Java Mappings Basics

Hi!,
I am new to SAP XI....I am comfortable with certain scenarios...I know Java...not an expert though, but can try to understand...I want to learn Java Mappings from the basics....i.e., start to finish... Can anyone help me with this.....with all screenshots and step by step instructions.....
Also, I am looking for a job in SAP XI......How do I have to proceed....Also, please explain the format, specifications of a project so that, I'll have some idea about it....

RESOURCE_NOT_FOUND for XSLT and Java Mappings (SXMB_MONI)

Experts,
I need your opinion / experience about a problem that we have been facing here:
XI 3.0 was upgraded to PI 7.0, but since then all interfaces that uses XSLT and Java Mappings throws a RESOURCE_NOT_FOUND error in SXMB_MONI only in the production environment.
We found SAP Note 951318 that describes exactly the scenario we have here. The note also inform that the issue is solved at SP 07 (for PI 7.0).
The problem is that we find out that abap and java instance are with different SP ( SP 13 for abap and SP 09 for java) after XI upgrade to 7.0, since they had a error at java instance.
Have anyone of you facing with this problem?
I believe that even having a SP greater than 07 (as sap note 951318 requires), as we have an difference between abap and java SP, this issue might have been causing the problem.
Points will be given.
Regards,
Daniela

Yes, thats true. As you can see,
In XI 3.0 (SAP Netweaver'04), the issue is solved in:
           SP 18,
           SP 17, patch 1 (archive SAPXITOOL17_1. sca for XI Tools)
           SP 16, patch 4 (archive SAPXITOOL16_4.sca for XI Tools).
you need to import and put a patch if you are using XI 3.0. but in your case it is PI 7.0.
So please check out the SAP Note : 950608 and download SP 07,patch 2 (archive SAPXITOOL07_2.sca for XI Tools).and Note 952402 .

Creating java mappings

Hi Experts,
Is there any tool available for creating java mappings in XI given a source and target message. I have seen for XSLT mappings there is a tool called stylus studio, which has some kind of graphical tool to create the XSLT mapping between a source and target XML message.
thanks
sankar

Hello Sankara,
The message mapping tool is aimed for that. When the mapping is drafted using this tool and executed it internally creates a java program corresponding to the mapping, which then gets executed.
Thanks & Regards

How to get Message IDs in Java Mappings

Hello,
in PI 7.1 Java mappings the way of getting the trace object has changed from:
trace = (AbstractTrace) param.get(StreamTransformationConstants.MAPPING_TRACE);
to:
getTrace();
Because the Java mapping class definition changed from
implements StreamTransformation
to
extends AbstractTransformation
Is there something similar to get the message ID or do i have to use the old way:
public void setParameter(Map param) {
     this.param = param;
     if (param == null) {
          this.param = new HashMap();
String MessageID = (String) param.get(StreamTransformationConstants.MESSAGE_ID);
Thanks and best regards,
Benjamin

I found an easyer way:
TransformationInput.getInputHeader().getMessageId();
But your reply brought me on the right track!
Thanks.

Java mappings ?

Hi,
I need some information regarding java mappings in IR.
How to Test and Debug Java Mappings?
Thanks in advance,
siva.

HI
Usually Java mapping is preferred when the target structure is relatively complex and the transformation cannot be accomplished by simple graphical mapping.

JAXB as standard API for Java Mappings in XI?

Hi there,
Has anyone on this forum implemented Java mappings in XI using JAXB (reference implementation for XML/JAVA data bindings of SUN)?
If Yes, can you please share any experiences?
We're considering to use this API for Java Mappings in XI but first would like to get more background info.
Cheers,
Rob.

