Re: [dspace-tech] DSpace 7.3 - create-administrator error

[Tim Donohue]

Hi Jan,

That error appears to be saying you have a database connection issue.  I'd recommend checking your dspace.log file for more details... it's highly likely you have errors in that log file related to the database connection.  It's unclear what the exact problem may be though, so you'd need to check the dspace.log file.

Subject: [dspace-tech] DSpace 7.3 - create-administrator error

 

Hi,

we are testing DSpace 7.3 and the installation fails with the installation of backend.

This we get from the build as warning:

 2022-07-04 12:56:15,162 WARN  org.dspace.servicemanager.DSpaceServiceManager @ Unable to locate bean by name or id=database. Will try to look up bean by type next.

and when running create-administrator command, it fails with:

Exception: null

java.lang.NullPointerException

    at org.dspace.core.AbstractHibernateDAO.getHibernateSession(AbstractHibernateDAO.java:59)

    at org.dspace.core.AbstractHibernateDAO.createQuery(AbstractHibernateDAO.java:137)

When trying the same installation scrips with 7.2.1, it works fine.

Thank you for any help

Jan

Hi both,

If it works in DSpace 7.2.1, but not 7.3, it could be due to the database dialect issue. DSpace 7.3 uses a newer Hibernate, which changes the supported dialects. Make sure your local.cfg and dspace.cfg are using:

db.dialect = org.hibernate.dialect.PostgreSQL94Dialect

Previously the dialect was DSpacePostgreSQL82Dialect. This one bit me and I was confused for weeks until someone mentioned it recently on the DSpace Slack.

Hopefully that helps,
