Mapping of Java object to ABAP

Hey Guys,
i am facing the following problem. in abap i get a table from a function back. i am copying these values to my outboundcontainer. in java i map them to an array of beans, work with them...
now i want to store them in my database in the backend system. how do i get there values back into abap.
do i have to create a "toString()" function in java and pass a string to abap or do i add each single javavariable into my outbound container?
thank you very much
Philipp

Hi Phillipp,
You can do this by following the reverse steps that you have done to get the values from ABAP to Java.
At the JAVA end :-
1. You can use the "toString" function to get the values from the beans to string format.
2. Append these values into the outbound container giving them "fieldnames" similar to what you did to the outbound container in ABAP to send the values to JAVA.
3. Sync the container to the backend.
At the ABAP end :-
4. Loop at the inbound container and extract these values from it using the fieldnames.
Cheers.

Is it possible to call methods of JAVA objects from ABAP?

Hi all,
Does anyone know if it is possible to call methods of java classes from ABAP?
Regards,

Hi,
Yes we can access the classes of JAVA in ABP.
This is posible from version ECC 6 onward with NETWEAVER atrhcitecuture.
Pls go through this link-

Object-XML Binding: How do I map from java to enumerated xml tags

Hi. I'm new to Object-XML binding and toplink. XML that I'm trying to model in a schema has enumerated elements, e.g. </module_0></module_1><module_n> instead of many </module> elements. To simplify the schema I've opted to use </module> anyway with unbounded cardinality and imported this into a new project.
What I would like to know is if I can use Toplink to map the java object back to the enumerate element types and vice versa?
Thanks for your help.
GeePee

Hi Geepee,
Below is an approach you can use if you have a fixed number of moduleX elements. In the example below X=3.
Assume a 2 object model Root & Module, where Root has a list of Module instances:
@XmlRootElement(name="root")
public class Root {
    private List<Module> module = new ArrayList<Module>(3);
    ...// Accessors omitted
}It is currently not possible to map the items in the module list to the XML elements (module1-module3), but it would be possbile to map an object (see below) with 3 properties to those XML elements:
public class AdaptedModuleList {
    private Module module1;
    private Module module2;
    private Module module3;
    ...// Accessors omitted
}What is required is a means to convert the unmappable object to a mappable one. This is done using a Converter:
import org.eclipse.persistence.mappings.DatabaseMapping;
import org.eclipse.persistence.mappings.converters.Converter;
import org.eclipse.persistence.sessions.Session;
public class ModuleListConverter implements Converter {
    public void initialize(DatabaseMapping mapping, Session session) {}
    public Object convertDataValueToObjectValue(Object dataValue, Session session) {
        AdaptedModuleList adaptedModuleList = (AdaptedModuleList) dataValue;
        if(null == adaptedModuleList) {
            return null;
        List<Module> moduleList = new ArrayList<Module>(3);
        moduleList.add(adaptedModuleList.getModule1());
        moduleList.add(adaptedModuleList.getModule2());
        moduleList.add(adaptedModuleList.getModule3());
        return moduleList;
    public Object convertObjectValueToDataValue(Object objectValue, Session session) {
        List<Module> moduleList = (List<Module>) objectValue;
        if(null == moduleList) {
            return null;
        AdaptedModuleList adaptedModuleList = new AdaptedModuleList();
        int moduleListSize = moduleList.size();
        if(moduleListSize > 0) {
            adaptedModuleList.setModule1(moduleList.get(0));
        if(moduleListSize > 1) {
            adaptedModuleList.setModule2(moduleList.get(1));
        if(moduleListSize > 2) {
            adaptedModuleList.setModule3(moduleList.get(2));
        return adaptedModuleList;
    public boolean isMutable() {
        return true;
}The converter is added to the mapping metadata through the use of a Customizer:
import org.eclipse.persistence.config.DescriptorCustomizer;
import org.eclipse.persistence.descriptors.ClassDescriptor;
import org.eclipse.persistence.oxm.mappings.XMLCompositeCollectionMapping;
import org.eclipse.persistence.oxm.mappings.XMLCompositeObjectMapping;
public class RootCustomizer implements DescriptorCustomizer {
    public void customize(ClassDescriptor descriptor) throws Exception {
        XMLCompositeCollectionMapping originalModuleMapping = (XMLCompositeCollectionMapping) descriptor.removeMappingForAttributeName("module");
        XMLCompositeObjectMapping newModuleMapping = new XMLCompositeObjectMapping();
        newModuleMapping.setAttributeName(originalModuleMapping.getAttributeName());
        newModuleMapping.setXPath(".");
        newModuleMapping.setReferenceClass(AdaptedModuleList.class);
        newModuleMapping.setConverter(new ModuleListConverter());
        descriptor.addMapping(newModuleMapping);

