Currently, the only solution is to ensure that you are using globally
unique IDs. One good way of doing this is to use an application identity
hierarchy that mirrors the hierarchy of the persistent classes, as
described in the documentation at:
http://docs.solarmetric.com/manual.html#horizontal_caveats.

Horizontal mapping with inverse-owner doesn't work

Hi,
We encountered a problem of using inverse-owner with horizontal mapping.
Here is the example.
public abstract class A {
//collection of class T
private Set ts = new HashSet()
public class B extends A {
private String name;
public class T {
private A owner;
private String text;
we use metadata factory. package.jdo looks like this.
<class name="T"/>
<class name="A">
<extension vendor-name="kodo" key="jdbc-class-map" value="horizontal"/>
<field name="ts">
<collection element-type="T"/>
<extension vendor-name="kodo" key="inverse-owner"
value="owner"/>
</field>
</class>
<class name="B" persistence-capable-superclass="A">
</class>
mappingtool gives java.lang.ClassCastException

Fred-
This is a bug in the automatic generation of mappings. See:
http://bugzilla.solarmetric.com/show_bug.cgi?id=1096
Note this this bug only seems to apply to the automatic generation of
mappings: if you manually compose the .mapping file, then you can
express the one-many mapping (provided you can cast it down to a single
concrete type with the "type" extension).
See the bug report page for an example mapping file solution.

Hi,
When using horizontal mappings, you cannot have an inverse type relation
to a horizontally mapped class (there is no table to hold the
inverse!)But that is precisely why we want to use the inverse mapping (to AVOID the
unecessary middle table). Can you explain in a bit more detail why this is
not supported?
Thanks,

mapped to, you can indicate that using the type and element-type
extensions to override the Java declarations to the concrete mapped type.

Horizontal Mapping and Flat mapping with Metadata Value Indicator

Hi
I have an abstract class B which itself extends another abstract class A.
There is no table for A. The fields in A are mapped to B. I believe this
is called "horizontal mapping"
C and D inherit off B. There's a also a table named B (mapped to class B),
but none for C or D. Instances of C and D are recorded in table B. I
believe this is called "flat mapping"
B has a field foo whose possible values are 'fred' and 'wilma'.
If foo='fred', then the record is of type C
If foo='wilma', then the record is of type D
I believe this is called "class indicator" of type metadata.
To express this, I have package.jdo which says
<class name="A"/>
<class name="B" persistence-capable-superclass="A"/>
<class name="C" persistence-capable-superclass="B"/>
<class name="D" persistence-capable-superclass="B"/>
In B.mapping, I have
<mapping>
<package name="domain">
<class name="B">
<jdbc-class-map type="horizontal"/>
<jdbc-class-ind type="metadata-value" column="foo"/>
</class>
</package>
</mapping>
B.java has a private String foo.
In C.mapping, I have
<mapping>
<package name="domain">
<class name="C">
<jdbc-class-map type="flat"/>
<jdbc-class-ind-value value="fred"/>
field mappings for C
</class>
</package>
</mapping>
and similarly in D for value='wilma'
My questions are...
1. Is this kind of mapping supported by kodo?
2. If so, is this configuration correct? I guess not, since I don't
specify the table name anywhere. Where should it go?
3. If I remove the "class indicator" mapping and run a simple test I get
kodo.util.FatalUserException: There is no superclass mapping for mapping
for "class domain.D".

What am I doing wrong?
Thanks in advance

I solved this problem by removing the identifier field from the
class/mapping (kodo support).
Thanks

Do you have two fields mapped to the same column? Did you make sure you

I found what was wrong with this, fixed it and got a different (more
sensible) error. To correct this mapping, I specified B's mapping type as
"base" and gave its table and pk names. Also, I moved the common field
mappings to B.mapping so C.mapping and D.mapping only have fields that are
specific to each.
Now when I run a simple test, I get
testC:
kodo.util.FatalUserException: Attempt to set column "B.FOO" to two
different values: (java.lang.Object)"java.lang.Object@2f608ac2",

