Liferay multiple portlets running with same embedded neo4j db

Question

Using spring data neo4j in liferay portlets, Neo4j is locking itself when a portlet is using it, encounter exception like below

Unable to lock store [db.name], this is usually a result of some other Neo4j kernel running using the same store

Is there any way to run multiple portlets with same embedded neo4j db. Can i use Neo4j HA ? Looks like Neo4j HA to going to deal with multi-servers, but i only one server. Any ideas?

Thanks in advance!

Answer 1

Did you try including neo4j library files at portal level instead of using at portlet level ? ie to place required .jar files in /lib/ext instead of inside WEB-INF of every portlet.

I'm not an expert in neo4j, but having good experience with liferay. Suggesting above solution from liferay point to ensure common place for all portlets.
