SAX Parsing in Adapter Module
Hi All,
I need to build a custom Adapter Module where i want to use SAX Parsing for parsing XML document. I tried with a piece of Code but i'm getting following error while running the same:
Error occurred while sending message (GUID 6da4ff1c-3736-4990-1881-a8f09edd5fde): null
When i check the Audit Log the i just see following two lines:
Success Channel JDBC_s_Article_Grp1: Query executed successfully and confirmation skipped. Data may be sent again ("TEST" mode)
Send query result. Size: 1398556 characters
There are no logs being created for module at all. Also when i run the same code with DOM parsing, it works perfectly fine.
I have tries with re-deployment multiple times but no result.
Any pointers?
Regards,
Anurag
try to handle exceptions and use logging to know what the issue is.
That is the best way to troubleshoot your code

JDBC receiver adapter - Error processing request in sax parser
Hello,
I want to INSERT idoc data via JDBC adapter into a MS SQL database. After digging through SAP Help, numerous blogs and forum discussions on SDN and even posting an OSS message I still get the same error:
'Error: TransformException error in xml processor class: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)'
When testing my mapping in the Integration Repository the resulting XML message is:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Employee xmlns:ns0="http://prodrive.nl/xi/HRMasterdata/HRMD_A_2_d_bcommerp">
<STATEMENT>
<T_PD_Employees action="INSERT">
<access>
<KeyTag>00088888</KeyTag>
<PerNo>00088888</PerNo>
</access>
</T_PD_Employees>
</STATEMENT>
</ns0:Employee>
The connection to the database is fine, Sender adapter with a SELECT * works perfect.
Can anyone help me solve this problem? I'm lost.
Best regards,
Roelof Jan BouwknegtHi Bhavesh,
I have tried out the change you suggested. Without success. Message I get back is
- 2006-12-28 10:34:08 CET: Error: TransformException error in xml processor class: Error processing request in sax parser: No 'action' attribute found in XML document (attribute "action" missing or wrong XML structure)
structure in testtool:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Employee xmlns:ns0="http://prodrive.nl/xi/HRMasterdata/HRMD_A_2_d_bcommerp">
<STATEMENT>
<T_PD_Employees action="INSERT">
<ACCESS>
<KEYTAG>00088888</KEYTAG>
<PERNO>00088888</PERNO>
</ACCESS>
</T_PD_Employees>
</STATEMENT>
</ns0:Employee>
Somehow the SAX parser doesn't like the result of my mapping. Maybe there is something wrong with the structure cardinality. Let me describe what I have built:
XSD:
WA_T_PD_Employees - Complex Type
> STATEMENT - Element - Occurence = 1
>> T_PD_Employees - Element - Occurence = 1
>>> STATEMENT - Attribute - Occurence = optional
>>> access - Element - Occurence = 1..Unbounded
Best regards Roelof Jan and thanks for your quick response -
SAX Parser Error in JDBC Adapter
I am using a JDBC adapter to execute SQL statements during mapping runtime. However, it issues me an error regarding the SAX Parser when I have a '&' character in the SQL statement. I am not able to remove the & since it is in the database that I access and it will result to data inconsistency. I think that when the JDBC adapter of XI converts the SQL string to the XML format, it does not include the amp; string to the &, thus causing the SAX Parser to throw the error.
Is there someway I can configure the JDBC adapter in such a way that it will replace the & with &. Or is there a way to display how the JDBC adapter converts the SQL statement to its the XML representation of it?
Thanks a lot.Hi,
For this kind of situation use some unique character combination like "#@!" for replacing "&" then parse the document and the restore the "&" later .
For this convert the input stream into Strring and then replace the occurences of "&".

Adapter Module: Validate an XML with an XSD
Hello all,
I'm developing a PI adapter module (Exchange Infrastructure 3.0) for the Mail Adapter. In this module I need to get each XML attachment and then validate with an XSD schema, for this I'm using the SAX parser.
I successfully retrieved all XML attachments but when I'm trying to use the method setProperty of the SAXParser instance I'm getting an exception, bellow the code snippet.
private static final String SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
private static final String SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";
private static final String XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";
public boolean isValid(byte[] src, AuditMessageKey amk1){
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = null;
spf.setNamespaceAware(true);
spf.setValidating(true);
String[] schemas = new String[MAX_SCHEMAS];
schemas[0] = getClass().getResource(SCHEMA1).getFile();
schemas[1] = getClass().getResource(SCHEMA2).getFile();
schemas[2] = getClass().getResource(SCHEMA3).getFile();
try {
sp = spf.newSAXParser();
catch (Exception e){
Audit.addAuditLogEntry(amk1, AuditLogStatus.ERROR, "MultipleAttachments: Error creating parser.");
return false;
// HERE IS THE STEP THROWING THE EXCEPTION
try {
sp.setProperty(SCHEMA_LANGUAGE, XML_SCHEMA);
catch (Exception e){
Audit.addAuditLogEntry(amk1, AuditLogStatus.ERROR, "MultipleAttachments: Error setting schema.");
return false;
Did Anyone have faced this issue? How can I solve this?
Best regards,
DavidHi David,
we developed a xsd validation with java mapping.
SAP has it's own parser. At the time we developed there was a bad bug in this parser. The parser throwed a fatal error although the xml was valid!
SAP corrected the error. But this is over 1,5 years ago. I recommend a OSS .

