Java Mapping (Validation)
Hi Guys
Validations using Java for those not having PI7.1
I followed this blog for validation of XML.
I have coded the JAVA Program in NWDS as per the blog, all fine but am not sure about the schema step.
What i did was:
1) Exported the .xsd of the Message type.
2) Then Schema.xml file creation i am not sure of it
Do any one know how to do that , and what is the purpouse of the Schema method in the Java Mapping.
Is this blog does a input initerface format check and write in to a log.
But cannot we do this with the help of Alert by triggering mails ??
Can we achieve element level vaslidation (to all element of the XML) using this method.
Kindly share u r views
Srini
Hi Santosh,
Thx for u r reply.
I understood what u r saying .
One more question :
See u r Doc is validating particular element , date and time using api.All good, what if i need to validate entire XML Elements , should i repeat the same for entire element.
i was so curious with his blog because , it was generic and moreover i thought i can validate entire XML , by not sticking to particular element.
What is IA ?? U Memtioned ??
Could above requirment can be achieverd r else i should get each element and validate , no other go
based upon on the outbound interface
regards
srini

Xerces for XSD 1.1 Validation not working in Java Mapping
Hi Experts,
We are trying to use XSD 1.1 (assertion feature) validation for the XML payload in a Java mapping program. But I am getting the following exception:
java.lang.IllegalArgumentException: http://www.w3.org/XML/XMLSchema/v1.1 at javax.xml.validation.SchemaFactory.newInstance(SchemaFactory.java:186)
This is happing for the statement:
SchemaFactory factory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");
The reason (apparently) is because it is not able to instantiate the class org.apache.xerces.jaxp.validation.XMLSchema11Factory , which is the Xerces implementation of the SchemaFactory class.
I have tried following things so far -
1. If I try to validate an xml against an xsd 1.1 schema in a standalone program, it works perfectly fine.
2. If I try to deploy this whole functionality on to the server through an EAR (like an adapter module), there again it works.
3. Also tried this before instantiating the SchemaFactory -
System.setProperty("javax.xml.validation.SchemaFactory:http://www.w3.org/XML/XMLSchema/v1.1","org.apache.xerces.jaxp.validation.XMLSchema11Factory");
4. I tried by creating the Imported Archive objects for all the Xerces jars that we require for validation, within the same SWCV, namespace. But still I get the same exception as above (IllegalArgumentException)
5. The link [http://help.sap.com/saphelp_nw70/helpdata/en/b6/8097f5a5edea4f8dfc87ac87082b22/content.htm ] mentions that we need to place all the necessary jars at location <SAP_J2EE_Engine_install_dir>/cluster/server/bin/ext /. But even after placing the jars there, I get the same exception.
I am not sure how we need to handle this. Has anybody faced a similar situation? Any suggestions?
Regards,
SudheerHi Stefan,
Thanks for the reply.
We are on PI 7.1 SP 06. The standard XML tools from jdk supports only XSD 1.0, as far as I know. And XSD 1.0 does not have the Assert feature (also known as, co-occurrence constraint). More details are provided here - [http://www.ibm.com/developerworks/library/x-xml11pt2/]
To use XSD 1.1, we need a different implementation like Xerces-J. I am not sure how we can use it without external jars. I would like to mention again that I could achieve this by using an adapter module (EAR containing the jars), but I need to do this in Java Mapping (imported archive).
Do you know how we can achieve this in any other way? Any other suggestions welcome.
Thanks & Regards,

