Trying to reverse engineer a legacy database with minimal configuration.

Here is the reveng file:

Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering SYSTEM
  "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd">

<hibernate-reverse-engineering>
  <table-filter match-name="ts_.*"/>
</hibernate-reverse-engineering>


The error and stack trace are as follows:

[hibernatetool] 2007-05-23 15:47:19,341 ERROR [freemarker.runtime] - <>

Being unfamiliar with Hibernate Tools and Freemarker, I can't make any sense of this error. If I left out any information that would be helpful please let me know and I'll post it.

somehow the reverse engineering resulted in not having an id defined for an entity (which is broken).

could you show which tables it is generating for ? if more than 2 then please reduce it to that ;)

There are actually about 40 tables in the database. The mapping files are generated for three of them but they don't seem to be going in any particular order that I can discern. Is there a quick way of determining the table that is causing the error (I don't see it anywhere in the output) or will I just have to go through all of them one at a time?

enable debug log (put a log4j.properties in classpath)...should tell you what it is about to do.

So the table in question has a composite key which is my best guess as to why it's breaking.

+--------------------+---------+------+-----+------------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------------------+---------+------+-----+------------+-------+
| id_test | int(11) | | PRI | 0 | |
| id_experiment_type | int(11) | | | 0 | |
| start | int(11) | | PRI | 0 | |
| end | int(11) | | | 0 | |
| mod_date | date | | PRI | 0000-00-00 | |
+--------------------+---------+------+-----+------------+---------+

Any suggestions?

(Sorry, this looks a lot better in the editor than it does in HTML)

what version are you using ? id.hbm.ftl should handle any kind of id combination.
