payload but I want it all in single Zip file)
And also can I zip, Additional Files sent through File Adapter,
as these are not considered as payloads. Plz correct me If I'm wrong.
I request you plz dont paste any links to blogs or forums.
I'm trying to create a module to perform this scenario,plz suggest me better answers, in case module develpment is not required.
Dear Stefen, I hope I will get a good answer from you soon.
And thanks for suggesting me to post a thread for this issue.
Thanks in advance
Praveen K Kurni

Dear Sameer,
I did studied the SAP note;
By using these parameters
Module Key: zip
Parameter name: zip.mode
Parameter value: zipAll
Module Key: zip
Parameter name: zip.filenameKey
Parameter value: contentType
Module zips all payloads as individual zipfiles
for ex:
my files are:
1. abc1.xml
2. abc2.xml
3. abc3.xml
module payLoadZipBean zips these payloads as
1. abc1.zip
2. abc2.zip
3. abc3.zip
But I want all the files to be zipped in to single zipped file:
let say abc_all.zip
Thanks any way

Zip Payload using PayloadZipBean Module Processor

Hi,
I'm using AF_Modules/PayloadZipBean in module processor of Receiver SOAP adapter to compress/zip the message payload. I've used the following module key parameters :
Parameter Name      Parameter Value
zip.Mode                  zipAll
zip.filenameKey        contentType
In the adapter engine monitoring from RWB I can see the following warning message :
Warning Zip: message is empty or has no payload
But I can see the msg payload from the RWB message monitor as expected.
Can anyone please throw any light on this issue?
Thanks in advance,
Dipankar

Hi Stefan,
Can you please explain what you meant by transfer-encoding gzip?
Actually the requirement is to receive xml message in compressed zipped format along with digital signature. As I understand using the ModuleProcessor which you mentioned in your blog I can send zipped message (using File Adapter I've actually achieved the result as mentioned in your blog. So thanks a lot for that!). But in file adapter I can't use digital signature. So how to satisfy both the requirements using a single adapter (and maybe using some module processors over it)?
Thanks for your help!

Problem in deleting Zip files unzipped using java.util.zip

I have a static methos for unzipping a zip file. after unzipping the file when i am trying to delete that file using File.delete()its not getting deleted. but when methods like exist(). canRead(), canWrite() methods are returning true what can be the possible problem ? i had closed all the streams after unzipping operation Please go through the following code.
public static boolean unzipZipFile(String dir_name, String zipFileName) {
try {
ZipFile zip = new ZipFile(zipFileName);
Enumeration entries = zip.entries();
while (entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry) entries.nextElement();
// got all the zip entries here
// now has to process all the files
// first all directories
// then all the files
if (entry.isDirectory()) {
// now the directories are created
File buf=new File(dir_name,entry.getName());
buf.mkdirs();
continue;
}// now got the dirs so process the files
entries = zip.entries();
while(entries.hasMoreElements()) {
// now to process the files
ZipEntry entry = (ZipEntry) entries.nextElement();
if (!entry.isDirectory()){
File buf=new File(dir_name,entry.getName());
copyInputStream(
zip.getInputStream(entry),
new BufferedOutputStream(
new FileOutputStream(buf)));}
} catch (IOException e) {
e.printStackTrace();
return false;
return true;
now i am trying to call this method to unzip a zip file
public static void main (String arg[]){
unzipZipFile("C:/temp","C:/tmp.zip");
java.io.File filer = new File("C:/tmp.zip");
System.out.println (filer.canRead());
System.out.println (filer.canWrite());
System.out.println (filer.delete());
Please tell me where my program is going wrong ?

Thanks .. the problem is solved... i was not closing the Zip file .. rather i was trying to close all the other streams that i used for IO operaion ... thanks a lot

Unzip using java itrerate XML

Hi all,
I want to unzip the file and extract the xml. To iterate over the xml file to get
the values and stored into tables.
so far i 'had done this,
To unzip the file,
final int BUFFER = 2048;
   try
   DomParserExample dom = new DomParserExample();
   BufferedOutputStream dest = null;
   String dir = "C:/New/employee1.zip";
   FileInputStream fis = new FileInputStream(dir);
   ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
   ZipEntry entry;
   while((entry = zis.getNextEntry()) != null)
      System.out.println("Entry = " + entry);
      dom.runExample(entry);   // To iterate the xml file
      System.out.println("Extracting: " +entry);
      int count;
      byte data[] = new byte[BUFFER];
      // write the files to the disk
      FileOutputStream fos = new FileOutputStream(entry.getName());
      dest = new BufferedOutputStream(fos, BUFFER);
      while ((count = zis.read(data, 0, BUFFER)) != -1) {
      dest.write(data, 0, count);
      dest.flush();
      dest.close();
   zis.close();
} catch(Exception e) {
   e.printStackTrace();
} The problem is, i want to pass the xml file to parse method. If anyone come across my
requirement. please give me a suggestions.

I have employee1.zip file inside it contains employee.xml. I want to Extract zip and pass the xml file
to another method. In that method to iterate logic should be written.
This entry will print "employee1/employee.xml"
     }{code
ZipEntry entry;
while((entry = zis.getNextEntry()) != null)
System.out.println("Entry = " + entry);
System.out.println("filename" + entry.getName());
dom.runExample(entry); // to pass entry
}public void runExample(ZipEntry entry) {
          System.out.println("Inside runExample");
          //parse the xml file and get the dom object
          parseXmlFile();
          //get each employee element and create a Employee object
          parseDocument();
          //Iterate through the list and print the data

Does Sender Mail Adapter support "PayloadZipBean" module

Hi everyone,
I have a scenario where, I get the email with an zip file as an attachment and I need to extract this file and send across. There is no mapping transformation done here, only I need to forward the attached file to the file server.
Zip file always contains 1 file and is a text file.
so Its an Email to File Scenario.
Can I send the zip file as it is without unzipping i.e., send the attachment as iit is to the file server?
If I want to unzip the file, does the module "PayloadZipBean" support in case of sender mail adapter. ?
Thanks,
Varun

Hi Varun,
Use "PayloadZipBean " Module at Receiver Communication Channel in the Module Tab Set the "Module Key.mode = unzip"
and Receiver communication Channel file should be "FileName.txt".
