SOAP attachment - module development?

Hi,
I have an IDOC -> SOAP scenario where I have to call a webservice that uses SOAP attachment.
Example:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ueb="IBrokerInterface">
 <soapenv:Header/>
 <soapenv:Body>
 <ueb:TEBIBrokerInterface_PublishWS>
 <aClientId>TEST</aClientId>
 <aMessage>cid:file.xml</aMessage>
 <aDuplicates>0</aDuplicates>
 </ueb:TEBIBrokerInterface_PublishWS>
 </soapenv:Body>
</soapenv:Envelope>
The "file.xml" has to be a SOAP attachment.
If I use a SOAP receiver channel how do I get the IDOC payload moved into a SOAP attachment and still keep the SOAP envelope?
Can this only be done with module development?
Thanks Rasmus

Hi Rasmus,
You cannot create an attachment in mapping.
In PI 7.1 there will be a Java Mapping API for working with attachments, but the code will be similar to an adapter module. It will not be possible with XSLT.

PI 7.1 Adapter Module Development - Identify SOAP Fault Message

Hi Experts,
here's a PI 7.1 Adapter Module Development issue I hope you can help me to resolve. It's about identifying SOAP fault messages.

Scenario at a glance:
Adapter Modules placed in the modules chain at request and response time in a synchronous Scenario:
- Request: SOAP Axis to RFC 
- Response and Fault Response: RFC to SOAP Axis

The issue is how to identify SOAP fault message in SOAP Axis Adapter Module in the response message:
The client gets SOAP fault messages like the follwong one:
 <SOAP:Body>
 <SOAP:Fault>
 <faultcode>SOAP:Server</faultcode>
 <faultstring>Server Error</faultstring>
 <detail>
 <ns1:exception xmlns:ns1="http://typen.geschaeftsstelle.pab.barmer.de">
 <ns1:errortext>bla bla bla ...</ns1:errortext>
 </ns1:exception>
 </detail>
 </SOAP:Fault>
 </SOAP:Body>


But when trying to access the tags faultcode and/or faultstring in the adapter module via xPath expressions I do not get them. Obviously the SOAP Fault tags are built AFTER the adapter module has been passed. So my question is:
How can I clearly/uniquely detect a SOAP fault response message (and distinguish it from a "normal" response message) in my SOAP Axis Adapter Module?

I tried it the following way:


// Check Message Payload for SOAP Fault Message via xPath expressions
...
// SOAP Fault Code
zv_xPression = zc_constXPattern.replaceFirst("&", "faultcode");
zv_soapFaultCode = XPathAPI.eval(zv_doc, (String) zv_xPression).toString();
// SOAP Fault String
zv_xPression = zc_constXPattern.replaceFirst("&", "faultstring");
zv_soapFaultString = XPathAPI.eval(zv_doc, (String) zv_xPression).toString();
// check for SOAP Fault Message
if (zv_soapFaultCode.equals("") && zv_soapFaultString.equals("")) {
 // Create Audit Log entry - NOT a SOAP Fault Message
 zv_msgText = zc_constModuleName + " 0190: xPath - OK! This message is NOT a SOAP Fault Message";
 zv_audit.addAuditLogEntry(zv_msgKey, AuditLogStatus.SUCCESS, zv_msgText);
 zv_faultCheck = false;
}
else {
 ...
 // Create Audit Log entry - SOAP Fault Message
 zv_msgText = zc_constModuleName 
 + " 0200: xPath - this message is a SOAP Fault Message. " 
 + " - Faultcode is: " + zv_soapFaultCode 
 + " - Faultstring is: " + zv_soapFaultString; 
 zv_audit.addAuditLogEntry(zv_msgKey, AuditLogStatus.ERROR, zv_msgText);
 ...
}
...

But zv_soapFaultCode and zv_soapFaultString are always empty (with other payload tags this coding works fine).

