Mapping Xtext to Java code

I have xtext code:
package dnars.agents{
agent TimeSync {
How to extend AgentClass class in generated Java code like this below?
package dnars.agents;
public class TimeSync extends AgentClass{
I tried with extendedClass in infer but I didn't make it.
def dispatch infer(AgentDefinition agentdefinition, IJvmDeclaredTypeAcceptor acceptor, boolean prelinkingPhase) {
acceptor.accept(agentdefinition.toClass(agentdefinition.fullyQualifiedName)).initializeLater [
extendedClass += typeRef("xjaf.server.agm.AgentClass") //this doesn't work
Thank in advance,
Marko

Hi,
it is
superTypes += typeRef("xjaf.server.agm.AgentClass")
xjaf.server.agm.AgentClass has to be on the classpath of the model file

Re-use message mapping from within java mapping?

Hi there,
I have a question regarding java mapping. What I would like to do is to re-use an existing message mapping from within java mapping.
Technicaly, message mapping is perfomed by com.sap.aii.mappingtool.tf3.AMappingProgram.execute, right? I would like to call that mapping program for a specifc message mapping from within my java mapping.
Pseudo java code would look like this:
public void execute(InputStream in, OutputStream out)
throws StreamTransformationException {
com.sap.aii.mappingtool.tf3.AMappingProgram.execute(in,out,'SomeMessageMapping');
SomeMessageMapping is a message mapping that is defined in the integration repository.
Is it possible? If so, could you provide me with some details?
Thank you and best regards,
Wolfgang

Hi Wolfgang,
very interesting idea?
I would activa a dummy message mapping. than I would have a look in the file directory of the java-stack and try to find out the name of the *.class or *.jar file.
On the other hand you could generate a tpz-transport-file an unpack this file, to explore the name of the *.class or *.jar
Unfortunately I do not have access to the file system. So I can't explore the name.

Java code for calling xslt mapping in module?

Hi,
We have 2 mapping(xslt) in IR
source->cannonical and cannonical->target
we want to remove source->cannonical mapping and want to put that in MODULE of communication channel.
My problem is how to call xslt mapping using java code and we done value mapping their. Did that vallumapping will work in module..
waiting for responce..its an urgent task..
thanq
krishna

You can use the MessageTransformBean to run the XSLT in the adapter framework:
https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/3823 [original link is broken] [original link is broken] [original link is broken]
I do not know, if the value mapping works here. Maybe you just give a try.

How to get the java code of the message mapping

how to get the java code of the message mapping,
I mean to ask how to get the background java code of the message mapping(graphical mapping).
And where to view it?

Hi Satya,
The JAVA code for graphical msg mapping is in below folder:
\usr\sap\<SID>\<DVEBMGS10>\j2ee\cluster\server0\temp\classpath_resolver
Here all the mapping jars are there in this folder.
Just decompile these jars and you can see the code.

Tips on how to write efficient java code for java mapping

hi
I do not have much knowledge in Java
Can anybody tell me some tips on how to write efficient and optimised java code to be used in java mapping
Thanks,
Loveena

hi D'za,
JAVA in xi
A very important place where you will use JAVA in XI is while doing your Mapping. There will be cases when JAVA MAPPING is the best solution to go for. There are 2 types of Parsers available for JAVA Mapping. DOM Parser and SAX parser. Just got through the following links to understand more on Java Mapping and the APIs available.http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/package-summary.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/package-frame.html /people/prasad.ulagappan2/blog/2005/06/29/java-mapping-part-i

