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.

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?

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()]));

For some additional info. I was getting the same exception. What I found is that I needed to call the "setCellValueFactory" method when setting up the TableColumn instances. I was mistakenly calling "setCellFactory".
You may try the below link it works fine. For Further assistance you have to provide code.
Populate a tableview using database in JavaFX
Since you're specifying how to populate the values of the column, make sure to use the setCellValueFactory method.
