System.jdo
When I load my application within the servlet environment, koko is
unable to find my system.jdo file. It is located here:
catalina\webapps\at\WEB-INF\classes\system.jdo
The funny thing is that if I create a package.jdo and put it in the
right place, it finds it fine, such as:
catalina\webapps\at\WEB-INF\classes\
com\almostthere\business\data\package.jdo
Also, when I run kodo from the command-line, and have my CLASSPATH set,
it will find the system.jdo file just fine.
Can you explain why it might be able to find the package.jdo file and
not the system.jdo file within the servlet engine? This one has me
stumped! It was also had to zero in on because the message is a bit
round-about (I'm pasting it in below...). Maybe it could just say it
couldn't find any jdo files... ;-)
Thanks,
Dan

Yes, this is a rather strange problem. It has been resolved in an
internal build, and will be available in our next patch release. As you
noticed, the problem only occurs when loading the system.jdo fine --
other .jdo files load just fine.

Hi,
(my question
Can .JDO files be placed in src folder or some other folder or does it
have to be in the folder containing the class files. )
We have a web application under Tomcat with the structure as
web-inf
-classes
... package structure
- src
... package structure.
Currently we have our .JDO files under the classes folder in the right
package structure. we have individual .JDO file for each object rather
than a package.jdo or a system.jdo (we specify each db column and property
in each file per table)
Can these be placed in src folder or some other folder or does it have to
be in that folder.
when i tried to move the .jdo to the src folder and i tried to enhance an
object, the enhancer said
[java] Enhancing "class Adib.Motiwala.Person"...
[java] Type "Adib.Motiwala.Person" has no metadata; enhancing as
persistence-aware
Please let us know abt this.
Thanks
adib motiwalaThe metadata files must be loadable as a resource from the Classes they pertain to. This is part of the JDO specification. For more information on Java resources, consult the Javadoc for java.lang.Class.getResource() and java.lang.ClassLoader.getResource().
It boils down to this: the metadata files have to be in certain special locations, and those locations have to be in the CLASSPATH. If you put your src/ directory in your CLASSPATH things should work just fine. -

Query Issue with adding a static value
I have written a query in SAP that works the way I need it to. I am going to schedule it so that SAP does a file transfer of the output to another area where the data will be accumulated.
My problem is that I want the name of the system to appear at the end of each line but it is not in any table I can find to match up with the userid.
EX:
UserID Group System
JDOE HR Query Group P201
The field for system is not in any tables but I want to add it and give it a constant/static value all the time in the output.
Any ideas?
Thanks!
Justin Dauby -- SAP Security Analyst
Kimball International Inc.,The name of the system is not in a table, but rather a structure called SYST. You can evaluate it using the system field sy-sysid.
Another option is to call function module RFC_SYSTEM_INFO. The export parameter RFCSI_EXPORT will deliver the system id from component RFCSYSID of the structure RFCSI.

Andrew.Andrew,
It sounds like the username that you are using to connect to the data store
might not have access to read the JDO_SCHEMA_METADATAX table from the JDBC
database metadata. Since you are mapping to an existing schema, you should
not have to run schematool at all -- try just listing all your persistent
types in preferences/properties as described in our documentation instead of
registering the persistent types in the JDO_SCHEMA_METADATAX table.
Additionally, there are a couple of problems with your XML metadata. When
using datastore identity, you cannot use the 'primary-key=true' setting for
a field -- Kodo is responsible for managing the primary key, and you do not
have direct access to it.
If you need direct access to the id fields, then you should use application
identity. Alternately, you can extract the long value from our underlying
datastore identity type, but that requires using Kodo-specific code.

