Hello, In tracebacks, the most helpful information is often at the end. Here, it says: 'Layer "world" not defined.' which is pretty clear (that's not always the case). I think your XML configuration file does not have any layer name "world" whereas your request shows LAYERS=world amond other parameters.
If you need to test your WMS connection, I recommand you use a WMS client. There are several OpenSource options: QGIS or uDig would fit. Such software will handle all the necessary parameters. Once your WMS server is OK, you can build an OpenLayers application which also acts as a WMS client but requires a little more configuration. Please refer to the OpenLayers website and mailing lists for information on how to do this.
