issue with Upload File with Primefaces - jsf

Question

I'm trying insert a download in my webApplication.
First of all the page which contains the form where there is the is on
citizen/createparty.xhtml
And the folder where i'd like to upload the file is
partysymbols/ ..
Then i show to you the XHTML code:
<h:form enctype="multipart/form-data">
<p:fileUpload value="#{partyCreationBean.file}" mode="simple" />
<p:commandButton value="Submit" ajax="false" actionListener="#{partyCreationBean.upload}" />
Then the partyCreationBean
private UploadedFile file;
public UploadedFile getFile() {
return file;
}
public void setFile(UploadedFile file) {
this.file = file;
}
....
public void handleFileUpload() {
File target = new File(FacesContext.getCurrentInstance().getApplication().get);
System.out.println("handle file upload: " + file.getFileName());
InputStream inputStream;
try {
inputStream = file.getInputstream();
OutputStream out = new FileOutputStream(file.getFileName()
);
int read = 0;
byte[] bytes = new byte[1024];
while ((read = inputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
inputStream.close();
out.flush();
out.close();
System.out.println("done");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void upload() {
if(file != null) {
FacesMessage message = new FacesMessage("Succesful", file.getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, message);
handleFileUpload();
}
}
In my web.xml
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>
org.primefaces.webapp.filter.FileUploadFilter
</filter-class>
<init-param>
<param-name>thresholdSize</param-name>
<param-value>51200</param-value>
</init-param>
<init-param>
<param-name>uploadDirectory</param-name>
<param-value>partysymbols</param-value>
</init-param>
</filter>
The problem is that I reach the
System.out.println("done")
but I have no idea of where the file is uploaded.
then also, if i understood well the "uploadDirectory" parameter in the web.xml is not to set the directory where the file is setted.
I don't really understand how to do this stuff, also because it's first time that i work for a webapplication, and i use glassfish, and i have no idea about how the file system should work... I mean... i don't know where in reality are the pages and all the stuff... i just know where they are inside eclipse :/
Thankyou a lot in advance

I guess there is an error in your handleFileUpload() method:
The line
OutputStream out = new FileOutputStream(file.getFileName());
should probably be:
OutputStream out = new FileOutputStream(target.getAbsolutePath() + file.getFileName());
This should also be the path where the file finally is stored, you can print it with:
System.out.println("Path: " + target.getAbsolutePath() + file.getFileName());
The line where the target var is initialized in your code seems to miss something but I guess it retrieves the uploadDirectory param from the web.xml.
You may have to set up an absolute path for the uploadDirectory param like "c:\\tmp\\partysymbols" (Windows) or "/home/user/partysymbols" (Unix) in your web.xml.
