Java jena fuseki set OntModelSpec pellet reasoner

the following code is used to send rdf data to a sparql endpoint.
It has worked fine until i've tried to add a reasoner to the OntoModel.
Now the compiler says:
"cannot convert from com.hp.hpl.jena.ontology.OntModelspec to org.apache.jena.ontology.OntModelSpec".
So my question is, what i have to edit to let it works?
(I know that the problem is obviusly in "PelletReasonerFactory.THE_SPEC" which is not from com.hp.hpl..., so is there something similar to this one, which also come from org.apache.jena... ?)
package services;
import org.apache.jena.query.DatasetAccessor;
import org.apache.jena.query.DatasetAccessorFactory;
import org.apache.jena.query.QueryExecution;
import org.apache.jena.query.QueryExecutionFactory;
import org.apache.jena.query.QuerySolution;
import org.apache.jena.query.ResultSet;
import org.apache.jena.query.ResultSetFormatter;
import org.apache.jena.rdf.model.Model;
import org.apache.jena.rdf.model.ModelFactory;
import org.apache.jena.rdf.model.RDFNode;
import org.apache.jena.ontology.OntModel;
import org.mindswap.pellet.jena.PelletReasonerFactory;
import org.apache.jena.ontology.OntModelSpec;
class FusekiExample {
public void addRDF(File rdf, String serviceURI){
throws IOException {
// the next commented line is the old working version...
//Model m = ModelFactory.createDefaultModel();
//these lines are the modified version which doesn't work.
OntModelSpec oms = PelletReasonerFactory.THE_SPEC;
OntModel m = ModelFactory.createOntologyModel(oms);
...
}

It looks like your PelletReasoner is very old and still uses the old jena libraries and not the newest one.
You need to find a newer version of your reasoner to work with the current jena or you need to work with an older jena version.

NodeBuilder not found in the ElasticSearch API application

I am trying to implement the Elasticsearch API. I have errors with the system accepting nodeBuilder. Here is the code -
import org.elasticsearch.action.index.IndexResponse;
import org.elasticsearch.action.update.UpdateRequest;
import org.elasticsearch.client.Client;
//import org.elasticsearch.common.settings.ImmutableSettings;
import org.elasticsearch.common.settings.*;
import org.elasticsearch.ElasticsearchException;
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.action.search.SearchType;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.node.NodeBuilder.*;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.common.unit.TimeValue;
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.search.SearchHit;
// on startup
Node node = nodeBuilder().node(); // nodeBuilder not recognised.
Client client = node.client();
// on shutdown
node.close();
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>2.2.0</version>
</dependency>
Client is recognised. Any ideas?

ClientBuilder is removed in ES API 5.
You can use org.elasticsearch.common.settings.Settings.builder() which will give you an instance of Builder.
Exp :
Settings.Builder elasticsearchSettings =
Settings.builder()
.put("http.enabled", "true")
.put("index.number_of_shards", "1")
.put("path.data", new File(tmpDir, "data").getAbsolutePath())
.put("path.logs", new File(tmpDir, "logs").getAbsolutePath())
.put("path.work", new File(tmpDir, "work").getAbsolutePath())
.put("path.home", tmpDir);

NodeBuilder has been removed. While using Node directly within an application is not officially supported, it can still be constructed with the Node(Settings) constructor.
Refer- https://www.elastic.co/guide/en/elasticsearch/reference/5.5/breaking_50_java_api_changes.html

org.elasticsearch.node.Node node = org.elasticsearch.node.NodeBuilder.nodeBuilder().node();
I have some dependencies also using node and hence the system could not resolve the elasticsearch one. The qualification resolved it.

UnsatisfiedLinkError when calling new World()

My error:

And this occurs when I do this:
world = new World(new Vector2(0, -9.81f), true);
I have looked online, and some solutions included using this:
import com.badlogic.gdx.utils.GdxNativesLoader;
GdxNativesLoader.load();
However, I don't know where to put this function, and if it even works (I tried putting it in several different places)
How can I fix this issue?
Help will be appreciated, thanks!
As requested, here are my imports:
import static com.example.blockbunny.handlers.B2DVars.PPM;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.math.Vector2;
import com.badlogic.gdx.physics.box2d.Body;
import com.badlogic.gdx.physics.box2d.BodyDef;
import com.badlogic.gdx.physics.box2d.BodyDef.BodyType;
import com.badlogic.gdx.physics.box2d.Box2DDebugRenderer;
import com.badlogic.gdx.physics.box2d.FixtureDef;
import com.badlogic.gdx.physics.box2d.PolygonShape;
import com.badlogic.gdx.physics.box2d.World;
import com.example.blockbunny.handlers.GameStateManager;
import com.example.blockbunny.main.Game;

