问题 I was creating file upload using ExtJS 4 frontend and Spring 3 as backend. File upload works, but the response from server has wrong content type. When I send {success:true} using Map<String, Object> serialized by Jackson, ExtJS returns error Uncaught Ext.Error: You're trying to decode an invalid JSON String: <pre style="word-wrap: break-word; white-space: pre-wrap;">{"success":true}</pre> Why is my response wrapped with <pre> tag?

问题 We're thinking about replacing FusionCharts with ExtJS charts in our application, since: We already use ExtJS for our entire UI.
