Hi all,


Until now I used Torque, and I found very usefull the generated constants for Table and Column-names.
Does Hibernate provide such a functionality? In my opinion that is a great help for developers, and is a good practive from
quality assurance point of view.

Best,

Sergiu

you could easily add it to the templates used in the hibernate tools for code generation.

You are right, it should be implemented as a template.
My question was actualy if it is planned to be implemented directly in
hibernate?

I think it will be quite easy to generate for each table/class mapping an Interface that will consist in string constants representing the table and culumn names.

Sergiu

sure - and you are more than welcome to provide a patch.

Generating an interface is actually a good way to do this - then people can choose on their own if they want it *out* or *in* their POJO's

Ok, I will try to d oit in this days, but I have another problem. I was not able to generate the java source code, and I didn't find an internet location to donwload the hibernate-tools source code.

I was creating the following ant script following the instructions from:
http://www.hibernate.org/hib_docs/tools/ant/index.html

<target name="generate-classes">
<taskdef
name="hibernatetool"
classname="org.hibernate.tool.ant.HibernateToolTask"
classpathref="classpath"
/>
<hibernatetool destdir="tmp">
<path refid="lib.class.path"/>
<jdbcconfiguration propertyFile="hibernate.properties"/>
<hbm2java ejb3="false" />
<!-- hbm2java templatespath="src/testsupport/templates"/ --> </hibernatetool>
</target>

When I run the ant target the Exception listed below occurs.
I was looking in hibernate tools package (extracted from hibernate-tools-3.1.0.alpha5.zip) and I ddn't find any Project class in org.hibernate.tool.ant package. Do I have a wrong version of the hibernate tools? I can't find the Project class into the alpha4 version, too.

Best,

Sergiu

I got the following exception when running the java

looks to me like old version of ant.

source code for tools are in cvs see http://www.hibernate.org/268.html

Sory for the previous post, it was my mistake.

It seems that I need to use ant 1.6.5 for running the tasks.

Best,

Sergiu

Finally I was able to run the hbm2java task successfully, after a few trials.

the final configuration I used is:
ant-1.6.2
hibernate3.jar and hibernate-tools.jar bith taken from
hibernate-tools-3.1.0.alpha5.zip

When I used the last available version of hibernate (3.1 beta 3)
I got the following exception.

BUILD FAILED
java.lang.NoClassDefFoundError: org/hibernate/cfg/HbmBinder$SecondPass

Looking into the hibernate package I found that the SecondPass class is not a inner class of HbmBinder anymore. Therefore I found the solution to take
the hibernate and hibernate-tools jars from the hibernate tools realeases.


From those experience one question arises: Wouldn't be better to put the correct hibernate-tool jar into the hibernate releases? (right now it seems to be the other way, the correct version of hibernate can be found in hibernate-tools).

In my opinion hibernate-tools shouldn't be a separate project/jar.

Is is planed to merge the source code of tools into the main hibernate project?

Best,

Sergiu

yes there are plans.

I just implemented this functionality and I created the patch.
How can I submit the patch?

Best,

Sergiu

put it in our jira http://opensource2.atlassian.com/projec ... board.jspa thanks
