[jira] Created: (CXF-2234) Unmarshalling with JAXB of a method that
is defined in an inherited interface results in an NPE exception
Unmarshalling with JAXB of a method that is defined in an inherited interface results in an NPE exception
---------------------------------------------------------------------------------------------------------
Key: CXF-2234
URL: https://issues.apache.org/jira/browse/CXF-2234
Project: CXF
Issue Type: Bug
Components: JAXB Databinding
Affects Versions: 2.2.2
Environment: WindowsXP-SP3, Eclipse 3.4
Reporter: Tom
The UserService:
@javax.jws.WebService
public interface UserService extends AbstractService<User, Users>
{
}
The AbstractService:
@javax.jws.WebService
public interface AbstractService<T, Ts>
{
public Ts list();
}
The UserServiceImpl:
@javax.jws.WebService(endpointInterface = "nl.knowledgeplaza.profiler.services.UserService", serviceName = "users") // the "ws" prefix is handled by the container
public class UserServiceImpl
implements UserService
{
public Users list()
{
try
{
if (slf4j.isDebugEnabled()) slf4j.debug("list User");
// find all
List<User> lList = User.findAll();
if (slf4j.isDebugEnabled()) slf4j.debug("list User size={}", lList.size());
// create a collection so JAXB knows what to do
Users lUsers= new Users(lList);
// done
return lUsers;
}
catch (RuntimeException e)
{
slf4j.error(ExceptionUtil.describe(e), e);
throw e;
}
}
}
UnitTests start the SOAP end point as follows:
javax.xml.ws.Endpoint.publish(cWSUserAddress, new UserServiceImpl());
The unittest:
@org.junit.Test
public void listUsersSOAP()
{
// create a proxy to the service
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.getInInterceptors().add(new LoggingInInterceptor());
factory.getOutInterceptors().add(new LoggingOutInterceptor());
factory.setServiceClass(UserService.class);
factory.setAddress(cWSUserAddress);
UserService lUserService = (UserService)factory.create();
// make the call
Users lUsers = lUserService.list();
// check it
org.fest.assertions.Assertions.assertThat( lUsers.getUser().size() ).isGreaterThan(0);
}
The call arrives serverside, the code is correctly executed and 4 User entities have been fetched from the database. The JAXB marshalling then runs into problems, resulting in a value of null being returned on the clients side, and failing the unittest on a NPE.

The Users class is just a collection workaround as suggested in CXF's documentation:

public class Users

{
public Users() { setUser(new ArrayList<User>()); } // upon JAXB unmarshalling of an empty collection, the setUser is NOT called and the collection would be null instead of empty
public Users(Collection<User> c) { setUser(c); }

public void setUser(Collection<User> c) { iCollection = c; }
public List<User> asList() { return new ArrayList<User>(iCollection); }
}

[jira] Commented: (CXF-2234) Unmarshalling with JAXB of a method
that is defined in an inherited interface results in an NPE exception
Posted by "Tom (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CXF-2234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712106#action_12712106 ]
Tom commented on CXF-2234:
--------------------------
I attached the source, but it's a "what's the most efficient approach" thingy. My classes are relating to all kind of other things like FEST reflection. I believe it would be much more efficient to take an existing "list" alike method using JAXB, and simply move that into a inherited interface. If you then get the same exception, you won't have to work through my sources, nor do I need to shop out a working example. If not, then we can see if I should sharpen my axe.
The sniplets wee there to explain the setup, but you should mimick it in an existing unit test.

