ES doesn't work with rexster gremlin extension

[Aaliyah]

the problem is like the topic. I'm not sure if I misunderstood something or 
I missed some configurations. The ES works fine in usual situations, but 
doesn't work with rexster gremlin extension. 

In java, I configured the graph as follows:





In the extension, I wrote:

*String query = "v." + propKey + ": (" + propValue + ")"; *

*if(((TitanGraph) graph).indexQuery("search", 
query).vertices().iterator().hasNext()){...}*

When I invoked the extension, the rexster told: null pointer exception, 
unknown index, etc. As follows:





After this, I searched some advices from google and made some 
configurations in rexster.xml



Then, the problems seemed as another way. (As you can see, first_example is 
the name of the graph.)



Besides, when I invoked the extension, I've been told: the graph is 
non-configured.



I've also tried the embedded mode. The problems seem to be the same.

Plus,  I'm using:

Titan 0.4.2

 Tinkerpop 0.2.4

 Cassandra 2.0.7

ElasticSearch 1.2.1 


This problem's driving me crazy. Any pointer would be appreciated! Thanks 
in advance!
