Question

This is a follow-up to what I was trying to accomplish here https://stackoverflow.com/questions/7313922/uploading-files-ussing-myfaces-tomahawk-jsf-2-0

I’ve managed to get the image as an UploadedFile Object, but I can’t seem to be able to save it to disk. I want to save it locally (in C:\Temp, for example) such that when I run my app, I can upload a file (test.jpg, for example) from my desktop and see it saved on the server (for example, in C:\Temp).

My bean is pretty simple:

import org.apache.myfaces.custom.fileupload.UploadedFile;
public class PatientBB {  

private UploadedFile uploadedFile; 

public UploadedFile getUploadedFile(){
return this.uploadedFile; 
}  
.
public void setUploadedFile(UploadedFile uploadedFile){     
this.uploadedFile = uploadedFile; 
} 
.
public String actionSubmitImage(){
//This is th part I need help with. how do I save it in my C?
}

I greatly Appreciate all the help, thank you!

As far as I can tell, according to the javaDoc, you should be able to do

uploadedFile.getInputStream();

and then push the data from that to a FileOutputStream.

Psuedo:

 InputStream is = uploadedFile.getInputStream();
 byte[] buffer = new byte[uploadedFile.getLength()); //This can be more space-efficient if necessary
 is.read(buffer);
 File f = new File("C:\\tmp\\" + uploadedFile.getFilename());
 f.createNewFile();
 FileOutputStream fos = new FileOutputStream(f);
 fos.write(buffer);

Does that make sense? Is that what you’re looking for?