New problem -- My java code can't see my CLASSES from Mapping Workbench

Donald and others -
I am VERY new to TopLink......
I was at the last Oracle Developer Days in Northern Virginia. Donald convinced me and my co-workers to use TopLink for our upcoming project. I have been having tons of problems getting it to work correctly. Maybe I need a TOPLINK license plate, like Donald!!!
Here is my newest problem. I can create a DatabaseSession, login to it, write a query and log out of it.
However, I can only do this if I remove my classes from the Mapping Workbench. As soon as I add even one class to the Mapping Workbench......I get an error as follows:
LOCAL EXCEPTION STACK:
EXCEPTION [TOPLINK-3007] (TopLink - 9.0.3 (Build 423)): oracle.toplink.exceptions.ConversionException
EXCEPTION DESCRIPTION: The object [mil.usa.lbit.isr.TestIsr], of class [class java.lang.String], could not be converted to [class java.lang.Class]. Please ensure that the class [class java.lang.Class] is on the CLASSPATH. You may need to use alternate API passing in the appropriate class loader as required, or setting it on the default ConversionManager
INTERNAL EXCEPTION: java.lang.ClassNotFoundException: mil.usa.lbit.isr.TestIsr
Can anyone tell me where I need to put my class files so the java code can see them via the ISR.xml deployment file.
I currently have these files in a .jar file on the system path and in my web-inf folder and in my project settings. I put them everywhere I could think of, but no luck.
Here is my code:
package mil.usa.lbit.isr;
import mil.usa.lbit.LbitColors;
import java.util.*;
import java.math.*;
import oracle.toplink.sessions.*;
import oracle.toplink.tools.schemaframework.*;
import oracle.toplink.exceptions.*;
import oracle.toplink.expressions.*;
import oracle.toplink.queryframework.*;
import oracle.toplink.tools.workbench.*;
public class TestIsr extends ISR {
public DatabaseSession session;
     public Project project;
public TestIsr() {
this.name = "TestISR";
this.color = LbitColors.AMBER;
this.metric = 97.00;
public boolean isConnected() {
if (session == null)
System.out.println("Not Connected");
return false;
System.out.println("Connected");
return session.isConnected();
public void loginToDatabase() {
Project builderProject;
System.out.println("Attempt to login to database using TopLink:");
project = XMLProjectReader.read("C:\\LBIT TopLink\\ISR\\ISR.xml");
session = project.createDatabaseSession();
session.login();
System.out.println("Logged in");
public void runQuery() {
ExpressionBuilder builder = new ExpressionBuilder();
Expression expression = builder.get("isr_id").equal(3);
System.out.println(expression);
//TestIsr isr = (TestIsr) session.readObject(TestIsr.class, expression);
//System.out.println(isr);
public void logoutOfDatabase() {
session.logout();
System.out.println("Logged out");
public static void main(String[] args) {
TestIsr testing = new TestIsr();
testing.isConnected();
testing.loginToDatabase();
testing.isConnected();
testing.runQuery();
testing.logoutOfDatabase();
Thanks in advance.
Donald please email me and maybe we can chat on the phone if you want to offer some help.
Andy

Thanks for the reply!
However, I did try to implement that yesterday.
When I add the "getClass().getClassLoader()" to the "XMLProjectReader.read" call, the codes loses site of my project (.xml) file.
Here is the new line:
project = XMLProjectReader.read("C:\\LBIT TopLink\\ISR\\ISR.xml", getClass().getClassLoader());
Here is the new error:
EXCEPTION [TOPLINK-7099] (TopLink - 9.0.3 (Build 423)): oracle.toplink.exceptions.ValidationException
EXCEPTION DESCRIPTION: Could not find xml project file which is specified in properties file: xmlProjectFile=C:\LBIT TopLink\ISR\ISR.xml.
     oracle.toplink.exceptions.ValidationException oracle.toplink.exceptions.ValidationException.projectXMLNotFound(java.lang.String, java.lang.Exception)
     oracle.toplink.sessions.Project oracle.toplink.tools.workbench.XMLProjectReader.read(java.lang.String, java.lang.ClassLoader)
But my code could find that file before I added the "getClass().getClassLoader()" code.
Maybe I can avoid this problem by "deploying the XML file in my application jar?" Could you please explain more about this option after answering the first part of my question.
Any other posters feel free to help me too.
I know TopLink is a powerful tool, I just keep hitting these hurdles. ARRRRRRRGGGG!!!
Thanks again,
Andy

