JAVA Mapping (DOM)
Hi Guys,
Can i test my JAVA Mapping (DOM).
I create all coding as per the requirment . Is it a way that in the NWDS in can give input XML Document and test there in Eclipse before am using it in the XI Mapping.
How to pass "InputStream in" XML document and read the output.
Am bit new to JAVA programing.
If there is anyu way plz do provide me an idea , that help me in debigging well my JAVA Programing

Namespace missing in java mapping DOM ?
Hi,
I am creating java mapping using DOM, but why i cannot create a namespace using this code ?
Document targetDoc = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
Node docRoot = targetDoc.appendChild(targetDoc.createElementNS("urn:sap-com:atp:ABC40:base", "ns1:Vendor_SQL"));
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
// create source and result wrappers and perform transformation
DOMSource source = new DOMSource(targetDoc);
StreamResult result = new StreamResult(outputStream);
transformer.transform(source, result);
expected result in xml :
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Vendor_SQL xmlns:ns0="urn:sap-com:atp:ABC40:base">
</ns0:Vendor_SQL>
result :
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Vendor_SQL>
</ns0:Vendor_SQL>
Please advise whether i was missing any other required step ?
Note : testing using NWDS 7.0 SP 17
Thank You and Best Regards
FernandHi Lesmana,
Can you change the second line in the code like below and give a try::
Node docRoot = targetDoc.appendChild(targetDoc.createElementNS("ns1:urn:sap-com:atp:ABC40:base", "ns1:Vendor_SQL"));

Context change by DOM parsing Java Mapping in XI
Hi Team,
I would like to know that how can I handle Context Change by DOM Parser Java Mapping in XI.?
Suppose the source XML structure I have like below:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Header xmlns:ns0="urn:bp:xi:hr:edm:test:100">
<FileName>
<filesub>
<subname>a</subname>
<subname>b</subname>
<subname>c</subname>
</filesub>
</FileName>
<FileName>
<filesub>
<subname>d</subname>
<subname>e</subname>
<subname>f</subname>
</filesub>
</FileName>
</ns0:Header>
Where the field FileName can occur maximum thrice(0...3) but the subname field is (0....unbounded) but in the target source I would like to have as given below:
<?xml version="1.0" encoding="UTF-8" ?>
- <MT_Test4 xmlns="urn:bp:xi:hr:edm:test:100">
- <Header>
<FileName>a</FileName>
<FileName1>d</FileName1>
</Header>
- <Header>
<FileName>b</FileName>
<FileName1>e</FileName1>
</Header>
Header>
<FileName>c</FileName>
<FileName1>f</FileName1>
</Header>
</MT_Test4>
That means the first value from every context of the source field is forming my first and second value in my target first context.Thensecond value from every context is forming my 1st and 2nd value of my target 2nd context and finally 3rd value of every context is forming my 1st and 2nd value of my target 3rd context.Is this possible to done through DOM parsing or we have to do it by UDF only?Hi Atanu,

one more thing in this line "textChild=docOut.createTextNode(s k + j );" somehow the the third braces one opening before k and one closing after j is missing for unknown reasons. Please correct it when you actually run this code.

Java Mapping Using DOM Parser.
Hi Experts,
I am new to Java mapping and i have followed the link
http://scn.sap.com/thread/3173071 and it is working fine. It is for only one item. I have tried to modify the code and i placed a for loop to go create the Output Node based on the No of Input Nodes and it is giving the error as below. But my requirement is
Input.xml : -
<?xml version="1.0" encoding="UTF-8" ?>
<ns0:DT_Source xmlns:ns0="urn:java_mapping2">
<Person1>
<Name>Alex</Name>
<Surname>Stewart</Surname>
</Person1>
<Person1>
<Name>Sam</Name>
<Surname>Abdreson</Surname>
</Person1>
</ns0:DT_Source>
Output.xml:-
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<ns0:DT_Target xmlns:ns0="urn:java_mapping2">
<Person2>
<EmpName>
<Emp>Alex Stewart</Emp>
</EmpName>
</Person2>
<Person2>
<EmpName>
<Emp>Sam Abdreson</Emp>
</EmpName>
</Person2>
</ns0:DT_Target>
I am unable to get the output. I am getting the following error.
org.w3c.dom.DOMException: HIERARCHY_REQUEST_ERR: An attempt was made to insert a node where it is not permitted.

