I have installed titan-server-0.4.4 to use rexster to load titan graph. Now that I can use http://localhost:8182/doghouse/main/gremlin/graph but don't know why the gremlin console is not working. I might have been doing it wrong but don't know which part I'm doing wrong.

Gremlin 2.4.0

gremlin>graph = TinkerGraph.open()

==>javax.script.ScriptException: groovy.lang.MissingMethodException: No signature of method: static com.tinkerpop.blueprints.impls.tg.TinkerGraph.open() is applicable for argument types: () values: [] Possible solutions: grep(), grep(java.lang.Object), e([Ljava.lang.Object;), use([Ljava.lang.Object;), use(java.util.List, groovy.lang.Closure), use(java.lang.Class, groovy.lang.Closure)

gremlin> graph = TinkerFactory.createModern()

==>javax.script.ScriptException: groovy.lang.MissingPropertyException: No such property: TinkerFactory for class: Script5`

I tried with titan-1.0.0-hadoop1, and gremlin query worked fine, but had to change to server-0.4.4 to use rexster to display graph.

Thank you in advance

You are mixing and matching syntax/technology from TinkerPop 2.x with 3.x. Rexster is a TinkerPop 2.x based system. You are trying to then use TinkerPop 3.x based Titan 1.0 with Gremlin syntax like TinkerFactory.createModern() and TinkerGraph.open() that creates TinkerGraph databases as part of Titan. I would say:

  1. Don't use anything TinkerPop 2.x at this point. That version has not been maintained for many years.
  2. Do not use Titan - it is no longer maintained. Consider JanusGraph (Titan's successor) or other TinkerPop 3.x systems.
  3. If you are just getting started with graphs/TinkerPop, then simply start with TinkerGraph and Gremlin Console. Follow the Getting Started Tutorial and then read the Gremlin Console Tutorial. Finally, get familiar with the Practical Gremlin book.
