Warm regards to everyone, and thank you very much in advance.

I=E2=80=99m just starting to learn Jakarta EE and Tomee, so I=E2=80=99m not=
 sure if this is
the right
place to ask for help with my problem. But I think it is, because it=E2=80=
=99s
related to Tomee.

I=E2=80=99m learning about Jakarta EE using the tutorial on their website:
Jakarta EE Tutorial
<https://jakarta.ee/learn/docs/jakartaee-tutorial/current/index.html.> I=E2=
=80=99ve
just modified the POMs so that they don=E2=80=99t use GlassFish
 by default, but instead run on the Tomee server I=E2=80=99ve installed loc=
ally;
and change the
persistence.xml to not use eclipse as persistence provider. And, so far,
the examples
have been working correctly.

I am using Tomee 10.0.5 with their default configurations, only and a user
in tomcat-users
to access to the html manager. Then, to test if is the example that is not
working or is Tomee
I installed GlassFish 7 and the example works well. But I want to make it
work with Tomee.

But I got stuck on the example in =E2=80=98Building RESTful Web Services wi=
th
Jakarta REST=E2=80=99
The rsvp Example Application
<https://jakarta.ee/learn/docs/jakartaee-tutorial/current/websvcs/rest/rest=
.html#_the_rsvp_example_application>.
Making some testing I discover that the endpoints of
*ResponseBean.java* works well; and *ConfigBean.java* make their job. But
the problem
comes from executing the endpoints of *StatusBean.java*

However, when trying to debug, I get confusing logs depending on the
configuration.
With the default configuration, the log indicates issues related to
=E2=80=98org.apach.cxf.jaxrs.provider.JAXBElementProvider=E2=80=99.

However, when adding
<property name=3D"openjpa.Log" value=3D"DefaultLevel=3DTRACE, Runtime=3DTRA=
CE,
Tool=3DTRACE"/>
to persistence.xml as the log suggests to obtain more information, the
application fails
to deploy. It throws errors relating to
 =E2=80=98jdk.internal.reflect.NativeMethodAccessorIpml.invoke=E2=80=99.

I have the tutorial code with the changes that i make to work with Tomee in
my github:
https://github.com/Sxtormulo/jakartaee-examples/tree/main/tutorial/jaxrs/rs=
vp
.

These are the errors I get when I try to run the example with and without
the openjpa.Log Trace
property in persistence.xml.

As I=E2=80=99m new to this, I=E2=80=99m not sure if it=E2=80=99s a configur=
ation error, an app
error or a bug.
If it is a bug, I=E2=80=99ll open an issue on GitHub to report it.

Thank you very much in advance for your help.