Hi
I have an abstract class B which itself extends another abstract class A.
There is no table for A. The fields in A are mapped to B. I believe this
is called "horizontal mapping"
C and D inherit off B. There's a also a table named B (mapped to class B),
but none for C or D. Instances of C and D are recorded in table B. I
believe this is called "flat mapping"
B has a field foo whose possible values are 'fred' and 'wilma'.
If foo='fred', then the record is of type C
If foo='wilma', then the record is of type D
I believe this is called "class indicator" of type metadata.
To express this, I have package.jdo which says
<class name="A"/>
<class name="B" persistence-capable-superclass="A"/>
<class name="C" persistence-capable-superclass="B"/>
<class name="D" persistence-capable-superclass="B"/>
In B.mapping, I have
<mapping>
<package name="domain">
<class name="B">
<jdbc-class-map type="horizontal"/>
<jdbc-class-ind type="metadata-value" column="foo"/>
</class>
</package>
</mapping>
B.java has a private String foo.
In C.mapping, I have
<mapping>
<package name="domain">
<class name="C">
<jdbc-class-map type="flat"/>
<jdbc-class-ind-value value="fred"/>
field mappings for C
</class>
</package>
</mapping>
and similarly in D for value='wilma'
My questions are...
1. Is this kind of mapping supported by kodo?
2. If so, is this configuration correct? I guess not, since I don't
specify the table name anywhere. Where should it go?
3. If I remove the "class indicator" mapping and run a simple test I get
kodo.util.FatalUserException: There is no superclass mapping for mapping
for "class domain.D".

first thanks for your reply,
i already figured that out and deployed it using 10.1.3.1 jars
my question
1) if it is a bug , how come it works fine with jdeveloper (
i would appreciate if you could provide any info about it.
2) i dont want to sound sarcastic , but 10.1.3.1 has of optimistic locking and the recommended solution i found was to use descriptor.getQueryManager().setUpdateCallCacheSize(0);
looks like 10.1.3.1 fixed one bug and introduced other one which was working fine earlier...
is there any other way of fixing optimistic locking issue other than using the
descriptor.getQueryManager().setUpdateCallCacheSize(0);
where i can find the latest/greatest (up to date patched version of toplink)
thanks again for your help

Horizontal mapping not working in Kodo 4.1.2

Hello,
I am having troubles in trying to get the class mapping I want in Kodo 4.1.2.
I want to go from Kodo 3.3 to Kodo 4.1, and still in the evaluation process. Basically, all I want is to have my package.jdo files to work in Kodo 4.1, with the minimum modifications, before moving to JPA.
The mapping is defined is my package.jdo using the <extension vendor-name="kodo" key="jdbc-class-map" value="XXX"/> where XXX can be one of horizontal, base or flat (I dont use vertical in this applicaion). This element does not seem to be properly recognized by the new mapping tool, and all my classes are mapped in the same base table.
After some digging in the docs and in the examples provided, I found this <inheritance strategy="XXX"/> element, that can be put in my package.jdo file. This is not clearly said in the docs (it seems this element is only mentionned in the new orm DTD), but is used in the sample/jdo/horizontal/package.jdo file.
Then I modified my package.jdo files, with this new element, where XXX is one of subclass-table, new-table (with no <join/> nested element) or superclass-table. But the result is not the one expected : all the classes are mapped in the same table.
I then gave a try at the example provided, compiled, enhanced and mapped the sample/jdo/horizontal classes provided with the distribution, since this example covers exactly what I want to do. It seems to me that this example does not work either.
The package.jdo says :
<jdo>
<package name="samples.jdo.horizontal">
<sequence name="sjvm" factory-class="sjvm" strategy="nontransactional"/>
<class name="LastModified">
<inheritance strategy="subclass-table"/>
</class>
The mapping file I get says :
<mapping>
<package name="samples.jdo.horizontal">
<class name="LastModified">
<jdbc-class-map type="base" pk-column="ID" table="LASTMODIFIED"/>
<jdbc-version-ind type="version-number" column="VERSN"/>
<jdbc-class-ind type="in-class-name" column="TYP"/>
<field name="creationDate">
<jdbc-field-map type="value" column="CREATIONDATE"/>
</field>
<field name="lastModificationDate">
<jdbc-field-map type="value" column="LASTMODIFICATIONDATE"/>
</field>
</class>
The enhancement is made using jdoc, the mapping file is generated using the following command line (the DB is empty) :
mappingtool -a refresh -f mapping.xml samples.jdo.horizontal.LastModifiedI would expect an horizontal mapping, with a class element containing only a <jdbc-class-map type="horizontal"/> element, as it is the case if I use my Kodo 3.3 mapping tool.
I tried the enhancement / mapping file generation process with two configuration of the kodo.properties file : the first one with kodo3 as the Mapping Factory and the second with jdo. The result is the same in both cases. I verified by setting the log level to TRACE for the Tool what the factory used. In fact in both case, it is the MappingFileDeprecatedJDOMappingFactory, which seems weird to me.
Bytheway, setting the MappingFactory to jpa leads to the following IllegalArgumentException during enhancement :
Exception in thread "main" org.apache.openjpa.lib.util.ParseException: Instantiation of plugin "MetaDataFactory" with value "jpa" caused an error "java.lang.IllegalArgumentException : java.lang.ClassNotFoundException: jpa". The alias or class name may have been misspelled, or the class may not have be available in the class path. Valid aliases for this plugin are: [jdo, kodo3]
I'd be glad to get any hint if I'm wrong on anything, or any workaround / patch to get my case to work.
Thank you in advance,
Jose

