Configure Tomcat Parameter Limits

Due to a change in Tomcat defaults relating to multipart forms, the following configuration adjustment is currently required when upgrading to Tomcat version 9.0.106 (or above).

In Tomcat 9.0.106 there is a new default setting that restricts multipart forms to a maximum of 10 parts. This setting is too low to support the form functionality on the SuperWEB2 Custom Data page.

WingArc may address this in a future release through changes to the underlying form structure on that page, but in the interim you will need to change a setting in Tomcat’s server.xml file to increase the limit from the default:

1. Open <tomcat_home>/conf/server.xml in a text editor.

2. Locate the following section, which defines the main connector for the server:

   CODE

       <Connector port="8080" protocol="HTTP/1.1"
                  connectionTimeout="20000"
                  redirectPort="8443"
                  maxParameterCount="1000"
                  />

3. Add the maxPartCount parameter, with a value of 100:

   CODE

       <Connector port="8080" protocol="HTTP/1.1"
                  connectionTimeout="20000"
                  redirectPort="8443"
                  maxParameterCount="1000"
                  maxPartCount="100"
                  />

4. Save your changes, and restart Tomcat or the SuperWEB2 service.
