I have a request from a customer. He wants to do the following:
I'm not familiar with OBIEE but I have used the Neo4j JDBC a bit so I assume it'll be similar usage.
Install/register/copy the Neo4j JDBC with OBIEE like any other SQL JDBC driver. The application is going think it's like any other SQL driver. Supply the credentials and host. Then in the query part, instead of SQL, just provide your cypher query. You'll want your cypher results to be tabular.
Here's a link to me but post I wrote doing this using Pentaho as an ETL tool with Neo4j