XML Validation with XSD in java mapping
Hi experts,
I have created an interface to send differents messages between bussines system, the bussiness system receiver is put in the message, to get this value I have a configuration file indicating the path of this field for each message type. In a java mapping I transform the message sent in this structure:
<document>
<message>HERE THE MESSAGE AS STRING</message>
<parameters>
<sender>HERE SENDER BUSSINESS SYSTEM</sender>
<receiver>HERE RECEIVER BUSSINESS SYSTEM</receiver>
</parameters>
</document>
the messaging interface works fine, but now I have to validate the XML vs XSD. I need doing in a java mapping because the messaging interface send the message and a email to sender in error case.
To do this validation I have implemented two java mappings that works fine in my local, the first way is with class Validator of java 5, but my system PI 7.1 return an error with this class. The second way is with SAX parse:
String schema = "XXXXXxsd";
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
docBuilderFactory.setNamespaceAware(true);
docBuilderFactory.setValidating(true);
docBuilderFactory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage","http://www.w3.org/2001/XMLSchema");
InputStream is = this.getClass().getClassLoader().getResourceAsStream(schema);
docBuilderFactory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource",is);
in my local works fine but in PI always return OK never fail.
For this moment the schema is hardcoded to do proofs, in the future will be loaded from my configuration file.
Any idea?
Thanks in advance
Josehi Jose,
PI 7.1 has a built in feature available called XML vaidations ..
your source xml can be validated against a XSD placed at a specific location on the PI server..
validation can be performed at adapter/integration engine

Java mapping for XSD Validation
Hello,
I have developed a Java mapping to validate an XML based on XSD.
I works fine and generates a message with error details.
I would like to create a report with all errors encountered during this Validation and to stop this message from being sent to the partner.
But this Java mapping stops at first error encountered and generates an error message with first error only even though document has more errors further.
Can anyone please let me know if there is an option to log all errors without allowing the message to go through?
Thanks.
Best Regards,
ShwetaYes, as abhishek mentioned when you validate the instance document (XML) using standard parsers then they validate based on the spec provided in XSD and they stop at the first error. The link given using dom parser via java code will also stop at the first error.
If you really want to validate the entire instance document then you might have to create a custom validator class which does validation for each and every fields and store it in an object like Vector or List or Map object. Then when you throw exception you can retrieve that Map object in the catch block and read all the individual error messages and display in log. This requires additional effort. In this case you dont rely on parser validation. Completely custom based.
Example:
Vector errorList = new Vector();
if the field name is SSN and if you see any alpha characters you add error for that field in the errorList
If(SSN.matches("[a-zA-Z]")){
do nothing
}else{
errorList.add("The fieldName SSN contains other than alpha characters");
Like that you have to add error string mesg in the errorList object and return the errorList at the end. -
Special Characters in a Java Mapping
Hello everybody,
in our XI we have an Interface Mapping that uses a Java Mapping, this Mapping is doing a XSD-Validation of a XML-File.
In one XML-File there is more than one special Character (ó, O², ü..). The XI-Parser hat no problems with these characters except one, eventhough this character (ó) exists more than once in the document, the parser doesn't recognize it in only one position (While Parsing the "ó" turns to a "��").
I tested the Mapping in Eclipse and it works correctly. The question is, why the special character could not be interpreted in only one position in the document.
I guess it is a bug in the XI-Parser.
I will be thankful for your help.
Best regards
AdnaneThis ó has the same Hex-code as all the others and it is in the same environment.
I definned in the source XML in the repository test the code Page in the XML-header as follows :
<?xml version="1.0" encoding="UTF-8"?> and that works. But when I test the Process at the runtime the problem above occurs.
I think that the interface Mapping is getting a source XML without a header, which defines the encoding as UTF-8, because when i test the Mapping in the repository with the XML-file without the Header information, the problem with the ó occurs.
My question is, where can i define the Encoding of the source-XML of this Interface Mapping?

