Urgent help: roo & Sybase Anywhere 11

[dule]

My RDBMS is up and running on port 1234.

After setting topLevelPackage, I've entered the following:

persistence setup --provider HIBERNATE --database SYBASE --userName sa --password sa
database properties set --key database.url --value jdbc:sybase:Tds:127.0.0.1:1234

after that, database.properties content is:

#Updated at Fri Nov 26 14:53:54 CET 2010
#Fri Nov 26 14:53:54 CET 2010
database.password=sa
database.url=jdbc\:sybase\:Tds\:127.0.0.1\:1234
database.username=sa
database.driverClassName=net.sourceforge.jtds.jdbc.Driver

Everything looks OK, but command
database introspect --schema sa
just returns error message:

Connection must not be null

and nothing more! I can't make roo to work with Sybase Anywhere, any help?

After installing 1.1.0.RELEASE, now after database introspect --schema schemaName, I'm getting the following error:

No remote OBR repositories have matching add-ons matching your request
JDBC driver not available for 'net.sourceforge.jtds.jdbc.Driver'

After

script --file install-jdbc-drivers.roo

I'm getting the error as described in the first post.

Maybe open source driver doesn't work well with Sybase Anywhere 11?

@roo developers

Accordingly to jtds.sourceforge.net/faq database url genereated by roo is invalid, it should be:
jdbc:jtds:<server_type>://<server>[:<port>]

With a valid url there is no error "Connection must not be null" anymore, but now I have another problem... I'm always getting error message that DB scheme not exists or is empty (which is not the case). I've tried various combinations for --scheme parameter, but without success.

Any help??
