I am new to Protege API and I have just created on Eclipse a small application which uses an external OWL file. Also I did import all the necessary libraries.
import java.util.Collection;
import java.util.Iterator;
import edu.stanford.smi.protege.exception.OntologyLoadException;
import edu.stanford.smi.protegex.owl.ProtegeOWL;
import edu.stanford.smi.protegex.owl.model.*;
public class Trial {
public static void main(String[] args) throws OntologyLoadException {
String uri = "C:/Documents and Settings/Anto/Desktop/travel.owl";
OWLModel owlModel = ProtegeOWL.createJenaOWLModelFromURI(uri);
Collection classes = owlModel.getUserDefinedOWLNamedClasses();
for (Iterator it = classes.iterator(); it.hasNext();) {
OWLNamedClass cls = (OWLNamedClass) it.next();
Collection instances = cls.getInstances(false);
System.out.println("Class " + cls.getBrowserText() + " ("
+ instances.size() + ")");
for (Iterator jt = instances.iterator(); jt.hasNext();) {
OWLIndividual individual = (OWLIndividual) jt.next();
System.out.println(" - " + individual.getBrowserText());
}
}
}
}
When I do compile however I get the following errors:

Does anyone have an idea on where the problem should be?
Replace
String uri = "C:/Documents and Settings/Anto/Desktop/travel.owl";
with
String uri = "file:///C:/Documents and Settings/Anto/Desktop/travel.owl";

I'm executing a Babelfy program:
Here's the code:
import it.uniroma1.lcl.babelfy.Babelfy;
import it.uniroma1.lcl.babelfy.Babelfy.Matching;
import it.uniroma1.lcl.babelfy.Babelfy.AccessType;
import it.uniroma1.lcl.babelfy.data.Annotation;

import it.uniroma1.lcl.babelnet.BabelSense;
import it.uniroma1.lcl.babelnet.BabelSynset;
import it.uniroma1.lcl.jlt.util.Language;
public class Example
{
public static void main(String[] args) throws Exception
{
Babelfy bfy = Babelfy.getInstance(AccessType.ONLINE);
BabelNet bn = BabelNet.getInstance();
String word=" ";
String inputText = "He has a passion for music";
Annotation annotations = bfy.babelfy("3697a512-bfd4-427e-846d-9eb60f98c3bb",inputText,Matching.EXACT,Language.EN);
System.out.println("inputText: "+inputText+"\nannotations:");
for(BabelSynsetAnchor annotation : annotations.getAnnotations())
{
word=annotation.getBabelSynset().getId();
System.out.println(annotation.getAnchorText()+"\t"+word+"\t"+annotation.getBabelSynset());
//BabelSynset by = bn.getSynsetFromId(("bn:03083790n"));
for (BabelSense sense : bn.getSynsetFromId((word)))
{
if(sense.getSource().toString().equals("WN"))
System.out.println("Sense: " + sense.getLemma()+ "\tSource: " + sense.getSource().toString());
}
}
}
}
And here's the error thrown:
Exception in thread "main" java.io.FileNotFoundException: http://babelfy.org/rest?text=He%20has%20a%20passion%20for%20music&key=3697a512-bfd4-427e-846d-9eb60f98c3bb&partMatching=false&lang=EN&format=json

Apart from the FileNotFoundException, why is there a '0' in the error at:
sun.net.www.protocol.http.HttpURLConnection.getInputStream0(Unknown Source)
Does it imply anything else?

It appears you're using Modbus4J. It is based on jSSC (Java Simple Serial Connector) for serial communication, so make sure that jSSC is found while compiling (you may need to download it separately, since you're getting a ClassNotFoundException related to a jSSC class).
I don't know about any tutorial but I may suggest you to take a look at the Modbus4J forum archive. Here's a simple Modbus RTU example.
I don't know why my code java is not compiled.
I need to index my database with solr.
I launch my server with line commande .

How to resolve this problem?
Sounds like you haven't added the httpclient jar (from dist/solrj-lib) to your classpath.
See the Solrj wiki page topic about: Setting the Classpath

I have included all the Hector api jars in the classpath and I do not know what is causing this error. Can someone please explain the reason for the error?
It seems you're missing some 3rd party libraries (in this case, Thrift which I believe contains the TTransportException class). Add all required libraries to your classpath too, and let's see if that helps.
Check your "Run/Debug Configurations" under settings.
Ascertain the name of the "main class" you are using. Click to select the name of your current class. Apply. Ok.

it is getting compiled successfully, but throwing this runtime exception (i am providing correct required credentials as arguments).

I am sure, i am missing something, but enable to resolve it.
You seem to be missing a dependency. Download this google-collections and add the jar to your build-path.