Solved strange problem. Reason: a strange bug?
Hi,
recently I had a really strange problem, where I could not work with the enhanced classes from within a web application (but from the dos-prompt, see my prosting "Kodo says classes are not enhanced ..."). Everybody suggested it was a classpath problem, what I also
thought was the most sensible reason, but all I tried with the classpath didn't seem to work. What I really didn't understand was that it worked before once. I couldn't think of anything that I changed, but now I tried something unreasonable, and it seems to be the reason for
the problem. What I did was, that in the early stages of my application (when everything was still alright) I used a file package.jdo (in the classes-subdirectory) to enhance the classes. Later I changed to system.jdo in the root-dir of the package hierarchie. Now I went back
to package.jdo, and it worked. But I can't imagine how this might change the behaviour of Kodo? The content of package.jdo / system.jdo is this:
<?xml version="1.0"?>
<jdo>
<package name="de.mediateam.quizmaster.data">
<class name="User" />
<class name="Category">
<field name="children">
<collection element-type="Category" />
</field>
<field name="questions">
<collection element-type="Question" />
</field>
</class>
<class name="Topic" persistence-capable-superclass="Category" />
<class name="Test" persistence-capable-superclass="Category">
<field name="participants">
<collection element-type="User" />
</field>
</class>
<class name="Question">
<field name="prerequisites">
<collection element-type="Question" />
</field>
</class>
<class name="Answer" />
</package>
</jdo>
There is no difference if you remove all classes but the User-class. The problem stays when it is system.jdo.
So is this a bug with Kodo, or did I miss something in the documentation about differences between package.jdo and system.jdo?
Cheers
MartinI had system.jdo in the class-hierarchies root directory, but for web-apps this dir (web-context/WEB-INF/classes) doesn't need to be in the classpath. I just tried to copy system.jdo to the same dir as system.prefs and this works.
It might however be helpful in such situations to get a bit more precise error message (not: "The system could not initialize; the following registered persistent types have not been enhanced: [...]").
But thanks for your help. Mysterie solved now.

Perhaps system.jdo is not being found by Kodo? system.jdo should be located
in the same place as system.prefs -- at the top level of the CLASSPATH.
package.jdo files, on the other hand, should be placed in the same package
as the classes they contain metadata for. That is the only difference
between the two.

I don't understand what you mean here. Do you mean that you are trying
to set the ID "just before it is persisted"? How are you doing this

I call paramRuleCondition.setId(new Long(<value>))

One thing I would like to add is that ParamRuleCondition's id has a 'null'
value until just before it is persisted.

I changed the business object method to set the id
But now I am getting a different error
The new error is listed below
One thing I would like to add is that ParamRuleCondition's id has a 'null'

But even then the Id is propogated to ParamRuleConditionExp, from where I
would expect it to go to the ParametricExpValue. But it doesn't happen.
Is my expectation right or is there a gap in my understanding of the way
KODO works?

When attempting to do what you want to do (a persistent class column as

i.e. yourClass.setFeatureId (feature.getId ());
yourClass.setFeature (feature);
Of course that logic can be encapsulated in your business objects.

Kodo newbie seeks explanation of exception occurring during
enhancement. My 'package.jdo' contains mappings for a dozen or so
classes to an existing schema. Most of the classes contain no JDO code
and get enhanced with no problem. Two of the classes are intended for
readonly use; they're sort-of-singletons that initialize all allowable
instances of themselves from storage at class load time. The only
thing that differentiates these classes from the others is their
initialization code. When I run the enhancer over these classes, I get
the following exception:
Exception in thread "main" java.lang.IllegalArgumentException: The
specified class "com.commercehub.
carrier.ServiceLevel" could not be loaded. null

com.techtrader.modules.tools.compiler.ClassArgParser.parseClasses(ClassArgParser.java:65)
at
com.techtrader.modules.jdo.enhance.JDOEnhancer.main(JDOEnhancer.java:80)
Here's the method that contains JDO code: (The JDOFactory mentioned in
the code is the same one distributed with the Kodo tutorials.)
private static void allInstances() {
PersistenceManager pm = JDOFactory.getPersistenceManager();
Extent cln = pm.getExtent( ServiceLevel.class, false );
Query qry = pm.newQuery( ServiceLevel.class, cln );
Collection results = (Collection) qry.execute();
Iterator it = results.iterator();
while (it.hasNext()) {
ServiceLevel nextType = (ServiceLevel) it.next();
String key = nextType.getCarrierString() +
nextType.getCode();
cache.put( key, nextType );
Could I impose on someone with source code to look at the line in
question and suggest what might be failing?
Thanks,

DB name shortening algorithm probably needs more sophistication
Hi,
I think it might be wise to come up with a more sophisticated way to
shorten the names when the class names and field names are too long. I
ran into the following situation with a class called
"AttributeCollection" with a HashSet field called "attributes". The
elements of attributes are instances of "Attribute" a simple persistent
class with a "name" and "value" string. Changing the field name to
"set" fixed it. The only reason that I found the problem relatively
easily is that I remembered observing the shortening algorithm (snip) in
another harmless case.