Should we avoid Graphical mapping and stick with Java mapping?
After developing mappings in XI for a month, I just don't see any good reasons to use Graphical mappings over Java mappings. Maybe some experienced users here can give me some valid reasons why we should choose Graphical mappings. Here is what I think:
Disadvantages of Graphical mappings:
1. No way to perform automated unit testings. This is probably the biggest reason I hate it. You can do some tests manually when you work in Integration Builder. But there is no way you can write some unit testing utilities to automate the task.
2. Complexity. Even for some simple requirements, your Graphical mappings can become complicated and hard to understand. A lot of times, I find myself staring at several dozens of graphical nodes and try to understand what it does.
3. Impossible to reuse. This is totally against the DRY (Don't repeat yourself) principle. For example, to generate messages for JDBC adapter, it is common to have two identical fields for primary keys: one in the access node and another in the key node. If you change the mapping logic in one, you have to remember to change the other.
Advantage with Java mappings:
1. Fully automated unit testing. You can create JUnit tests along with your Java mapping classes and use Maven or other build tools to perform automated unit testing.
2. Your choice of XML parsing and binding. With Java mapping, you can choose any open source framework for XML parsing and binding. For example, with XMLBeans, I can convert XML input message to a Java object, transform to another Java object and write to output message. And each Java object is generated from its corresponding XML schema.
3. Highly reusable. We can use fundamental object-oriented designs to create highly reusable mapping components.
4. Better version control. Since the mappings are just Java classes, we can use CVS or SVN to track code changes.
5. Better build tools. We can fully utilize build tools like Ant and Maven to automate the build, unit tests, or even generate documents and mapping web sites.
So do you guys agree? Maybe I am still new to XI or I am missing some important things. But at this point, I just don't see why I should use Graphical mappings. Is there anyone developing XI interfaces completely with Java mappings?
Thanks in advance for any comments!

Could you explain more why the graphical mapping has better performance? I thought the graphical mapping is compiled into a Java class in the runtime anyway.

I mainly think about inheritance. If I have to build 10 interfaces and they all have some common behavior, I can create a base interface class to encapsulate the common logic. But with graphical mapping, you have to duplicate them in each interface.
> Disadvantages of Java mapping:
> 1. Performance
Same as above. I just don't see why Java has worse performance. I actually think Java should have better performance. You can optimize the code anyway you want. In some cases, you have to use queue functions in graphical mapping but it's not necessary in Java.
> 2. All might not be well versed with Java Code(though

I am not asking everyone to abandon graphical mapping. I am just wondering which one is better when you have skills for both.

You can create functions in Java too. All you have to do is to remember the function name.

Getting Error in java mapping: Parsing empty source. Root element expected!
Hi Experts,
I am using java mapping for schema validation of input message. I have followed all the standard procedures and implemented the java class in the interface mapping.
My interface mapping is like this:
OrderData --->Java Class ---SchemaValidate
Mesg Map ---OrderData_to_BAP --->BAPI Msg
So first I want to validate the schema of the input message. If the input message is invalid then XI should throw an exception. Then I use the actual message mapping to map the input order data to the BAPI input parameters.
In the java code I am using xerces parser.
The java code works fine when I run it as a standalone application.
The interface mapping also works fine if I don't include the java mapping. Ofcourse schema validation does not happen.
But when I test the interface mapping by including the java mapping then I am getting the error:
Call method execute of the application Java mapping SchemaValidate
Java mapping SchemaValidate completed. (execute() of SchemaValidate
com.sap.aii.utilxi.misc.api.BaseRuntimeException: Parsing an empty source. Root element expected!
What am I doing wrong? Why it is not getting the root element?
My Java code is as follows:

Edited by: gopalkrishna baliga on Feb 28, 2008 9:34 AMHi Stefan,
I did the code changes to return output stream and the java code works perfectly in standalone mode in my PC.
But when I use the same in the Java mapping with XI then It throws an error "Getting Error in java mapping: Parsing empty source. Root element expected!".
My XI J2EE server has JDK1.4.3.11.
Is there any limitation of using SAX parser in XI? If Yes, then which parser should be used for schema validation in XI?
I have included the XSD file for schema validation along with class files in the .jar file. This jar file is then imported in XI repository. Is the XI engine not able to read the XSD file?
Do I have to handle reading XSD file differently? Any suggession how?
Is this parser error due to some security access?
Kindly help me! I have been struggling with this problem since 2 weeks. I will be greatfull to you if you can help me.
Thanks