How to access Payload in XI Adapter Module
Hello,
I have to enhance a adapter module in xi very urgently. Target is to access a node of the XML payload and retrieve the corresponding value.
This is how my document looks like:
<mt_test>
<element1>
< > </ >
</element1>
<element2>
<LOG_NO>4711 </LOG_NO>
<element2>
</mt_test>
I need now access the element <LOG_NO>. This can only appear one time in the whole xml document. My code that I did so far (inside the process method) to retrieve this element is like this:
XMLPayload xmlpayload = msg.getDocument();
DocumentBuilderFactory factory = null;
factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse ((InputStream)xmlpayload.getInputStream());
Element rootNode = document.getDocumentElement();
< and now I have no clue anymore :-/ >
May you give me an example how to access the node <LOG_NO> and save the corresponding value in a String variable?
I would be really thankful.
Greetings and thanks in advance,
TobiasHi,
>>>found no solution with PI Standard Import to support FTP inside the Adapter Module
why would you? file adapter supports FTP - so you don't need it
>>>In order to use FTP library, is there any standard library available or supported by SUN.
you can use any java ftp client available on google

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
https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/3823 [original link is broken] [original link is broken] [original link is broken](XSLT mapping)
Java Mapping (Part I) (Java Mapping)

This error occurs when the receiver side structure is incorrect.
Your structure seems to be correct.
Please use lower case for action, access and table.
Please check whether the field names are exactly the same as in the actual Database table sadmt1.SPE106TST.
Check if the table has permissions to write.
You can try an alternate structure without using table tag.

Java Mapping Or Adapter Module for MultiLevel File Content Conversion ??
Hi Experts,
Hi All,
As we all know file content conversion cannot parse more than three level even if we use FCC paramenters or MessageTransform Bean /StrictXmlToPlain Bean.
Currently i am facing an scenario where i can expect an content coversion with four or five levels.
for ex.
Target Message Looks like
Header(0..1)
|_____X
|_____Y
|_____Detail(0.n)
|____A
|____B
|____SubDetail(0.n)
|_____Trailer(0.n)
|______rec1
|______rec2
|______rec3(0..n)
|______Subrec1
|______Subrec2
So my question how can i do the FixedLength/CSV in the target system ???
Shall i do java mapping ? if yes then any code example relevant to this type of scenario
Shall i do adapter module development ?if yes then any code example relevant to this type of scenario
Thanks In Advance
Ronit MishraTarget Message Looks like

JMS Adapter module content conversion
Hi,
I'm developing a module for the jms adapter(sender). My requirement is to parse the XI message(text) using some XML parsing api and do some formatting, logic etc and to make the jms adapter create a xml file with the processed information. Jms File Content Conversion does not suit our requirement and thats the reason we are trying this option.
My understanding is: Access the payload in the "process" method of the local ejb, apply XML parsing using JDOM etc, make a xml which should be the output of the jms adapter. This xml will be the xml with my user defined tag elements after content conversion. Can i form this xml and assign to the inputModuleData? Will the jms adapter use this string to create the xml and send to IS? Are there any other parameters to be set or processes to be done?
Also in which sequence should I put my adapter module in communication channel.
================================================
My code snippet:
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData)
throws ModuleException
Object obj = null; // Handler to get Principle data
Message msg = null; // Handler to get Message object
try
obj = inputModuleData.getPrincipalData();
msg = (Message)obj;

String messageStr = xmlpayload.getText();
String inputStr = null;
String tags[] = new String[2];
String values[] = new String[2];
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS,"sample: Inside sample Module---before content conversion");
String tagvalue1 = messageStr.substring(messageStr.indexOf("BEGIN+"), messageStr.indexOf("'");
String tagvalue2 = messageStr.substring(messageStr.indexOf("'"), messageStr.lastindexOf("ENDING");
tags[0] = "tag1";
tags[1] = "tag2";
values[0] = tagvalue1 ;
values[1] = tagvalue2 ;

throw me;
return inputModuleData;This is for sender channel. The doubt in adapter module is in the process block how will I get the main data being read by the jms adapter from the text file.As I am reading text file from websphere MQ, the content of the text file can be obtained thru xmlpayload.getText() or is there any other way.
obj = inputModuleData.getPrincipalData();
msg = (Message)obj;
XMLPayload xmlpayload = msg.getDocument();
String messageStr = xmlpayload.getText();
At present I am using my adapter module before call sap adapter, but before sap adapter there are two other modules(toBinary and to Xmb), so shld I place it before both or after both the modules.
Thanx in advance

