I'm a newbie at this... *please* be gentle! I feel stupid enough already! :)

I'm getting the "JDBCBinderException" error, too, but I *think* this is different than the other flavors of this error that I've seen in the forums already. In my case, I'm using Sybase (not Oracle), I've set the default_schema and default_catalog, and I'm excluding unneccessary tables in my reveng.xml with a big-bad "exclude everything" at the end of the file.

I'm generating the *.hbm.xml files using an hbm2hbmxml ant task, and generating the POJOs using an hbm2java task.

Here's some stuff from an example... sorry for all the crap here. I wanted to include enough, hopefully it isn't *too* much...

===============================================

I can add in the DDL for the MARKET_CONTROL table, too, if you need it.

Any ideas? I'm stumped. :( I've tried manually overriding some things in the reveng file (e.g., create a table name="MARKET_CONTROL", and specify things like the primary key directly), but that doesn't seem to help.

Thanks!

The mapping file shows your using marketid as the primary key and marketcontrol as fkey for a set mapping to AccountMaster. I agree it should not die like this and have a decent error message but the cause could be that AccountMaster is not included in the tables to process.

Try adding/enabling it in the reveng. If this can be confirmed then JIRA entry should be created so that if the target in the association is not in the list of allowed tables just the property alone should be generated (in this case only the primary key mapping).

i think the issue is that you are using jdbcconfiguration + also includes and already existing mapping of that class and thus confuses hibernate.

Why do you have that fileset in there under <jdbcconfiguration> ?

Max - yup, I think you nailed it. I switched my hbm2java task back to using a plain old <configuration> instead of a <jdbcconfiguration>, and it seems to be happy again. I don't remember why I did that... must've been something I tried while I was thrashing helplessly to fix a separate problem (below):

Our database schema kinda sucks, and we have FK's which refer to other tables with compound PK's, and the FK constraints don't contain the entire PK, which causes this:

[hibernatetool] An exception occurred while running exporter #2:hbm2java (Generates a set of .java files)
[hibernatetool] To get the full stack trace run ant with -verbose
[hibernatetool] org.hibernate.MappingException: Foreign key (FKD0F44C3AEAE30A85:ACCOUNT_SALES [AccountNumber])) must have same number of columns as the referenced primary key (ACCOUNT_MASTER [MarketId,AccountNumber])

I know this isn't really hibernate's fault, though... I think it's just that the person designing our schema is a nutcase. :)

Is there a way to turn off the attempts at foreign key mapping for these two tables? I tried throwing this at the reveng.xml file, 'cuz I *think* this is what the documentation says I should do:

<table name="ACCOUNT_SALES">
<foreign-key constraint-name="FKD0F44C3AEAE30A85:ACCOUNT_SALES">
<many-to-one property="accountMaster" exclude="true"/>
</foreign-key>
</table>

<table name="ACCOUNT_MASTER">
<foreign-key constraint-name="FKD0F44C3AEAE30A85:ACCOUNT_SALES">
<set property="accountSaleses" exclude="true"/>
</foreign-key>
</table>

but it doesn't seem to affect the output to either AccountMaster.hbm.xml or AccountSales.hbm.xml ... AccountMaster.hbm.xml still contains:

<set name="accountSaleses" inverse="true">
<key>
<column name="AccountNumber" not-null="true" unique="true" />
</key>
<one-to-many class="AccountSales" />
</set>

and AccountSales.hbm.xml still contains:

<many-to-one name="accountMaster" class="AccountMaster" update="false" insert="false" fetch="select">
<column name="AccountNumber" not-null="true" unique="true" />
</many-to-one>

I'm assuming that I haven't defined the table overrides in my reveng.xml file correctly??

Thanks for all of your help... I know it's dififcult to diagnose other people's stuff. Frankly, I'm amazed that you were able to see my mistake earlier so quickly! :)

I was using the made-up name for the FK constraint instead of Sybase's "real" schema metadata name. Changed it to this and all is hunkey dorey...

