I am trying to use JOOQ code generation from JPA Entity. I have already created a dedicated maven module where the code will be generated which has dependency on a module containing all entities as well code generation plugin with of jooq.
To add more clarify on project structure, here are the modules:(The names are made up but the structure reflects the current project i am working on)...

I'm assuming you have missing dependencies on your code generation class path. Once you update your question, I'll update my answer.Regarding jOOQ code generation support for
jOOQ won't support your generated composite types in generated code out of the box, you'll still have to add forced type configurations for that, possibly embeddable type configurations:
Note that the
JPADatabase offers a quick win by integrating with simple JPA defined schemas very quickly. It has its caveats. For best results, I recommend going DDL first (and generate both jOOQ code and JPA model from that), because it will be much easier to put your schema change management under version control, e.g. via Flyway or Liquibase.
I have three tables: event, speaker, event_speaker
Events and speakers have an n:m relationship managed by the "event_speaker" table. I used the jOOQ maven codegen to generate files like "EventRecord" and "SpeakerRecord".
In my application I want to get all speakers for a particular event. So I need to join the "speaker" table with the "event_speaker" table to be able to limit the results by the event id:...

The reason is that
JSON_ARRAYAGG() (like most aggregate functions) produces
NULL for empty sets, instead of a more "reasonable" empty
. Clearly, you never want this behaviour. So, you could use
COALESCE, instead, see also this question:
Can the DefaultRecordMapper handle lists?
Model example (really getter/setter are used):...

The out of the box support for nested collections in jOOQ is via SQL/XML or SQL/JSON, depending on what works best in your SQL dialect. The idea is that you nest collections directly in SQL, serialise the results as XML or JSON, and use JAXB (for XML), or Gson or Jackson (for JSON) behind the scenes to map the document into a hierarchy of Java classes. All of this is quite straightforward and automatic, as soon as you have either JAXB, Gson, or Jackson on your classpath.
An example for your data structures:
I have the following structure in PostgreSQL:...

You can use jOOQ 3.14's SQL/XML or SQL/JSON support for this, see this blog post here
If you have Gson or Jackson on the classpath, they can be used to map the XML or JSON structure back to your Java class hierarchies. An example for that is given on the manual's page about

You can use JOOQ like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the JOOQ component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
