Thanks Dave for prompt reply.
Yes, I have defined inputStream property in action class like below.
*private InputStream inputStream;
public InputStream getInputStream() {
return inputStream;
}
public void setInputStream(InputStream inputStream) {
this.inputStream = inputStream;
}
*
One more thing that I missed in earlier message, I am getting exception even
before my action method "upload" getting invoked. I have few System.Out in
method, I don't see them in log..it seems to me request is failing before
upload method call...
public String upload() {
try{
UserTO userTo = this.getCurrentUser();
System.out.println("myPhotoFileName:"+myPhotoFileName);
System.out.println("myPhoto:"+myPhoto);
System.out.println("getMyPhotoContentType:"+
this.getMyPhotoContentType());
if ((myPhotoFileName != null && "".equals(myPhotoFileName)) ||
myPhoto == null) {
inputStream = new
StringBufferInputStream(this.getText("required.userPhoto"));
return Action.SUCCESS;
} else if (myPhoto.length() > 200000) {
inputStream = new
StringBufferInputStream(this.getText("userPhoto.maxLengthExceeded"));
return Action.SUCCESS;
}
if (!getMyPhotoContentType().startsWith("image/")) {
inputStream = new
StringBufferInputStream(this.getText("userPhoto.invalidPhotoType"));
return Action.SUCCESS;
}
// Some File Upload logic...
inputStream = new StringBufferInputStream(myPhotoFileName + "
added to your profile.");
}catch(Exception exp){
LOG.error("Exception in Photo Upload:", exp);
inputStream = new StringBufferInputStream("Photo upload failed.
Please try again later.");
}
return Action.SUCCESS;
}
