Hi Burton,
The issue is with a simple HTTP request the file object is null, see the red
log entry below. But if I use a simple jQuery ajax call, it works as expected
and I’m not sure why and how to rectify.
This was the simple code I used to upload the file, same set of interceptors,
same action, same method and it works:
jQuery.ajax({
type: 'POST',
url: $form.attr('action'),
cache: false,
contentType: false,
processData: false,
data: formData,
success: function (response) {
if (response.success) {
console.log(“success, file uploaded
successfully”);
} else {
console.log(“failure, file upload failed to
execute successfully”);
}
},
error: function (err) {
console.log("Error ajax submission : ", err);
}
});
The log files now include:
action.IndexAction (IndexAction.java:54) - Uploaded file :
/apache-tomcat-9.0.44_base/work/Catalina/localhost/caams/upload_eabd436d_0fdd_4ff7_a598_b9a19724d8dd_00000000.tmp
action.IndexAction (IndexAction.java:55) - Uploaded file name : Invoice -
1331-1.pdf
action.IndexAction (IndexAction.java:56) - Uploaded file type : application/pdf
action.IndexAction (IndexAction.java:57) - Uploaded file length : 0
whereas with an HTTP request the logs looked like this:
action.IndexAction (IndexAction.java:54) - Uploaded file : null
action.IndexAction (IndexAction.java:55) - Uploaded file name : null
action.IndexAction (IndexAction.java:56) - Uploaded file type : null
action.IndexAction (IndexAction.java:57) - Uploaded file length : 0
I’m trying to understand why the same action method works with the ajax
requests but not plain HTTP requests?
Finally, 6.3 doesn’t have the
org.apache.struts2.interceptor.ActionFileUploadInterceptor in the jar so I
can’t see how we could test?

I'm not exactly sure what isn't working for you, but have you tried
using the newer FilesUploadAware interface? More information can be
found at https://struts.apache.org/core-developers/file-upload.html

I might also recommend you set <constant name="struts.devMode"
value="true"/> to see if anything comes up in the logs.
Thanks,
Burton
