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对象访问 SimpleService.java 中divide方法。 返回结果(reply.getResult();)赋值给d3Handle.
如此简单清晰的方法调用，实在是简洁。慢慢的进入buffalo,就可能清楚的明白它的原来。没什么好说的，再清楚不过的代码了。if try it first yourself again when you konw it very well.
