First time using the eclipse tools - installed the plugins, but when i used the wizard to create a console configuration, i got this error:

error messages:
Error 2005-12-05 13:51:22.562 ERROR Worker-13 org.hibernate.util.NamingHelper - Could not obtain initial context
javax.naming.NoInitialContextException: Cannot instantiate class: org.apache.naming.java.javaURLContextFactory [Root exception is java.lang.ClassNotFoundException: org.apache.naming.java.javaURLContextFactory]
at javax.naming.spi.NamingManager.getInitialContext

I found that class (in naming-factory.jar) & added the jar to the wizard's dialog-box list for "classpath" (along with my jdbc driver jar), but i'm still getting the error. Do i need to add the jar elsewhere? I didnt find anything in docs (or forums) about this.

Hibernate version:3.1rc3, tools 3.1.0.beta1; eclipse 3.1.0
Name and version of the database you are using:DB2/400 (AS400)
(i'm hoping to rev-eng an AS400 db...)

there are no datasources in eclipse so you will need to use pocs (plain old connection settings ;)

i don't understand how that relates to the classNotFoundException.

Here's my config file, if that makes a difference. It was created using the wizard:
<hibernate-configuration>
<session-factory name="SessionAS400test">
<property name="hibernate.cglib.use_reflection_optimizer">true</property>
<property name="hibernate.connection.driver_class">com.ibm.as400.access.AS400JDBCDriver</property>
<property name="hibernate.connection.password">pw</property>
<property name="hibernate.connection.url">jdbc:as400://192.100.100.1</property>
<property name="hibernate.connection.username">name</property>
<property name="hibernate.default_schema">bwhtst</property>
<property name="hibernate.dialect">org.hibernate.dialect.DB2400Dialect</property>
</session-factory>
</hibernate-configuration>

and you have no hibernate.properties ?

try and remove the session factory name - it should just work.

problem solved - bad schema name

Last night I set up an ANT script to do the rev-eng & I eventually got that working. Problem was in the cfg - default_schema had to be uppercase (BWHTST, not bwhtst). When I saw your post I went back & tried it in eclipse, & it works there, too, now. So when the schema name doesn't match, it gets the ClassNotFoundException. Running in the ANT script, there's no error, you just don't get any tables processed.

It would be nice in either situation to get a warning/error message instead of (a) Exception or (b) no output.
