hi,
I have a problem with jpa on servicemix
when my bundle starts, I created a route builder.
In the constructor of the class, I ask a database to know the route definition to create.
it is only at this point that I know the name of the datasource to use (already declared in osgi).
I have to define jpa consumer who will use this base.
But in the documentation and examples, the percistence JPA is defined in an XML file on bundle META-INF.
I do'nt know how to tell jpa to use the datasource name that I have only on creation of the route builder.
Can I leave the persistence.xml file in the bundle and change the name of the datasource in the road builder?
or should I create a persistenceUnit on the road builder?
and in both cases, how?
I have it in my persistence.xml file:
<jta-data-source>osgi:services/javax.sql.DataSource/(name=aDataSource)</jta-data-source>
but I do not know what name is given to the datasource when starting the bundle
A+JYT
public class MyRouteBuilder extends RouteBuilder {
private String final MY_MODULE_NAME="logistique.livraison";
protected ModuleConfig moduleConfig = null;
public MyRouteBuilder() {
super();
//GetConfiguration from extenal config servivce
moduleConfig = ConfigHelpper.getConfig(MY_BUNDLE_NAME);
logger.log(moduleConfig.getInDatasource());
}
public void configureRoute() throws ExceptionOlympe {
//how to use the value of moduleConfig.getInDatasource() in
// jpa://my.domain.model.Livraison?consumer.delay=2000
from("jpa://my.domain.model.Livraison?consumer.delay=2000")
.bean(...)
...
;
