            JPA: How to specify tables from different DB2 schemas using @NamedQuery. Schema.Table cannot be the first declaration of the FROM clause
            Asked 2021-Nov-02 at 00:37

            I encountering a problem when sending a GET request from Postman to test my endpoints. The same NamedQueries worked before with Derby with just the one Schema, so no need to differentiate then. I have now changed to DB2 running in a local Docker instance and am using Maven to run Open-Liberty Framework to create the endpoints. I am receiving the below error. Do I need to create a orm.xml file with entity-mappings, or do something else to resolve this? I would prefer to do this without more xml files if possible.

            How to specify tables from different DB2 schemas using @NamedQuery

            AFAIK, you cannot configure the schema value at the query level. All the named queries defined under the Entity at expected to be executed against the same schema.

            1. The database schema can be set at the persistence-unit level via orm.xml mapping file:




            Entity Manager is null when trying to connect to Dockerised DB2 in Java using JPA, also using maven & Open Liberty
            Asked 2021-Oct-29 at 08:33

            So I'm developing an API and I'm trying to connect to a local docker instance of DB2 from java using JPA entity manager. After running Apache Maven and getting build success, I try a GET request from Postman to test an endpoint and get a list of all users from DB2. I'm receiving the below error saying that entity manager is null. I've tried researching online and can't seem to find the solution. The Dao class is virtually unchanged from a previous iteration that used Derby instead of DB2 and it worked fine. I was wanting to know where I've gone wrong, what needs changing, and if anything is not needed. Provided below is the xml files and the DAO java class containing the entity manager. All properties for DB2 is correct as they're unchanged from a successful connection I was able to do from Eclipse's Database Development. The driver used then was db2jcc4 which I think is different to the driver said to use for the maven dependency so not sure if that's an issue.

            Your persistence.xml is incorrect. It should point to datasource configured in the server.xml, not specify driver properties.

            It looks like you followed the example here:

            Based on the exception, it looks like the driver jar isn't in the jdbc directory (which will be wlp/usr/server/server_name/jdbc) You should be able to get the version you need here:

            If you're using maven, you can use the Liberty Maven Plugin to download and copy the driver to the correct directory for you. Here's an example using the latest 8.0.26 driver:

            My persistence.xml is inside META-INF folder

            CategoriesMicroservice-1.0.war/META-INF/ ?

            JPA Spec; section 8.2:

            A persistence unit is defined by a persistence.xml file. The jar file or directory whose META-INF directory contains the persistence.xml file is termed the root of the persistence unit. In Java EE environments, the root of a persistence unit must be one of the following:

            • an EJB-JAR file
            • the WEB-INF/classes directory of a WAR file[87]
            • a jar file in the WEB-INF/lib directory of a WAR file
            • a jar file in the EAR library directory
            • an application client jar file

            If the persistence.xml was packaged incorrectly though, you should be getting exceptions concerning missing persistence-unit references to jpa-unit.

            Dependency plugin 'outputDirectory' must match server.xml directory

            You need to align your server config with the location you copy the dependency to in your Maven build.

            (Your problem seems to be you have an extra 'jdbc' subdir in your server config, compared to the location you're copying into from your Maven build).
