I've set up my database in TomEE such that it works fine with SQL Query. When
I attempted to do a simple entityManager.find() as a JPA test, I got the
following error:
java.lang.RuntimeException: org.apache.cxf.interceptor.Fault: The bean
encountered a non-application exception; nested exception is:
java.lang.IllegalArgumentException: Unknown entity:
com.example.account.Application
I've gotten around this by adding
<class>com.example.account.Application</class> to my persistence.xml file.
However, in JBoss everything Just Works thanks to annotations and I don't need
to use XML to set up my entities at all. On the one hand it's a bit of a
bummer to add in all that XML but I can handle it if I have to. I'm
experiencing some other issues though so I'm wondering if there's a bigger
configuration problem that I should address.
I've also tried using
<exclude-unlisted-classes>false</exclude-unlisted-classes> and <property
name="hibernate.archive.autodetection" value="class" /> but neither of these
seems to have made a difference for me.
Because of the custom JNDI naming system in my code, and to keep things simple,
I've been slowly adding in files into WEB-INF/classes/com/example. I could
package them into WEB-INF/lib/example.jar but then I think I'd have to rewrite
a LOT of JNDI naming, and my (limited) understanding is that it's not necessary
to package the classes into a JAR for any reason.
Here are some of my other files:
persistence.xml:
<persistence xmlns="http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"; version="1.0">
<persistence-unit name="ExampleEngine">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.example.account.Application</class>
<properties>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hibernate.hbm2ddl.auto" value="update"/>
</properties>
</persistence-unit>
</persistence>
tomee.xml:
<?xml version="1.0" encoding="UTF-8"?>
<tomee>
<Resource id="example_db_prod" type="DataSource">

validationQuery = SELECT 1
JtaManaged true
</Resource>
</tomee>
Thank you very much for any help you can provide. It's a very steep learning
curve trying to do this migration and I keep running into roadblock after
roadblock.