How to pass Array of Java objects to Callable statement

Hi ,
I need to know how can I pass an array of objects to PL/SQL stored procedure using callable statement.
So I am having and array list of some object say xyz which has two attributes string and double type.
Now I need to pass this to a PL/SQL Procedure as IN parameter.
Now I have gone through some documentation for the same and found that we can use ArrayDescriptor tp create array (java.sql.ARRAY).
And we will use a record type from SQL to map this to our array of java objects.
So my question is how this mapping of java object's two attribute will be done to the TYPE in SQL? can we also pass this array as a package Table?
Please help
Thanks

I seem to remember that that is in one of Oracle's online sample programs.

User mapping when installing JAVA addin for ABAP

Hi,
I have installd SAP ABAP on a domain.
As the ABAP went fine and successfully gets installed.
When I am installing JAVA addon for ABAP it is throwing an error lke the users are not mapped.
So can any one guide me where actually I should map the SAP users in a domain.
Prashanth

Your question is very vague, please post the full error.
As this is a java add-in it should user ABAP as datasource so no user mapping should be required.
User mapping is used where java and backend system use different datasources and the naming conventions are different...
Theres not enough information here to give you an objective answer.

How can I call a java object from Web dynpro ABAP application?

I made Web dynpro ABAP application and posted it to SAP EP.
For certain business purpose, we need to call external 3rd party java object using 3rd party's java api in Web dynpro application.
Is there anybody who experienced this kind of java interface issue?
I know Web dynpro Java environment can fully support this kind of requirement. but regarding Web dynpro ABAP, I couldn't find any clue for this.
Any comment or suggestion would be greatly appreciated.
Thanks,
Raymond, ABAP Consultant

if you have jco configured, then you can make calls to java api from ABAP .

ABAP Mapping Vs Java Mapping.

We are implementing a project on XI.
We need to freeze on one mapping.
I feel ABAP Mapping provides the following advantages:
1.SXI_MAPPING_TEST is a very good transaction for debugging and testing mapping environment of XI.Iam not sure wether java mapping can be tested after deploying it on XI.
2.ABAP Mapping is well integrated with the XI and also version control becomes very easy as it is provided by the SAP transport system.
3.ABAP also provides user rich/simple API's as java.
4.Support of XI in ABAP would make sustanenace easy as it is going to be a more SAP product and ABAPers are more available in ERP background.
Java punters,Please provide inputs.

Hi,
all of the step in the message flow after a message enter
the IS will be done by the abbap stack e.g. Receiver
determination, interface determination, ... The only one
step that is executed in J2EE-Stack is the mapping.
In the pipline the system jump from the abap stack to
Java stack to execute the mapping if the mapping is done
in Java (message mapping, java mapping, xslt,...).
But if the the mapping is done by abap the the runtime
has not to jump to the java stack to execute the mapping.
Because there is no java code to execute. To clarif: if
you have only abap-mapping the the compete process step
do not include the jump to the j2ee-stack of XI. So in
this case the abap mapping is more performant cause the
runtime stay in the abap stack through the complete
message processing.
But if you have mix mapping e.g. first step abap and
second step java then the j2ee-stack will be used as
well.

Explicity mapping between ActionScript and Java objects for the BlazeDS Messaging Service

The BlazeDS documentation shows how to explicitly map between ActionScript and Java objects. For example, this works fine for RPC services, e.g.
import flash.utils.IExternalizable;
import flash.utils.IDataInput;
import flash.utils.IDataOutput;
[Bindable]
[RemoteClass(alias="javaclass.User")]
public class User implements IExternalizable {
        public var id : String;
        public var secret : String;
        public function User() {
        public function readExternal(input : IDataInput) : void {
                id = input.readObject() as String;
        public function writeExternal(output : IDataOutput) : void {
                output.writeObject(id);
and
import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;
public class User implements Externalizable {
    protected String id;
    protected String secret;
    public String getId() {
        return id;
    public void setId(String id) {
        this.id = id;
    public String getSecret() {
        return secret;
    public void setSecret(String secret) {
        this.secret = secret;
    public void readExternal(ObjectInput in) throws IOException,
                ClassNotFoundException {
        id = (String) in.readObject();
    public void writeExternal(ObjectOutput out) throws IOException {
        out.writeObject(id);
If I called an RPC service that returns a User, the secret is not sent over the wire. Is it also possible to do this for the messaging service? That is, if I create a custom messaging adapter and use the function below, can I also prevent secret from being sent?
MessageBroker messageBroker = MessageBroker.getMessageBroker(null);
AsyncMessage message = new AsyncMessage();
message.setDestination("MyMessagingService");
message.setClientId(UUIDUtils.createUUID());
message.setMessageId(UUIDUtils.createUUID());
User user = new User();
user.setId("id");
user.setSecret("secret");
message.setBody(user);
messageBroker.routeMessageToService(message, null);

