Question

Im quite new to all this stuff. I try to launch a webservice via GlassFish. When i try to build this project i get an error.
ant -f /home/philipp/NetBeansProjects/sks3 -DforceRedeploy=false -Ddirectory.deployment.supported=true -Dnb.wait.for.caches=true run

Error occurred during deployment: Exception while deploying the app [sks3] : Invalid TYPE-level #EJB with name() = [] and beanInterface = [class java.lang.Object] in class Webservice.MeasurementResources. Each TYPE-level #EJB must specify both name() and beanInterface().at org.glassfish.apf.AnnotationInfo#3b63118a. Please see server.log for more details.
/home/philipp/NetBeansProjects/sks3/nbproject/build-impl.xml:1028: The module has not been deployed.
See the server log for details.
BUILD FAILED (total time: 6 seconds)
I dont have a clue what is going wrong but according to the message it has to be in the file MeasurementResurces.java ...
/*

package Webservice;
import Exception.DALException;
import dal.MeasurementDao;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.inject.Inject;
import javax.inject.Named;

public class MeasurementResources {
#Inject
MeasurementDao mDao;
public void add(Measurement arg) throws DALException{
mDao.save(arg);
}
/* public void getAll(Measurement arg) throws DALException{
mDao.getAll();
}
*/
}
Someone has at least a hint whats the problem?

Answer 1

You are using a Type-Level EJB without declaring name and beanInterface.
/**
*
* #author philipp
*/
//#Stateless
//#inject
#EJB(name="MyEjb", beanInterface=RemoteEjb.class)
//#LocalBean
#Named
#Path("Measurement")
public class MeasurementResources {
#Inject
MeasurementDao mDao;
public void add(Measurement arg) throws DALException{
mDao.save(arg);
}
}
#Remote
public interface RemoteEjb {
public void doSomething();
}
#Stateless
public class MyEjb implements RemoteEjb {
...
}
name is the name of the EJB you trying to inject. beanInterface is the Local or Remote interface. It's not a real injection. It is a way to use annotation as a replacement of deployment descriptor ejb-ref element. You should use a JNDI lookup in order to inject the ejb.
I don't know what are you trying to do but the common way to inject an ejb is the following:
#Named
#Path("Measurement")
public class MeasurementResources {
#EJB
private MyEjb myejb;
#Inject
MeasurementDao mDao;
public void add(Measurement arg) throws DALException{
mDao.save(arg);
}
...
}