Hi,
I'm using SAX Java mapping in one scenario. Problem is when I get some Croatina characters, like Đ or u0160,
output XML is not valid. XML Spy complains, IE complains and so on. Customer is sure that data ( XML in CLOB field in Oracle DB) is UTF-8? What could be a problem?
What I'm doing is reading entire XML into string with help of BufferedReader, then do some manipulation and write String into byte array with:
byte[] bytes = file.toString().getBytes("UTF-8");
saxParser.parse(new ByteArrayInputStream(bytes), handler);
and then of course parse XML. readLine method reads data and problematic is "�" - 0 - 0xC490.
For this character XML Spy doesn't complain, IE also. After conversion, this character looks like "Ä?" - 0xC43F, and this is not good any more. Why?Hi Stefan,
I've finally done it. Code as foollws:
public void execute(InputStream in, OutputStream out)
throws com.sap.aii.mapping.api.StreamTransformationException {
DefaultHandler handler = this;
SAXParserFactory factory = SAXParserFactory.newInstance();
try {
SAXParser saxParser = factory.newSAXParser();
fStreamOut = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
encoding = "UTF-8";
if (map != null) {
mappingTrace = (MappingTrace) map
.get(StreamTransformationConstants.MAPPING_TRACE);
InputStreamReader is = new InputStreamReader(in, "UTF8");
BufferedReader reader = new BufferedReader(is);
StringBuffer file = new StringBuffer();
String line = new String();
try {
while ((line = reader.readLine()) != null) {
file.append(line);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
Date d4 = new Date();
file = replaceREGEX(
"<\\?xml version=\"1\\.0\" encoding=\"UTF-8\"\\?>", "",
file);
char[] cArray = file.toString().toCharArray();
Date filedat = new Date();;
SimpleDateFormat df = new SimpleDateFormat("yyyyMMdd_HHmmss_SSS");
String fName = df.format(filedat) + "_El_Invoice.xml";
Writer out1 = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream(fName), "UTF8"));
try {
out1.write(file.toString().toCharArray());
out1.close();

File outFile = new File(fName);
outFile.delete();
} catch (Throwable t) {
if (mappingTrace != null) {
mappingTrace.addInfo(t.toString());

problem was also in method for writing in output stream, so I've changed it:
private void printOutPut(String sOP) {
try {
// fStreamOut.write(sOP.getBytes());
fStreamOut.write(sOP);
} catch (IOException e) {
e.notify(); -
XML not well formed - Java Mapping, Webservice to RFC Scenario
Hello All Experts,
I have facing a strange type of error. I have written a Java Mapping which implements a DOM parser to take a request from a Webservice and validate it on the basis of some prerequisites. i.e. If data in the incoming request is valid, it creates a message of the same structure type as the input. If the incoming data is incorrect or incomplete; It generates an Error response structure.
When I run and test the same mapping program using Editplus Java editor for the error scenario; it executes perfectly and creates the correct error XML structure. (I checked it by importing the structure in the XI Message mapping test tab). But when I create jar of my java mapping program and test it in my interface mapping, it gives me "XML not well formed error" (Problem while building the tree).
Any idea as to why is it behaving in such a way? There are 2 reasons which come to my mind as of now:
1. The initilization of my input and output streams in the public static void main:
InputStream in = new FileInputStream(new File("Input.xml"));
OutputStream out = new FileOutputStream(new File("Output.xml"));
validateXML myMapping = new ValidateXML();
myMapping.execute(in, out);
The Output.xml has the xml structure for the correct case, do I have to initialize my outputstream for the error file? say error.xml
2. My Webservice interface is a sychronous interface (Request / Response) and output of the Java mapping program are two asynchronous interface. (I'll use a synch-asynch bridge when this works) - Is that causing a problem?
Please help.
Best regards,
VarunHello Varun,
it gives me "XML not well formed error" (Problem while building the tree).
I have come across the same error message while testing in interface mapping. My problem was when an exception occured in java mapping, the execution terminates with the messages XML not well formed error". In order to solve this issue what i did was catch the exception type TransformerException and in that catch block throw StreamTransformationException exception in main methos of mapping program i.e execute().
eg:-
catch (TransformerException e) {
throw new StreamTransformationException("Can not write XML.", e);
By doing this you will see the exception raised , because some times when you execute your mapping with mail() method, though it create the file, when you try to open it will give error if any exceptions occured in mapping. By using the above notation you can handle those in java mapping.
Hope you have gone through this blog.