Pass Map to Java Code

I want to pass a map using Xpress to java code and it seems to be getting error. The java code is suppose to make use of the input hash map, process it, create another hash map and return it back to the calling code. I am having trouble in passing the map created using xpress to the java code (i.e. no problem if i tried to do a similar process by inputing a string and getting a string back)
Sample Xpress code:
===============
<block>
<set name='myInput'>
<map>
<s>First Key</s>
<s>Key 1 Value</s>
<s>Second Key</s>
<s>Key 2 Value</s>
</map>
</set>
<set name='return'>
<invoke name='myMethodName' class='com.Test.ClassName'>
<ref>myInput</ref>
</invoke>
</set>
<ref>return</ref> ==> should get back HashMap created using java code
</block>
Sample Java code
=============
public HashMap myMethodName(HashMap hMapInput) {
HashMap hm = new HashMap();
hm = .....do something with input hMapInput
.....create a new map
return hm;
}

your code looks ok, By the way what error did you get?

How to view the java code of the message mapping,

Hi Experts,
how to view the java code of the message mapping,
how to get the background java code of the message mapping(graphical mapping).
And where to view it?

Hi sowmya,
Open any Message mapping in IR. Press CtrlShift0(zero) to open a new menu.
There you will find an option "Is Java Source Code Available?"
There will be an export button nearby. Use it to get the code.
Open it in a zip , you will see the hide java code.
The JAVA code for graphical msg mapping is in below folder:
\usr\sap\<SID>\<DVEBMGS10>\j2ee\cluster\server0\temp\classpath_resolver
Here all the mapping jars are there in this folder.
Just decompile these jars and you can see the code.

Problem in printing pdf document with java code

Hi All
I want to print a pdf document with java code i have used PDFRenderer.jar to compile my code.
Code:
File f = new File("C:/Documents and Settings/123/Desktop/1241422767.pdf");
FileInputStream fis = new FileInputStream(f);
FileChannel fc = fis.getChannel();
ByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
PDFFile pdfFile = new PDFFile(bb); // Create PDF Print Page
PDFPrintPage pages = new PDFPrintPage(pdfFile);
// Create Print Job
PrinterJob pjob = PrinterJob.getPrinterJob();
PageFormat pf = PrinterJob.getPrinterJob().defaultPage();
pjob.setJobName(f.getName());
Book book = new Book();
book.append(pages, pf, pdfFile.getNumPages());
pjob.setPageable(book);
// System.out.println(pjob.getPrintService());
// Send print job to default printer
pjob.print();
but when i am running my program i am getting error
Exception in thread "main" java.awt.print.PrinterException: Invalid name of PrintService.
Please anybody, knows the solution for this error?
Thanks In Advance
Indira

It seems that either there is no default printer setup or you have too many printers or no printer setup at all. Try running the following code. It should print the list of available print services.
import java.awt.print.*;
import javax.print.*;
public class PrintServiceNames{
 public static void main(String args[]) throws Exception {
 PrintService[] printServices = PrinterJob.lookupPrintServices();
 int i;
 for (i = 0; i < printServices.length; i++) {
 System.out.println("P: " + printServices);
}From the list pick one of the print service names and set it explicitly like "printerJob.setPrintService(printServices);" and then try running the program.

The errors that I am getting are:
1) ERROR: The type Email must implement the inherited abstract method AbstractTransformation.transform(TransformationInput, TransformationOutput)
This is at public class Email extends AbstractTransformation
2) ERROR: This method must return a result of type String
At line public static String getFromEmail(TransformationInput in)throws StreamTransformationException
3) ERROR: This method must return a result of type String
At the line public static String getToEmail(TransformationInput in)throws StreamTransformationException
There seems to be error in declaration.....but I am not able to solve it. So please help me out here
Thanks,

Writing message mapping function in Java in integration repository

Hi XI Pundits,
I am new to XI. I was working on Message mapping in intergration repository.
To map the source messages to target messages, we do graphical kind of mapping like drag and drop.
There are some functions aavilable at the bottom like concatehate, trim and etc. which we use if we need to modify the source message and map to target.
But in case we face a situation when we don't find the function which suits our requirement, I guess we need to write a new function. We can write these new function using Java only.
Can someone throw some light on this ?
What do we do to invoke java editor in integartion reposity to write mapping function in java ?
Can someone give an example of snippet of code ?
Thanks.

