How to make p:fileUpload work? - jsf

Question

So guys , I've decided to do a college's "homework" using JSF 2.2 and PrimeFaces 5.0 and theoretically I'm at the end , but I have great difficulty uploading files and , after trying by the whole day , I decided to post. The problem is that the file does not go where it should go, but the method is performed and shows no errors and exceptions.
page.xhtml
<p:fileUpload id="msg"
fileUploadListener="#{processoCtrl.handleFileUpload}"
allowTypes="/(\.|\/)(doc|docx|pdf)$/" mode="advanced"
sizeLimit="10485760"
invalidFileMessage="Formato de arquivo inválido"/>
<p:messages id="messages" showDetail="true" autoUpdate="true" closable="true"/>
ManagedBean
public void handleFileUpload(FileUploadEvent event) {
ExternalContext extContext = FacesContext.getCurrentInstance().getExternalContext();
// I already tryed //WEB-INF// , \\WEB-INF\\ e \WEB-INF\ (who knows...)
File result = new File(extContext.getRealPath("/WEB-INF/" + event.getFile().getFileName()));
System.out.println("/WEB-INF/" + event.getFile().getFileName());
try {
FileOutputStream fileOutputStream = new FileOutputStream(result);
byte[] buffer = new byte[6124];
int bulk;
InputStream inputStream = event.getFile().getInputstream();
while(true) {
bulk = inputStream.read(buffer);
if (bulk < 0) {
break;
}
fileOutputStream.write(buffer, 0, bulk);
fileOutputStream.flush();
}
fileOutputStream.close();
inputStream.close();
FacesMessage msg = new FacesMessage("File Description", "file name: " +
event.getFile().getFileName() + " file size: " +
event.getFile().getSize() / 1024 + "Kb content type: " +
event.getFile().getContentType() + "The file was uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
} catch (IOException e) {
e.printStackTrace();
FacesMessage error = new FacesMessage(FacesMessage.SEVERITY_ERROR, e.getMessage(), "erro.");
FacesContext.getCurrentInstance().addMessage(null, error);
}
}
