JNDI Setup Issues

[remmeier]

I'm generating DDL scripts with Hibernate 5.1. No database connection is necessary. But it still attempts to connect to the jta-data-source definied in the persistence.xml (org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name...):

java:comp/DefaultDataSource

I expected this to work after setting vendor = 'hibernate' and adding the package-scan (using the xml-less branch of the plugin logic). Hibernate still seems to use the persistence.xml.

Maybe a custom classloader would allow a more flexible handling of persitence.xml files should Hibernate itself does not allow it.

created an issue on the Hibernate site as well: https://hibernate.atlassian.net/browse/HHH-10783

Sorry for too late response...

You cannot use JNDI for create schema, cause schema generator does not run on servlet instance.
Instead, you can emulate database (see document) or use direct database connection for really need connection.

Thanks.