Any ideas? 
Thanx very much in advance!
Regards,
Volker

Hi Alex!
Like already mentioned I solved my problem by identifying the SOAP exception with the messageClass attribute of the PI message header. Acess code:
try {
String zv_msgClass = zv_piMsg.getMessageClass().toString();
} catch (Exception e) {
zv_msgText = zc_constModuleName
+ " E0110: Message processing terminated."
+ " Reason: Error while getting MessageClass "
+ zv_dataSource
+ e;
// create trace and audit log entry (severity ERROR) for exception
zv_location.errorT(ZV_SIGNATURE, zv_msgText);
zv_audit.addAuditLogEntry(zv_msgKey, AuditLogStatus.ERROR, zv_msgText);
ModuleException me = new ModuleException(e);
zv_location.throwing(ZV_SIGNATURE, me);
e.printStackTrace();
throw me;
} // end of try-catch-block
But I do not think this will solve your problem. I am almost sure, that something in your Axis configuration is wrong/missing. If a handler cannot be instatiated then it really may be missing. Have a look at defaultTrace.trc. Maybe you will find more suitable information about the root cause of your problem. Also have a look at NWA under software components and/or application modules if you can find/see your modules.
But there is a general issue when trying to catch PI fault messages. If e.g. the requestor tries to login with wrong userid/pasword, then you will have no chance to catch this kind of error - at least as far as I know. Because in this very early stage of PI message processing no module is called.
One last question: Did you develop your own Adapter or just an adapter module? In the first case: Is your adapter started and healthy? Have a look at RWB -> communication channel monitoring.

Convert SOAP Attachment into SOAP Body

Hi,
I am getting the response from external system through SOAP attachment, how to convert it into soap body.
Is there any other alternative apart from PayloadSwapBean, if not, let me know the steps of the same.
Regards,
B.Anandh

Hi Krish,
It is not possible to use adapter module (Custom or standard) in SOAP sender adapter and this thing is clearly mentioned in Help.sap.
But you can use axis adapter to use module (Axis adapter is extention to soap adapter). It provides modules which are flexible enough to fulfil your requirment.
If you are using Receiver SOAP adapter then youn can either have PayloadSwipeBean or your own adapter module. And it is possible to convert the attachment to the payload using custom module.(I have Done this)
There is method available getAttachment() of type. Just Check API.
Thanks

"Content is not allowed in prolog" with SOAP Attachment

I'm writing an application using SAAJ that sends a soap message to a servlet which responds with some information, including HTML which the client application will display. The HTML has to go into a SOAP attachment so the tags won't get confused with XML.
I had the whole thing working with plain text sending within a normal node, and I only switched a few lines to make that text an attachment with HTML instead, but now I'm getting the exception "Content is not allowed in prolog" on the Client side when it tries to create the envelope from the SOAPMessage.
Code for building answering SOAPMessage with attachment (Servlet to Client)
 public static SOAPMessage buildXML(Message newMessage){
 SOAPMessage msg = null;
 try {
 MessageFactory msgFactory = MessageFactory.newInstance();
 msg = msgFactory.createMessage();
 // Create an envelope in the message
 SOAPEnvelope envelope = msg.getSOAPPart().getEnvelope();
 msg.setProperty(SOAPMessage.WRITE_XML_DECLARATION, "true");
 msg.setProperty(SOAPMessage.CHARACTER_SET_ENCODING, "UTF-8");
 //Get hold of the the body
 SOAPBody body = envelope.getBody();
 SOAPElement soap_message = body.addChildElement("MESSAGE");
 if (newMessage.message_type != null){
 SOAPElement soap_message_type = soap_message.addChildElement("MESSAGETYPE");
 soap_message_type.addTextNode(newMessage.message_type);
 if (newMessage.questionID != 0){
 SOAPElement soap_questionID = soap_message.addChildElement("QUESTIONID");
 soap_questionID.addTextNode("" + newMessage.questionID);
 if (newMessage.username != null){
 SOAPElement soap_username = soap_message.addChildElement("USERNAME");
 soap_username.addTextNode(newMessage.username);
 if (newMessage.password != null){
 SOAPElement soap_password = soap_message.addChildElement("PASSWORD");
 soap_password.addTextNode(newMessage.password);
 if (newMessage.message_text != null){
 AttachmentPart soap_message_text = msg.createAttachmentPart("<html><body>" + newMessage.message_text + "</body></html>", "text/html");
 soap_message_text.setContentId("MESSAGETEXT");
 msg.addAttachmentPart(soap_message_text);
 //SOAPElement soap_message_text = soap_message.addChildElement("MESSAGETEXT");
 //soap_message_text.addTextNode(newMessage.message_text);
 if (newMessage.sampleString != null){
 SOAPElement soap_password = soap_message.addChildElement("SAMPLESTRING");
 soap_password.addTextNode(newMessage.sampleString);
 SOAPElement tmpEl;
 for (int i=0; i<newMessage.numArrayUsed; i++){
 tmpEl = soap_message.addChildElement("SAMPLEINT");
 tmpEl.addTextNode("" + newMessage.sampleInt);
 msg.saveChanges();
 } catch (Exception e) {
 e.printStackTrace();
 return msg;
You can see in the area where it adds MESSAGETEXT there are two clients commented out which work. The three lines above it are what changed to make it an attachment instead.
Code in Client for recieving reply from Servlet
SOAPMessage reply = connection.call(soap_msg, endpoint);
System.out.println("\nReceived reply from: " + endpoint);
reply.writeTo(System.out);
System.out.println("");
reply_msg = ProcessXML.parse(reply);This is the console output:

