# Updating the Chart component with changes to the Corda Server servlet

By default, the Chart component is configured to look for the local instance of the Corda Server servlet, and fails if the servlet is not deployed.

You can change where the Chart component looks for Corda, if you are installing the servlet on a non-localhost machine or you have a Corda server already running elsewhere.

By default, the Chart component is configured to use a Corda Server deployed as a servlet on the same application server as the Discovery Framework. This is a convenient configuration for single-server deployments and development and demonstration environments. However, production environments (especially those with clustered application servers) may require alternate configuration to specify a separate location for the Corda Server.

The internal and external hosts used by Corda Server differ in cases where Corda is deployed as a standalone server and cases where Corda is deployed as a servlet.

- When deployed as a servlet, the internal and external URL typically take a form similar to http://server.example.com:[app server port]/corda/server.
- When deployed as a standalone server, the internal and external hosts typically take a form similar to http://cordaserver.example.com:[corda server port]/ (where the Corda server port differs for the internal and external URLs). For details, refer to the Corda documentation.
