Apache Tomee 1.5.2: Failed to use JTA (TransactionManager is not found)

Hello, ObjectDB team!

I am struggling with getting ObjectDB 2.5.0 to work with clean Apache Tomee 1.5.2 with transaction-type="JTA". I don't have any configurations in Tomee (objectdb.jar is in Tomee's classpath) nor other parts, excepting the following persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" 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_2_0.xsd">
  <persistence-unit name="N7PU1" transaction-type="JTA">
    <provider>com.objectdb.jpa.Provider</provider>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
      <property name="javax.persistence.jdbc.url" value="$objectdb/n7/db1.odb"/>
    </properties>
  </persistence-unit>
</persistence>

I get the following error at deployment time: Failed to use JTA
If I set transaction-type="resource-local", I can deploy, but not with JTA.

Any hints please? Thanks a lot in advance.

It seems as a resource loading problem. ObjectDB cannot find TomEE's TransactionManager, which is required in order to use JTA.

You may try removing objectdb.jar from TomEE classpath, and putting it in the web application WEB-INF/lib directory.

Try also using objectdb-jee.jar instead of objectdb.jar.

Thanks for such a quick reply. That's one of the main reasons I love ObjectDB.

It seemed that actually I was putting objectdb.jar in the classpath in a wrong way.
Now I use common.loader from catalina.properties and it works properly.

PS. Your solution worked also (with WEB-INF) because I was not loading the jar properly, but WEB-INF was, so it worked. Anyway, not it works by adding objectdb.jar into common.loader from catalina.properties

You are welcome. Thanks for the update.