Read DataType Definition in a Java Mapping,
Hi,
Is there a way to load a DataType Definition and parse the fields and attribute of this data type from java code?
I am in a custom Adapter Module (PI 7.1) and need to dynamically load the definition of a DataType to do some FCC.
I would like to do the FCC based on the DataType definition rather then on the Communication Channel's adapter module configuration.
Thanks,
MartinHi Martin Lavoie,
I understand, you are getting a flat file and want to convert it into XML or the other way, converting XML to flat file in SAP PI 7.1 using File channel.
First, why you are going for Adapter module? (I think even you don't like it) It is resource intensive to develop, running in production system, maintain. If already there is an adapter module, leave it as it is. Consider using Java mapping over adapter module. Java mapping is relatively less resource intensive to develop, running in production system, maintain. Java mapping can do the payload conversion what you are planning to do in adapter module. If you write adapter module (generic), you have to use it in interfaces (all channels) where you need to transform the payload. If you write java mapping (generic), you can use it in operational mapping in all interfaces where you need payload transformation, along with other graphical mappings.
Second, as of now, there is no way to access Data type XSD (which are declared in ESR) using SAP PI. In PI 7.1 EHp1 payload validation using XSD can be done, by placing XSD file in folder on PI server. From PI 7.3, validation is based on Data type (XSD) defined in ESR. First place, you are interested in payload transformation not payload validation. So there is no way you can access XSD in ESR from Adapter module dynamically. I guess you can upload XSD along with adapter module, but maintenance in not all easy.
Finally, I donu2019t recommend adapter module for you requirement. Try using FCC. You may say whenever there is change in XSD (change in field lengths), you have to change FCC (edit the channel), and I donu2019t see better option than this. If you think FCC will not be sufficient for your requirement, and then go for Java mapping. Writing generic java mapping will be a good challenge. Java mapping should be uploaded with XSD (or parameter file) for every interface and should be edited if there is a change in XSD.

One simplest way is read the data element value as the string and ignore first six or seven characters by using substring method or so... Use the return value string for parsing the values from respective tag element using parser or manually

Configuration in Java Mapping.
Hi Folks, Here I am in real Need of Some inputs regarding JAVA Mapping. Actually I am working on the Change of a scenario. I just Added some fields to the interface. I added these fields on the Sender structure and the receiver structure.
I did mapping also for the added fields. Till XI part its working fine. The problem is When I see the Interface mapping they are using the Java Class Mapping as well with the message mapping.
I am very new to JAVA. I dont know even A..B..C..D of JAVA. That is the reason I am waiting for some to help from our Community.
Here are some inputs regarding the JAVA mapping. I did some research and find out that they are using the JAVA Mapping for XML Validation. So I came to know that we dont need to change the JAVA files. Java file just reads the Incoming structure and writes to the receiver. Inside the JAVA mapping it is using the XSD file to capture the incoming structure.
Here is the problem, when I double clik on the java mapping, it is heading to the Imported archives in which we are having .java, .class, .XSD files already imported with some path information. when I just check the code by double clicking the XSD structure it is showing the old XSD. it is not updated with the added fields. So when ever I am testing the Interface its throughing an exception.
Can any body please help me out in this matter.
As i am not going to change the JAVA files, Do I need to install the J2SDK in my local Machine.
What ever the path is showing in the imported archives, will that be in the XI server or again in our local machine. Do we need to create the folders to save any files on our local machines.
I am in need to change the XSD file in the path. where I need to change the XSD.
can any body please gimme the clear process regarding java part which I need to follow to complete my development. even though i completed 80% of my development I am struggling with this config from past 4 days. Please help me out. Looking for the positive responses.
Thanks,
Ramana Avula.Hi do one thing
Export the whole imported archive for e.g let the name be ABC.
When you click on ABC you find .java .class & XSD file.
export the archive with a .jar extension
for e.g ABC.jar
Now open this jar file with winzip.
you will see the three files i.e. .class .java & XSD
Now using winzip just replace the old XSD with new
The name should be same.
Take care if the XSD file is not present inside any folder
if so then replace it inside that directory only and not outside any folder
for e.g. /com/company/ folder have your .java & class file
but /com/company/xsd/abc.xsd is your xsd file
so replace it in appropriate folder only
And then reimport it back in the same archive

