MappingInfoNotFoundException
I need some guidance on this. Not sure if I am missing something. I have
successfully reversed mapped the classes from the Oracle tables for my
schema and was trying to execute a query like this...
Query query = listPM.newQuery (Menu.class, "menukey > 1000");
Collection menus = (Collection) query.execute ();
But I am getting a MappingInfoNotFoundException.

Are your mapping files in your classpath next to your metadata files? Have you
changed the kodo.jdbc.MappingFactory setting?

MappingInfoNotFoundException with one-many mapping to horizontal PC subclass

I have a nasty niggling problem with a one-many mapping where the many

I have another one-many mapping on the "one" class which is fine and is
almost identical to the invalid mapping - it joins on the same
columns/foreign key. The only real difference is that my invalid "many"
side is a horizontally mapped subclass (parent class mapped to different
table). When I took that class out of its hierarchy and mapped it as base,
it works. I don't know why Kodo is saying the mapping for the join is not
found, as the "many" side has an invoice field mapped as one-one. The
superclass does not have a relation to invoice mapped. A slight
complication is that Invoice itself has a persistent superclass persisted
in the same table, but nothing refers to that so I don't think it is
relevant.
Class diagram is roughly like this:
BaseTrade
|
Invoice 1-* Trade
BaseReceipt
|
Invoice 1-* Receipt
Invoice mapped to Invoice table; Trade mapped to Trade table but its
superclass mapped to diff BaseTrade table; Receipt and its superclass
BaseReceipt mapped to Receipt table.
I saw an earlier posting on the same exception that mentioned "collection
element-type" - mine is specified as "Trade", ie the subclass.
Is there any reason why this should not work?
I can provide you with .jdo and .mapping files if necessary.
Many thanks,
AlexAlex-
Can you post your mapping? I just ran a test with a one-many relation to
a subclass of a horizontally mapped class, and it worked fine.
FYI, the example mapping I was using was:
<?xml version="1.0" encoding="UTF-8"?>
<mapping>
<package name="horizmany">
<class name="HorizManyOwner">
<jdbc-class-map type="base" pk-column="JDOID"

<jdbc-version-ind type="version-number"
column="JDOVERSION"/>
<jdbc-class-ind type="in-class-name" column="JDOCLASS"/>
<field name="relation">
<jdbc-field-map type="one-many"
ref-column.JDOID="OWNER_JDOID" table="BUG1174RELATIONSUB"/>
</field>
</class>
<class name="HorizManyRelationSub">

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

So can anybody help me on this why i a getting this error.Booleans cannot by default be stored as varchars. You have to implemnt
your own ColumnFieldMapping which does the transformation for you (since
Kodo does not know if it should be Y/N, T/F, or something else altogether)

The following stack trace appears in my log file when attemping to create

enough, the record, including the embedded password, makes it into the

Thanks for the report. Did you ever run the mappingtool's refresh action
on the Password type? Even though you correctly added
jdbc-use-class-map="none" to your metadata, the mapping tool still needs
to be run on the class and a .mapping file generated (the mapping file
will just record a class-map type of "none"). We'll try to smooth this
out in the future.
I have not run the mappingtool, however I don't have a schema file. I
created the tables, the JDO file, and the XML mapping file by hand. Do I
really need to run this tool? Does it modify Password.class? I am going
off the example in section 7.27 in the Developer's Guide. Is the example
in this section correct and complete? -

MappingInfoNotFoundException on CustomMapping
Hi,
i created a custom Field mapping:
<field name="active">
<extension vendor-name="kodo"
key="jdbc-field-map-name"
value="de.logentis.kodo.YesNoMapping">
</extension>
<extension vendor-name="kodo"
key="jdbc-field-map/column"
value="active">
</extension>
</field>
Of course the YesNoMapping is also existant in my webapp tree. The
YesNoMapping is nearly a 100% copy of the supplied IsMaleMapping from
Kodo. But i get this error log:
[ERROR] - ClientManagerAction.doExecute(41) |
org.springframework.orm.jdo.JdoUsa
geException: No mapping information was found for
"de.logentis.versysng.domain.C
lient.active".; nested exception is
kodo.jdbc.meta.MappingInfoNotFoundException:
No mapping information was found for
"de.logentis.versysng.domain.Client.active
I tripple checked the class and packagenames but everything is in place.
Is there something i forgot?
Thanks
marcMarc-
When you report things like "no mapping found" and "i got mapping
mismatch", we really need the complete error message and stack trace to
be able to help you: without those, we'll only be guessing as to the
source of the problem.
Your particular mapping looks correct, except that I don't think that
you want the "type" extension: that is only means to declare a concrete
type for a field whose declared type is an interface of superclass ...
it doesn't apply to your situation at all.
If you still have problems with this mapping, please post the following
information:
1. The complete error message you receive
2. The complete generated .jdo and .mapping files after you run
xdoclet on the source file

