Struts 2 file upload : File object being null

Question

I am trying to use Struts 2 file upload but it seems to me that its not working. Below is my code.

UploadAction.java:

public class Uploa         


        

Answer 1

Change this

to

Your setter in your action class is setUpload so it is looking for a request parameter called upload, not file. For the sake of convention you should also change

private File file;

public void setUpload(File file){
    this.file=file;
}

to

private File upload;

public void setUpload(File file){
    this.upload=file;
}