[jira] Updated: (CXF-2234) Unmarshalling with JAXB of a method that
is defined in an inherited interface results in an NPE exception
Posted by "Tom (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CXF-2234?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tom updated CXF-2234:
---------------------
Description:
The UserService:
@javax.jws.WebService
public interface UserService extends AbstractService<User, Users>
{
}
The AbstractService:
@javax.jws.WebService
public interface AbstractService<T, Ts>
{
public Ts list();
}
The UserServiceImpl:
@javax.jws.WebService(endpointInterface = "nl.knowledgeplaza.profiler.services.UserService", serviceName = "users") // the "ws" prefix is handled by the container
public class UserServiceImpl
implements UserService
{
public Users list()
{
try
{
if (slf4j.isDebugEnabled()) slf4j.debug("list User");
// find all
List<User> lList = User.findAll();
if (slf4j.isDebugEnabled()) slf4j.debug("list User size={}", lList.size());
// create a collection so JAXB knows what to do
Users lUsers= new Users(lList);
// done
return lUsers;
}
catch (RuntimeException e)
{
slf4j.error(ExceptionUtil.describe(e), e);
throw e;
}
}
}
UnitTests start the SOAP end point as follows:
javax.xml.ws.Endpoint.publish(cWSUserAddress, new UserServiceImpl());
The unittest:
@org.junit.Test
public void listUsersSOAP()
{
// create a proxy to the service
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.getInInterceptors().add(new LoggingInInterceptor());
factory.getOutInterceptors().add(new LoggingOutInterceptor());
factory.setServiceClass(UserService.class);
factory.setAddress(cWSUserAddress);
UserService lUserService = (UserService)factory.create();
// make the call
Users lUsers = lUserService.list();
// check it
org.fest.assertions.Assertions.assertThat( lUsers.getUser().size() ).isGreaterThan(0);
}
The call arrives serverside, the code is correctly executed and 4 User entities have been fetched from the database. The JAXB marshalling then runs into problems, resulting in a value of null being returned on the clients side, and failing the unittest on a NPE.

[jira] Commented: (CXF-2234) Unmarshalling with JAXB of a method
that is defined in an inherited interface results in an NPE exception
Posted by "Tom (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CXF-2234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712006#action_12712006 ]
Tom commented on CXF-2234:
--------------------------
Oh, the same method is also called through REST (but I removed the corresponding annotations from the sniplets) and there it works ok.
If the list method is placed in the UserService interface instead of the inherited interface, the unittest also runs correctly.
Both point above suggest to me that the problem is infact not a JAXB problem, but a SOAP-using-JAXB problem.

[jira] Updated: (CXF-2234) Unmarshalling with JAXB of a method that
is defined in an inherited interface results in an NPE exception
Posted by "Tom (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CXF-2234?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tom updated CXF-2234:
---------------------
Description:
The UserService:
[code]
@javax.jws.WebService
public interface UserService extends AbstractService<User, Users>
{
}
[/code]
The AbstractService:
@javax.jws.WebService
public interface AbstractService<T, Ts>
{
public Ts list();
}
The UserServiceImpl:
@javax.jws.WebService(endpointInterface = "nl.knowledgeplaza.profiler.services.UserService", serviceName = "users") // the "ws" prefix is handled by the container
public class UserServiceImpl
implements UserService
{
public Users list()
{
try
{
if (slf4j.isDebugEnabled()) slf4j.debug("list User");
// find all
List<User> lList = User.findAll();
if (slf4j.isDebugEnabled()) slf4j.debug("list User size={}", lList.size());
// create a collection so JAXB knows what to do
Users lUsers= new Users(lList);
// done
return lUsers;
}
catch (RuntimeException e)
{
slf4j.error(ExceptionUtil.describe(e), e);
throw e;
}
}
}
UnitTests start the SOAP end point as follows:
javax.xml.ws.Endpoint.publish(cWSUserAddress, new UserServiceImpl());
The unittest:
@org.junit.Test
public void listUsersSOAP()
{
// create a proxy to the service
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.getInInterceptors().add(new LoggingInInterceptor());
factory.getOutInterceptors().add(new LoggingOutInterceptor());
factory.setServiceClass(UserService.class);
factory.setAddress(cWSUserAddress);
UserService lUserService = (UserService)factory.create();
// make the call
Users lUsers = lUserService.list();
// check it
org.fest.assertions.Assertions.assertThat( lUsers.getUser().size() ).isGreaterThan(0);
}
The call arrives serverside, the code is correctly executed and 4 User entities have been fetched from the database. The JAXB marshalling then runs into problems, resulting in a value of null being returned on the clients side, and failing the unittest on a NPE.

that is defined in an inherited interface results in an NPE exception
Posted by "Daniel Kulp (JIRA)" <ji...@apache.org>.

Daniel Kulp commented on CXF-2234:
----------------------------------
You can PROBABLY get around this by adding an @XmlSeeAlso annotation pointing at the Users class to the service interfaces. JAXB SHOULD then be able to pick it up.
