Please help,

I have problems generating code under Middlegen-Hibernate-r4
with path not found, and nothing is generated.

was not configured to look for tables in a specific schema. You should consider specifying schema="null" in the middlegen task.

I don't use mySQL but there have been others with this problem on the forum. Two (possible) solutions:
1) Provide the schema name
2) Include the extra mySQL JAR that comes with the full Middlegen package.

I might just include that JAR with the next release (r5) comes out.

the GUI can get all relations and tables.
I've changed the mysql jar for mysql-connector-java-3.0.0-beta-bin.jar

but it is still the same problem:
path not found

it creates one empty file in
build\gen-src\airline\hibernate\Reservation.hbm.xml

I don't know what to do to resolve it

I've tried also
mysql-connector-java-2.0.14-bin.jar
mysql-connector-java-3.0.10-stable.zip

I've the same problem with middlegen-2.0-vo version
The GUI detects all 3 tables and relations but exception is thrown:

the problem was in the path, since it contained the '!' sign.
I've moved it away and it worked great.
