SimpleService.java

package net.buffalo.demo.simple;

import ;

public class SimpleService {
 
 public double divide(double a, double b) {
     System.out.println("Calling Divide,a="+a+", b="+b);
  try {
      Thread.sleep(1000);
  } catch (Exception e) {
      e.printStackTrace();
  }
     return a/b;
 }

}

 buffalo.remoteCall("simpleService.divide",[double1,double2], function(reply) {
  d3Handle.value = reply.getResult();
 })
buffalo對象訪問 SimpleService.java 中divide方法。 返回結果(reply.getResult();)賦值給d3Handle.

如此簡單清晰的方法調用，實在是簡潔。慢慢的進入buffalo,就可能清楚的明白它的原來。沒什么好說的，再清楚不過的代碼了。if try it first yourself again when you konw it very well.