Java Mapping to Digital Signature (web service scenarios)
Hi All,
I'm working with Web Service Scenarios and I have a problem.
The Web Service has a Schema for validation data and I send data to method of WS, example:
Web Service Description
<SendData xmlns="http://www.sdn.com/schema.xsd">
<InputXML>string</InputXML>
</SendData>
For send data to "InputXML" is obligatory digital signature in Java.
I created a Java Mapping where get message of schema xsd, clear prefixes of tag and convert all schema to string.
Now Web Service response a error, because string is not contain "<" ">" just contain asc & lt; & gt;
Ex:
& lt;CodigoMunicipio& gt;2927408& lt;/CodigoMunicipio& gt;
In Debug Java Mapping in statement:
before
<CodigoMunicipio>2927408</CodigoMunicipio>;
rootelement.appendChild(element);
After
& lt;CodigoMunicipio& gt;2927408& lt;/CodigoMunicipio& gt;
And If use a rotine to convert it, in sxi_monitor generate a exception because not understand string field.
Can you help me?

BrunoHi Bruno,
there are two ways to nest a xml document into another xml document.
The first one is escaping the XML, just like you did:
<document_one>
<input_xml>
>document_two<>tag_a<value>/tag_a<>/document_two<
</input_xml>
</document_one>
http://stackoverflow.com/questions/1091945/where-can-i-get-a-list-of-the-xml-document-escape-characters
The other is using the CDATA tag.
<document_one>
<input_xml>
<![CDATA[<document_two><tag_a>value</tag_a></document_two>]]>
</input_xml>
</document_one>
http://www.w3schools.com/xml/xml_cdata.asp
Then, if your webservice expects to receive a XML document inside the InputXML tag, probably it will be able to handle one of these techniques.
Best regards,

Handling Java Mapping Exception in BPM Transformation step
Dear SDN members,
I have developed a File to File scenario using BPM as follows.
Step 1:
Sender file adapter picks the file from FTP server and using file content conversion mapped to XML structure.
Step 2:
BPM will recieve the XML payload , immediately in the block a transformation step is called with an interface mapping. In the interface mapping a Java mapping will be executed with certain data validations on the XML payload. If found any invalid data is there a suitable excptions will be raised . Here the transformation step should be catch the error and control should be sent to exception block to place the recived file as a error file.
else if the transformation is executed with out any issues, the file will be placed in success folder.
But in the transformation step, though java mapping thorwing exceptions, the control not going into exception block, instead it is continuing to next step i.e the file is placing in the success folder.
Can anybody tell me, how to handle the exceptions raised in java mapping in the BPM transformation step?
I have refered all the SDN blogs, forums related to this issue, but could not able to find the answer. Please help me?
Thanks & Regards
Vijayanand PoreddyHi Abhishek,
Once the file is picked from FTP server then sent to BPM,
the BPM steps
Step1:
-->Recive
Step 2:
Block Starts
---Block Start: New Transaction
---Block End : New Transaction
---Exception : Error
Step 3
Inside the Block
Transformation Step
--Interface Mapping: <IM Name>
-- Check box ticked for Create New Transcation
-- Exceptions
--System Error: Error
--Source Message: Message recieved in Recieve Step (Step 1)
Step 4:
--Send
--Source Maessage: Output message from the Transformation Step
Block End
Inserted a Exception Branch for Block
Steps inside Exception Branch
-Control
--Throw Alert
--Alert Name
In the above scenario
The transformation step is not throwing error even my interface mapping going to error. The same transformation step if i place outside the block next to recieve step, then the transformation step is throwing error and BPM stops the process.
Also, when transformation is inside the block, i have used the exception handling on the send step inside the block. here it is throwing error as the source message payload is empty. because in the preceding transformation step the interface mapping is failed due to which there the target will not be filled. But even though it is not entered into exception block.
