Help wanted to improve tools

max · **Posted:** Mon Oct 17, 2005 8:26 am

Hi,

As an experiement I have added a "Help Wanted" option for the jira issues in the tools project.

I'll set that option if I feel the feature is something that would fit well for community user contributions, in other words its a feature that is either very simply/welldefined and doesn't require indefinite knowledge nor time and/or its something that would be nice to have but just isn't on the current roadmap for the core team.

So if you feel like getting your hands dirty then go see at the following link and pick something up ;)

http://opensource.atlassian.com/project ... stId=10545

(of course there is probably 1000 other things that could be improved/added and you are more than welcome to contribute that too ;)

Apparently that view was not globally shared - it is now.

Hi max:

Why the Hibernate Tool current release(reverse engine) don't support many-to-many mapping? It is important in our project. I mean that I have three tables in database ,I want to create two java class other than three. I think the hibernate tool should add this feature to next release.

interesting you should post this in the "help wanted" section :)

(anyhow if you followed jira you would see i completed many-to-many support for the core tools engine last week)

Thanks, Maybe I could download the nightly build from cvs and build it. ;-)

Hello

I thitnk that is simple.

first, the disappointment issue...
my objects use commons lang to implement toString().
I forgot point to common-lang.jar on edit configuration dialog.
When I retrieve entities on simple query eclipse "self-muder against the wall". It shows error message box infinitely . Ok button close it but new message box opens instantly. As result I cant corect close eclipse, and forced to shoot it. As result I loose my configuration \.metadata\.plugins\org.hibernate.eclipse.console\hibernate-console.xml-16
I think that it is trivial to catch and handle tihs exception.

second, is cosmetic issue...
Why I can't point to properties files when configure class path. as example, this feature required for configure OScache. There is a question: "Why session configuration isn't simple file in workspace as hib.cfg.xml?" and why it not aligned for comfortable editing.

thanks

what are you referring to ?

If you could put this in a jira issue with infomration about when and what the error message contains then I would have a chance of fixing it.

Because it is the users classes I have to load and instantiate I can't always control/enclose their behavior; but I can do it in most cases and there might be place were I did not guard it enough....to find those I need bugreports about them (or accidently bump into them my self)

Again, if users aren't telling me what is going wrong I can't really fix it.
(note; the issue about loosing the config file is in jira and i'm looking into it)

I don't understand how adding a non zip/jar *file* to the classpath can ever make sense ?

original reason: a hibernate console configuration can be used by many projects.

in the future we will loosen this up and make it possible to have "local" definitions.

p.s. these questions should be in a seperate more apropriate thread and/or jira and not under the thread that is looking for people contributing patches :)

Thanks.

Hi,

I have played around a bit adding support for pocso(?) :-) generation. In essence a new interface was added (LangExportContext.java) which is now responsible for specific target language features, and some csharp specific templates.

Existing Hbm2JavaTest.java tests seem to run unaltered (at least with an Oracle database as the backend), and a new one (Hbm2CSharpTest.java) was added to test csharp generation. Some duplication between Cfg2Java and ImportContext has been moved to the new classes.

There are still thinks missing (e.g. java annotations - csharp attributes mapping and adding the [Serializable] attribute in csharp classes) I am still working on.

If you are interested in seeing some code, let me know where I should upload the zip file.

Thanks