I suppose I should also include the bit where the Servlet actually SENDs the resulting SOAPMessage

// try to send it
try {
 response.setContentType("text/xml");
 msg.writeTo(response.getOutputStream());

ModuleData.getPrincipalData returns null in the adapter module development

Hi gurus,
i am doing a test on the adapter module development following an article written by William Li:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0ac06cf-6ee2-2c10-df98-e17430ca5949?QuickLink=index&overridelayout=true
my problem is after the EJB has been deployed, it seems that the return of inputModuleData.getPrincipalData() is always null which makes the program can not get the xml payload from the framework.
the main process of the example has been simplified like this:
     public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          Object           obj = null;
          try {
          obj = inputModuleData.getPrincipalData();
          Message     msg1 = (Message) obj;
                XMLPayload xmlpayload = msg1.getDocument();}
          catch (Exception e) {
               ModuleException me = new ModuleException(e);
               throw me;
          return inputModuleData;
after deployed, i get the following error in the adapter monitor of RWB: (my JNDI is testtest)
17.02.2012 17:13:44.643 Information Send binary file "test8.xml" from FTP server "10.18.48.150:/encrypt_test/", size 206 bytes with QoS EO

whereas if the code has been changed like this:
     public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          Object           obj = null;
          try {
               obj = inputModuleData.getPrincipalData();
               Message     msg1 = (Message) obj;
               if (obj != null )
                    XMLPayload xmlpayload = msg1.getDocument();
          catch (Exception e) {
               ModuleException me = new ModuleException(e);
               throw me;
          return inputModuleData;
the file can be read by the file adapter.
i just quite confused that why the return of the getPrincipalData() is null? where is the problem? thanks
Edited by: Stephen Xue on Feb 17, 2012 5:22 AM

I'm gonna reply to myself here. I changed the processing sequence of the adapter modules in the in the FileSender channel so that my module comes first then CallSapAdapter. Then getPrincipalData() contains the message.
Hope this helps someone else.

Unique Problem: Returning SOAP+ Attachment using a class based webservice

Hi everyone,
Im trying to return a Soap+ attachment response back using the following:
attachDoc(byte[] bdoc, String sTransactionNumber,
String sRequestedType)
Where byte[] is the attachment and the 2 string parameters are soap message contents.
The attachment is attached successfully to the message and i can send a response back to the clients console using :
message.writeTo(System.out);
My problem is that i dont know how to return this soapmessage+attachment back to the client.
Ive tried using the return type of the method as :
public SOAPMessage attachDoc(byte[] bdoc, String sTransactionNumber,
String sRequestedType)
but i cant return a SOAPMessage return type in axis.
Does anyone have any clues how i should sort this out so that the client gets the SOAPMessage and attachment when the method is called ?
Please help :S
Thanks,

I dunno if this is what you asked for....
Hope this helps a bit
You may want to check this link out
http://www-unix.globus.org/mail_archive/discuss/2007/02/msg00037.html
MessageContext msgContext = MessageContext.getCurrentContext();
File file = new File("filename.txt");
org.apache.axis.attachments.AttachmentPart replyPart=
new org.apache.axis.attachments.AttachmentPart(new DataHandler(new
FileDataSource(file)));
Message rspMsg= msgContext.getResponseMessage();
rspMsg.addAttachmentPart(replyPart);
so ur basically adding the file to the reply message.
The link i gave has a better description, it has the entire process of sending file to server and downloading file from server codes.

Help required in File Adapter Module Development

Hi All,
I am working out a File to File scenario where my source file is in some different format. Please find the below sample:
<Root>
<ID>100</ID>
<NAME>SAP</NAME>
<END-Root>
Before taking this into IS, I need to change the file to a proper XML format. I need to replace "END-" with "/".
<?xml version="1.0" encoding="UTF-8" >
<Root>
<ID>100</ID>
<NAME>SAP</NAME>
</Root>
I think I can achive this by developing Adapter Modules. I am new to Adapter Module development.
Can you please tell me if there are any inbuilt Adapter Modules for this. If not please suggest me some relevant blogs to solve this issue. Thanks in Advance.

