Thanks Scott.
I managed to retreive information from 2 db with EntityManagerFactory
associated correctly with the good database, thanks to jta-data-source
parameter in persistence.xml.
But for updating the database the factory is useless and I need to use a
global injected EntityManager with a global injected UserTransaction
(with the factory the database is not updated)
@Inject @Named(adlresintestunit1) EntityManager m_ejb1;
@Inject @Named(adlresintestunit2) EntityManager m_ejb2;
@Inject UserTransaction m_ut;
The data is correctly inserted in the good database, but despite the
m_ut.commit(), there is an exception at the end of the http request
handling :
[2014-01-10 08:39:38.227] {resin-port-8000-69}
java.lang.IllegalStateException: Resource
UserConnection[ManagedConnectionImpl[jdbc/adlresintest1.d0.0]] was not
closed. Applications must close all resources in a finally block.

Thanks for any help.

Hello
I will soon have more than one mysql server. I want to use one server
for read requests of static data, the other for read/write requests of
dynamic data. It works for sql requests through datasource, but I cannot
find how to do it with ejb manager.
In my resin.xml I have this :
database jndi-name=jdbc/adlresintest
...
/database
ejb-server data-source=jdbc/adlresintest
create-database-schema=false
jndi-name=ejb/
database jndi-name=jdbc/adlresintest2
...
/database
ejb-server data-source=jdbc/adlresintest2
create-database-schema=false
jndi-name=ejb2/
In persistence.xml :
persistence xmlns=http://java.sun.com/xml/ns/persistence; version=1.0
persistence-unit name=adlresintestunit
providerorg.eclipse.persistence.jpa.PersistenceProvider/provider
classadlresintest.Adluser/class
exclude-unlisted-classes /
properties
property name=eclipselink.ddl-generation.output-mode
value=database /
property name=eclipselink.weaving.fetchgroups value=false/
/properties
/persistence-unit
/persistence
In my java code I have this :
@Inject @Named(jdbc/adlresintest) public DataSource
m_datasource1;// public site
@Inject @Named(jdbc/adlresintest2) public DataSource
m_datasource2;// not used for the moment
@PersistenceUnit(name=adlresintestunit) @Named(ejb)
EntityManagerFactory ejbfactory1;
@PersistenceUnit(name=adlresintestunit) @Named(ejb2)
EntityManagerFactory ejbfactory2;
When using datasource1 or 2 I access the correct database. But when
using ejbfactory1 or 2, only the second database is accessed. The
association created with jndi-name and @Named() works for
DataSource/database but not for EntityManagerFactory/ejb-server.