JAVA Mapping: Convert a W3C DOM into OutputStream
hi everybody,
how do I convert a org.w3c.dom.Document into outputStream as needed in JAVA mapping?
Thanks regards
MarioHi Mario,
even if you already found the solution, I think the information may be useful to others.
You could do something like:
import org.w3c.dom.Document;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
Document doc;
try {
TransformerFactory tf = TransformerFactory.newInstance();
Transformer trans = tf.newTransformer();
trans.transform(new DOMSource(doc), new StreamResult(out));
} catch (TransformerConfigurationException e) {
// Implement exception handling
} catch (TransformerException e) {
// Implement exception handling

In Java Mapping Whether to SAX or DOM ?
While implementing Java Mapping which of the following SAX , DOM parsers is the most efficient way to implement it.
I mean considering the voulume of data in the XML format is large which usage will give me most optimal performance .
It would be nice if someone could give a sample most optimal java code using JAXP where input stream is read and after processing written to output stream.
regards
Nilesh Taunk.Hi Nilesh,
>>>While implementing Java Mapping which of the following SAX , DOM parsers is the most efficient way to implement it.
there's no one good answer fot this question
except: it depends:)
SAX and DOM are a little different parsers
so it depends what will your java mapping
have to do: if it will change the
structure or maybe it will only change a few tags,
or maybe it will do something else
have a look at the page below to read a simple
comparision between SAX and DOM
http://www.scit.wlv.ac.uk/~jphb/cp2101/week4/XML_Parsing.html
or this thread:
http://www.biglist.com/lists/xsl-list/archives/200301/msg01318.html
they will give you some idea which one to choose
depending on your requirements
BTW
remember use java mappings only
if you cannot use graphical mapping (very easy debugging)
and if your document cannot be parsed (maybe huge documents)
with XSLT which is supported by many graphilal tools

Hi All,
I need Java mapping help. I will get incomming payload as following
<orders>
<matnr>123</matnr>
<qty>10</qty>

i need to change the above payload as follows
<ns0:orders>
<ns0:matnr>123</ns0:matnr>
<ns0:qty>10</ns0:qty>
</ns0:orders>
Please help me how to achieve this using Java mapping.

VijayHi,
Dom will be quite expensive for this type of requirement since you will have to go to each element and then append the namespace.
I suggest you use SAX parser which is more efficient for such requirement.
The code is given below you can modify it according to your requirement.

Hi,
I was trying out a simple Java mapping example.
Example of source structure is -
<?xml version="1.0"?>
<ns0:MT_SRC xmlns:ns0="http://www.sap-press.com/xi/training/00">
<organization>
<employee>
<firstname>Jack</firstname>
<lastname>Rose</lastname>
</employee>
<employee>
<firstname>Paul</firstname>
<lastname>McNealy</lastname>
</employee>
<employee>
<firstname>Vaibhav</firstname>
<lastname>Pandey</lastname>
</employee>
</organization>
</ns0:MT_SRC>
Example of target structure is -
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_TRGT xmlns:ns0="http://www.sap-press.com/xi/training/00"><Organization><employee><name>JackRose</name></employee><employee><name>PaulMcNealy</name></employee><employee><name>VaibhavPandey</name></employee></Organization></ns0:MT_TRGT>

Could anyone please help me out with this?
Thanks and Regards,
ShiladityaHI,
It looks to be that your JavaMap class have one field whihc will be not getting the proper value as input thus its creating the array Index out of bound exception.
Please can you verify if you have assigned the proper String size for all the fields.
Or probably you are getting the blank value which have created the execption.
Also can you narrow down and let me know about the line String.getChars(String.java:672)
Here you have used the try and catch option but may be the exact line no. can give better idea about the problem.
Thanks

Graphical Mapping Vs XSLT mapping Vs Java Mapping Vs ABAP Mapping
Hi Experts,
I have a question regarding different message mapping options available in XI namely
Graphical Mapping
XSLT mapping
Java Mapping
ABAP Mapping
Q1: Which amoung the above mappings is the best and why?
Q2: On what cases Graphical, XSLT, Java and ABAP Mapping should be used?
Q3: Is it true that graphical and XSLT mappings are converted into Java class internally?
Kindly help!
Thanks
Gopal

gopalkrishna baligaHi,
There is no hard and fast rule for using the mapping techniques.
Graphical Mapping is used for simple mapping cases. When, the logic for your mapping is simple and straight forward and it does not involve mult hiearchical mapping requirement. and context handling.
Java and XSLT mapping are used when graphical mapping cannot help you.
When the choice is between Java And XSLT, XSLT is simpler than java mapping and easier. But, it has its drawbacks. XSLT can lead to a bad perfrormance if the Source XML is huge.
Java Mapping uses 2 types of parsers. DOM and SAX. DOM is easier to use with lots of classes to help you create nodes and elements, but , DOM is very processor intensive.
SAX parser is something that parses your XML one after the other, and so is not processor intensive. But, it is not exaclty easy to develop either.
For further info on each of the mapping, refer to these links,

Am not sure about XSLT , but , yes graphical mapping is converted into java classes internally and these classes use SAX parsing as well.

