ExtDirectSpring is a library that connects Ext JS (3.x,4.x,5.x,6.x) and Sencha Touch 2 JavaScript applications with Spring 3 MVC back ends. The library implements the Ext.Direct specification. It supports all the features of Ext.Direct, from simple remote calls to form posts with file upload.

To make a server method accessible it needs to be annotated with @ExtDirectMethod and it has to be a member of a Spring managed bean.

    @Service
    public class TestAction {
    
      @ExtDirectMethod
      public long multiply(long num) {
        return num * 8;
      }
    }

and then call the method from JavaScript

    testAction.multiply(2, function(result) {
      Ext.MessageBox.alert("Result", result);
    });