Problem changing XML element in Adapter Module
Hey!
I am developing an adapter module to transform a coded password back to clear text. I have access to the XML element where the password is and I get to transform it, but I have 2 problems as also stated in the code:
1) I cannot set the new value back to the node. I try with
firstNode.getFirstChild().setNodeValue(decodedPwd);
but this does not seem to work. How can I achieve this?
2) Between the first issue and the code
msg.setDocument(xmlpayload);
I am not sure how to get my new values for the node back in the XMLPayload. How can I achieve this?
Here is the code:
msg = (Message) inputModuleData.getPrincipalData();
XMLPayload xmlpayload = msg.getDocument();
factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse((InputStream)xmlpayload.getInputStream());
password = (Element)document.getElementsByTagName("ns1:passord").item(0);
firstNode = password.getFirstChild();
pwd = firstNode.getNodeValue();
if(pwd != null){
decodedPwd = Decoder.decodeString(pwd);
// THIS FAILS!
firstNode.getFirstChild().setNodeValue(decodedPwd);
//HOW TO SET NEW NODE VALUE TO XMLPAYLOAD HERE?
msg.setDocument(xmlpayload);
inputModuleData.setPrincipalData(msg);
return inputModuleData;
Help is much appreciated!
Thanks!
regards OleHey!
The problem was solved. The code snipped I found was:
DOMSource DOMSource = new DOMSource(document);
ByteArrayOutputStream myBytes = new ByteArrayOutputStream();
Result dest = new StreamResult(myBytes);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.transform(DOMSource, dest);
byte[] docContent = myBytes.toByteArray();
xmlpayload.setContent(docContent);
msg.getDocument().setContent(xmlpayload.getContent());

