Increase file upload size in wildfly

To increase file upload size limit in wildfly, the steps are as follows:

1. Go to bin directory in wildfly (assuming your wildfly directory is located in /opt), and connect to wildfly console

# cd /opt/wildfly/bin

# ./jboss-cli.sh -c

2. Go to /subsystem=undertow/server=default-server/http-listener=default

[standalone@localhost:9990 /] cd /subsystem=undertow/server=default-server/http-listener=default

3. Increase max-header-size to a higher value

[standalone@localhost:9990 /] :write-attribute(name=max-header-size,value=30000000)

{

    "outcome" => "success",

    "response-headers" => {

        "operation-requires-reload" => true,

        "process-state" => "reload-required"

    }

}

4. Increase max-post-size to a higher value

[standalone@localhost:9990 /] :write-attribute(name=max-post-size,value=30000000)

{

    "outcome" => "success",

    "response-headers" => {

        "operation-requires-reload" => true,

        "process-state" => "reload-required"

    }

}

5. Check if both is now increased in value

[standalone@localhost:9990 /] ls

max-header-size=30000000

...

max-post-size=30000000  

You are all set, test upload using your application to verify the change. Restart wildfly if necessary.
