Adding external WMS via cesiums default proxy

CesiumJS
1

I have an external WMS url to add it in cesium application. I am using tomcat server to host the cesium application. Below is my code
new Cesium.WebMapServiceImageryProvider({

url : ‘http://sgu.se/geoserver/yyyyyy/wms’,

layers : ‘zzzzz’,

proxy : new Cesium.DefaultProxy(’/proxy/’),

parameters : {

transparent : ‘true’,

format : ‘image/png’

}

})

``

Do i need to do anyother additional configuration?

Are there any error messages in the console?
