Can't get management instance of graph - gremlin

I connect to gremlin server from gremlin console:
:remote connect tinkerpop.server config/connect_config.yaml
I can execute queries like:
:> graph.getGraphName()
:> g.V().count().next()
:> g.V().drop().iterate()
:> g.V().values('LOL')
and many others. g - GraphTraversalSource, graph - StandardJanusGraph.
I need to configure schema of graph:
:> mg = graph.openManagenet()
but when i try to execute this query, i get exception:
gremlin> :> mngmt = graph.openManagement()

Can somebody say me what i must do to fix this problem?

I'm not sure that the ManagementSystem is serializable so that's why you are getting that error. There are at least two ways to sort it out. First, you didn't post what is in your config/connect_config.yaml but I assume it is not using this sort of configuration option for the serializer:
hosts: [localhost]
port: 8182
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV3d0, config: { serializeResultToString: true }}
By using the serializeResultToString option (and assuming that serializer is configured in Gremlin Server in its configuration) you tell Gremlin Server to take any result you get and call toString() on it before it is returned. In that way, you never get serialization errors.
But, the downside is that you only get String values back. Generally speaking, I would think that is ok for most Gremlin Console interactions (especially administrative ones like the one you are trying to execute with the ManagementSystem API. So, if you wanted to continue using your current configuration which tries to serialize actual "objects" you just need to be sure your scripts only return data that is serializable so instead of:
:> mg = graph.openManagement()
do
:> mg = graph.openManagement();[]
which doesn't return mg, but rather an empty list.

Getting can't serialize access exception for task in SCDF

We are using SCDF 1.2.3.RELEASE (Local Server) for calling different task created using spring cloud task 1.2.2.RELEASE which is internally using batch jobs for the actual job. Both of these SCDF and the task are using the same Oracle DB.
When we trigger a task from already registered on SCDF, sometimes we can see the start time for that task but the overall initialization of the task gets failed with the following error

Please let us know how can we solve this "can't serialize access for this transaction" exception
Thanks
This is a Spring Batch issue (not a Spring Cloud Task one). Try changing the transaction isolation level to ISOLATION_REPEATABLE_READ.

}
At first I tried to add the libraries to EJB. After that I added it to WEB-INF/lib and to EAR/lib. But the error remains the same.
So where and how do I have to include external JAR library files with a common Software API to have access to them in my JSF Webaplication?
If you have an example or how to, it would be very, very nice!
Thank you!

I can recreate your problem pretty easily if I execute the :plugin command against the 2.x version of Gremlin Console. :plugin is a new command for TP3. Are you sure that you are using the right version?

plugin activated: tinkerpop.server

Your console should look something like the above to use the :plugin command.

ClassCastException Runtime Error

I am trying to read website URLS, remove HTML tags, tokenize them, then put them for POS tagging.
It does all the above steps fine but breaks at the POS tagging. The error is coming from thePOSTagging class, anyone figured where I'm going wrong?
Exception in thread "main" java.lang.ClassCastException: java.lang.String cannot be cast to java.util.ArrayList

The error is quite straightforward, (you're casting a String to ArrayList in line 29 of POSTagging.java), but I can't see that happening.
What I do see is, you can't cast a Object array to a String array. You're doing:
taggers[0] = new OpenNLP((String[]) a.toArray());
Instead, use:
taggers[0] = new OpenNLP(a.toArray(new String[a.size()]));
