I agree, 'good need'. Hmmm, but why implement as follows? what is default
value? why the need to 'force'?
configurable through
-Dopenejb.jpa.force.javax.persistence.provider=true|false
I am specifying my datasource(s) in tomee.xml, it references the
jta-data-source name as defined in persistence.xml. I would assume this is
sufficient to specify as many persistence providers in persistence.xml and
as many resources in tomee.xml which reference jta-data-source name's
defined in persistence.xml.
So, my tomee.xml contains the following:
<Resource id="jdbc/mcmsJta" type="javax.sql.DataSource">
JdbcDriver org.apache.derby.jdbc.EmbeddedDriver
JdbcUrl jdbc:derby:C:/javadb/databases/mcmsdev;create=true
UserName ...
Password ...
JtaManaged true
jmxEnabled true
LogSql false
InitialSize 10
MaxActive 100
MaxIdle 30
MaxWait 10000
minIdle 10
suspectTimeout 60
removeAbandoned true
removeAbandonedTimeout 180
timeBetweenEvictionRunsMillis 30000
jdbcInterceptors=StatementCache(max=128)
</Resource>
and persistence.xml contains the following:
<?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

<persistence-unit name="mcmsPU" transaction-type="JTA">