I had the same problem about a month ago. Patrick Linskey suggested in his post from 12.09.01 "Re: Schematool problem" to "use the 'table' class-level extension in
your system.jdo file". But this didn't seem to work, so I shortened the name of the class to fix it.
Here is Patricks original post:
Martin,
As Joe Mannerling pointed out earlier, the problem that you are seeing
is related to a bug in Kodo's table name generation algorithm. In
order to keep table and column names below database limits (Oracle,
for example, has a 30 character limit), Kodo truncates names to this
length. Unfortunately, it performs this truncation after assembling
the name, so if a class name is over a certain length, then name
conflicts such as those that you are seeing will arise.
We are working on a better name generation algorithm to resolve this
problem. In the mean time, use the 'table' class-level extension in
your system.jdo file:
<?xml version="1.0"?>
<jdo>
<package name="de.mediateam.quizmaster.data">
<... snip ...>
<class name="Question">
<field name="prerequisites">
<collection element-type="Question" />
</field>
</class>
<class name="TextQuestion" persistence-capable-superclass="Question" />
<!-- change this section -->
<class name="MultipleChoiceQuestion"
persistence-capable-superclass="Question" >
<extension key="table" value="MCQuestionX"/>
</class>
<!-- end changes -->
<class name="BooleanQuestion" persistence-capable-superclass="Question" />
<... snip ...>
</package>
</jdo>
Thanks, and good luck.
Cheers
Martin

Contains Queries on Empty Collections

string in one of the two lists. I have done roughly what is outlined below.
1) The class looks like:
public class TestClass
private Vector _collection1;
private Vector _collection2;
2) The metadata in system.jdo looks like:
<class name="TestClass">
<field name="_collection1">
<collection element-type="java.lang.String"/>
</field>
<field name="_collection2">
<collection element-type="java.lang.String"/>
</field>
</class>
3) I construct the query as follows:
// pm is the existing persistence manager
Query query = pm.newQuery();
query.setClass( TestClass.class );
query.setCandidates( pm.getExtent( TestClass.class, true ) );
query.setFilter( "_collection1.contains( string ) ||
_collection2.contains( string )" );
query.declareParameters( "String string" );
Collection results = (Collection) query.executeWithArray( new Object[]
{ "searchString" } );
4) The resulting SQL query (for SQL/Server) looks like:
SELECT DISTINCT
t0.JDOIDX,
t0.JDOCLASSX,
t0.JDOLOCKX
FROM
TESTCLASS__COLLECTION2X t2,
TESTCLASSX t0,
TESTCLASS__COLLECTION1X t1
WHERE
t1.COLLECTION1X = 'searchString'
OR (t2.COLLECTION2X = 'searchString')
AND t0.JDOIDX = t1.JDOIDX
AND t0.JDOIDX = t2.JDOIDX
Suppose that the target string is located in the first collection of some
instance of TestClass. Also suppose that there are no strings in the second
collection. Under these circumstances, the query will not return this
instance.
Is there a way to work around this other than running two separate queries?
Is this a bug or is this the expected behaviour?
Any help on this is much appreciated.