If the same exact app and code works with 4.0 with the same ForeignKeyDeleteAction setting, I suggest that you open a case with support.
This property hasn't changed since 4.0

Horizontal mapping + MappingInfoNotFoundException

Hi,
i got a problem with the mappingtool.
I'am using horizontal mapping.
The abstract superclass Person has an primary key field called id.
Here is the jdo-metadata from package.jdo:
<class name="Person" identity-type="application"
objectid-class="PersonId">
<field name="location" embedded="true"/>
<field name="id" primary-key="true"/>
<field name="kidNames">
<collection element-type="java.lang.String"/>
</field>
</class>
Here is the mapping data from package.mapping:
<class name="Person">
<jdbc-class-map type="horizontal"/>
</class>
I looked at the manual, section 7.6.4.
Thank you
Zach

You have two copies of toplink.jar visible to the application classloader - D:/MOJ_SVN/Lib/toplink.jar should be removed.
For compilation of the application use toplink.jar provided by the server: D:/jdevstudio/toplink/jlib/toplink.jar

Can anybody help on this.
Thanks in advance!!

Hi Sarvesh,
The pdf has details of ABAP mapping. The example given almost matches the xml file you want to be converted.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/xi/3.0/how to use abap-mapping in xi 3.0.pdf
Just in case you have not seen this

Raising Exceptions in XSLT mapping.?

Hi,
When there is an mapping exception, in UDF, i raise an exception...
Similar is the case with Java & ABAP mappings.
Now, How do i raise mapping exceptions in XSLT mapping (Java & ABAP)..?
--DJ

You could use Java enhancement, but instead of just adding info to the trace, you could raise a real exception, using an ErrorHandler object. Ive successfully worked with the one below (not with XSLTs, tho, but I dont see why it shouldnt work.
import java.util.Map;
import org.xml.sax.ErrorHandler;

     public MappingErrorHandler(Map param) {
          trace =
               (AbstractTrace) param.get(
                    StreamTransformationConstants.MAPPING_TRACE);
     public void warning(SAXParseException exception) throws SAXException {

XSLT-Mapping Exception: Prefix not mapped:

Hi all,
I try to make a mapping using XSLT and get the exception: Prefix not mapped: ns0.
I wrote a simple xslt-script:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns1="http://me.home.com">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="//XIFCollection">
<Start>
<xsl:for-each select="ns1:XIFTest">
   <Found>
    <xsl:number format="1"/>
   </Found>
</xsl:for-each>
</Start>
</xsl:template>
</xsl:stylesheet>
Using this input XML:
<?xml version="1.0" encoding="UTF-8"?>
<XIFCollection >
<ns0:XIFTest xmlns:ns0="http://me.home.com">
<IFControl>
   <MeldungsId>1</MeldungsId>
</IFControl>
<XTest>
</XTest>
</ns0:XIFTest>
<ns0:XIFTest xmlns:ns0="http://me.home.com">
<IFControl>
   <MeldungsId>2</MeldungsId>
</IFControl>
<XTest>
</XTest>
</ns0:XIFTest>
</XIFCollection>
In XML-Spy I get the following output:
<?xml version="1.0" encoding="UTF-8"?>
<Start xmlns:ns1="http://me.home.com">
<Found>1</Found>
<Found>2</Found>
</Start>
What I expected.
But using XI or the XML-Toolkit XI30xslt I get the exception:
java.lang.Exception: XMLParser: Prefix 'ns0' is not mapped to a namespace.
I tried everything and searched all dokumentation but have no idea.
Anyone with an idea?
Thanks