Hi Roberto,
Have tried implementing Java mapping using JAXB technique couple of years ago. However I was not able to test the mapping in XI/PI environment.
<ul>
<li>There is no in built support for JAXB from SAP XI.</li>
<li>There is no documentation available from SAP on JAXB hence it is difficult to implement the mapping.</li>
<li>We have to import JAXB specific jars along with the mapping code. my attempt to execute the mapping test in IR tool was unsuccessful It was running fine in standalone mode in local PC </li>
</ul>
[My question on SDN on same topic..|Java Mapping Using JAXB [Java Arch for XML Binding];
Thanks and regards,

"java Web Service from WSDL" just hands me a SOAPElement, no java mappings

Another beginner question. I've used jdev and built a WSDL starting from a somewhat complex xsd. I've used the wizard "Java Web Service From WSDL" taking defaults. It seems to correctly generate class files for all my xsd types. It produces a fancy looking java-wsdl-mapping.xml But the generated stub service implementation just gets handed a SOAPElement object. Why generate all that mapping stuff and then make me parse the incoming data myself with SOAPElement methods? How am I supposed to make use of the mapping work that the wizard seems to have done for me?
Thanks,
Steve

Dear Tugdual,
Thanks for your intrest in my issue. I narrowed it down to the following type in my xsd
<complexType name="PersonInfoType">
<sequence >
<element name="FamilyName" type="string"/>
<element name="IndividualName" type="string"/>
<element name="SpouseName" type="string"/>
<element name="BirthDate" type="dateTime"/>
</sequence>
</complexType>
This works fine - the "WebSerice From WSDL" wizard "knows" how to generate a class for PersonInfoType (with geters and seters) as well as useful stub implementation:
public class PersonInfoImpl {
public PersonInfoType processPersonInfo(String entityCode) {
return null;
However, if I make my type multiple occuring (to represnt e.g. rows from a db)
<complexType name="PersonInfoType">
<sequence maxOccurs="unbounded" >
<element name="FamilyName" type="string"/>
<element name="IndividualName" type="string"/>
<element name="SpouseName" type="string"/>
<element name="BirthDate" type="dateTime"/>
</sequence>
</complexType>
Now the Web Service generator runs, but just doesn't generate any PersonInfoType class at all. For a stub implementation it genertes the following:
public class PersonInfoImpl {
public SOAPElement processPersonInfo(String entityCode) {
return null;
Now I'm stuck with the container just expecting from me a Soap Object and I have to build all the pieces myself with no java mappings to my xsd at all. Not very useful.
Is there another xml structure I can use to represent data rows that is better supported by the wizard?
Thanks,
Steve

Java Card Basics

Hello People
This is my first time working with Java Card and any other smart card related stuff.
So I read the 3 parts of "An Introduction to Java Card Technology" and other two articles there.
I have serveral inquires about the issue.
Is the STK the same as sim.toolkit ? or is it a proprietry kit for each smart card manufacturer ?
What is sim.toolkit ? is it different than what java card provides ?
What I want to do is an applet on a SIM that sends encrypted SMSs.
I read that java card applets are passive, does that mean when the applet is installed on the SIM,
another app (probably J2ME) must activate and run it ?
In my project, do I need to use sim.toolkit.* for SMS capabilities or java card got that?
Exucse my ignorance in the matter, any help is appreciated,
Regards

So, no one is familiar with Java Card basics to clear some stuff for me ?

Java code samples for java mappings

Dear all,
Can you please send me a sample scenario in which you used the java mapping.
How do we assign the source structure,the target structure.
How do we map source->target
Do we give the source and target interface names in execute method)?
if so where do we map the same.
we have one to one mapping in graphical,message mappings which i worked with.
is there any tool for making the same thing in java?
Kindly send me the documents if any on java mapping to [email protected]
Please clarify.....

Java Arrays basic

i want to ask a basic question which i don't know..
Employee[] emp=new Employee[10];
System.out.println(emp.length);
in the second line, we are using length variable..
i want to know, from where 'length' is coming?
in which class it is defined?
Thanks in advance...

Yes...
In the Java programming language arrays are objects (§4.3.1), are dynamically created, and may be assigned to variables of type Object (§4.3.2). All methods of class Object may be invoked on an array.
this is the very 1st line of the documentation...sometimes reading documentation is helpful (I know sometimes its boring too...)
have you checked ArrayList? its pretty impresive ... lol
ArrayList<String> arr= new ArrayList<String>();ArrayList is a growable Array.

