Error 90048: Unsupported database file version or invalid file header

[Vincent Cattin]

Hi,

I'm using a H2 database (H2 1.2.127) together with eclipse galileo and
hibernate (Hibernate Tools 3.2.4). When I try to launch a hibernate
code generation from the database on eclipse, I get the following
error (actual filename has been replaced by tag <filename>):

org.hibernate.exception.GenericJDBCException: Getting database
metadata
Getting database metadata
org.h2.jdbc.JdbcSQLException: Unsupported database file version or
invalid file header in file <filename> [90048-120]
Unsupported database file version or invalid file header in file
<filename> [90048-120]
org.h2.jdbc.JdbcSQLException: Unsupported database file version or
invalid file header in file <filename>[90048-120]
Unsupported database file version or invalid file header in file
<filename> [90048-120]

FYI, here is my hibernate.cfg.xml (actual database filename also
replaced by <filename>):

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property
name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property
name="hibernate.connection.driver_class">org.h2.Driver</property>
<property name="hibernate.connection.url">jdbc:h2:<filename></
property>
<property name="hibernate.connection.username">sa</property>
<property
name="hibernate.dialect">org.hibernate.dialect.H2Dialect</property>
</session-factory>
</hibernate-configuration>

I do not understand why there is a problem with the database file,
because everything works fine when I open it from the H2 Console.

Does anyone have any ideas of what could cause this error?

Thanks in advance,
Vincent

Most likely the problem is that you created the database with version
1.2.127, but Hibernate is still using version 1.2.120. H2 encodes the
build number in the exception message. "-120" means the exception is
from version 1.2.120.
