Simplest <s:fileUpload> usage
I've been hanging around for almost two weeks just to make <s:fileUpload> working.
Simply want to add upload file capability to seam-registration. I'm using seam-space
sample as reference and adapt it into stateless version. Not refering to wiki's
samples cause it using tomahawk, I just want to have it plain and simple.
Environment used :
- JBoss AS 4.0.5.GA
- JBoss Seam 1.2.0.Patch1
- JBoss IDE for Eclipse
- default JBoss Seam (upload) jars - no tomahawk.jar, no icefaces, no commons-upload.
- jboss-seam-ui.jar included

package myapp;

@Local
public interface AdminI {
public void parse() throws Exception;
public byte[] getUploadedFile();
public void setUploadedFile(byte[] uploadedFile);
}No error, but it always print "uploadedFile is null". What requirements I might missed?
Any help will be appreciated.
