[Hibernate] Problems compiling hbm2dao generated code

[Francesco P. <ce...@gm...>]

I'm sorry to post on dev list for this that probably is a user
problem, but i got no feedback on user forum, and google has no answer
for this strange problem.

Hibernate version: 3.2.2
JDK: 1.4

The problem: i was able to generate and compile pojos files with
hbm2java ant target but trying to compile dao interfaces (created with
hbm2dao) i got a bunch of these:

/home/ceztko/development/thgroup/visionehrcv/src/com/thgroup/visionehrcv/model/StatoValutazioneHome.java:99:
cannot resolve symbol
symbol  : method get (java.lang.String,int)
location: interface org.hibernate.classic.Session
            StatoValutazione instance = (StatoValutazione)
sessionFactory.getCurrentSession().get("com.thgroup.visionehrcv.model.StatoValutazione",
id);
                                                          ^

The same error is on all dao classes, all at line 99. My classpath is
ok (surely it see hibernate3.jar, most recent stable version). Trying
to recompile hibernate3 from source, and trying to recompile the
project with all hibernate3 source bundled libs in the classpath give
me the same error.
Looked hibernate sources and get method with parameters String and int
is there, in the org.hibernate.Session superclass! So seems no problem
there too...

Here you can find an example class of the generated sources, pojo
(that compile) and daos (that doesn't), and the config.hbm.xml:
    http://www.webalice.it/ceztko/Provincia.java
    http://www.webalice.it/ceztko/ProvinciaHome.java
    http://www.webalice.it/ceztko/config.hbm.xml

Thanks for your attention. Forgive me if was a my oversight.

Compiled latest version from
http://anonsvn.jboss.org/repos/hibernate/branches/Branch_3_2/HibernateExt
(where appears to be the latest development), and the code is still
uncompilable by jdk 1.4. Unfortunately, i'm constrained to jdk 1.4 for
my project. However, Isn't this a bug (or a regression), also
considering that the default parameter for jdk5 is "false"?

Ok, i can take a look at the dao generation templates (i extremely
need it). If i succeed, i can surely send a patch. But please, can you
point me to the reason it doesn't compile? Maybe i'm blind, but i
can't understand why it doesn't.

This is the incriminated dao interface:

(please note i'm an unexperienced java dev)
I produced the patch (using "svn diff"), at least it compiles now.
Probably the same function toWrapperClass() in BasicPOJOClass.java is
not needed but i didn't understand how it does work getJavaTypeClass
in that class so i was more conservative (you surely know how to cut
it and retain only the version of Cfg2JavaTool.java).

I have 2 more question, if you have time to respond me:
1) Now that compiles, can i trust this interface? Is there some usage
documentation about it (can't found it in hibernate manuals)?
2) I see that a "List findAll()" method is not provided (sort of
"select * from Table"). How can i obtain it in the right (and quick)
way?

For the patch, if it's ok, license is obviously lgpl and i give the
copyright to you.

Thanks,
Francesco
