[FIXED] How to solve RequestTooBigException: UT000020: Connection terminated as request was larger than 10485760 in Wildfly?

Issue

I have a web application in Wildfly and when I'm trying to upload a file bigger than 10MB, I'm getting the following error:

io.undertow.server.RequestTooBigException: UT000020: Connection terminated as request was larger than 10485760

Please, how can I solve this error?

Solution

I solved my problem by putting the max-post-size in the standalone.xml, as the example below:

<subsystem xmlns="urn:jboss:domain:undertow:3.1">
<buffer-cache name="default"/>
<server name="default-server">
    <ajp-listener name="ajp" max-post-size="1073741824" socket-binding="ajp"/>
    <http-listener name="default" max-post-size="1073741824" socket-binding="http" redirect-socket="https"/>
    <https-listener name="https" max-post-size="1073741824" socket-binding="https" security-realm="ApplicationRealm"/>
    ...
</server>
...

In this example, the value is configurated to 1GB, but you can configure the value you want.

If you use Nginx, don't forget to configure the client_max_body_size.
