SDN 2.1.0.RC1 NullPointerException in DelegatingGraphDatabase.getIndex()

[VladoK]

Hi,
I try to upgrade SDN from 2.1.0.M1 to 2.1.0.RC1 but there is NullPointerException while loading ApplicationContext. Please, look at my simple example project in attachment. I changed only SDN version from 2.1.0.M1 to 2.1.0.RC1 and neo4j from 1.6 to 1.7 in maven pom.xml.

Thanks Vladok for sharing, I'll have a look.

There seems to be a change how the Spring Dependency resolution is done between 3.0.7 and 3.1.0

When I update your project to 3.1.0.RELEASE it works, just as a heads up, I'll continue to investigate.

[MichaelHunger]

It seems to be that the @Configuration class @Bean methods are called before any fields or setters are @Autowired leaving depdencies unmet, there have been some changes in the ordering and setup of the internal dependencies which seem to cause this behavior to surface.

I tried a few ways of counteracting that but so far none has worked.

Hi Michael,
thank you for your reply. I will update Spring Framework too.

[zgdnba]

i also meet the same issue when i want to implement the same function in no-maven project, i just touch neo4j 1 week, after i made lots of compare, i found if have one @Service class in you project, then can resolve this exception, and can start Tomcat from eclipse successful, but i cannot get the template. it is null.

[MichaelHunger]

zgdnba what Spring version are you using?

Michael

[zgdnba]

3.0.7, actually i used the sample code of "cineasts", i want to transfer this project from manve to common Dynamic web project. same jars from that project be dependency in pom.xml

[MichaelHunger]

Can you upgrade it to 3.1.0 and see if the error still ocurrs?

[zgdnba]

i made some test by 3.1.0 also, same issue with 3.0.7, but add at least one @Service for any one class, then can resolve this exception, and i also resolved the template = null issue for now.