Calling an EJB from Java Mappings in PI 7.1

In my operation mapping, I am using a Java class which in turn invokes an EJB using JNDI lookup.
When I execute the code, the class is successfully finding the EJB using JNDI, but invoking it I am getting a java.lang.NoClassDefFoundError.
If, I add the class it cannot find to the jar containing the Java mapping class, I get a java.lang.ClassCastException.
Has anyone been able to call a custom EJB from with a Java Mapping class?
Any help appreciated.
Thanks.

Java Array -basic

What i want to do is, to read a text file and split it from a given character and save it on to an array
the format of the text file is :::
shyu#name_lackty+
shtyyu#name_lackty
shtyyu#name_lackty
shytyyu#name_lack
shytytu#name_lacktyty
shytytyu#name_lacktyt
I want to split from "#" character, and save the first part of the sting (shyu) in an array called Array1 ... and the second part of the string in an array called Array2(name_lackty) ... like wise the code should read all the lines in the text file and save the 2 set of strings in its respectable Arrays...
So i could access by calling it ... like Array2[3] will have "name_lack" saved in it... and Array1[1] will have "shtyyu" in it...
but what i get is,the result of the last record of the file.. y is this ? how do i alter my code ???
I tried coding this and i came across a problem.. in my code, its only splitting one line, and not reading through all the lines of the text file.. i have been trying this for days, and still have no hope of fixing it..
can some one help

    String strLine;
    int count=0;
    String array1[]=null;// stores the first set of the string after splitting
    String array2[]=null;// stores the second set of the string after splitting
    while ((strLine = br.readLine()) != null)   {
      array1 = strLine.split("#");

Hi
Used this examples in my Login.java bean.
I received a Long String back e.g
CN=Name Surname,OU=Users,OU=Policy Exclude: null:null:{displayname=displayName: Name Surname, cn=cn: Name Surname}
and I only need the first part (CN=Name Surname)
So
Declare 4 variables
private static final String stringDelimeter = ":";
private static final String stringDelimeters = ",";
private long counter = 1;
private String newname = null;
then wrote a method
public static String getDisplayName(String name){
String returnStr = null;
int count = name.indexOf(stringDelimeter);
int counter = name.indexOf(stringDelimeters);
returnStr = name.substring(0 + 3, counter);
return returnStr;
After returning returnStr I did this
newname = getDisplayName(sr.toString());
Use this logic in a loop
let me know

Java Mail Basics

I was wondering about the 'from' field in sending mail.
How does this work for a stand alone e mail server written in javamail?
Do I need to get some sort of domain name to be able to recieve email?

The FROM address identifies the sender of the email.
Javamail is a Java API for performing mail related operations. Generally you would implement mail CLIENTS using Javamail. The email service itself would be provided by a separate product.
You can specify a value for 'RCPT TO' field when you send email. Replies to the sent email will be routed to the mailbox associated with the email address you specify in 'RCPT TO'.
For local testing purposes, you can install a light weight mail server and configure some mail accounts in it. I do not remember names of any freely available ones off hand. Will post another message if I find some.

Java environment basics

1) what does the jdk contain ?
2) what is the JRE ?
3) what is the java console / plug-in app ?
4) what is the java web start app ?

Mqtt and java to basics iot(s) projects

Hi,
I have a adapted googlecreative Project running in my house. Is this use node.js, websocket, html5, but is don't have a public access (DDNS) and I'm not have a mobile app for it yet. I will have a dyndns address..
Now, I'm wanting to use MQTT and solve this problem.
What do you thing about Eclipse Paho and MQTT (Java Messaging in the internet of the things) ??
e.g.: hardware : raspberry pi and arduino uno r3

Another possibility is NewJawin. You can also take a look at Jakarta POI,
but that's not really implemented. There's no good solution, but Jacob and
NewJawin are the two best I've found.
