[orientdb] How to get the value of a vertex in json, java graph api?

[Academia Learning Centro de inglés y de formación]

I am using this but I can not get its json value, only the OrientVertex

Iterable<OrientVertex> resultEhr = graph.command( new OCommandSQL("select 
from EHR where ehrId = '" + ehrId + "'") ).execute();
    if (resultEhr.iterator().hasNext()){
    Vertex ehr = (Vertex) resultEhr.iterator().next();      
    }


Any suggestions? Thanks!
