The main() pass the required file and then just the GUI loads because we
have to deal with a text field where user enter his name and we will create
individual of that name.
The main purpose of this code is to create individual (after user enter the
name) and store it locally in a file *(either a separate file or to the
file we have read **InputStream in =FileManager.get().open(file);*)
It writes the required result to the console(model.write method) but when I
try to write it in a file, it just remove all the data from the destination
file and even the ontology URI.
For writing to a file, I used these both methods but both does not work.
(1) FileWriter out = new FileWriter( fileName );
try {
model.write( out, "RDF/XML-ABBREV" );}
2) FileOutputStream out=new FileOutputStream(filename);
RDFWriter d = model.getWriter("RDF/XML-ABBREV");
d.write(model,out,null);
}catch(Exception e) {}
