Hmm, the http connection has settings for max post size but I'm not sure it's related. Have you tried the tomcat way and setting maxPostSize (can probably be done in web.xml)
Add this to your web.xml:
do you know if there is a limit supported for max-file-size on WildFly?
Thanks in advance.
in wildfly, there is maximum post limit defined on listener.
by default it is limited to 10MB, you can change that by configuring max-post-size parameter to something else.
