Dear all,
I have the following code:
ScriptEngine engine = new GremlinScriptEngineFactory().getScriptEngine();
List<Vertex> results = new ArrayList<Vertex>();
engine.getBindings(ScriptContext.ENGINE_SCOPE).put("g", getGraph());
engine.getBindings(ScriptContext.ENGINE_SCOPE).put("v", getVertex(startNode));
engine.getBindings(ScriptContext.ENGINE_SCOPE).put("results", results);
try {
engine.eval(v.outE('KNOWS').inV >> results");
} catch (ScriptException e) {
logger.error(e.getMessage(), e);
}
....produces the following error:
ERROR javax.script.ScriptException:

And the alternative method:
Gremlin.compile("outE('KNOWS').inV)";
gives:
