Hi,
i have some problems generating my databade DDL script from hibernate mapping files.

Here are the steps i had followed :

1- unzip hibernate release 3.2 in the folder
c:\hibernate-3.2

2- set hibernate.properties parameters
here is its content:
hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
hibernate.connection.driver_class=org.postgresql.Driver
hibernate.connection.url=jdbc:postgresql:localhost:5432:ma_bd
hibernate.connection.username=mon_login
hibernate.connection.password=mon_pwd

3- add the environment variable CLASSPATH
with hibernate jar path and PostgresSQL 8.0

4- my mapping files
are located in the folderc:\hibernate-3.2\mon_mapping
(this folder contains several mapping files)

5-on command line, i typed the command :
c:\hinernate-3.2>java org.hibernate.tool.hbm2ddl.SchematExport --text --format --properties=etc\hibernate.properties --output=ma_ddl.txt etc/mon_mapping/*.hbm.xml

6 - then got the error message:
Exception in thread "main" Java.lang.noClassDefFoundError : org/hibernate/tool/hbm2ddl/SchemaExport

thanks for your help

some jar files where missing in my CLASSPATH
this is ts content :
C:\hibernate-3.2\hibernate3.jar;c:\hibernate-3.2\lib\commons-logging-1.0.4.jar;c:\hibernate-3.2\lib\ehcache-1.2.3.jar;c:\hibernate-3.2\lib\cglib-2.1.3.jar;c:\hibernate-3.2\lib\jta.jar;c:\hibernate-3.2\lib\asm.jar;c:\hibernate-3.2\lib\antlr-2.7.6.jar;c:\hibernate-3.2\lib\jaxen-1.1-beta-7.jar;c:\program files\postgresql\8.0\jdbc\postgresql-8.0-310.jdbc3.jar;c:\hibernate-3.2\lib\commons-collections-2.1.1.jar;c:\hibernate-3.2\lib\dom4j-1.6.1.jar;c:\hibernate-3.2\lib\log4j-1.4.11.jar;c:\hibernate-3.2\lib\asm-attrs.jar

It works now!

Check CLASSPATH always
