[Persistence] - Re: how to create PersistenceUnit and map to dataSource prog

by javatwo

Thanks for help. If one peristence unit is mapped to many data sources(with same tables), is there any problems with Hibernate caching? We tried the following in a stateless session bean: Map configOverrides = new HashMap(); EntityManagerFacotry emf = Persistence.createEntityManagerFactory("unit1", configOverrides); But got exception: javax.persistence.PersistenceException: [PersistenceUnit: unit1] Unable to build EntityManagerFactory <persistence-unit name="unit1"> | <jta-data-source>java:/dataSource1</jta-data-source> | | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> | <property name="hibernate.hbm2ddl.auto" value="update"/> | <property name="hibernate.show_sql" value="false"/> | </properties> | </persistence-unit> But the following works. @PersistenceContext (unitName="unit1") | protected EntityManager em; What is the right way to create entityManagerFactory? Thanks!

[Installation, Configuration & Deployment] - Re: How to create a new profile outside theJboss-as/server d

by jdabbi

Jboss comes with a set of ptofiles such as default, all, web, etc. they are in the jboss-as/servers directory. I would like to create a new profile for each node of my cluster. however, i would like to place this profile on a separate drive and directory that is outside the jboss-as directory tree. Thanks for your help in advance.

by jaikiran

Is that the complete stacktrace? It isn't completely informative. bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/pcas-data.xml]: Invo | cation of init method failed; nested exception is java.lang.reflect.UndeclaredThrowableException | at org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray(ConstructorRes | olver.java:698) | at org.springframework.beans.factory.support.ConstructorResolver.autowireConstructor(ConstructorRes | olver.java:192) | Although this piece doesn't say much, it seems to be coming from the spring framework classes. If there's more in the stacktrace, do post that part.

by jaikiran

By "profiles" do you mean, you want to place the deployments outside the JBoss AS folder structure? Or do you want to complete create a new set of profile which includes the "lib", "deployers" etc...?

BTW, the whole deployment is in an EAR, the class EJBProvider (see above) is in a web module, and the referenced EJB of course in an EJB module.

[JBoss Microcontainer Users] - Re: How to get DeploymentUnit?

by Juergen.Zimmermann

I've to implement a class as follows: | import java.lang.reflect.Type; | import javax.ejb.EJB; | import javax.naming.Context; | import javax.naming.InitialContext; | import javax.naming.NamingException; | import javax.ws.rs.ext.Provider; | import com.sun.jersey.core.spi.component.ComponentContext; | import com.sun.jersey.spi.inject.Injectable; | import com.sun.jersey.spi.inject.InjectableProvider; | | @Provider | public class EJBProvider implements InjectableProvider<EJB, Type> { | public Injectable<Object> getInjectable(ComponentContext componentCtx, | EJB ejbAnnotation, | Type type) { | if (!(type instanceof Class<?>)) | return null; | | Class<?> clazz = (Class<?>) type; | | String beanInterface = ejbAnnotation.beanInterface().getName(); | if (Object.class.getName().equals(beanInterface)) { | beanInterface = clazz.getName(); | } | | String jndiName = ???; // get jndi name via beanInterface | | Context ctx = null; | try { | ctx = new InitialContext(); | Object obj = ctx.lookup(jndiName); | | return new Injectable<Object>() { | public Object getValue() { | return obj; | } | }; | } | catch (NamingException e) { /* error handling */ } | finally { /* close ctx */ } | } | } So my 1st problem is: how to get the jndi name when the interface of an EJB is available? I was trying the following where I only would need the DeploymentUnit object. Perhaps there are alternatives. Any hint is highly appreciated! //import org.jboss.deployers.structure.spi.DeploymentUnit; | //import org.jboss.ejb3.common.resolvers.plugins.FirstMatchEjbReferenceResolver; | //import org.jboss.ejb3.common.resolvers.spi.EjbReference; | //import org.jboss.ejb3.common.resolvers.spi.EjbReferenceResolver; | | EjbReference ref = new EjbReference(ejbAnnotation.beanName(), | beanInterface, | ejbAnnotation.mappedName()); | EjbReferenceResolver resolver = new FirstMatchEjbReferenceResolver(); | | DeploymentUnit du = ???; // How to get DeploymentUnit? Via ClassLoader? | | String jndiName = resolver.resolveEjb(du, ref); | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4266911#4266911 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4266911
