I'm considering evaluating GWT to replace a Flex application, can someone tell me if in principal I can use external JavaScript libraries (the one i'm specifically conserned about is https://github.com/emilkm/amfjs) . basically I need to call java classes on a backend tomcat server to send and receive data.
Thx
Jens

Yes, you can define Java APIs in GWT that directly call external JavaScript. GWT itself uses the same technique to emulate JRE classes and map them to JavaScript if possible (e.g. java.util.Date is mostly mapped to JavaScript Date).
In older GWT versions (below 2.8.x) the technique is called JSNI
but it's use is discouraged because future versions of GWT will not support it anymore. The replacement is called JsInterop and you can get an in-depth overview at
