Error with Neo4J @Indexed property

[killersite]

Please try my JUnit tests at https://github.com/killersite/Neo4JSpatialTests

When I try to use neo4j-spatial with a @NodeEntity(partial=true) I always get NPE of the following kind.

java.lang.NullPointerException
	at org.neo4j.gis.spatial.pipes.GeoPipeline.startNearestNeighborLatLonSearch(GeoPipeline.java:363)
	at org.neo4j.gis.spatial.indexprovider.LayerNodeIndex.query(LayerNodeIndex.java:249)

and the SpatialRepository interface Repositories don't work either...

java.lang.NullPointerException
	at com.ex.domain.Restaurant_Roo_JavaBean.ajc$interMethodDispatch1$com_ex_domain_Restaurant_Roo_JavaBean$com_ex_domain_Restaurant$getName(Restaurant_Roo_JavaBean.aj)
	at com.ex.graph.RestaurantSpatialTest.testFindByName(RestaurantSpatialTest.java:59)

I am having a hard time understanding why my tests are failing. If you could take a look at them and let me know what I am doing wrong I would appreciate it.

Thanks,
Ben

Help.

Anyone try the Neo4J unit test in https://github.com/killersite/Neo4JSpatialTests ?

cross-store entities are causing NPE errors with the following tests.

@Test
	public void testFindWithinDistance() {
    	Iterable<Restaurant> venus = restaurantService.findWithinDistance(16,56,70);
        assertThat(asCollection(venus), hasItems(restaurant));
	}

	@Test
	public void testFindByName() {
		Restaurant foundvenu = restaurantService.findByName("test");
		assertEquals("test", foundvenu.getName());
	}

Thanks,
Ben

Ben,

I had a look. I don't think it is cross-store stuff that is the problem. Instead, here are a couple of changes that move the tests into green (some other tests are red for me though, due to Roo/ AspectJ stuff):

In RestaurantServiceImpl:
public void saveRestaurant(Restaurant restaurant) {
        restaurantNeoRepository.save(restaurant);
//        restaurant.persist();
    }

In RestaurantSpatialTest-context.xml:
<neo4j:config storeDirectory="target/servicetest"/>

In VenueSpatialTest-context.xml:
<bean id="graphDatabaseService" class="org.neo4j.test.ImpermanentGraphDatabase" destroy-method="shutdown"/>
<neo4j:config storeDirectory="target/venuetest"/>

Hope that helps!

Regards,

Lasse

Thanks for the response Lasse.

Except you're proving my point that cross-store is the problem. In order to save the Entity in the SQL database I have to use -

<neo4j:config graphDatabaseService="graphDatabaseService" entityManagerFactory="entityManagerFactory"/>

without the entityManagerFactory attribute it is straight Neo4J. Right?

Also VenueSpatialTest.java should be "green" without any changes. That is there to demonstrate what you showed with the changes to RestaurantSpatialTest.java - without an entityManagerFactory the test passes fine.

Please help. Thanks.

HELP - Can anyone make my Neo4j-spatial junit tests pass against cross-store Entities?
https://github.com/killersite/Neo4JS...atialTest.java

Do you have a simple JUnit test showing the findWithinDistance method working against cross-store Entities?
