Error using Java Mapping

Hi All,
I am working on scenario with help of this blog for java mapping
http://www.riyaz.net/blog/xipi-java-mapping-demystified/
I am getting error while i test the interface mapping as
Problem while building Tree view
Unable to display tree view; Error when parsing an XML document (Premature end of file.)
How can i solve this error
Regards,
Syed

Hi,
all you need to do is close all the tags properly and try to validate the XML
hope it will work
Regards

N:1 Mapping Possible using Java Mapping?

All,
Is it possible to do a N:1 mapping using Java Mapping?
If yes , how?
Reason for this question is that the execute() of the Java Mapping is going to take the source / request message as the InputStream . In the case of N:1 mapping , as we have multiple messages , how will they be send to the InputStream? Will both the messages be sent combined into the InputStream? Will the MESSAGES tag be embedded into the input stream?

Bhavesh

Hi @ll;
i try the same.
to conduct a java mapping with 2 input structures that fills one target structure.
This mapping is part of a Integrationprocess.
I tested the mapping at the Integration Repository (Interface mapping) with the structure given by henrique and it works fine without any error.
At runtime this structure looks like this (different prefix)
<?xml version="1.0" encoding="UTF-8"?>
<sxi:Messages xmlns:sxi="http://sap.com/xi/XI/SplitAndMerge">
     <sxi:Message1>
          <YOURXML1>...</YOURXML1>
     </sxi:Message1>
     <sxi:Message2>
          <YOURXML2>...</YOURXML2>
     </sxi:Message2>
</sxi:Messages>
As I put it in the Integrationprocess unfortunately a strange error arises.
The trace Workflow-Protocoll shows following error.
<Trace level="2" type="T">Call method execute of the application Java mapping com.endress.infoserve.xi.mapping.MergeConfigStore_IdocOrder </Trace>
<Trace level="2" type="T">Java mapping com/endress/infoserve/xi/mapping/MergeConfigStore_IdocOrder completed. (executeStep() of com.endress.infoserve.xi.mapping.MergeConfigStore_IdocOrder </Trace>
<Trace level="1" type="T">Parsing error after multi mapping.Expected Message<i> instead of IDOC </Trace>
I can't make head nor tail of it.
what´s the mistake?
can anybody please help me?
Thanks in advance
Kind regards

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:
import com.sap.aii.mapping.api.StreamTransformation;
import com.sap.aii.mapping.api.StreamTransformationConstants;
import com.sap.aii.mapping.api.StreamTransformationException;

Hi 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
Gopal

1:n Transformation using JAVA Mapping Scenario

Hi Frnds,
I done a scenario using 1:n Transformation Scenario using XSLT,Graphical Mapping.
But i want to develop scenario Using JAVA Mapping.
Can anybody done the same scenario using JAVA Mapping share the links..
Regards,
Raj Sekhar

You can use SAX parser for this
firstly create a StringBuffer sb object which will store our target output
when startDocument() gets called append the xml declaration in this method
sb.append("<?xml version=\"1.0\" encoding=\"utf-8\" ?>");
sb.append("<Root>");
next for the Test element you have your startElement() method called which will contain the name of your source tag i.e Test
for this , you will need to set a variable boolean isTest to true which was initialised as a false value.
in the characters method you will get the value present in this tag.
test the variable isTest for true value.
if it is true then append the following
sb.append("<Test1>"name"</Test1>"); //name is the buffer passed in characters method
sb.append("<Test2>"name"</Test2>");
sb.append("<Test3>"name"</Test3>");
at the end your endelement() will be called
here reset the value of isTest to false.
in your endDocument()
sb.append("</Root>");
lastly convert to byte[] and then to outputStream format

RFC Lookup using Java Mapping program - Examples

Dear Experts,
I am working on a scenario which is using 1:N mapping. For deciding the target message I have to use RFC Lookup to call the backend ERP system and there are 2 ERP systems involved in this integration. As I am using Java Mapping and never did a RFC Lookup in Java. I kindly request you to give me some examples which I could use for my RFC calls in my Java Mapping. Simple example will do.
Client is adamant to use Java mapping, I could achieve this easily using XSLT or Graphical Mapping.
Advance Thanks,
Pradeep

Hello,
why don't you use Extended Receiver Determination Defining Extended (Dynamic) Receiver Determination - Integration Directory - SAP Library?
What you can do is create a Message Mapping between your source message and Receivers message type. In this message mapping you can use your RFC to generate the target message.
For example, lets say we have the function ZFM_GET_INTERFACE_INFO used to generate the List of Receivers given a source message. You could create a Message Mapping as below:
In this case, the RFCLookup box look as below:
The receiver determination configuration would look as follows:
Afterwards, you will need two specific message mappings for the two ERP systems.
Summarizing, you'll need:
1.- A Message Mapping: Source Message to Receivers Message Type (This one uses the RFC Lookup)
2.- A Message Mapping: Source Message to Target Message for ERP 1
3.- A Message Mapping: Source Message to Target Message for ERP 2
In Integration Directory you'll have 1 Receiver Determination(Source system, Target System determined Dynamically) and 2 Interface Determinations (Source System to ERP1, Source System to ERP2), etc.
I hope you find it useful.
Regards!