Sasha Haghani.Hi David,
I've tried this approach as well and am now getting a different error.
Using:
1) query filter: "( _collection1.contains( var ) && var == param ) || (
_collection2.contains( var ) && var == param )"
2) parameter string: "String param"
3) variable string: "String var"
4) parameters: new Object[] { "value" }
The following exception raised is:
com.techtrader.modules.jdo.impl.jdbc.sql.SQLExceptionWrapper: [SQL=SELECT
t0.JDOIDX, t0.JDOCLASSX, t0.JDOLOCKX FROM TESTCLASSX t0 WHERE variable =
'value' OR (*variable* = 'value')] Line 1: Incorrect syntax near '*'.

at
com.techtrader.modules.jdo.query.QueryImpl.executeWithArray(QueryImpl.java:3

As you can see from above, the generated SQL statement looks like:
SELECT
t0.JDOIDX,
t0.JDOCLASSX,
t0.JDOLOCKX
FROM
TESTCLASSX t0
WHERE
variable = 'value'
OR (*variable* = 'value')
Additionally, if I change the filter to "( (_collection1.contains( var )) &&
(var == param) )", I get the following exception:
com.techtrader.modules.jdo.impl.jdbc.sql.SQLExceptionWrapper: [SQL=SELECT
t0.JDOIDX, t0.JDOCLASSX, t0.JDOLOCKX FROM TESTCLASSX t0 WHERE variable =

Again, the generated SQL looks like:
SELECT
t0.JDOIDX,
t0.JDOCLASSX,
t0.JDOLOCKX
FROM
TESTCLASSX t0
WHERE
variable = 'value'
We are using multiple queries for now and aggregating the results by hand,
so this issue isn't blocking us.

Sasha Haghani.

Hi Sasha,
One thing that appears "unusual", if you will, about your queries
is that you are using a parameter in the contains() method rather
than a variable. The spec mentions a different usage pattern along
the following lines: "collection.contains(string) && string ==
strParam" where "strParam" is declared as the parameter, and
"string" is declared as a variable. You may have already tried this
as a variation. Your usage appears permitted as far as the spec
goes, but may not have been tested for Kodo.

I tried your workaround and the following exception was thrown:

I tried three variations on the parentheses used in the filterexpression.
All yielded the same exception. I couldn't find any glaring errors or
omissions in the query. The string parameter is also properly declared.Is
this possibly another bug?
I'm executing multiple individual queries to acheive my goal for thetime
being. Let me know if I'm doing anything wrong or if these are bugs,let me
know when they are fixed. Thanks much.

Sasha,
This sounds like a bug. I will enter it into our database and get back
to you later.
Meanwhile, you may be able to work around it using something like
query.setFilter (
"(_collection1.isEmpty () == false && _collection1.contains(string))"
+ " || (_collection2.isEmpty () == false &&
_collection2.contains
(string))" );

I have an enhanced class FileAudit which has a reference to 2 other
enhanced class NetworkOperator and another instance of FileAudit
protected NetworkOperator networkOperator = null;
protected FileAudit rapFile = null;
I persist an instance of FileAudit and then commit. The SQL generated is
INSERT INTO FILE_AUDIT(FILE_SEQ_NO, LOADED, DIRECTION, FATAL_ERRORS, NAME,
AVAILABILITY, PROCESSED, REJECTED, FILE_TYPE, SEVERE_ERRORS, FILE_ID,

'2002-07-30 17:03:04.5'},
Neither RAPFILEX nor KEYSTRING_NETWORKOPERATORX are in my table. There is
nothing in my xml to persist rapFile and the persistence description for
networkOperator is shown below. Where is this coming from???