sorry, again me. This "simple" transformation thing drives me nuts. In
this time i would have implemented a distributed transaction strategy ;-)
I checked the docs, applied the example and voila, error:
Here is my xdoclet mapping:
* @jdo.field
* @jdo.class-vendor-extension vendor-name="kodo" key="type" value="char"
* @jdo.class-vendor-extension vendor-name="kodo" key="external-values"
value="true=Y, false=N"
* @jdo.field-vendor-extension vendor-name="kodo"
key="jdbc-field-map/column" value="active"
private boolean active;
This boolean should be stored to a CHAR field in my database. If i run
this, i get "no mapping found". If i put also a "jdbc-field-map" ->
value (which is not documented for the example) i got mapping mismatch.
I checked the samples directory, but there is no external-values example
in there, only the full blown externalisations.
Either i am completely crazy, or you cant copy and paste the example
from the docs (ok its not direclty copy/pasted, but to 80%).
Again, sorry to bother you with that, but i need that boolean->char
conversion thing running :-) Perhaps this is even a DBDictionary issue,
because it seems to be a general mapping i want to achieve.

RC1 and MetaDataMappingFactory
I'm trying to migrate from 2.5.3 to 3.0RC1.
To use only the old 2.5.3 package.jdo file including mapping information
instead of additionally my newly generated .mapping file, I've set
'metadata' as MappingFactory.
Compiling my queries, I get
kodo.jdbc.meta.MappingInfoNotFoundException: No mapping information was
found for "class thisIsMyClass".

If I add a .mapping file with the default FileMappingFactory everything
works fine. The new mapping file was generated with kodo2migrator.
Did I misunderstand the documentation or is this an RC1-error?Did you use the mappingtool to import the .mapping file created with
kodo2migrator into .jdo metadata extensions?I've mapped the mapping information back to the .jdo-files, removed the
mapping files and tried to start again with "kodo.jdbc.MappingFactory:
metadata". Unfortunately it did not work.
I'm using Oracle 9.2.0.1.0.
The only properties set next to metadata are:
javax.jdo.option.NontransactionalRead=true
javax.jdo.option.RetainValues=true
javax.jdo.option.Optimistic=true
javax.jdo.PersistenceManagerFactoryClass=kodo.jdbc.runtime.JDBCPersistenceManagerFactory
If I add the property
kodo.jdbc.SchemaFactory=dynamic
to prevent schema synchronization everything next to a bug I'll report
later works fine. I can read + (partially) write to the database.
Here's the stack trace, the .jdo-files come below:

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".

SriniI solved this problem by removing the identifier field from the

I found what was wrong with this, fixed it and got a different (more

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".

Kodo 3.1.5 - JBuilder X Integration Problem
Hi,
I am a newbie to both JBuilder X and Kodo, but I need to get a legacy application working with that environment (for maintenance purposes).
My issue seems basic, but heck if I can figure it out. I am trying to configure Kodo to work with JBuilder. All I change in the Kodo 3.1.5 Configuration Utility is setting the "Connection Driver" to: "oracle.jdbc.driver.OracleDriver". When I try to save this, I get the following exception:
WARN -- oracle.jdbc.driver.OracleDriver
kodo.util.FatalDataStoreException: oracle.jdbc.driver.OracleDriver

So, it appears that it cannot find the Oracle class (oracle.jdbc.driver.OracleDriver). The ojdbc14.jar is in both my "required libraries" and my "classpath" for the JBuilder Project.
Anyone know what I am doing wrong here?
Thanks, in advance.

No, we didn't try that option, however since the error was restricyed to

just fine. Thanks for the hint, we'll try it. -

Any takers on this one? If its simple, then great.
I currently have a problem making the correct meta-data via xdoclet for a
collection with a many-to-many mapping between an enhanced class and an
xref table (which does not have an enhanced class associated with it.)
Although page 184 of the Kodo JDO 3.01 Developers guide does spell out in
fairly academic terms what has to be done, it still seems fairly
impenetrable, after much mangling and hacking.
As far as I can see the significantly questionable attributes are:-
element-column.<pk column>*
and
ref-column.<pk column>*
The asterisks and the associated texts indicate that these entries can be
specified more than once.
Here is my Meta data.

Here is the basic table which I wish to use for the xref
create table EventConditionConditionXref(
EventConditionId NUMBER(10) NOT NULL primary key,
EventConditionIdGroupTo NUMBER(10) NOT NULL primary key
The EventCondition class and table uses a field 'id' as its primary key.
The intention is the xref table will hold many-many associations between
multiple EventCondition.id instances in the underlying database.
Thus the joing condition would be :
select
EventConditionIdGroupTo
from
EventCondition ec, EventConditionConditionXref ecx
where
ec.id = ecx.EventConditionId
There are numerous variations that I have squeezed through it, but the net