Hi Experts,
I have written an Adapter module to set the target file name (because it could not be done with usual DynamicConfig in mapping because of multimapping). I am facing a peculiar issue with it. For ex: I have 3 msgs. First msg started executing the module to set the target fillename and about to end the module execution. Meanwhile second msg enters the module execution and changes the file name. This is resulting in first msg to post a file with name set by second msg. I have put "Maintain order at runtime" in interface determination of ID to fix the issue. But this isssue is still persisting. Please let me know, how can a msg acquire a lock on the module and untill it finishes it execution, no other msg should start the module execution.
Thanks,
RakeshHi Michal,
I have written below code to name the \target file in module code. I have also set "Adapter specific msg attributes" in receiver file adapter and referred file name from dynamic config:
public ModuleData process(ModuleContext inputModuleContext, ModuleData inputModuleData)
throws ModuleException {
Object obj = null;
Message msg = null;
AuditAccess audit = null;
MessageKey keyOut = null;
obj = inputModuleData.getPrincipalData();
msg = (Message) obj;
keyOut = new MessageKey(msg.getMessageId(),msg.getMessageDirection());
try
audit = PublicAPIAccessFactory.getPublicAPIAccess().getAuditAccess();
audit.addAuditLogEntry(keyOut, AuditLogStatus.SUCCESS, "Module Started Execution..");
MessagePropertyKey mpk = new MessagePropertyKey("FileName","http://sap.com/xi/XI/System/File");
InputStream is = msg.getDocument().getInputStream();
DocumentBuilderFactory docBuilderFact = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFact.newDocumentBuilder();
Document doc = docBuilder.parse(is);
Node nl = (Node) doc.getDocumentElement();
Node n = nl.getFirstChild();
Attr a = (Attr) n.getAttributes().item(0);
String Num = a.getValue();
audit.addAuditLogEntry(keyOut, AuditLogStatus.SUCCESS, "Number is "+Num);
Attr a1,a2;
if (n.getNodeName().equalsIgnoreCase("Create"))
a1 = (Attr) n.getAttributes().item(1);
String sd = a1.getValue();
audit.addAuditLogEntry(keyOut, AuditLogStatus.SUCCESS, "Start Date is "+sd);
String fileName = sd + "-" + Num + ".xml";
msg.setMessageProperty(mpk,fileName);
else(n.getNodeName().equalsIgnoreCase("Update"))
a2 = (Attr) n.getAttributes().item(2);
String sd = a2.getValue();
audit.addAuditLogEntry(keyOut, AuditLogStatus.SUCCESS, "Start Date is "+sd);
String fileName = sd + "-" + Num + ".xml" ;
msg.setMessageProperty(mpk,fileName);
catch(Exception e)
audit.addAuditLogEntry(keyOut, AuditLogStatus.ERROR, "Execption Occured.." + e);
return inputModuleData;
When 3 msgs get created for Create interface, File name set by first msg is being changed by second and file for first msg is posted with name set by second (because second msg has changed the target file in module code by that time ) -
Testing Adapter Module in NWDS
hi,
I have got a code for adapter module,I wanted to test it standalone using NWDS.
class XML2EdifactBean
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData)
throws ModuleException { //Some Code... }
I am getting some error while executing the adapter module ,so I want to call the function using main method.Can you provide me with a sample code for this.
regards,
Ujjwal Kumar.This would be too complex to do all necessary steps for a stand alone test.
I recommend to split the generic adapter module stuff and the part, you really want to do something.
For the adapter modul, which we used on Teched session:
GetHostName.java code for 3.0/7.0
I did following: I introduced a helper class and passed the DOM code
public class HelperClass {
String hostElementName = "host";
String hostName = "host";
public static void main(String[] args) {
try {
InputStream in = new FileInputStream(new File("in.xml"));
OutputStream out = new FileOutputStream(new File("out.xml"));
new HelperClass().execute(in, out);
} catch (Exception e) {
e.printStackTrace();
public void setHostElementName(String hostElementName){
this.hostElementName = hostElementName;
public void setHostName(String hostName){
this.hostName = hostName;
public void execute(InputStream in, OutputStream out){
try {
DocumentBuilderFactory factory;
factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(in);
Element rootNode = document.getDocumentElement();
if(rootNode != null) {
Element childElement =
document.createElement(hostElementName);
childElement.appendChild(document.createTextNode(hostName));
rootNode.appendChild(childElement);
// Transforming the DOM object to Stream object.
TransformerFactory tfactory = TransformerFactory.newInstance();
Transformer transformer = tfactory.newTransformer();
Source src = new DOMSource(document);
Result dest = new StreamResult(out);
transformer.transform(src,dest);
} catch(Exception e){}
in the bean class, I used the helper class:
XMLPayload xmlpayload = msg.getDocument();
InputStream in = xmlpayload.getInputStream();
ByteArrayOutputStream out = new ByteArrayOutputStream();
HelperClass hc = new HelperClass();
hc.setHostElementName(hostElementName);
hc.setHostName(hostName);
hc.execute(in,out);
byte[] docContent = out.toByteArray();
if(docContent != null) {
xmlpayload.setContent(docContent);
inputModuleData.setPrincipalData(msg);
Now I can test the parser in the NWDI

msg = (Message) obj;
XMLPayload xpld = msg.getDocument();
String xmltxt = xpld.getText();
InputStream in = new ByteArrayInputStream(xmltxt.getBytes("UTF-8"));
& then using DOM parser i am trying to read the contents.
But i am not able to read anything. And no exception is raised.
How can i read contents of this xml file.
Thanks,
Mayankhi,
I am still getting same Blank payload.
My Code for Parsing is:
doc = db.parse((InputStream) xpld.getInputStream());
NodeList list_Set=doc.getElementsByTagName("record");
NodeList list_Set1=doc.getElementsByTagName("EmployeeName");
NodeList list_Set2=doc.getElementsByTagName("EmployeeID");
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "12");
String input = "";
for(int i = 0; i < list_Set.getLength(); i++){
Node f=list_Set1.item(i);
f=f.getFirstChild();
String str_f=f.getNodeValue();
Node f2=list_Set2.item(i);
f2=f2.getFirstChild();
String str_f2=f2.getNodeValue();
input = input + str_f + "," + str_f2 + "END" ;
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "Value added from incoming payload");
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, input);
And in RWB monitoring, i am able to see:
2009-10-01 14:20:51 Information 12
2009-10-01 14:20:51 Information UNDEFINED
2009-10-01 14:20:51 Information 14
So UNDEFINED is coming for input.

SAX-parser and mapping on the XI
Helllo everybody,
I'm trying to map an xml-document using the SAX-parser.
I'm reading the data using an impustream. the problem is, while testing on the XI, the following message comes :

This seems that u r trying parse a file rather than valid XML document..
Usually you will notice this problem when u r trying to parse a payload which is in txt format usually when u r using File Adapter message protocol as "FILE" instead of "FCC".
Usually SAX is an API Desinged to parse Valid XML Documents only.
If you want to do manipulations on NON XML data better to use Java.io.InputStream & OutputStream.