Hi Phani Kumar
There are more than one ways to do this. As per your timelines and skill set you can decide
1. You can use the XMLAnonymizerBean this is an inbuilt module
Check Stefen's blog
Remove namespace prefix or change XML encoding with the XMLAnonymizerBean
2. You can read this complete file in a single field and then you can create XSLT or Java mapping to parse it in a target XML you desire.
Check these

How to process a SOAP Attachment in XI

Hi,
I have a SOAP-RFC-SOAP Synchronous scenario. Here the SOAP Message comes with an attachment. I need to process the SOAP Attachment through XI and need to map the content to the RFC and send the response back to the webservice. Here PayloadSwapBean does not work in Sender soap Adapter. Is there any other option of achieving this.
Thanks,

Exception when trying to create a soap attachment javax.activation. Unsuppo

I am trying to pass an object String [] as a soap attachment.
Reading the docs, if I pass a parameter as type datahandler, it is automatically treated as an Attachment.
I used the constructor DataHandler (Object obj, String mimeType)
where the object was my StringArray, and MIME is the XML representation of
a java type, which according to weblogic docs is NMTOKENS,IDREF or ENTITIES.
It threw the same error for the other two.
Am I using DataHandler correctly, is MIME the SOAP representation of the Java Object in memory.
Thanks for any help

Module Development for XI3.0 Adapters

Hello,
we are currently trying to develop a xi 3.0 adapter module. Modules are a way to expand the functionalities of a xi adapter, in our cas the file adapter.
Our module should be used to perform a more complex transformation from flat file to xml.
We know, that we have to develop the modul as a stateless session bean, and that we have to implement some modul-interfaces.
What we are missing are some examples, code fragments and some more detailed informations.
Anybody out there, who can help us?
Thanks in advance,
Frank Winkler

The easiest way to deploy the module is through Netweaver Developer Studio. Alternatively you can go through SDM.
Hope that's a starting point.

Sender SOAP Adapter Modules!

Hi Can anyone guide me how to write a Sender SOAP adapter module ?

Hi Pooja, thanks for the reply I have seen that.
Please look at the below forum.
SOAP Adapter and plain HTTP
It says "When you write a module for sender SOAP adapter, you have to deal with the incoming message, as the SOAP adapter first calls the customer module, then creates the XI message."

How to download a SOAP attachment using pl/sql

Gurus,
I have a custom pl sql application that is web services based. The custom pl sql application invokes the external web services and updates Oracle Field Service application.
One of the new requirements is to get the signatures from SOAP Attachments (a binary file) and attach it to Field Services transactions in Oracle.
Does anyone has an example of how to download the SOAP attachment file from web service using pl/sql.
The pl sql program uses UTL_HTTP to access web services.
Much Thanx.

I think you may be in the wrong forum, but anyways...
What I think your looking for is the htp.print('insert html here'); function. It's plsql, and writes out html to the web server that calls it.
if you search for htp.print you should find loads of examples.
hope this helps.
Merv.

SOAP Attachment & performances for WLI

Dear all,
I am implementing webservices, accepting a SOAP attachment as parameter. The implementation is based on Workshop / WLI jws file. The web service is RPC style since WorkShop is unable to generate a correct WSDL file with SOAP atttachment & document style (known limitation from BEA).
My problem is concerning attachments. Indeed, in my mind, attaachement are there in order to prevent extra load into the XML parser and to speedup processing and avoid heavy use of memory.
So I made some tests with a simple soap request and attachments. Here are the results (I calculate the time to send and receive response from web service), the web service itself just prints the content type, anything else.
Attachement size | Time
39 kb 344ms
78 kb 406ms
155 kb 484ms
300 kb 750ms
463 kb 1000ms
1389 kb 4600ms
2700 kb 23609ms
5500 kb 140000ms
Of course, the client and server are running on the same machine and are using the loopback interface. So there is no network bootleneck to take into account.
As conclusion, we can see that for small messages, (<300kb) the curve is good... But performances start to fall drastically with messages larger than 300kb. This is not a problem of memory but CPU usage (fully used diring the 1400 seconds).
Any idea, any opened cases ?
Thansk for all,
Pascal Bourgeois
