Hi Armin. I imagined that I wasn't doing it properly. Until now it looks going well, but I don't like it. I hope to test it properly very soon and I'll tell you. What I should do is to have 2 ojb.properties and 2 database-repository.xml. I tried to do so, putting one in the ejbs directory, and one in web-inf/classes. But daos that aren't called by ejbs too look in the files of property in ejbs.
I have this structure Ejbs/(ojb.properties, repository.....) Ejbs/com/brujulatelecom/srv/ejb/myejb Ejbs/com/brujulatelecom/srv/dao/SalidaDAO Then Web/WEB-INF/classes/ com/brujulatelecom/srv/dao/SalidaDAO Web/WEB-INF/classes/(ojb.properties, repository.....) I want to use the same SalidaDAO in both cases. But I don't obtain /brujulatelecom/srv/dao/SalidaDAO looking in Web/WEB-INF/classes/(ojb.properties I know it should be just a problem of configuration, and I hope study and solve it very soon Thanks -----Mensaje original----- De: Armin Waibel [mailto:[EMAIL PROTECTED] Enviado el: martes, 05 de octubre de 2004 0:48 Para: OJB Users List Asunto: Re: Ejb calling DAO Hi, > I would like to note one think. > Documentation says to use PersistenceBrokerFactorySyncImpl just in > managed environment. > My environment is managed (OC4J) but I use many daos normally without > ejb, and all seem go well with PersistenceBrokerFactorySyncImpl too. A managed environment != ejb it describes an environment with services like JAAS, JNDI, JTA, ... (maybe I'm wrong ;-)) In managed environments the tx handling is done by JTA and PersistenceBrokerFactorySyncImpl interact with JTA-TxManager. You can use OJB without ejb (read operations shouldn't cause problems), but it is not allowed to use the PB-tx demarcation in managed environments. In this case you have to use JTA-UserTransaction. The exception proves the rule. If you define an DataSource with connections which will not be automatic managed by JTA. In this case the connections independent from JTA and behave like "normal" connections (but this couldn't be handled by PersistenceBrokerFactorySyncImpl). regards, Armin Alessandro Colantoni wrote: > Hi and good Monday. > At the end i done it as you suggest. > > I've just dune an other contructor for my dao in this way > private PersistenceBroker extBroker = null; > > /** > * > * @param extBroker > */ > public SalidaReservaDAO(PersistenceBroker extBroker){ > this.extBroker=extBroker; > } > > public SalidaReservaDAO(){ > } > > then in myMethod of the dao I put > > > try { > if (extBroker!=null){ > extBroker.store((SalidaReservaVO)salidaReservaVO); > }else{ > broker = ServiceLocator.getInstance().findBroker(); > broker.beginTransaction(); > broker.store((SalidaReservaVO)salidaReservaVO); > broker.commitTransaction(); > } > } catch (ServiceLocatorException e) { > broker.abortTransaction(); > log.error("PersistenceBrokerException thrown in > SalidaReservaDAO.store(ValueObject salidaReservaVO): " + e.toString()); > throw new DataAccessException("Error in > SalidaReservaDAO.store(ValueObject salidaReservaVO): " + > e.toString(),e); > } finally { > if (broker != null) broker.close(); > } > > In this way I can use Mydao in other part of the application that don't > use ejb. > > Thanks a lot for your help. > > I would like to note one think. > Documentation says to use PersistenceBrokerFactorySyncImpl just in > managed environment. > My environment is managed (OC4J) but I use many daos normally without > ejb, and all seem go well with PersistenceBrokerFactorySyncImpl too. > > -----Mensaje original----- > De: Alessandro Colantoni [mailto:[EMAIL PROTECTED] > Enviado el: sábado, 02 de octubre de 2004 16:25 > Para: 'OJB Users List' > Asunto: RE: Ejb calling DAO > > Hi. > > I put > name="srvOracleDS" > location="srvOracleDS" > xa-location="srvOracleXADS" in datasource.xml > and > jndi-datasource-name="srvOracleDS" in repository-database.xml > > It looks like going well. > Thanks very much. > > When you talk about myMethod() I suppose you refer to a method of the > ejb. > I would like to open the broker in the Dao. > > I'm trying doing something like that: > > public void ejbCreate() { > > > } > > public myEjbMethod(){ > > call dao1.methodh_a() > call dao2.methodh_b() > call dao3.methodh_c() > > if something wrong rollback all dao operations > > } > > And in Daox > > public method_a(){ > > InitialContext context = null; > try { > context = new InitialContext(); > OjbPbFactory factory= > (OjbPbFactory)context.lookup("PBFactory"); > } > OjbPbFactory factory= > (OjbPbFactory)context.lookup("PBFactory"); > > PersistenceBroker broker = factory.getInstance()..... > try > { > // do work here > ..... > }finally > { > if(broker != null) broker.close(); > } > } > > what do you think about? > > > > -----Mensaje original----- > De: Armin Waibel [mailto:[EMAIL PROTECTED] > Enviado el: sábado, 02 de octubre de 2004 15:59 > Para: OJB Users List > Asunto: Re: Ejb calling DAO > > Hi again, > > I would advice to use 'jdbc/srvOracleCoreDS' as jndi-datasource-name in > OJB - long shot ;-) > Does this cause same error? > > [off-topic] > Further on in ejbCreate() in your bean I would only lookup the > OjbPbFactory instance and keep it as inst var in bean.
