I like gremlin. It is a very good way to query the graph. I did played around with the gremlin console and did some queries on the trophic-graph. That worked pretty good.
In the afternoon I tried to integrate Groovy/Gremlin with Java. I wanted to implement the LocationDao in Groovy. In that way that we can work inside the DAO directly with Gremlin. Unfortunately without success. I got always some wired Exceptions. ClassCastExceptions and MethodeNotFoundExceptions or UnvalidArgumentExceptions. I am very disappointed about the bad integration between Groovy and Java. It is more hard that it should be.
Anyway. I decided to go back to the "walk on bones" strategie. I started to implement the DAO with pure Java and Neo4J. Without the fancy groovy gremlin lib. But I left the groovy gremlin stuff in the code base. If I have more patient for it I will try it again.
