Thank you.

FTR this is my current setup:


root pom.xml:

      <dependency>
        <groupId>org.apache.openjpa</groupId>
        <artifactId>openjpa</artifactId>
        <version>${openjpa.version}</version>

core/persistence-jpa/pom.xml:

    <dependency>
      <groupId>jakarta.persistence</groupId>
      <artifactId>jakarta.persistence-api</artifactId>
    </dependency>
    <dependency>

I am having issues now with entity enhancement.

I see log messages like as

[BuilderThread 0] openjpa.Tool - Enhancer running on type "class 
org.apache.syncope.core.persistence.jpa.entity.group.JPAGPlainAttr".

but afterwards:

[BuilderThread 0] openjpa.Tool - No metadata was found for 134 classes; they 
have been enhanced as persistence-aware. If you intended for any of these 
classes to be persistence-capable, then this means that OpenJPA could not find 
any metadata for those classes.

I guess this is because of the namespace mismatch between openjpa-maven-plugin 
and the openjpa dependency as declared above.

Regards.

Yes, think you should either move to openjpa-all shade or generate the
class with asm at build time (guess switching the main dep is easier).

Unfortunately just switching to openjpa-all does not change the errors I
am reporting below.

When I look inside


https://repo1.maven.org/maven2/org/apache/openjpa/openjpa-all/3.2.2/openjpa-all-3.2.2.jar

what should I be able to see exactly? e.g. what would be the effect of the
relocation settings in

https://github.com/apache/openjpa/blob/master/openjpa/pom.xml#L100

?

In case this option is not viable: would you be able to suggest how to
proceed with asm-based alternative you are mentioning above?
TIA.

Regards.

Hi,

Well I guess the jakarta shade should handle jakarta properly else

user

can

use what he wants and finally worse case you can still integrate the
mapping in spring glue code (not sure you have something particular in

mind

so shouting in the wind ;)).

For instance, I would like to keep these classes [1] working, but when

attempt to build it, I am receiving the following errors:

Given Maxim's and yours answer about openjpa-all, I believe I'll need

to

either depend on that or shade OpenJPA artifacts right on Syncope poms:
correct?

Hi all,
so let's suppone one has the weird idea of adding OpenJPA to a Spring

Boot

3 project.

Do we already an idea about how to handle the javax.persistence.*  Vs
jakarta.persistence.* conflicts?

Thanks in advance.
Regards.
