[jboss-user] [JBoss Microcontainer Users] - Re: How to get DeploymentUnit?
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 InjectableProviderEJB, Type {
| public InjectableObject 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 InjectableObject() {
| 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);
|

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.

Dunno, this is EJB question not MC. ;-)
Either ask on their forum or check Weld-int
where, afair, something similar had to be implemented.

This way you get the deployment unit owning the classloader/module,
but to actually get the right deployment unit you would need to check the whole
hierarchy of this unit.
e.g.
get class's source location, and check it against unit's and sub-units
classpath roots.

Actually that's not correct (hence my off the top of my head), as Module/ClassLoader can be created from different/multiple (sub)deployments. e.g. ear + jars Why exactly do you need DeploymentUnit? What is your environment - where do you want to access DU from? Looks like class's classloader is your starting point. Why? Give more details and we'll find the solution together.