But the field \'rapFile\' is of type \'FileAudit\', which is apersistence-capable
class. The JDO specification states that all fields of a persistence-capable
type are persistent unless you explicitly mark them otherwise (or unless
they\'re static, final, or transient). So in your metadata for FileAudit you
should include the line:
<field name=\"rapFile\" persistence-modifier=\"none\"/>Thanks, that explains the rapFile field but for the other persistent
capable class field:
protected NetworkOperator networkOperator = null;
I have this in my jdo xml file
<field name=\"networkOperator\">
<extension vendor-name=\"kodo\" key=\"data-column\"
value=\"NETWORK_OPERATOR_UID\"/></field>
NETWORK_OPERATOR_UID is a foreign key in my FILE_AUDIT table that refers to
the primary key in my NETWORK_OPERATOR table which is represented by the
NetworkOperator persistent capable class. -
Bad SQL in 2.3.1 with n*m collection
Hi guys,
This bug comes from an example in my book. The Library example is one of the JDO Learning Tools
that I am providing that allows the user to enter queries interactively. The bug arises in an
example of its use presented in the book. Abe will receive the code with Chapter 8, coming soon.
Basically, Volunteer has a 1 to 1 relation with Borrower. A Borrower has a 1 to M relation with
Book. Book has a N to M relation with Category. Or in object terms, a Volunteer is always a
Borrower, but a Borrower is not always a Volunteer. A Book can be borrowed by one Borrower. A
Borrower can borrow from 0 to M books. A Book can be in the books collection of any number of
Category objects, and a Category can be in the categories collection of any number of Book objects.
Here is the JDO metadata:

Here is the example as presented in the book, this is quoting output from the JDORI.
-- begin quote --
To find all the books that are in categories that interest Harry, use the Book extent, and define
the query variables:
Book b; Category c;
Then use the query string:
categories.contains(c) && (c.books.contains(b) && b.borrower.name == "Harry")
Your answer for the default object population should be:
Found 1 objects in the results

Here is the SQL that KODO produces. It finds many (or all?) books instead of 1.
SELECT DISTINCT

t0.JDOCLASSX,
t0.JDOLOCKX,
t0.BORROWERX,

This has been fixed internally, and will be available in 2.3.3 (hopefully
along with a fix to your other issue).

endThis sounds like a manifestation of
http://bugzilla.solarmetric.com/show_bug.cgi?id=472 to me. Do you have
circular dependencies between classes defined in multiple metadata
files? For example, do you have a class Foo whose metadata is defined in
Foo.jdo, and a class Bar whose metadata is in Bar.jdo, and do Foo and
Bar have references to each other?
If this is the bug, the only current workaround is to put those classes
that have circular references into the same metadata file (a package.jdo
file or a system.jdo file).

Attached is the stacktrace i get during enhancement, inside ant build
process.
Kodo suddenly fails on classes that were enhanced correctly before, so I
guess its some internal bug.
Does anyone know why it happens?
raczer.
I use:
- kodo 2.4.0
- ant 1.5.1

Metadata problem with JSP/servlet application
Hi,
I developed a JSP/servlet test application that makes
use of kodo 2.2.3 STANDARD EDITION for its persitence.
I successfully compile and annotate the application.
I am also able to successfully generate the db
schema with schematool.
Unfortunately, when I run the application using
Resin 2.0.2, Kodo is unable to initialize properly.
Initially it was not able to find "system.prefs" file.
I fixed that by putting "system.prefs" in WEB-INF\classes.
Unfortunately, Kodo is still unable to initialize and
gives the following message:
The system could not initialize; the following registered
persistent types are missing metadata
or have not been enhanced:
[class com.dpov.purchaseorder.PurchaseOrder,
class com.dpov.catalog.Product,
class com.dpov.uidgen.counter.Counter,
class com.dpov.catalog.dao.jdo.CategoryHierarchyEntry,
class com.dpov.catalog.dao.jdo.CategoryHierarchyDAO,
class com.dpov.pricelist.PriceInfo,
class com.dpov.pricelist.PriceList,
class com.dpov.catalog.Category,
class com.dpov.lineitem.LineItem,
class com.dpov.dealer.Dealer,
class com.dpov.user.User,
class com.dpov.customer.Customer].
I use "system.jdo" to describe metadata for the enhancer.
I tried to put it both in WEB-INF\lib and WEB-INF\classes but
it still fails.
Please note that:
1) my classpath variable is not set
2) my application's class file are in WEB-INF\classes
3) kodo jars are in WEB-INF\lib
4) mysql jdbc driver is in WEB-INF\lib
5) system.prefs is in WEB-INF\classes
6) system.jdo is in WEB-INF\classes
Thanks in advance,
Andrea

I fixed my problem by setting the system wide variable (WindowsXP)
CLASSPATH to r:\\dealershop\\WEB-INF\\classes.
