Hi community,
I've got a standard java command line application and I'd like to use hibernate to realize the persistence layer. I need to create mapping files first and then the POJOs. I decided to use the HibernateTools for this task.

I followed the HibernateTools reference documentation (http://www.hibernate.org/hib_docs/tools/reference/en/html/) and all worked fine. I created a Hibernate configuration file, a Hibernate Console configuration, set the Code Generation Launcher and edited my reveng.xml to set the general type mappings.
I hope that all of the important Hibernate libraries were placed into my lib directory and set up in "Java Build Path".
I was finally back at the point of "Exporters" (http://www.hibernate.org/hib_docs/tools/reference/en/html/plugins.html#d0e371) to run the code generation after having read the following chapters as well. Unfortunately nothing happend.

The database connection set in hibernate.cfg.xml is working because the database tree is shown in the hibernate configuration view. The type mappings could be set as well and they also need DB connection to show the columns' types.

Thanks in advance!

did you point to a database which actually had tables ?
did your schema/catalog setting match ?
what is in your cfg.xml and reveng.xml ?

Yes, I did. The database pointed to contains tables. They are, for instance, visible in "Hibernate Console Perspective"-->"Hibernate Configurations" view-->"Database".

The following code should take alle tables from my schema:

Code:

<table-filter match-schema="mySchema" match-name=".*"/>

hibernate.cfg.xml:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

hibernate.reveng.xml:

Hi, it's still not working.

By the way, opening the Hibernate configuration tree in the Hibernate Console perspective lets appear a warning in the error log:

Code:

Warning 2006-04-17 14:42:32.135 WARN Worker-0 net.sf.ehcache.config.Configurator - No configuration found. Configuring ehcache from ehcache-failsafe.xml found in the classpath: bundleresource://153/ehcache-failsafe.xml

The number behind "Worker-" changes.
Can this have something in common with my problem?

if you don't get any errors then your console configuration does not contain anything.

And are you sure "mySchema" is the correct case for the schema ?

Try and just remove that from hibernate.reveng.xml.

the warning is just a warning from ehcache. normal.

Unbelievable, you're right!

Removing

Code:

<table-filter match-schema="mySchema" match-name=".*"/>

caused that all mapping files and POJOs were created.
It seems to be wrong to choose my database in the table filters tab of my hibernate.reveng.xml... Now, working, the database appears as catalog attribute of the class element in my mapping files. Weird.

Nevertheless, many thanks!

probably because mysql is case sensitive here