Hi Tushar,

Provide the java code for the following scenario.

Hi Experts,
I have tried with all the combinations for this scenario. As per my understanding i require java code for the following scenario
so that it becomes easy........
I require a Message mapping for this Logic.
In the Source there are 4 fields and, the Target side, the fields should appear like this.
Source Structure- File
Record
|-> Header
Order_No
Date
|-> Item
Mat_No
Quantity
Target Structure-IDoc
IDoc
|-> Header
|-> Segment
Delivery_Order_No
Recv_Date
|-> Item
|-> Segment
Delivery_Order_No
Material_Num
Recv_Quantity.
The Logic is for every Order number an IDOC is generated.And if the Material num matches then the quantity should be added. and important note is that the material numbers are different for every order number. That means if a material number is 2 in the order number A. Then the material number can never be 2 in any of the order numbers.Here is the following with an example for the above scenario.
For example:-
we have
Source Structure- File
Order-no Date Mat_No Quantity
1 01/02/2011 A 10
1 01/02/2011 B 15
1 01/02/2011 A 10
2 01/02/2011 C 10
2 01/02/2011 C 10
3 01/02/2011 D 20
3 01/02/2011 D 10
3 01/02/2011 E 25
Target Structure-IDoc
Delivery_Order_No Recv_Date Material_Num Recv_Quantity
1 01/02/2011 A 20
1 01/02/2011 B 15
2 01/02/2011 C 20
3 01/02/2011 D 30
3 01/02/2011 E 25
So for this example total of 5-Idocs created. That means for this example if Order_No is 1 When the Mat_No is A the quantity gets added. For this Scenario 1 IDoc with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) is generated by adding the quantity field in the Target Side. Similarly if Order_No is 1 when the Mat_No is B then separate IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) in the Target Side. Similarly, if Order_No is 2 when the Mat_No is C, an IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) by adding the quantity field in the Target Side. ike wise the process goes on upto 3.Kindly do the needy..
Kindly provide the java code.
Thanq very much in advance..

what i have understood from ur example is that u want to generate an idoc for unique combination of Order-no and Mat_No
if yes then chk the below mapping..
change the context of Order_No, Date, Mat_No and Quantity to Record (right click-> context)
1)
Order-no
----------------------concat[;]---sort----splitbyvalue(valuechanged)-----collapse context---IDoc
Mat_No
2)
Order-no
--------concat[;]---sort----splitbyvalue(value changed)---collapse context---UDF1--splitbyvalue(each value)--Delivery_Order_No
Mat_No
3)
Order-no
-----------concat[;]---sortbykey----------------------- \
Mat_No                       /                            \
Date--------------- /                                       \
----------------------------------------------------------FormatByExample-----collapsecontext---splitbyvalue(each value)----Recv_Date
Order-no                                                 /
-----------concat[;]---sort----splitbyvalue(value changed)
Mat_No
4)
Order-no
--------concat[;]---sort----splitbyvalue(value changed)---collapse context-UDF2--splitbyvalue(each value)--Material_Num
Mat_No
5)
Order-no
-----------concat[;]---sortbykey
Mat_No                       /
Quantity --------------- /
----------------------------------------------------------FormatByExample-----SUM(under statistic)----Recv_Quantity
Order-no
-----------concat[;]---sort----splitbyvalue(value changed)
Mat_No
UDF1:
String [] temp= a.split(";");
return temp[0];
UDF2:
String [] temp= a.split(";");
return temp[1];
