Ohh sorry about my current configuration that I shared but I was trying many
options. First I was trying exactly refer to the documentation but I did not
have success.
1. According to the docs, it’s unnecessary put interceptor refer again, because
defaultStack consider use actionFileUpload interceptor but I referred manually.
(I suppose that is necessary but I was trying without both refers,
actionFileUpload and defaultStack and nothing)
2. Mi jsp looks like this:
<s:form action="myAction" enctype="multipart/form-data" method="POST">
<s:file name=“upload” label=“Select a file” />
<s:submit>Upload</s:submit>
</s:form>
3. As you can see first I am trying to test a basic example because I’d
like to understand how do I upload a file in the new version because I am
migrating an app.
Finally I did not understand if you had success to upload a file to the server.
It is true?
That’s why I ask for your support.
I appreciate your assistance.
Regards