Java Mapping, XSLT Mapping, ABAP Mapping
Hi Experts,
Could any one explain what is the main features of the following Mapping. How to pick the mapping?
Java Mapping - When to use and what is the advantage.
ABAP Mapping - When to use and what is the advantage.
XSLT Mapping - When to use and what is the advantage.
Graphical Mapping - When to use and what is the advantage.
cheers,
SuneeThere are 4 types of mapping in XI
1. Graphical Mapping
2. XSLT Mapping
3. JAVA Mapping
4. ABAP Mapping
When to use Message mapping
1 When the logic for your mapping is simple and straight forward, you can use
Advantages of message mapping
1)Easy to use.
2) has GUI drag and drop.
3) used for simple mapping cases
4) it does not involve any complex logic
Disadvantages of message mapping
1)has limitation in terms of complex hierarchy
When to use Java mapping
1) Java mapping are used when graphical mapping cannot help you.
Advantages of Java Mapping
1)you can use Java APIs and Classes in it.
2) file look up or a DB lookup is possible
3) DOM is easier to use with lots of classes to help you create nodes and elements.
Disadvantages of Java mapping
1)SAX parser is not easy to develop
2)DOM parser is intensive
3) Java knowledge is required
4) bit complexer
XSLT Mapping - When to use
1)When the required output is other than XML like Text, Html or XHTML (html displayed as XML )
2)When default namespace coming from graphical mapping is not required or is to be changed as per requirements.
3)When data is to be filtered based on certain fields (considering File as source)
4)When data is to be sorted based on certain field (considering File as source)
5)When data is to be grouped based on certain field (considering File as source)
Advantages of using XSLT mapping
1)XSLT program itself defines its own target structure.
2)XSLT programs can be imported into SAP XI. Message mapping step can be avoided. One can directly go for interface mapping once message interfaces are created and mapping is imported.
3)XSLT provides use of number of standard XPath functions that can replaces graphical mapping involving user defined java functions easily.
4)File content conversion at receiver side can be avoided in case of text or html output.
5)Multiple occurrences of node within tree (source XML) can be handled easily.
6)XSLT can be used in combination with graphical mapping.
7)Multi-mapping is also possible using xslt.
8)XSLT can be used with ABAP and JAVA Extensions
Disadvantages of using XSLT mapping
1)Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).
2)Interface mapping testing does not show proper error description. So errors in XSLT programs are difficult to trace in XI but can be easily identified outside XI using browser.
3)XSLT mapping requires more memory than mapping classes generated in Java.
4)XSLT program become lengthier as source structure fields grows in numbers.
5)XSLT program sometimes become complex to meet desired functionality.
6)Some XSL functions are dependent on version of browser.
Advantages of Abap Mapping
1) A person comfortable with OOABAP can go for ABAP mapping instead.
Disadvantages of Abap Mapping
1) Abap knowledge is required
2) bit compexer

Different types of Mapping in XI -
Hi All,
After faceing so much of problem, i found that it would be better if i can go for an XSLT/java mapping:
1. It is adding an extra <b>ns0</b> to header line & end line which i dont want to be generated in the output xml file.
2. Namespace problem that basically sticking to 60 but i want 72 characters in my target xml file.
3. No carriage return at the end of each line which is not geting generated through graphical mapping.
Now i have an XSD provided by the client. So how can i use that and which mapping should best suits to solve all these problem.
Should i go for a java mapping or an XSLT/JAVA mapping.
I dont have any idea on both of them, So can you people send me the details for it.
Many Thanks & Best Regards,
JGD.Hi,
Based on the requirement and size we can choose the mapping.
If java is suitable to our requirement then we go for java.
If XSLT is suitable to our requirement then we go for XSLT.
Performance wise(high --> low) :
If data is less then
Graphical mapping -
> Java(sax parser)mapping -
> Java(dom parser)mapping -
> XSLT mapping -
> ABAP mapping.
If data is high then
XSLT mapping -
> Java(sax parser)mapping -
> Graphical mapping(internally it uses SAX)----> Java(dom parser)mapping -
> ABAP mapping.
If you choose XSLT then you can select Altova Map Force tool then no need to write the XSLT code here, it will automatically generates the code.

Can I leverage JDom or Dom4J for java mapping in PI 7.0?
Hi,
since we know that PI 7.0 is based on jdk1.4 which officially allows DOM and SAX,but could I using the open source API like JDom or Dom4J via importing the related jar file to PI IR for java mapping?Anyone tried that?Hi ,
I tried importing jar files into PI7.0 I was able to do so.
First add the external jar file for JDOM into build path in eclipse (or NWDS). I did this in eclipse.
Again I tried to import the same jar file into project within eclipse. Then the jar file will be broken into class files.
Now compile the JDOM code you wrote and do project ->build all. This will generate the class file for your source code in addition to the class files formed earlier. Now exit from eclipe. Move to source folder of the eclipse. there you will find the .java file and the set of class files which were imported into the project earlier. Copy these files to separete folder say "myclass". Now again move to "bin" folder of your eclipse settings and obtain the .class file for the source code you have written. Copy this class file to the "myclass" folder. Now using WINZIP zip all files into one ZIP file within "myclass" folder. Finally import this ZIP into PI 7.0 server. Run the mapping code using test tab. If you are getting any linkage error then you need to obtain correct external jar for JDOM parser else the mapping should run fine.