Cheers Ed.Ed-
I think what you want is:
@jdo.field collection-type="collection"
element-type="com.letsys.erespond.business.model.event.Condition"
@jdo.field-vendor-extension vendor-name="kodo" key="jdbc-field-map"
value="many-many"
@jdo.field-vendor-extension vendor-name="kodo"
key="jdbc-field-map/table" value="EventConditionConditionXref"
@jdo.field-vendor-extension vendor-name="kodo"
key="jdbc-field-map/ref-column.ID" value="EVENTCONDITIONID"
@jdo.field-vendor-extension vendor-name="kodo"
key="jdbc-field-map/element-column.ID" value="EVENTCONDITIONIDGROUPTO"
Basically, the "ref-column.<primary key>" specifies the column in the
join table that holds the primary key of the source side of the relation
(the current class), and the "element-column.<primary key>" specifies
the column in the join table that holds the primary key of the
destination side of the relation (the content of the Collection field).
Since it appears that you want the relation to be from Condition to
Condition (i.e., have a relation it itself), the primary key in both
cases will be the 'ID' column.
Let us know if you still have problems with this. You might want to
check out our graphical mapping workbench in 3.1, which helps greatly
simplify composing your mappings.

Horizontal mapping + embedded one-to-one problem
Hi,
this message corresponds to the article "Embedded One-to-One mapping
problem". But this article is more exactly then the first without less
unnessary information.
I got an abstract super-class Person which is mapped horizontal.
Student inherits from Person.
Person contains an attribute called location(instance of Class Location)
which should be mapped "embedded one-to-one".
Since Person is mapped horizontal no table will be used for Person.
I get following exception when running mappingtool on action "buildSchema"
kodo.jdbc.meta.MappingInfoNotFoundException: No mapping information was
found for "xxx.yyy.zzz.persistence.jdo.business.Location.lat"
I think Kodo tries to map the field "location" since the field is declared
as embedded. But it can not embed the field since Person is horizontal
mapped and no table for Person exists where the corresponding field of
Location could be placed in. Also it is not possible to set the "embedded"
attribute in the subclass Student for the field "location" because it must
be specified in the superclass.
Can you help me ?
Thanks a lot,
Felix

Yes, but it seems we did something wrong, fortunely, after defining the
correct CLASSPATH, we've got the mapping files with the right db
structure, however there are some details to correct since when we execute
the application, kodo complains about an int field not being compatible
with a
char column in the db, but the field is defined as char. Here is the error
message :
Caused by: kodo.jdbc.meta.MappingInfoNotFoundException: The "column"
attribute/extension for field "cl.eclac.sca.modelo.Vertice.letter" names a
column "LETTERX" in table "VERTICEX" whose type (CHAR) is not compatible
with the type of the field (INTEGER).
We are using Sybase adaptive Server 12.5. Any hint about this problem
would
be appreciated.
No, we didn't try that option, however since the error was restricyed to
only one class, we converted the field to a String and everything worked
just fine. Thanks for the hint, we'll try it. -
Hi,
Tried to migrate my *.jdo from 2.5.8 to 3.3.1 using ant task
kodo2migrator, which appeared to have worked fine after tweaking with
CLASSPATH. However, when I run the app, that is what I get:
kodo.jdbc.meta.MappingInfoNotFoundException: The "column"
attribute/extension for field
"com.algorithmics.oprisk.bean.org.Org.assetSize" names a column
"ASSET_SIZE" in table "ORG" whose type (VARCHAR) is not compatible with
the type of the field (DOUBLE).
[com.algorithmics.oprisk.bean.org.Org.assetSize
[kodo.jdbc.meta.ValueFieldMapping]]
at kodo.jdbc.meta.Mappings.invalidMapping(Mappings.java:134)
It worked fine in 2.5.8, so why is it not working now?
BrgrdsResolved offline -- Kodo 3.3's externalizer and factory metadata
extensions can convert doubles to strings.

(Kodo 3.3.4) Generics & Xdoclet problem
My development environment is java version "1.5.0_07" on XP Professional, with eclipse 3.2.
I am using annotations via Xdoclet's @jdo to generate mapping metadata for my model objecs. This particular mapping that follows fails with a
<pre>
kodo.jdbc.meta.MappingInfoNotFoundException: No mapping information was
found for "org.foobar.domain.Person.mCollectionOfStuff".
</pre>
The Xdoclet tags are as follows:
<pre>
* @jdo.field
* collection-type="collection"
* element-type="org.foobar.domain.IData"
* embedded-element="false"
* @jdo.field-vendor-extension vendor-name="kodo"
* key="jdbc-field-map"
* value="one-many"
* @jdo.field-vendor-extension vendor-name="kodo"
* key="jdbc-field-map/ref-column.ID"
* value="DATAID"
* @jdo.field-vendor-extension vendor-name="kodo"
* key="jdbc-field-map/table"
* value="PERSON_DATA"
private List<IData> mCollectionOfStuff;
</pre>
When I remove the Generics friendly declaration to the following, it works:-
<pre>
private List mCollectionOfStuff;
</pre>
Does this mean that KODO 3.3.4 does not support Generics ?Laurent,
I'm very sure my build environment is fine. I can compile, deploy & run without the use of generics for the Collection member. However, I will get a compile-time error when I declared the collection using generics.
Thanks