Hi,
you need to chage as Udo said
but also the other ns0 one:
check this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns0="http://me.home.com">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="//XIFCollection">
<Start>
<xsl:for-each select="ns0:XIFTest">
   <Found>
    <xsl:number format="1"/>
   </Found>
</xsl:for-each>
</Start>
</xsl:template>
</xsl:stylesheet>
BTW
it works in Stylus Studio now

michal

Question about Logon ticket with user mapping at BI-JAVA environment

We're implementing BI 7.0 including BI Java and SAP EP for end user
access.
I have two question about SSO method when we're using BI Java.
I know we can simply configure SSO logon ticket with BI-Java(EP
included) and BI-ABAP through BI template installer and we already
succeeded in that case.
But the problem is we want to change it to user mapping SSO method for
some our internal reason.
After we configure user mapping SSO, we've got SSO failed error when we
call BI-Java stuff like BEx Web Application iView.
After many testing implemented, we found SSO Logon ticket with user
mapping (using SAP reference system). It seems working now.
But our question is "Is it no problem when we use SSO logon ticket with
user mapping?" Is there any restriction or issue?
One more question is we can ONLY use user base mapping when reference
system used. How can we assign BI-ABAP users to EP Group?

Using an SAP Reference system is allright. But if the reason u r going for this is because of different usernames in EP and BI, why dont you go for user mapping.
Anyways, on restriction of reference syetms is that you can have ONLY ONE reference system defined in portal. In you case you can only have the BI system defined.
Hope this helps!!

Problem with Java Mapping

Hello experts,
I developed a Java Mapping Programm for reading filename of a pdf file and giving filename to a rfc structure for calling a rfc module. Thus, I test it via testing interface method and implementing a main method in my mapping class, which works, but if I run it in the integration server I get the following exception:
MP: Exception caused of com.sap.aii.af.ra.ms.api.RecoverableException: java.lang.StringIndexOutOfBoundsException: String index out of range: -7: com.sap.aii.af.rfc.afcommunication.RfcAFWException: java.lang.StringIndexOutOfBoundsException: String index out of range: -7
That is the execute method of my class:
     public void execute(InputStream inputStream, OutputStream outputStream)
          throws StreamTransformationException {
          // TODO Auto-generated method stub
          try { //The following is for the FileName in the File Adapter
               DynamicConfiguration dynamicconfiguration =
                    (DynamicConfiguration) map.get("DynamicConfiguration");
               DynamicConfigurationKey key =
                    DynamicConfigurationKey.create(
                         "http://sap.com/xi/XI/System/File",
                         "FileName");
               String myFileName = dynamicconfiguration.get(key);
               MappingTrace trace = null;
               trace.addInfo(myFileName);
               DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
               DocumentBuilder db = dbf.newDocumentBuilder();
               TransformerFactory tf = TransformerFactory.newInstance();
               Transformer transform = tf.newTransformer();
               Document docout = db.newDocument();
               Element root = docout.createElement("Z_SD_WEB_HP_INVOICE_STATUS");
               root.setAttribute(
                    "xmlns:ns1",
                    "urn:sap-com:document:sap:rfc:functions");
               docout.appendChild(root);
               Element docName = docout.createElement("IM_DOCNAME");
               root.appendChild(docName);
               Text srcxml = docout.createTextNode(myFileName);
               docName.appendChild(srcxml);
               DOMSource domS = new DOMSource(docout);
               transform.transform((domS), new StreamResult(outputStream));
          } catch (Throwable throwable) {
               throwable.printStackTrace();
If I test via main method and testing interface mapping the generated xml is like:
<?xml version="1.0" encoding="UTF-8" standalone="no"?><Z_SD_WEB_HP_INVOICE_STATUS xmlns:ns1="urn:sap-com:document:sap:rfc:functions"><IM_DOCNAME>232132.pdf</IM_DOCNAME></Z_SD_WEB_HP_INVOICE_STATUS>
I do not understand why I get this error in real environment.
Kind regards,
Erkan

Hello experts,
I found the solution. I will also publish this solution, this is also a point which I sometimes missing here in this forum:
In creating the rfc-xml with java mapping, so a prefix should be add to the name of the rfc-structure e.g.
ns1:Z_RFC_CALL. If this prefix is missing, then you get this error:
com.sap.aii.af.ra.ms.api.RecoverableException: java.lang.StringIndexOutOfBoundsException: String index out of range: -7: com.sap.aii.af.rfc.afcommunication.RfcAFWException: java.lang.StringIndexOutOfBoundsException: String index out of range: -7
To find this I create a grafical test mapping and I check the test rfc-xml with the java created xml.
Anyway thanks all for the published recommendations.
Kind regards,
Erkan