<table name="ACCOUNT_SALES">
<foreign-key constraint-name="FK_ACCOUNT_SALES_AccountNumber">
<many-to-one property="accountMaster" exclude="true"/>
</foreign-key>
</table>

<table name="ACCOUNT_MASTER">
<foreign-key constraint-name="FK_ACCOUNT_SALES_AccountNumber">
<set property="accountSaleses" exclude="true"/>
</foreign-key>
</table>

Thanks again for all you help!!!

glad you solved your problem.

Could you post a minimal(?) schema that shows your "nutcase situation" ? We should at least be able to read it into the model instead of failing on it.

Actually, I searched through JIRA, and it seems that the issue to which I'm referring has already been mentioned in HBX-620 (http://opensource.atlassian.com/project ... se/HBX-620). Our situation looks like this, but I think it's virtually identical to the issue that was raised already:



IMHO, I think it's generally a bad idea to setup situations like this, where the FK on ACCOUNT_SALES refers to part of a compound PK on ACCOUNT_MASTER, which is why I called it a "nutcase" situation. Perhaps it oughtta work anyway, but I wouldn't make it a top priority 'cuz the schema is so ugly. ;)

i'm not planning on supporting it, just want to make it not fail ;)

put a link on the jira then we can keep this forum and that bug connected.

In a previous post in this forum, "mdesjardins" notes that he switched his jdbcconfiguration back to a plain configuration in his ant build. It's also noted in a earlier post that, to use customized hbm templates, we have to separate the hibernatetools taskdef into 2 separate steps - one for hbm2hbmxml, and a second for hbm2java that USES the output hbm.xml files of the first.

It still took me hours to get this to work due to a couple of "missing-links" in the descriptions. Hope this message helps others get over the hump.

Here is a working ant file that brings the output of hbm2hbmxml into the input of hbm2java. This shows one way to do it. Of course, there is probably a better way, and I'd love to hear it!



Since the switch from velocity to freemarker, some of the old template customization comments in the forum are out of date. To get a meta tag for "toString" into your hbm.xml and thus into your java, you need to extract freemarker template files from the hibernatetools.jar file, modify them, and place them in a sub-folder in your project with the same folder name as the original, i.e., hbm, pojo, etc. You also have to add templatepath to your hbm2java task (pointing to the template folder that holds the pojo folder). See example above.

I added meta toString and equals lines to freemarker templates "pojo/pkcolumn.hbm.ftl" and "pojo/property.hbm.ftl". These may not be perfect (pk used in equals currently), but they're a start.

Here is the modified "pkproperty.hbm.ftl"



Here is the modified "pkcolumn.hbm.ftl"

You do know that applying toequals on every property is *bad* ?

I would love to hear what those "missing links" in the docs are and possible remedies for them :)

The missing links are more to do with people's emails here, rather than the documentation - specifically mdesjardins saying to split build into 2 steps, one taking the input of the other, but not showing how to do that. My post shows how to do that, though probably not the best way, at least it works! The other being which freemarker templates need to be modified and how for toString and equals.

I noted in my post "These may not be perfect (pk used in equals currently)" - so, yeah, id in equals is bad if detached objects accessed used outside a session before an id is assigned. Don't have that situation in our app, but probably should avoid the possibility anyway. I read the all the previous emails in this topic several times (still didn't follow them!).

Overall, after about a week, I'm finally getting the generation to work pretty much as it had been working in Middlegen on about 20 tables - planning to do more as I go. Two differences between middlegen and hibernatetools that will require code changes in client code are:

1) the name of a composite key class is tableNameId instead of tableNamePK from middlegen.

2) the method to get a composite id is getTableNameId instead of getComp_id from middlegen.

Thanks!

I need to use jdbcconfiguration since I specify the additional properties (packagename, revengfile, and detectmanytomany). The issue is that the moment you specify the fileset of hbm.xml files (I need to add custom code to certain classes) containing meta attributes, the org.hibernate.cfg.JDBCBinderException exception appears with the following stack trace.

I am using HSQL. Not sure if it matters which DB it is.

Is this an issue with jdbcconfiguration? I am using hibernate tools 3.2.4.GA from ant.

O problema ocorre quando existem dois nomes de fk iguais em tabelas do mesmo schema - basta alterar o nome de uma fk que está repetida e o problema está solucionado.