I used Box2d several time with libgdx and i never encountered such a problem :
here what i propose t you :
GdxNativesLoader.load();
should be put on the create() method, but that doesn't seem to work with you
also try call it in a static way like this :
static {
GdxNativesLoader.load();
}
but i thin your problem is the extension of the library that you are using
verify that you are using gdx-box2d and not gdx-box2d-gwt which is used only for Html project
Verify that you are using the right (jar file) /(extension library) : gdx-box2d.jar and gdx-box2d-natives.jar (also verify the build path)
also try :
upgrade the box2d version that you're using
those were all the arrows i had ! hope one of it will work
Good luck !!

I came across the same issue, was using the gwt libraries. Updated the Maven dependency artifact from
gdx-box2d-gwt
to
gdx-box2d
and it fixed the error.

Drools 6.0 dynamically load rules at runtime

I want to load a drl file at runtime. The posts I've found including this one work for version 5.0 but I can't figure out how to do it for drools version 6.0.

In Drools 6, your rules packages are deployed to Maven. A KieScanner is provided, which you can attach to your KieContainer. This polls your repository at a defined interval to see whether a package has been updated and downloads the latest if that's the case.
A full explanation of how to define a KieScanner (including code samples) is provided in the Drools documentation here:
https://docs.jboss.org/drools/release/latest/drools-docs/html/ch04.html

I used info taken from those two docs:
https://docs.jboss.org/drools/release/6.0.1.Final/drools-docs/html_single/#d0e109
https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test/java/org/drools/compiler/CommonTestMethodBase.java
I've came out with this snippet that loads rules defined in the /drl/file/path file into the stateful session you obtain at the last line.
File path = new File("/drl/file/path");
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newFileResource(path), ResourceType.DRL);
if (kbuilder.hasErrors()) {
throw new RuntimeException("Errors: " + kbuilder.getErrors());
}
kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
Some methods are deprecated, so, don't expect this solution to be valid in the following releases.
Please, double check the imports, they are all from org.kie, not from drools packages. I admit those imports are too much, but I'm pasting the code from an example I'm trying to develop, so I have more things on my code, sorry for that.
import java.io.File;
import org.kie.api.KieServices;
import org.kie.api.builder.KieBuilder;

Javascript to Java communication using LiveConnect not working

I've been working on a project that requires communication both directions between Java and JavaScript. I have successfully managed to get it working under all browsers in OS X, but I'm now faced with the challenge of getting it to run on Windows under any browser. At the moment it simply doesn't work.
I'm just wondering if there is something special I need to do in order for JavaScript to communicate with Java?
My applet code looks like this:
<applet id='theApplet'
code="com/company/MyApplet.class"
archive="SMyApplet.jar"
height="50" width="900"
mayscript="true" scriptable="yes">
Your browser is ignoring the applet tag.
</applet>
Once the applet has loaded, I then try to call functions on it like this:
alert("Call some java:" + theApplet.testFunc());
And in the firebug console I get the following error:
theApplet.testFunc is not a function
I can confirm that this doesn't work in IE either.
When the page loads, I have the java console open and I can see that the applet is successfully loading and ready to accept calls.
Any help would be greatly appreciated!
Cheers
Update: Here is the stripped down java code exposing the public api that I'm trying to call.
package com.company;
import com.google.gson.Gson;
import java.applet.*;
import java.io.*;
import java.net.*;
import java.security.AccessController;
import java.security.PrivilegedAction;
import java.util.*;
import javax.xml.namespace.QName;
import javax.xml.stream.XMLEventReader;
import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLStreamConstants;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.events.*;
import netscape.javascript.*;
public class MyApplet extends Applet implements Runnable
{
public void init()
{
JSON = new Gson();
isReadyVar = 0;
workThread = null;
}
public void start()
{
}
public void run()
{
System.out.println("Done");
}
public void stop()
{
}
public void destroy()
{
}
/* Public API */
public int testFunc()
{
return 200;
}
}
Update [SOLVED]:
I figured out what the problem was exactly. Turns out the Gson lib I was using wasn't signed; but my own jar was. Browsers on windows require that all libs are signed; so I packaged Gson in with my java files & signed the lot and it solved the problem! Thanks for everyones help!

alert("Call some java:" + document.getElementbyId("theApplet").testFunc());
Make sure the testFunc() method is declared as public access.
If that does not work, post the applet code as an SSCCE.

Since the applet element is deprecated, I use following code, which works at least in Firefox:
<object id="MyApplet" classid="java:com.example.myapplet"
codetype="application/java" codebase="bin/" height="10" width="10"
</object>
