public class A{
private void javaMethod(int a,int b){}
private native void init()/*-{
function OnMouseMove(e) {
//blow calling doesn't work
this.@p::javaMethod(Ljava/...teger;Ljava.../Integer;)(intVal,intVal);
}
}-*/;
}
As described above,how to make that invoking work?

Copied here for reference and convenience:
First, int is not java.lang.Integer, so your method signature in JSNI is wrong; it should read javaMethod(II).
(I suppose the @p:: while javaMethod is defined in class A is over-simplification in your question, but is OK in your code)
You'll also probably have a problem with this, that might not be what you think it is. A common pattern is to assign the current object (this, at the time) to a variable that you'll reference from your closure:
var that = this;
…
function OnMouseMove(e) {
[email protected]::javaMethod(II)(intVal, intVal);
}
You're doing two things wrong:
You're not defining the class name after @p, (assuming @p is actually just a shortened version of the real package's name);
You're attempting to pass java.lang.Integer in place of int. You should be saying (II) as the types, as described here.
Your code should look more like this:
package com.my.package;
public class ClassA {
private static void javaMethod(int a, int b) { ... }
public static native void init() /*-{
$wnd.javaMethod = function(a, b) {
return @com.my.package.ClassA::javaMethod(II)(a,b);
}
function OnMouseMove(e) {
$wnd.javaMethod(a,b);
}
}-*/;
}
this to be something it's not.