Hi Martin. The way that AMF serialization/deserialization works for BlazeDS is the same regardless of which service is being used, so yes that code will work for messaging as well. On the server, the serialization/deserialization of messages happens at the endpoint. For an incoming message for example, the endpoint deserializes the message and then hands it off to the MessageBroker which decides which service/destination to deliver the message to.
That was a good question. Thanks for asking it. Lots of people are used to doing custom serialization/deserialization with the RPC services (RemoteObject/RemotingService) but I'm not sure everyone realizes they can do this for messaging as well.

When do we go for ABAP mapping and Java mapping

Hi friends,
At present I am working on graphical mapping in XI ,can you guys give me with an example or scenario when do we use ABAP mapping , Java mapping or XSLT mapping.
Thanks in advance
Sud

<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/forums">https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/forums</a>
I have standard XSLT mapping programs available for my scenarios, so use XSLT mapping. Similarly with Java mapping, For most scenarios, message mapping does the job too well. Abap mapping similarly is used to leverge existing ABAP base. If message mapping becomes confusing and hard to follow with too many functions, I go for Java mapping (just my way). I havent used ABAP mapping thus far.
Discussing ABAP mapping
ABAP mapping is developed in ABAP work bench. ABAP mapping needs to be transported to integration server and XI does not support this transport and have to do with ABAP transports.
Customers who can develop mapping program on SAP web AS and can transport them there can use ABAP mapping
*ABAP mapping programs cannot access the value table
*Since ABAP mappings are executed on ABAP stack SAP does not provide any ABAP mapping programs
*ABAP mapping programs must exists with one single version in IS, unlike JAva and XSLT mapping that can have multiple versions of mapping program

Core Data Services in ABAP : No URI-Mapping defined for object type DDLS

Hi ,
When creating a DDL source , I get the error
" No URI-Mapping defined for object type DDLS and object name ZCDSV_01_06".
Can you please suggest what the issue could be?
Thanks,
Chakram Govindarajan

Now I am able to proceed to the next step. Not sure how this started working. However, I get the below error when I open the DDL source editor for one particular ABAP system added in the eclipse environment. I however do not get the error when I open the DDL source editor for another system ( AH4) .I am providing the log error details . I updated the ADT installation. However the issue has not been resolved. Also I tried implementing the Note: 1834948. However I cannot find the option "Team -> Share project..." in the ABAP project.

I just skimmed through your email. You said you
are using WLS 6.1 SP1. Can you try this using
the latest SP. There are many bug fixes done
after SP1.
Web service support in 6.1 is very limited. But, It
looks like 6.1 can handle the case you are trying out.

Blaze DS - Mapping java object into another java application

Good afternoon,
I realized a Client-Server application. Server is Java-based. Client is Flex. Server services are accessible through Blaze DS.
Now I have some Java clients that need to access server services. Blaze DS permits to do it simply but I don't know how to map java objects as I do using [RemoteClass(alias.....)] construct at Actionscript side.
For example, server sends a MyObjectType and client receives an ASObject.
Is there a way to map java MyObjectType automatically at destination?
Thank you for help and sorry for poor english.
Regards, Francesco

xstream will convert any given java object to xml. Not sure what support it offers for schemas.
http://xstream.codehaus.org/

XMl and Java object mapping

I need to map java objects with XMl Node or XML Elements.
My java objets get some attributes, for instance name,color ...
and i need an output like:
<OBJECT_OF_TYPE_XXX>
<NAME>scott</NAME>
<COLOR>red</COLOR>
</OBJECT_OF_TYPE_XXX>
Any idea?
Thanks
Maurice

You can try JAXB which includes a compiler that generates classes based on the XML Schema for your xml structure. It also features the possibility to convert between xml and the generated objects.
Take a look at chapter 9 and 10 at http://java.sun.com/webservices/docs/1.1/tutorial/doc/index.html

JAXB map to java.lang.Object.

Hi people,
I need to create objects using the JAXB xjc tool.
There is an element/attribute in my XMLSchema that needs to be maped to java.lang.Object.
I tried to use anySimpleType this way:
<element name="try1" type="anySimpleType" maxOccurs="1" minOccurs="0"/>Also tried this:
<attribute name="try2" type="anySimpleType" use="optional"/>But this way it maps to java.lang.String.
Thanks for any help, references, sugestions.
Att,
TJ.

Ok, try1 is working, I'm sorry.
Thanks.
