Hibernate complains in derived classes because there are no setters for
normalRange and referenceRanges in class DvOrdered\.

What shall I do about this, is this going to change or do I
misunderstand something?

Hi Bert,

The getters are there\. The setters should be added\.

Thanks, I can add them and see them appear in the repository later

Maybe limitIndex in DvOrdinal is obsoleet, it is not in the documentation\.

setter for property range in class
org\.openehr\.rm\.datatypes\.quantity\.ReferenceRange is also missing, I add
it too\. \\

sorry to tell, also setter for meaning in referencerange missing
now, you are busy ;\-\)

Rong, I think the class DvQuantified also needs a work\-out\.

Following the documentation there should be setters/getters for
properties accuracy, accuracy\(Is\)Percent
Also Magnitude\_status should be added, I believe

Bert

Rong,

I just write them down as I find them, after compare with the
documentation, please don't feel urged, I repair them in my own source\.
Maybe I find some more, please note if I am wrong\. Maybe hibernate 3\.0\.3
is less permissive then hibernate 2\.x was\.

Got exception: Could not find a getter for value in class
org\.openehr\.rm\.datatypes\.quantity\.datetime\.DvDuration

regards
Bert

also setter for value needed in DvTimeSpecification

regards

## Post #11 by @system

getter for value in DvWorldDateTime

;\-\)

## Post #12 by @system

Following the documentation:
I think, ImportedVersion, the property "original" should be replaced by
"item" and appropriate getter/setters added

:\-\)

## Post #13 by @system

void setIsControlled\(boolean isControlled\) \{
    this\.isControlled = isControlled;

  public boolean getIsControlled\(\)\{
    return this\.isControlled;

Hi Rong, and others, I want to ask you to consider following \(at the end
of the email is a question\)\. This is Hibernate3\-related

\- \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
What is the purpose of making a Java\-class "final"?

In my opinion, but I maybe am wrong on this:
It is a formal statement, preventing sub classing, a formal restriction,
for good reasons\.
I don't think there are any advantages in terms of execution\-behavior,
but this is where I am maybe wrong\.
\- \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
Why am I bringing this under attention\.

I get following exceptions \(more/many of them\):

WARN \[main\] \(PojoTuplizer\.java:156\) \- could not create proxy factory
for:org\.openehr\.rm\.datastructure\.itemstructure\.ItemList
org\.hibernate\.HibernateException: CGLIB Enhancement failed:
org\.openehr\.rm\.datastructure\.itemstructure\.ItemList
\.\.\.\.\.\.\.\.\.
\.\.\.\.\.\.\.\.\.
\.\.\.\.\.\.\.\.\.
Caused by: java\.lang\.IllegalArgumentException: Cannot subclass final
class class org\.openehr\.rm\.datastructure\.itemstructure\.ItemList
        at net\.sf\.cglib\.proxy\.Enhancer\.generateClass\(Enhancer\.java:438\)
        at net\.sf\.cglib\.core\.DefaultGeneratorStrategy\.generate\(Default

etc\.\.etc\.\.
\- \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
This brought me to the Hibernate\-faq, where I read this \(another, but
same caused problem, I think\):

I get org\.hibernate\.HibernateException: CGLIB Enhancement failed:
<classname>?
If you use lazy loading with proxies \(default for all classes in
Hibernate 3\), Hibernate needs to subclass your class at runtime\. It
can't do this if you have a private no\-argument constructor\. As per
documentation, at least package visibility is required\.

\(see: http://www.hibernate.org/116.html#A5)
\- \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
Just put lazy load off, it is possible, why not, well I bought a 900
pages PDF about Hibernate3 \(I can really recommend it\. "Java Persistence
and Hibernate"\), in that document I read following, from which one can
conclude that putting lazy\-load off is mostly not wise to do\.
It says:
"Hibernate defaults to a lazy fetching strategy for all entities and
collections\. This means that Hibernate by default loads only the objects
you?re querying for\. Let?s explore this with a few examples\.\.\.\.\.\."
\- \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
Maybe I am misunderstanding something, please explain, else, please
consider following:
Is the directive "final" that important that we want to let Hibernate
run in a suboptimal mode? Or do we change final\-classes in the
repository to normal classes, and urge people not to subclass them?

Or, \(here is a lack of some parts in my knowledge of Java\), is it
possible to use compiler switches, directives, precompiler statements
\(like in C or Delphi\), to maintain both code\-paths in the code?

Thanks in advance for your considerations

kind regards, and have a nice weekend
Bert

## Post #15 by @system

There is another problem connected to lazy\-load\.

There must be a default constructor in every class with
package\-visibility, I think this means public?

It is to avoi this exception:
ERROR \[main\] \(CGLIBLazyInitializer\.java:103\) \- CGLIB Enhancement failed:
org\.openehr\.rm\.datatypes\.quantity\.DvOrdinal
java\.lang\.IllegalArgumentException: Superclass has no null constructors
but no arguments were given
  at net\.sf\.cglib\.proxy\.Enhancer\.emitConstructors\(Enhancer\.java:783\)
  at net\.sf\.cglib\.proxy\.Enhancer\.emit\(Enhancer\.j\.\.\.\.\. etc

I found this information, at
http://www.jroller.com/page/robwilliams/20060413

and I tested it, it works\. I changed the DvInterval default constructor
from private to public, and the exception in that class disappeared\.

As the same as with my previous email \(here below\) I suggest to add the
changed classes to the repository, because, otherwise, Hibernate3 cannot
use lazy\-mode, which makes it unusable, I am afraid\.

I am changing it in my private cpy of the code, and hope to see the
changes appear in the repository

Thanks
Bert

I mean, I have no rights to add code to the repository, Rong, I hope you
make the changes\.

Sorry for providing you in tasks extra

Maybe you do not agree with my point of view, I hope, I learn your
about your motivations, soon, because I am very busy with this and maybe
need to think about your opinions

Thanks
Bert