XML Structure Conversion using JAVA Mapping

Hi Experts,
I am having a requirement in which i want to convert the contents of source xml structure into a string and map it to the target field.
Source Structure:
<SRC>
<Node1>ABCD</Node>
<Node2>XYZ</Node2>
<Node3>1234</Node>
</SRC>
Target Structure:
<TRG>
<Node1>ABCDXYZ</Node1>
</TRG>
Both the source and target structures are in xml format only.....just the condition is that I have to use Java mapping to achieve it.
The contents of Source node Node3 are not to be mapped.
Since I have very less knowledge of Java it will be very helpful if you provide the complete code to me.
Thanks,
Abhishek.

Hello Udo,
Thank you for reply. It seems ABAP mapping is easier.
What do you think about the idea of using Value Mapping for such conversion task? In this case is it obligatory to use Java coding? And how about performance - will it be better than in case of ABAP mapping, can you say?
Thank you,
Igor

Dynamic file name while using java mapping

Hi All,
i need help.
I am using java mapping to convert xml file in zip file.
Now i need to set output file name as SiteId_TimeStamp.zip.
Site id is comping in xml file.
How can i do this?
I tried many thing but didnt get the solution..
As their is no message mapping so I am unable to use ASMA.
Please help.

Did you check the wiki? You just need to add the code into you java mapping..
Map mapParameters = (Map) transformationInput.getInputHeader().getAll();
   // a) Set Output File name
   mapParameters.put(DynamicConfigurationKey.create("http://sap.com/xi/XI/Dynamic",
                                                         StreamTransformationConstants.DYNAMIC_CONFIGURATION), "");
   DynamicConfiguration conf = (DynamicConfiguration) mapParameters.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
   DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");
   //Depending on your requirement edit this logic. Here, NewDynamicName + CurrentDate will be output file name.
   DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
   conf.put(key, ("NewDynamicName_" + dateFormat.format(new Date())) + ".pdf");

Query on processing a PDF file using Java mapping

Hi All,
i am trying to process a XML and PDF file using Java mapping, it is successful in XML but unable to do for PDF.
below is the code i am using... can any one guide me how to process PDF's..
byte byte1 = 0;
java.io.ByteArrayOutputStream bos = (ByteArrayOutputStream)outputstream;
while((byte1=(byte)inputstream.read())!=-1){
bos.write(byte1);
bos.close();
Thank You,
Madhav

Hi Madhav,
I think instead of going with JAVA mapping you can write a custom adapter module for it.

How to replace namespace tag with new value using -JAVA MAPPING

Hi Guys,
I need to replace namespace Tag in Target xml with a new value.
For Eg: My namespace Tag is - <ns0:TestHeader xmlns:ns0="http://0020.TestHeader.SS.com">
I want My target xml to have value- <ns0:TestHeader>
How can i achieve it using JAVA mapping?
Can you provide me the code to do so.

Sarjana,

Error in Java mapping

Hi~
I am trying to use import statement :
import com.sap.aii.mapping.api.StreamTransformation; in the java mapping.
But I am getting an error saying
"StreamTransformation cannot be resolved to a type"
I am working on the SAP Netweaver STudio SP01. Do I need to load any libraries for the SAP programs ?
I am a newbie with Java. I dont get the direction to resolve this issue.
Good Day~

Hi,
guess Raj is right.

Hi friends,
I am tryin java mapping for first time.. and created one java program using link https://www.sdn.sap.com/irj/scn/wiki?path=/display/xi/wholePayloadtoaXML+field
But when I am compiling it using JAVAC, I am getting following error message that
package com.sap.aii.mapping.api does not exist . How can I solve this error.
Complete error is as follows:

Thanks,

thanks , it is done now..
the program is compiled properly and class file is generated.
but m gettin error in mapping.
in IR i created two message type with data type as string.
and i had imported the class file and java program using Imported archives.
now in interface mapping mapping program i had selected type as Java Class.and name of java program.
but when i tested it, it is giving error as Linkage error occurred when loading class zip/PayloadToXMLField
Please suggest, M i doing some thing wrong?is any thing missing?
Program tht i had used in java
